Example Mold Remediation & Removal Report.

Note:  This is a recent whole house mold remediation report from our main office.  However, it is a good indication of the type of mold problems that arise in the Oakland area.

General Information

Furnace / HVAC

  • The property is heated primarily by electric wall heaters or radiant hydronic heating.
  • Homes that are not equipped with a forced air heating system 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 950 sq.ft.
  • The necessary flow rate to establish 0.35-0.7 ACH for this home is 44-88CFM

Kitchen:

  • No increased moisture content noted in tested building materials.
  • No significant visible mold growth observed.
  • No suspicious temperature differentials noted on inspection with FLI
  • Evidence of past water damage to shelf under kitchen sink.
  • Tenant reports mold growth around kitchen window.

  • Bathroom exhaust fan is old and likely inadequate.
  • RH: 46.4%     Temp: 70.4F     CO2 = 1922ppm     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 50CFM continuous flow, and for 60 minutes at 80CFM once motion-sensor has been activated.
  • Establish containment.
  • Install HEPA scrubber for negative pressurization throughout the duration of work.
  • Remove affected vanity.
  • Remove affected sheetrock, baseboard, and underlying insulation.
  • Clean/treat/encapsulate contaminated framing, sheathing, or subflooring.
  • Perform detailed HEPA vacuuming of the entire contained area.
  • Apply EPA-registered anti-microbial agents to the entire contained area via ultra-low volume fogger.
  • Install dehumidifier and air movers to dry affected building materials if necessary.
  • Perform final IAQ sampling.
