Mold Testing Projects in Everett
Project Type > Mold Testing for a Home in Everett
- Client has had multiple water intrusion incidents due to ground water intrusion. Property manager / landlord has supposedly not done the appropriate clean-up and client requested an inspection to determine what problems still remain.
- This single family residential property was built in 1969 and is 1248 ft².
- Indoor air quality testing revealed excessively high airborne mold counts inside the home.
- Numerous locations were noted where visible mold growth was still
ANALYSIS OF YOUR RESULTS:
- Extreme Amplification: Mold spores were detected at levels many times greater than the threshold, indicating a site of high mold amplification and growth. Please refer to the attached report for more detailed information.
The most likely contributor of the elevated mold spores is:
- Prior water intrusion not being properly dried and remediated.
- Numerous locations still remain with visible mold growth on the surface of the building materials.
- Due to the extremely elevated levels of airborne mold, the home is unfit for occupancy at this time. Immediate action is necessary to rectify the situation.
- Due to the elevated levels of mold spores, professional remediation is strongly recommended. This would include the operation of a commercial HEPA air scrubber. This will rapidly lower the indoor mold spore levels. Please contact Environix for pricing.
- It is strongly recommended to have all contents inside the home cleaned prior to removal from the building. Mold spores have settled on the surface of the indoor contents and therefore can be carried from a contaminated area into a clean area and potentially contaminate the new area.
- Removal of water damaged and mold contaminated materials are necessary to begin lowering the indoor spore count.
RELATIVE HUMIDITY & TEMPERATURE READINGS:
- Elevated moisture detected on the wall near the tub. This is the result of shower overspray or tub splashing.
- Grout and caulking is in good condition and shows no signs of recent water intrusion.
- Minimize shower overspray and splashing. Consider installing a splash guard.
LOCATION: Back Bedroom
- The room is equipped with double paned metal framed windows with current evidence of light condensation and moderate mold problems.
- The room is equipped with carpeting in dirty condition. Carpeting can hold mold spores for long periods of time, long after the original source of the mold growth has been removed.
- Keep contents and furniture a minimum of 2-3 inches away from exterior walls to help prevent mold growth on these surfaces.
- Consider replacing the carpets or having the carpets cleaned using a hot water extraction method. Ensure the carpets are able to dry very quickly. Environix can provide air movers or dehumidifiers to assist in fast carpet drying. Please contact your inspector for pricing.
- Note: Recommendations related to the elevated indoor air quality sample should also apply to this room due to the relatively close proximity of the rooms.
LOCATION: Front Bedroom
- Elevated moisture detected in the east wall. This is a direct result of the water intrusion incidents.
- Bottom 2 ft of sheetrock had been removed and replaced along the north wall: Current sheetrock appeared in good condition currently with no elevated moisture or visible mold growth.
- Evidence of water damage was noted along west wall.
- Visible mold growth was noted behind the hot water tank. Hot water tank did not appear to have been removed to dry / treat / remediate the area behind it.
- Carpet tac along west wall was noted as water damaged and stained.
- Floor crack was noted in the concrete. Client noted that water had entered home through this crack. At the time of inspection the floor crack had been sealed with silicone. Unfortunately, this typically is not sufficient to prevent further water intrusion as the hydrostatic pressure is significantly stronger than a silicone sealant can provide.
- Carpet was pulled back to reveal significant water stains on the backside of the carpeting: No visible mold was noted on the carpet at this time, but due to the nature of the water intrusion event, the carpet should have been pulled and replaced.
- Mold on closet contents due to humidity created by the water intrusion event. Mold growth on contents is a sign of extreme levels of indoor humidity and very likely indicates highly elevated levels of mold spores. This could cause adverse health reactions in sensitive individuals.
- Water damaged paper contents were noted on the window sill. The amount of water damage does not indicate damage from humidity but from the water intrusion.
- The room is equipped with double paned metal framed windows with current evidence of condensation and moderate mold problems.
- NOTE: ANSI/IICRC 500 and IICRC 520 reference guidelines for water damage and mold remediation indicates that any water intrusion that has gone unmitigated for more than 2 weeks shall be treated as Category III (Black water) contamination. All items affected by black water are to be physically removed and replaced.
- Remove all components contaminated. This includes the bottom two feet of sheetrock from the west and east walls.
- Remove hot water tank to remove and remediate the section of wall behind.
- Removal of carpet, carpet pad and damaged carpet tac strips.
- Elevated moisture detected in the wall near the shower. This is the result of splashing from the shower.
- Shower / tub sealant is in good condition and shows no signs of recent water intrusion.
- Minimize splashing during shower use. Consider installing a splash guard.
- Evidence of water damage is present in the wall between the kitchen and bedroom.
- Evidence of mold growth present on the kitchen wall. This is the result of the water intrusion that occurred in the bedroom. No elevated moisture levels were currently noted.
- Visible mold growth noted behind the cove base in the kitchen.
- The kitchen windows are double paned vinyl framed and have past evidence of light condensation problems.
- Due to the mold growth on the wall being caused by category III water, it is necessary to remove the bottom 2 feet of sheetrock in the areas affected by the moisture.
LOCATION: Living Room / Hall
- Water staining noted on carpet in the hall between bedrooms. No elevated moisture levels were currently noted.
- Carpet was noted as being very dirty: Dirty carpets can be a source of elevated allergens, dust and mold.
- Recommend removal and replacement of all carpets and carpet pad.
