Example Inspection Report for Mold in Renton, Wa

Date of Inspection: July 11th, 2011

General Information

  • Home owners are concerned about mold growth on walls and ceiling.
  • The windows in the home are in very poor condition, several of the windows are not operable.  The home owners are planning to replace the windows with modern energy-efficient units.  It is vital that the ventilation in the home be addressed prior to the installation of new windows.  When the new windows are installed it will decrease the natural building leakage significantly, without the recommended improvements to ventilation the building will likely suffer from high humidity and a significant decrease in indoor air quality.

Furnace / HVAC

  • Homes must have special care taken to ensure appropriate ventilation, and prevent the buildup of humidity and other pollutants.
  • Current standards recommend 0.35 to 0.7 air changes per hour, this may be attained by installation of a ducted heat recovery ventilator or upgrading mechanical exhaust ventilation to function on a continuous flow (the recommended units for this method is a Panasonic Whisper Green exhaust fan).
  • The estimated square footage of this home is 1,370 sq.ft.
  • The necessary flow rate to establish 0.35-0.7 ACH for this home is 64-128CFM.         

Kitchen:

  • No obvious plumbing leaks noted.
  • No increased moisture content noted in tested building materials.
  • Kitchen range exhaust hood has been removed.
  • No increased moisture content noted in tested building materials.
  • No significant visible mold growth observed.
  • No suspicious temperature differentials noted on inspection with FLIR.
  • No obvious signs of water damage.
  • RH: 60.1%     Temp: 69.4F     CO2 = 624ppm     CO = 0ppm

Recommendations

  • Install kitchen range exhaust hood to adequately exhaust humidity generated by cooking.

Laundry:

  • No exhaust fan located in this area.
  • Large areas of painted walls are flaked and peeling.
  • Plywood flooring is not level.
  • Sheetrock missing from area below electrical panel.
  • No increased moisture content noted in tested building materials.
  • No significant visible mold growth observed.
  • No suspicious temperature differentials noted on inspection with FLIR.
  • No obvious signs of water damage.
  • RH: 54.4%     Temp: 71.5F     CO2 = 690ppm     CO = 0ppm

Recommendations

  • The exhaust ventilation in this area is inadequate, it is recommended that a Panasonic Whisper Green 80CFM exhaust fan be installed and set to run at 30CFM continuous flow, and for 60 minutes at 80CFM once motion-sensor has been activated.
  • The home owner reports that repair to the flooring and sheetrock will be taking place.  Once the sheetrock and new insulation have been installed the area will be more energy efficient, but at this time the existing conditions do not appear to be having a negative impact on indoor air quality.

Master Bedroom:

  • Staining on sheetrock around the nail heads was visible in several areas of the bedroom; this condition is likely secondary to condensation in these areas due to poor ventilation.
  • Old roof leak was noted in the closet; this area does not appear to have any continuing issues and can be repaired cosmetically.
  • Windows in poor condition.
  • Sections of sheetrock and insulation have been removed from the closet.
  • Evidence of high humidity was noted due to water staining on the window sills.
  • No increased moisture content noted in tested building materials.
  • No significant visible mold growth observed.
  • No suspicious temperature differentials noted on inspection with FLIR.
  • No obvious signs of water damage.
  • RH: 54.7%     Temp: 72.0F     CO2 = 660ppm     CO = 0ppm

Recommendations

  • Install insulation and sheetrock as per normal construction techniques, where necessary.

Hall Bathroom:

  • Moderate surface mold growth noted on ceiling and exterior wall.
  • No bathroom exhaust fan installed.
  • Minor sized area of increased moisture content noted in vinyl flooring around toilet supply line.
  • Tub is claw-foot with circular curtain, this condition often causes water to be splashed on floor or walls.  The home owners are very diligent about keeping the water from wetting building materials and no damage or issues were noted.
  • RH: 54.5%     Temp: 73.4F     CO2 = 802ppm     CO = 0ppm

Recommendations

  • Moderate surface growth was noted in this area, at this time the there is no reason to suspect that the underlying building materials have been affected.  Professional remediation is not necessary and the client may clean the area with standard surfactants and/or EPA-registered anti-microbial agents.  Once the area is cleaned it may be painted or repaired as needed.
  • The exhaust ventilation in this area is inadequate, it is recommended that a Panasonic Whisper Green 80CFM exhaust fan be installed and set to run at 40CFM continuous flow, and for 60 minutes at 80CFM once motion-sensor has been activated.

Guest Bedroom:

  • This room is used for indoor plant growth.
  • Window is not functional.
  • Large hole around sewer vent stack leading to both attic and crawlspace.
  • No increased moisture content noted in tested building materials.
  • No significant visible mold growth observed.
  • No suspicious temperature differentials noted on inspection with FLIR.
  • No obvious signs of water damage.
  • RH: 58.6%     Temp: 72.1F     CO2 = 1015ppm     CO = 0ppm

Recommendations

  • Seal holes in ceiling and flooring in closet to prevent infiltration of crawlspace or attic air into the living space.
  • Provide Environix with environmental conditions desired to adequate grow indoor plants (temperature and humidity).  Based on the desired conditions, Environix can then generate a plan to maintain these variables without causing damage or inappropriate levels of humidity in the remainder of the home.  This plan will likely include exhaust ventilation and moisture barriers.

Living Room:

  • Increased moisture content noted in window sill area.
  • Window sill near door swollen and deformed.
  • Increased moisture content noted in siding associated with window nearest door.
  • Gutter appears to be improperly graded towards affected window area.
  • RH: 46.8%     Temp: 74.9F     CO2 = 760ppm     CO = 0ppm

Recommendations

  • The results of the indoor air quality samples do not reveal elevated mold spore levels in this area, but the water intrusion must be addressed to prevent further damage.  When windows are replaced the extent of damage to the framing and sheetrock can be easily assessed, if significant mold growth is found a plan for proper remediation can be established.
  • Hire an appropriate contractor to assess the gutters and roof at the area of leak to stop future water intrusion and replace any sections of damaged siding or trim from the exterior.   By performing as much water damage restoration work as possible from the exterior, it will limit the likelihood of contamination to the living space.

Office:

  • History of mold growth above window.
  • No increased moisture content noted in tested building materials.
  • No significant visible mold growth observed.
  • No suspicious temperature differentials noted on inspection with FLIR.
  • No obvious signs of water damage.
  • RH: 49.3%     Temp: 74.2F     CO2 = 747ppm     CO = 0ppm

Recommendations

  • Mold growth in this area was likely secondary to condensation from poor ventilation, as no increased moisture content or signs of water damage were noted in this area.

Dining Room:

  • Obvious past water damage above window.
  • Cracks in sheetrock below window.
  • No increased moisture content noted in tested building materials.
  • No significant visible mold growth observed.
  • No suspicious temperature differentials noted on inspection with FLIR.
  • RH: 49.6%     Temp: 74.6F     CO2 = 781ppm     CO = 0ppm

Recommendations

  • The results of the indoor air quality samples do not reveal elevated mold spore levels in this area, but the water intrusion must be addressed to prevent further damage.  When windows are replaced the extent of damage to the framing and sheetrock can be easily assessed, if significant mold growth is found a plan for proper remediation can be established.

Crawlspace:

  • Recent duct repair had been performed in this area.
  • One section of the HVAC plenum had become disconnected, allowing crawlspace air to directly enter the HVAC system.
  • The ducting had not been appropriately sealed with duct sealant.

Recommendations

  • Call original contractor and request that the plenum be appropriately sealed and all HVAC duct joints be sealed with high-velocity duct sealant (mastic).
  • Environix can provide confirmation that HVAC work had been completed as requested if photos and a written report are supplied.
