Ceiling Mold Growth

Building Type: Residential Home

Primary Complaint: Ceiling Mold Growth

Project Number: 103016

Relevant Project Info:

General Information

  • The home owner is concerned about damage to sheetrock on the ceiling of his daughter’s bedroom, and the potential for mold growth in that area.
  • Care must be 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 fresh-air intake or upgrading mechanical exhaust ventilation to function on a continuous flow (the recommended units for this method is a Panasonic Whisper Green exhaust fan and will require at least 2 units).
  • The estimated square footage of this home is 1,900 sq.ft.
  • The necessary flow rate to establish 0.35-0.7 ACH for this home is 89-177CFM.

Furnace / HVAC

  • The home is equipped with a high-efficiency natural gas furnace.
  • Home owner has noted water leaking from the PVC exhaust tube.
  • Furnace filter is of average quality and was in need of cleaning at the time of inspection.

Recommendations

  • The leaking PVC tube should be fixed immediately by a licensed furnace technician.

Daughter’s Bedroom:

  • Slightly increased moisture content was noted in sheetrock around the damaged area.
  • No significant visible mold growth was observed at the time of inspection.
  • RH: 42.9%     Temp: 68.3F     CO2 = 644ppm     CO = 0ppm

Recommendations

  • Although there is no cause for professional mold remediation at this time, due to the age of the home sheetrock repairs may disturb lead paint and the EPA requires lead testing and/or lead-safe renovation procedures to be followed.

Attic:

  • Obvious roof leaks were noted in the attic.  To prevent further damage, it is necessary to hire a professional roofing contractor to resolve the leaks immediately.  Environix can provide the names of reputable contractors at the customer’s request.
  • Insufficient ridge area ventilation installed throughout attic.  This limits the exhaustion of humid air through the roof assembly.
  • Insufficient soffit ventilation throughout the attic.  Existing ventilation blocked by improperly installed insulation.  This limits the influx of fresh air through the soffit vents, leading to excess condensation and mold growth.  It is recommended that blocked soffit vents be cleared and all soffit venting be protected by the appropriate baffling.

    Proper ventilation is necessary to minimize condensation and subsequent mold growth.  All areas of elevated moisture or improper ventilation must be addressed to ensure the effectiveness of our process.  Current code calls for 1sqft of ventilation for every 300 square feet of attic space, distributed evenly between the ridge and soffit area.

  • The ceiling currently lacks proper air sealing, allowing excess moisture and heat to escape into the attic area.  This air leakage is a key cause of energy loss, attic condensation and mold growth.
  • The attic contains one or more large chases (areas of connectivity between inaccessible interior cavities and attic space).  It is necessary to seal these chases with the appropriate materials to provide a continuous air and thermal barrier.
  • The exhaust ducting from the bathroom fan, whole house fan and/or kitchen range exhaust hood is not appropriately venting to the exterior.  This condition allows warm moist air to flow into the attic and is likely a contributing factor in condensation.  It is necessary for all exhaust ducting to vent completely to the exterior through insulated ducting and be connected to a dedicated roof jack with appropriately sized collar.
  • Insulation is missing from around skylights and the walls to the closet containing the attic access.
  • Ceiling Mold Growth

    Kitchen:

    • Minor water damage noted to ceiling.
    • No increased moisture content noted in tested building materials.
    • No significant visible mold growth observed.

    Basement:

    • No exhaust fan located above laundry appliances.
    • Minor deformation noted in one area of basement ceiling, this appears to be at the location of a nailhead, likely causing minor condensation.  No increased moisture content or other signs of water damage could be identified in this area.
    • RH: 38.1%     Temp: 68.3F     CO2 = 644ppm     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 40CFM continuous flow, and for 60 minutes at 80CFM once motion-sensor has been activated.

    Master Bathroom:

    • Exhaust fan is old and likely inadequate for the size of the bathroom.
    • Deformation to the tiles shower surround was noted below the glass block window.
    • Due to recent shower usage and water present in shower stall moisture testing and FLIR inspection could not determine if water was present in the areas of deformed tile.

    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 40CFM continuous flow, and for 60 minutes at 80CFM once motion-sensor has been activated.
    • Removal of a few tiles will allow for inspection of the shroud and facilitate the final determination of water damage and necessity of mold remediation in the cavity.
