A-1 Mold Pro President: Dana Belletete P.O. Box 83, Lochmere, NH 03252 (603) 661-6311 www.a1moldpro.com A1MoldPro@metrocast.net FINAL MOLD INSPECTION REPORT Prepared exclusively for: Dawn & Dan Crim 86 Sarasota Lane Laconia, NH 03246 Dawn 603-556-9027 Dan 603-425-8975 Inspection Date: June 6, 2014 Page 1 of 19 BACKGROUND The subject Property is a Single Family Modular Home with attached 2 stall garage, located at: 86 Sarasota Lane, Laconia, NH 03246 (The Property). Attic studding is modular random spacing and mostly 16” on center. A-1 Mold Pro has been retained by Dawn & Dan Crim (the Client) to perform a visual full site inspection of the Property. The primary reason for the inspection was to determine the extent of water damages and possible hidden mold growth from poor construction methodologies. On June 6, 2014, A-1 Mold Pro representative and NAMP (National Association of Mold Professionals) Certified Mold Inspector, Dana Belletete (the Inspector) performed a mold/fungi assessment at the Property. The weather conditions at the time of the inspection were: Clearing and windy. The outside Relative Humidity (RH) was 55.1%, the outside Temperature was 65.3 Degrees Fahrenheit (°F), and the Barometer reading was 29.50 inches of mercury (Hg). FIELD OBSERVATIONS Date: 06/06/14 Time: 9:00 AM EST Inspector: Dana Belletete Client ID: DC060614 Client Names: Dawn & Dan Crim Property Address: 86 Sarasota Lane, Laconia, NH 03246 Weather: Clearing and windy: 65.3° F, 55.1% RH, Barometer: 29.50 Hg Noticeable Odor: YES, kitty litter boxes with cat urine like odor in basement area. CLIENT INTERVIEW Known Water Events: YES, Client indicated that the foundation has leaked since new and is still leaking. Water previously came through the radon vent stack when installed, leaking into the basement causing a 12 foot diameter puddle on the basement floor, this leak was fixed. Kitchen sink plumbing still leaks. Any Self-Remediation: YES, Client sealed the entire basement floor and walls, and attempted to patch and seal the foundation leak from the inside multiple times, but, it is still leaking. Improperly sized Dehumidifier was supplied by the builder, but, was not operating at this time and was not set up to automatically empty or pump out. Known Structural Defects: YES, Kitchen entry door doesn’t function or close correctly, so it can’t be used. Poured concrete basement floor has cracked everywhere and is Page 2 of 19 collapsing due to improper ground preparation. Modular sections where left 2 inches apart and not bolted together, (fixed now), however, there is still a gap between the modular sections in the rear where moisture and wind can penetrate. The basement lolly columns were not put in the proper places to support the structure, entire home is floating on the foundation walls with no fasteners through the sills, basement windows and door are improperly framed with large gaps between where the frames meet the foundation. The Client stated that the basement windows were not installed correctly with large gaps everywhere that he could put his fingers trough. Builders were asked to remove the windows and fix the framing fit but they just filled all gaps with foam. Kitchen sink drain plumbing has leaked since day one and still leaks into a container. Client indicated that all the nails on the sub-flooring in the bathrooms were rusted before the finished floors being installed indicating the bathrooms got wet before the finished flooring being installed, and no caulking was present around the tub/shower enclosures, he had to seal them himself to prevent future water damages. Water Stains Anywhere: YES, where the foundation crack is still leaking in the basement producing water puddles, stains and black mold growth on the floor. Occupant Health Issues: Symptoms for all occupants lumped together: abnormal urine in person now/frequent UTIs just like cat who died - screened for bladder/kidney cancer to no avail, abnormal pancreas - currently investigating, frequent swollen throat, frequent swollen gland under jaw, toothache above swollen gland - dentist doesn't understand why - could be due to swollen gland, chronic sinus issues, extremities twitch - this is new in recent weeks, frequent headaches, sleeping problems, digestive issues, hair loss, depression, fatigue, difficulty breathing, loss of voice frequently, memory issues, sores in mouth - told by dental hygienist - gastrointestinal related, and allergic shiners under eyes. They also had a cat die since moving in. Client asked for an autopsy because the cat got sick 1 year after moving here (urinary tract infections) and died the following year. The Vet told the Client that the cats lungs were inflamed, kidneys were damaged - he didn't know what would cause such a thing in a cat and that he was really, really sick.   Occupant Immune Issues/Asthma: YES, difficulty breathing. HVAC Filters/Humidifiers/Air Purifiers: YES, leaking non-HEPA Rated HVAC filter. Feel better outside of home: YES, they all definitely feel better when away for a weekend (not completely better, but better) - only to return home and feel horrible again. Remodeling or recent changes: NO, home is new! Other Noticeable Conditions: Client indicated Radon levels have climbed from what is normally .01 to .09 recently. Property has a Radon Mitigation System operating. Basement has a cat urine like odor she thought might be from mold, but, the Client does have cats and litter boxes in the basement. Page 3 of 19 HOME ENVIRONMENT RELATIVE HUMIDITY: Outside: 55.1% RH Garage: 61.4% Basement: 71.8% 1st Floor: 54.6% Attic: 36.9% RELATIVE TEMPERATURE: Outside: 65.3° F Garage: 62.0° F Basement: 62.2° F 1st Floor: 70.8° F Attic: 87.6° F Difference: + 6.3% Difference: + 16.7% Difference: - 0.5% Difference: - 18.2% Difference: Difference: Difference: + Difference: + 3.3° F 3.1° F DEW POINT 53° 5.5° F 22.3° F INSPECTOR’S OBSERVATIONS Inspection Areas (Exterior) The Inspector observed the general landscaping around the building was pitched toward the rear left walls and forces water to run along and build up against the entire length of left foundation wall areas. There was green algae growth along the left foundation wall in the patio area and the concrete wall was still visibly wet at this time. The Inspector observed (from ground level) that all the shingle based roof surfaces appeared to be in good condition at this time. There was the appearance of full length ridge venting and full length soffit vents around the perimeter of the roof overhangs, there were no gable vents visible. The Inspector observed a crack above the ground in the right side foundation wall directly under the furnace exhaust/intake plumbing. This foundation crack continued below ground level. The Inspector observed there were no gutters or other visible methods of water removal present around the perimeter of the Property roof edges, and only a few remnants of crushed stone were present along the right side of the Property foundation wall. The Inspector observed a large gap along the edge of the left rear basement window where it meets the rear poured concrete wall, and a large gap on the left side end basement window. Both of these gaps went down to or below ground level and appear to provide an easy place for water/moisture/insects to penetrate into the basement areas. INSPECTOR’S OBSERVATIONS Inspection Areas (Interior) (NOTE: All Protimeter readings at or above 20% RH on contact with materials are highlighted in RED since most mold activity normally requires at least 20% RH). Page 4 of 19 Using a general sampling technique, existing lighting, 10 Million Candle Power Flashlight, factory calibrated Digital Protimeter, factory calibrated Digital Hygro-Thermometer, factory Calibrated FLIR (Forward Looking InfraRed camera) (if required), Long Wave UltraViolet Light (if required), 36 inch Fiber Optic Bora-Scope (if required), the Inspector examined all visibly affected (targeted) areas of the Property. GARAGE: No visible mold or water stains in the attached 2 stall garage at this time. All soffit and ridge areas were wide open with visible daylight present. Exterior facing walls were uninsulated and unfinished. BASEMENT: The Client stated that the builder provider him a dehumidifier (50 pint) for the basement area, but, even with it running continuously, the basement walls remain wet to the touch most of the summer months and the majority of their stored items had thick green and gray mold growing on them and about $20,000 of them had to be discarded to date. This dehumidifier unit was not operating during the time of this inspection, but, it appeared insufficient to dry such a large area even if all the water intrusion issues were actually resolved and with standing water present, it would require emptying every couple of hours which could not be accomplished with a working couple. The Inspector observed a strong cat urine like odor in the basement area, but, using UV (Long Wave UltraViolet Light) did not find any areas where the cats urinated on the floors or walls. The urine seemed to be concentrated in the litter boxes only. There were a couple of 3 inch diameter spots on the concrete floor that appeared to be dried cat vomit but they did not account for the urine like odor. There was considerable amounts of dead worms accumulated in the front left and right corners of the basement area floor. No apparent source of entry was seen, but since they were in proximity to the utility entry points, they may be coming in through the water and sewer utility holes in the lower foundation front wall. It appears the cats may possibly be eating some of these worms and subsequently vomiting. The Inspector observed that the large gaps around the window and door frames were filled with either spray foam or packed with pink fiberglass insulation materials, apparently stopping the major wind/water intrusion for now in these areas, but the framing fit and structure was substandard with large gaps, especially around the basement exit door where there was room for and the need for an additional jack stud on at least the closure side of the door frame. The Inspector observed that there were no fasteners connecting the building with the foundation along any of the sill plates, and daylight could be seen through the large gaps between the sill plate joints. Two randomly spaced lolly columns where holding up single split pieces of horizontal 2x8 in the 3x12 foot indent in the left center foundation wall area. Unknown what their purpose was, but if extra support was needed, vertical triple or quad plated 2x8x12’s or a steel girder should have been installed to actually provide support there, not just the appearance of support. Page 5 of 19 The Inspector observed a considerable amount of items still being stored in the basement area, some were in plastic storage containers but the majority of the items were still in the moving boxes or in cloth based bags. There was visible mold growing on some of the lower sections of the cloth based bags. The Inspector observed a sealed plastic cover over a sump pump area that the Client indicated was installed for a sump pump if needed but silicone sealed during the Radon Mitigation procedures. The Client indicated that the improper ground preparation issues under the concrete slab can be viewed through this hole and would be a good place to start an inspection and diagnosis of the floor cracking, settling, and Radon issues. The Inspector observed daylight was visible around the basement exit door itself when fully closed, the door framing was missing double jack studs, and there was discoloring indicating possible mold growth on the pink fiberglass insulation materials to the left of the door around and above the dual light switches. Upon pulling the insulation materials (with the Clients permission) only small amounts of visible gray mold were seen on the back side of the insulation and the black spotting on the face of the insulation materials appear to be some form of ink/stain sprayed on them during construction. There were 2 holes bored through the sheathing for wiring purposes and daylight could be seen through them. The gray mold on the underside of the insulation materials corresponded to the location of these open holes which need to be sealed water tight from the outside elements to prevent further issues there. The Inspector observed food stuffs stored on shelving in the basement area and based on the lab results or for common sense reasons, all the exterior surfaces of the food stuffs stored in the basement area should be externally cleaned with 91% Isopropyl Alcohol before being opened and consumed, or these items should be discarded. The only bare poured concrete foundation wall area was at the floor to ceiling crack that had been patched multiple times by the Client. The remainder of the basement walls and floor were sealed by the Client to reduce moisture levels. There was still standing water on the floor in this cracked area along with some black mold growth and water staining. The lower leaking wall/floor area indicated 27.5% RH on contact at the base and 15.8% RH on contact at the top of the wall that was above ground outside, and 79.6% RH at the top to 99.9% RH at the base under their surfaces. The sealed basement left foundation walls indicated 91.6% RH at the top and 99.5% RH at the bottom below their surfaces and 14.2% RH at the top and 22.3% RH at the base on contact. Meaning the majority of the lower basement walls and floor areas were damp enough to promote mold growth on most items placed in direct contact with or against them. FLIR indicated damp around and at the base of the floor to ceiling foundation crack and at the lower left corner of the basement exit door, and in both of the areas where the walls join the floor along the front of the basement where the worms seem to gather. Page 6 of 19 With the Clients permission, the Inspector removed a section of insulation from the basement ceiling area and visible mold growth was present on the sides of the joists and minor black mold was present on the edge of one of the joist. Black flakes and black ink/ stain was present on some of the pink insulation materials in this area. The underside of the 1st-floor particleboard sub-flooring appeared visually normal at this time in this area. The Inspector observed gray surface mold under the stairs on most of the framing materials. It appears that this mold may be caused from sustained high humidity levels in the basement area most likely from water evaporating from the foundation crack leak puddles formed nearby. With the Clients permission, the Inspector removed the access cover for the HVAC unit and observed possible white mold growth under the blower area along with dust and debris in the blower chamber and the air return chamber. The filter separating the two areas was in good shape and clean, but there were large enough gaps along both sides of the front edge of the filter to allow air and any possible mold spores, odors, and dust to bypass the filter and circulate throughout the Property. Normally a metal cover plate seals the filter in the chamber, but this was not present. 1ST FLOOR: The Inspector observed a sizable gap under the basement to 1st floor door, that the customer had to retro fit with a device to close the 2 inch gap across the bottom, trying to prevent mold, odors and cold wind from blowing up into the kitchen and living room areas from the wet basement. The Inspector observed a full length stress crack in the ceiling from the entry door to the cellar door about in line with the open kitchen/living room areas. Kitchen entry door could not be opened to be inspected since its fit and finish was so bad it can’t be used. It leaks air around its entire sealing area, and is pole wedged shut for energy savings. The Client indicated that there are ice dams and large icicles being formed over the patio roof area along the left side of the Property. FLIR indicated possible damp or insulation issues present there, but, the Protimeter indicated relatively dry up to 2.5 inches deep from the inside walls at this time. FLIR indicated possible damp spots or insulation issues in the majority of the upper kitchen and living room areas, lower garage entry door wall areas, right of the lower TV area wall, left and right of the master bedroom wall/ceiling joint areas and etc. For a modular factory built home, one would expect much better insulation and prevention against possible condensation moisture in the walls and ceiling areas than what was seen at this time. Laboratory results will determine if invasive inspection will be required. The Inspector observed there was no outside venting above the stove area, just a microwave above the stove with a recirculating fan. The wall behind the electric stove is the basement stairwell wall, so framed over ducting would be required to vent the stove Page 7 of 19 fumes and moisture directly outside. It did not appear that this lack of venting would create and sustain high enough mold growing humidity conditions on its own, but, it could definitely contribute to the overall moisture levels when combined with all the other direct air leaks and insulation issues seen throughout the Property. The Inspector observed a single patch of what appeared to be imbedded black mold in the right side sheetrock wall of Austin’s bedroom closet (first bedroom on left). The area was dry at this time and no water sources were nearby, it appears to be caused by a one time water event of unknown source, cleaning with 91% Isopropyl Alcohol, BIN priming, and repainting is all that’s recommend for this one spot at this time, unless lab results indicate invasive inspection is necessary. The Client indicated that “Module C” was never attached to the rest of the modules when the Property was being assembled, leaving a 2 inch exposed gap all the way around it till finally being put in place and bolted together at some time in the past. Client’s FLIR ( in the winter), indicated a top to bottom gap still exists down the entire rear center of the Property modules. The Inspector could not duplicate this reading today due to very close indoor and outdoor temperature ranges. However, the gap was visible to the naked eye on both ends of the attic with lots of daylight shining between the center module seams. Although the moisture readings were high inside, no moisture build up was seen on the window frames or sash seams as the Client indicates happens all winter long. Again temperature ranges were not far enough apart to create these issues today. The Protimeter read 8.7% RH up to 2.5 inches deep below the majority or the suspect wall and ceiling surfaces and the wall behind the kitchen freezer and the lower wall sections to the left and right of the garage entry door read 9.8% RH. The parts of the wall that the FLIR indicated were dry in these areas; read a steady 6.1% RH below their surfaces. The Inspector observed an active water leak under the left kitchen sink drain assembly and the Client indicates both side of this sink has had leak issues since day one. He has tried multiple time to stop the leakage, but, to no avail. A catchment container remains under the left drain pipe and it had 2+ inches of water, soap scum, & etc., in it. The left sink strainer attachment nut does not contact and squeeze the rubber gasket at this time, and thick water stains and soap scum like residue cover the majority of the left drain plumbing and light amounts are seen on the drain plumbing under the right sink bowl, which wasn’t actively leaking at this time. The Client indicated that open gaps were present around both bathroom tub/shower assemblies. Upon occupying the premises the Client had to seal around these areas himself to prevent any water damages from occurring. Despite sealing them, the seam in the rear left corner of the hallway bathroom tub/shower assembly was starting to pull apart and open up to water intrusion again, due to the constant settling of the foundation. Page 8 of 19 The Inspector observed no high moisture or water issues around the over and under washer/dryer installed in the hallway closet. Due to its tight fit, it could not be determined if burst proof stainless hoses were installed to connect the washer. The Client indicated she smells various odors at different times around the sinks, but other than the known water leak and standing water under the kitchen sink, the remainder of the visible plumbing in both bathrooms appeared intact with no leaks or odors at this time. The FLIR indicated a possible damp spot to the lower right rear area of the master bath toilet and linoleum floor area, and Protimeter readings confirmed it was damp at 13.9% RH under the linoleum in just that area while the remainder of the flooring indicated 9.4% RH under its surfaces. No condensation moisture was seen under the toilet tank and the floor surfaces were dry at this time. A toilet flange seal leak can commonly cause intermittent odors and wick water under the linoleum causing hidden mold and decay so this area should be checked out. The Client indicated that mold keeps growing on the ceiling and upper wall areas above the shower/tub assemblies and they have to keep cleaning these areas. Minor mold was seen on the master bathroom upper wall by the shower head and one small dot on the ceiling, however, these areas had been recently cleaned again. Both bathrooms have high ceilings and operational exhaust vent fan assemblies that originally vented into the attic but now vent properly through the roof. Most likely the exhaust vent fan units are not properly sized for the space and appliances present, and the builders specs should be used to verify their actual capacity. This Inspector recommends that both bathrooms have fan/ vent units capable of moving at least 110 cuft/min. [New common building calculations say you should have 50 cuft/min for each appliance (sink/toilet/bidet), 100 cuft/min for each (shower/tub), and 200 cuft/min for each (Jacuzzi).] FLIR indicated a possible damp line or completely missing insulation, one bay to the left of the outside wall corner in Cody’s bedroom (rear most bedroom). It’s possible insulation was removed and/or the sewer vent stack or Radon stack runs through this area, but, without invasive inspection it was not possible to determine the exact reason for these readings. Protimeter indicated dry at 6.5% RH up to 2.5 inches into this wall area so no further actions were deemed necessary at this time. ATTIC: Access was through a medium sized scuttle located in the main hallway ceiling just above the rear most bedroom doorway entrance. (Cody’s room) The Inspector observed rafter studding was about 16 inch on center in some places, random centering in other places, and consisted of 2x6 rafters with particle board roof and end wall sheathing. Plenty of daylight could be seen through most of the soffit bay areas and ridge areas and no visible mold or signs of water leakage were seen at this time. There appeared to be adequate ventilation taking place. Page 9 of 19 There was some surface mold on some of the construction furring strips tacked to the rafters, but, these appeared to be nonstructural, and thus could just be removed and discarded, rather than spending any money on chemical remediation in the attic area at this time. They were probably already moldy and water stained before being tacked in during the construction or moving phases. The Inspector observed that the majority of the insulation was blown-in and random inspection under some of the insulation revealed no visible mold growth or water damages at this time. However, there was no indication of a vapor barrier between the ceilings and the attic areas. The Inspector observed distinct lines of daylight penetrating between where the left and right modules were supposedly joined together along both end walls and there was possible open air gaps along the top of both end walls allowing bees and wasps to build nests in the attic area. If a pest control specialist is employed for the worm issues, they should also look at the attic bee and wasp issues. The Protimeter read a steady 7.7% RH on contact with the rafters and underside of the particle board sheathing, indicating the attic materials were dry enough to discourage active mold growth at this time. Methodology To determine whether the Property has a serious mold problem, the Inspector uses a wide variety of testing techniques and technologies to take samples of possible mold/fungi growth and or visible mold/fungi contamination. The Inspector offers the Client the opportunity to have the mold/fungi samples taken by swab, slide, and or air sampling. The Inspector offers the Client the opportunity to have all visible mold/fungi sampled, grown, identified and counted by a qualified testing laboratory to genus level which is normally sufficient to determine infestation and evacuation levels. All samples are normally sent to the lab overnight and normally take about 7 days to incubate and get written results. The Client may elect to have samples analyzed to the species level as a premium service if serious health issues are present, however, this increases testing costs and turn around times may be go to 14-21 days. If gross contamination is detected, bulk sampling may also be used. Actual samples of existing carpet/wall board/sheathing/or other contaminated building materials may be collected and put into individual sample bags/containers for lab analysis. The Inspector also offers an air-sampling test for each floor level/room of the dwelling, and an outside air sample control test if any indoor air samples are indeed pulled. Considering a verbal discussion including all recommended testing and its related costs, the Client makes the actual determination as to what testing will actually be conducted. Therefore, it is possible that not all the recommended testing will be conducted, some species will remain undetected, and further testing may be necessary. Page 10 of 19 Health Effects Inhalation of fungal spores, fragments (parts), or metabolites (e.g. mycotoxins and volatile organic compounds) from a wide variety of fungi may lead to or exacerbate immunologic (allergic) reactions, cause toxic effects, or cause infections. Illnesses can result from both: high-levels, short term exposures and lower level, long-term exposures. The most common symptoms reported from exposures in indoor environments are runny nose, eye irritation, cough, congestion, aggravation of asthma, headache, and fatigue. In order for humans to be exposed indoors, fungal spores, fragments, or metabolites must be released into the air and inhaled, physically contacted (dermal exposure), or ingested. Whether symptoms develop in people exposed to fungi depends on the nature of the fungi material (e.g. allergenic, toxic, or infectious), the levels of exposure, and the susceptibility of exposed persons. Susceptibility varies with the genetic predisposition (e.g. allergic reactions do not always occur in all individuals), age, state of health, and concurrent exposures. For these reasons, and because measurements of exposure are not standardized and biological markers of exposure to fungi are largely unknown, it is not possible to determine “safe” or “unsafe” levels of exposure for people in general. Sampling Based on the previous substantial repetitive water events and visible mold growth in the basement area, possible damp or condensation/moisture areas indicated by FLIR, the Clients considerable health issues, and the possible adverse health effects that could be caused by mold, mold testing was recommended and some testing was conducted at the time of this inspection. A swab sample was plated from the HVAC blower chamber area (beyond the filter), an Air Sample was pulled from the basement, an Air Sample was pulled from the dining/living room area of the 1st Floor, an Air Sample was pulled from the 1st floor Master Bedroom area, and a control Air Sample was pulled about 10 feet away from the outside Front Entryway of the Property. Your actual test results are attached. Please read them to better understand the various types of mold spores found and their possible effects on human health. Interpreting Laboratory Results The following information can be used to better understand the laboratory results: Air Samples: Low <100 CFU/m3 Borderline 100 – 250 CFU/m3 Active Growth 250-1000 CFU/m3 Very Active Growth >1000 CFU/m3 TNTC = Too Numerous To Count Page 11 of 19 There currently are no NH or Federal standards or guidelines regarding results of mold/ fungal samples. NYC Guidelines are based on over 35 years of real world analysis in one of the largest rental populations in the US and is considered the mold standard “bible” by most mold professionals. There are no levels, which are typical or permissible. The above chart is based on historical analysis and experience and should not be used for health evaluation purposes. This report was developed according to the New York City Department of Health Bureau of Environmental & Occupational Disease Epidemiology “Guidelines on Assessment and Remediation of Fungi in Indoor Environments”. “Many fungi (e.g. species of Aspergillus, Penicillium, Fusarium, Trichoderma, and Memnoniella) along with Stachybotrys can produce potent mycotoxins. Mycotoxins are metabolites that have been identified toxic agents. Even low levels of these species should be remediated. For example, the New York City Guidelines recommend remediation if 1 CFU/m3 of Stachybotrys is found in the indoor air. If 1000+ CFU/ m3 of Stachybotrys is found in the indoor air, the guidelines recommend immediate evacuation.” Laboratory Results You may have a mold problem if indoor mold tests report mold levels that are (a) higher than the outdoor mold levels; (b) present indoors but absent from the outdoors; or (c) the indoor mold is pathogenic or allergenic. Testing Conclusion Based on the laboratory data, You had extremely high, Very Active Growth levels of YEAST growing in the kitchen/living room areas. YEAST is considered allergenic and one can develop hypersensitivity to it with repetitive or long term exposure. Some levels of YEAST were present in every indoor sample taken, and no YEAST was present outside, indicating it was indeed growing inside the Property. Furthermore, YEAST was present in the HVAC blower chamber indicating some amount of YEAST was being distributed throughout the Property every time the HVAC unit runs. You had Active Growth Levels of Aspergillus in the Basement Area and none was found in the outside air indicating it was growing in the Property Basement Areas. Aspergillus was present in the HVAC blower chamber indicating some amount of Aspergillus was being distributed throughout the Property every time the HVAC unit runs. The HVAC Unit was not operating during the time of this inspection which could explain why none was seen in the 1st floor air samples at the time the samples were taken. There was also Active Growth Levels of Cladosporium in the Kitchen/Living Room area. Although found in higher numbers outside (which is very common and normal), Page 12 of 19 Cladosporium can be a cause of extrinsic asthma, skin lesions, keratitis, onychomycosis, sinusitis, and pulmonary infections, thus even low levels of this should be remediated. Cladosporium was present in the HVAC blower chamber indicating some amount of Cladosporium was being distributed throughout the Property every time the HVAC unit runs. The levels of Cladosporium in the kitchen/living room were easily high enough to get pulled into the hallway air intake, where it would bypass or flow through the non-HEPA HVAC filter and leaking filter chamber, and then get blown back all over the Property interior each time the HVAC Unit operates. Some level of Cladosporium was found in every sample taken inside and outside. Inspection Conclusion The basement area is very damp and will only get worse as the summer time humidity increases outside and as more water pours into the basement through the floor to ceiling foundation wall crack. Any time the relative humidity in the basement area or any other area of the Property interior exceeds 20% RH on the surface of the building materials and/or 80% RH in the air, the mold will continue to grow and could eventually lead to structural decay and structural failure. The apparent moving, settling, and cracking of the foundation wall and floor areas may be responsible for some or all the: plumbing, shower/tub joints, window and door frame/ seal issues, possible insulation and moisture condensation issues in the wall/ceiling/floor joints, and etc. It appears poor business practices and possibly negligent construction techniques were employed throughout this buildings installation process, from improper ground conditioning, to lack of foundation drainage, to not placing or bolting modules as designed, to improper framing in the basement window/door areas, to a total lack of sill plate fasteners and possibly inadequate structural supports. All of these conditions appear to be contributing to the various air leaks and water, moisture, condensation, ice dam issues at different times of the year throughout the Property as witnessed by the Clients. Although the majority of the interior appeared relatively dry on the surface at this time, including up to 2.5 inches deep into the sheetrock/insulation materials there may be additional hidden water/mold damages and active mold growth taking place deeper in the exterior walls of the Property from the previous and continuing structural issues. If additional testing in the kitchen area does not indicate a source for the YEAST, invasive inspection into the kitchen/living room walls and possibly ceilings may be required. All plumbing throughout the Property should be inspected for leaks and damages from the building moving, and the active leak under the kitchen sink must be fixed immediately and the catch basin removed and discarded.

Recommendations The Inspector highly recommends that based on the high mold spore counts of possible allergenic and pathogenic mold spores present in the Property and in the HVAC Unit, coupled with the Clients current health issues and the subsequent health risk to all the occupants and pets, the Clients should seek alternate shelter (paid for by the builders or homeowners insurance) and the Property should remain vacant until all recommended remediation services have been completed. Final Air Quality Clearance testing is highly recommended once all work is complete to assure all hidden mold areas and the allergenic and/or pathogenic molds have been remediated and the non-allergenic or nonpathogenic mold spore counts and types are equal to or less than outside levels. Page 14 of 19 The Inspector highly recommends that if nothing else is going to be done at this time, and the Client wishes to continue to occupy the Property, at minimum the entire interior living spaces; walls, floors, ceilings, cabinets, closets, furnishings & etc. should all be fogged with an EPA approved fungicide as soon as possible, including the HVAC system. This is a stop gap measure to kill all current air borne & surface only mold spores. This process will not effect hidden live mold growth present, nor keep the mold spore count from increasing again inside the living areas or basement if the full remediation services recommended are not conducted. (See Estimate # 544) Regardless of whether this is done initially or not, once all recommended remediation efforts have been completed, and before any occupants return, the entire interior living spaces; walls, floors, ceilings, cabinets, closets, furnishings & etc., will need to be fogged with an EPA approved fungicide. The Inspector highly recommends that a complete basement to attic fungicide fogging be conducted throughout the Property once all remediation repairs have been completed, including Roto-brush HEPA cleaning of any HVAC metal based plenums, ductwork, vents, and intakes & etc., & fogging best effort of on the entire HVAC system. (See Estimate # 545) The Client should maintain properly sized HVAC filters, (1x16x25), the filters should be HEPA or Ultra HEPA in design, and the filter chamber for the HVAC unit should be sealed air tight with a proper metal cover/gasket assembly, or duct taped air tight over the exposed open filter end each time it is changed, to prevent any additional spore/dust/odor bypass from occurring in the now clean HVAC system. Considering this inspection, and the laboratory results, hidden mold growth is suspected in and underneath all the basement insulation and surrounding wood framed areas in contact with it. The Inspector highly recommends that to properly remediate these conditions, at minimum, with an air scrubber operating, all the basement insulation materials in the walls and ceiling areas need to be removed and disposed of and a minimum of a 2-step chemical remediation process needs to be conducted on all affected, exposed, salvageable, and accessible areas, including being “chased” at lest 1 foot beyond any visible damages in all directions, [~228 sqft for the basement stair areas, ~261 sqft for the door and window framed areas, and (unknown sqft amount until gutting is completed up to an additional +1125sqft for the basement ceiling areas)] (See Estimate # 546) Then, regardless of what areas may require a 2-step process, the entire basement area will need to be HEPA vacuumed and fungicide fogged after the foundation leak is proven sealed from the exterior of the foundation and all necessary 2step remediation has been completed. [This assumes the entire poured foundation floor and wall structures have been deemed salvageable by a structural engineer and all cracks and leaks have been repaired] The Inspector highly recommends that by whatever means necessary, all module sill plates be permanently fastened to the foundation walls, this would reduce some of the horizontal movement of the property modules, but, would not do much for the vertical movements still apparently present. Page 15 of 19 The Inspector highly recommends that the top to bottom foundation crack needs to be dug down below the poured concrete floor level, wire brushed, chemically cleaned, chemically sealed with a permanent waterproof sealant at least 3 feet wide (18 inches to each side of the crack), the actual crack should be sealed with a “Crack-Pac Injection Kit” or best effort with a flexible silicone based concrete sealant, then the entire foundation crack should be covered top to bottom with a crack centered 18” or 48” wide sheet of adhesive waterproofing material such as (Grace Ice & Water Shield), before being back filled and some type of surface drainage then being installed. (See Estimate # 547) Estimate does not include digging out and backfilling the suspect area. [Ideally proper foundation drainage should have been installed below the concrete floor level around the entire Property perimeter (daylighting beyond the rear stone wall) before any backfilling or landscaping taking place during the construction phase. This would be an expensive task now that everything is already buried and landscaped.] The Inspector highly recommends that all exterior gaps between the basement window frames and the poured concrete foundation walls should be sealed water/air tight with a flexible silicone based concrete sealant to prevent any further water/moisture/insect issues from occurring in these areas. All the sill plate gaps should be filled inside with expanding spray foam as should any other utility entry/exit points including the holes behind the insulation on the left of the basement exit door, and the gaps around the sewer and water pipes. Likewise all interior cracks and fissures should be sealed water tight with at least a flexible silicone based concrete sealant and all foundation framing gaps including sill plate seams and joints should be sealed water/air tight with expanding foam sealant inside. (See Estimate # 547) The Inspector highly recommends that once all exterior foundation cracks and gaps and all interior basement walls/floor area cracks and gaps are sealed best effort, that if the Radon readings still remain high, both a Radon Specialist and a Structural Engineer should be consulted to determine the cause for the increase in Radon levels, and also to determine if the poured concrete foundation/floor areas have finished settling or if they are likely to continue cracking and decaying as they settle further. Any advice should be followed to stop this settling process since it will lead to further foundation water/radon leaks through additional cracking, and could lead to complete structural failure over time. The Inspector highly recommends that either gutters be installed along the roof perimeters with down spouts connected to drainage that exits at least 6 feet out beyond the rear of the Property, or, alternatively, a trench at least 8 inches deep and 2.5 feet wide should be dug under all the roof perimeter areas, plastic sheathing should be installed against the foundation wall from ground level angled down and out 2.5 feet to the base of the trench, perforated 4” diameter drain pipe with silt sock should be installed on top of the plastic, pitched to a sealed 4” drain pipe that daylights at least 6 feet beyond the rear of the Property, preferably out over the rear stone wall areas on each side of the Property, then this trench should all be filled with crushed stone, 2.5 feet wide by 8 inches deep Page 16 of 19 (back to ground level). This would facilitate proper drainage without gutters and drastically reduce the amount of water building up against and along all the foundation side walls and also through the foundation crack. The Inspector highly recommends that a properly sized self pumping dehumidifier be installed in the basement area, drained into the existing HVAC condensation pump station, or connected to an inside sewer line with a trap, set to maintain 35% RH year round to assure no further moisture damage and mold growth occurs in the basement areas. (Call for estimate) The Inspector highly recommends that if the worms keep appearing after all the basement areas have been remediated and sealed, all water intrusion issues have been resolved, and the basement areas are properly dehumidified, the Client should consult a Pest Control Expert to resolve the worm infestation issues. This expert should also look into the bee/ wasps issues in the attic. The Inspector highly recommends that a new properly sized basement to 1st floor door be installed in existing frame (fit best effort) with a bottom rubber seal kit to prevent further air currents from entering the living spaces from the basement areas. Same for the kitchen entry door. If the current door cannot be made to hang plumb and level and thus seal correctly on its substandard framing, it should be removed and a complete new door/ light assembly should be properly installed plumb, level, and proven to seal out the weather when open and closed normally. Not being able to use this door is a fire safety hazard and the leakage causes moisture intrusion and increases energy costs year round. The Inspector highly recommends that a professional plumber be contacted to “once and for all”, fix the kitchen drain leaks and plumbing part fit issues so that no further water damages occur under and around the kitchen sink areas or any other plumbing fixtures in the Property including the fridge ice maker. At the same time, the master bathroom toilet should be pulled, old seal removed and discarded, the entire flange area should be inspected for mold/water damages, remediated as indicated, or if ok, cleaned with 91% Isopropyl Alcohol, then a new proper height toilet flange gasket should be installed to prevent any further water damages from occurring in this areas. Also, the washer/dryer assembly should be pulled out, all plumbing checked for leaks and cracks, and if not already there, burst proof stainless water feed hoses should be installed to prevent any future water issues especially since the water shut offs (if they exist) are not accessible and could not be shut off if a break in the hoses occurs. The Inspector highly recommends that the microwave exhaust fan be vented directly outside by way of framed over duct work that runs through the basement stairwell area and out the right wall. This would help with moisture/condensation issues seen on the window sashes during the winter months. Page 17 of 19 The Inspector highly recommends that if the bathroom exhaust vent fans are 110 cuft/min or better, they should be disassembled to the point that the fan and motor etc., can be HEPA brush vacuumed and lubed, and that this preventive maintenance be conducted on a yearly basis. If less than 110 cuft/min they should be replaced with larger, quieter, more efficient units. [New common building calculations say you should have 50 cuft/ min minimum for each bathroom appliance (sink/toilet/bidet), 100 cuft/min for each shower/tub, and 200 cuft/min for each Jacuzzi]. Use this method to size your new fans. In addition, the open air space between the bottom of the bathroom door and the floor should be at least 1 inch to provide air intake since the bathroom doors and windows are normally shut when the shower is operating and with no intake air you will get very little exhausting of the moisture which results in surface mold growing on the ceilings and walls above the shower even if the vent fans are properly sized. The Inspector recommends that the cat litter boxes and cats be removed from the basement area to determine if they are the only cause of the current urine like odors. The Inspector highly recommends that if no viable source of the high yeast levels is found in the Kitchen/Living Room areas, as soon as possible (with an air scrubber operating inside) invasive inspection should be conducted under all FLIR indicated possible high moisture areas on the exterior facing interior walls and interior ceiling areas. All salvageable and exposed structurally sound wood based materials inside and out should then have a minimum of a 2-step chemical remediation process conducted on them. [NOTE: Depending on what is uncovered during this gutting, the gutting process may have to continue to other adjacent areas inside and out till one has gone at least a foot beyond any visible damages in all directions. Unknown contingencies both in sqft size and conditions, until after gutting and properly chasing the exposed damages. Additional 2-step processes may be required to treat any affected, exposed, and accessible areas, all areas would require HEPA vacuuming, new commercial foil faced insulation would be used to fix wall and ceiling insulation issues and all areas needing new wall/ceiling materials would be finished with mold resistant sheet rock, primed, and painted with 2 coats of high quality interior/exterior semigloss or gloss white washable paint.] This will be done on a time, material, rental, actual costs contingency basis thus no estimate is included with this report. Payment will be expected weekly until all work completed. The Client is advised to wear a P100 rated filter on a full coverage mask, full coverage clothing, and eye protection anytime work is being performed inside the Property. The Client is advised to inform anyone hired to perform repairs inside the Property areas to follow the same safety precautions since the mold spore concentration and types present could cause serious health issues in persons sensitive to their presence.
