What to Expect in the Mold Remediation Process

As long as the contamination is confined to no more than 30 square feet*, the remediation process will proceed as follows. These guidelines are widely used in the construction industry and recommend different levels of mold remediation based on the square footage of the mold and whether or not the mold is located within the home’s HVAC system.

  • Address any the water/moisture problem. This will prevent new mold spores from growing.
  • Isolate the contaminated area. Close doors and windows between the contaminated area and other rooms. In addition, if more than 10 square feet are affected, cover all doorways/openings with 6 mil. polyethylene sheeting, using duct tape to seal seams.
  • Mist contaminated areas to minimize dust.
  • Remove materials. Remove all wet and mold-damaged porous materials in accordance with EPA guidelines. Non-porous and semi-porous materials (e.g. metals, glass, hard plastics, wood, and concrete) can often be cleaned and reused, but for most porous materials (e.g. fabrics, ceiling tiles, insulation, wallboard), removal and disposal is generally recommended since ensuring complete mold removal is nearly impossible.
  • Place materials in plastic bags. Discard all wet and moldy materials in 6+ mil. thick plastic bags, double-bagged and tied closed. Wipe bags with damp cloth and detergent solution before removing them from contamination area for regular trash disposal.
  • Clean all moldy non-porous materials and wood surfaces with a wire brush. Wipe the area with disposable wipes. Discard wipes in the same manner as wet/moldy materials (see above). Scrub all moldy surfaces with damp cloth and detergent solution until no mold remains. Rinse surfaces with clean water.
  • Clean the affected area and egress. For areas no larger than 10 square feet, clean with a damp cloth and/or mop with detergent solution. For contamination areas of 10-30 square feet, vacuum all surfaces with a HEPA vacuum first. Discard cloths/wipes as described in two previous bullets.
  • Visually inspect to ensure that all areas appear free of contamination and debris.
  • Dry cleaned materials and keep the area well-ventilated so that residual moisture evaporates. Raising the indoor air temperature or using fans and/or dehumidifiers may speed up the drying process.
  • Update the remediation plan if additional mold is discovered during the process.
  • Replace building materials that were removed and bring to an intact and finished condition. The use of new mold-prohibitive building materials should be considered.
  • Assess the effectiveness of the remediation via evaluation methods recommended by the EPA. These include visual inspection and follow-up visits to confirm that moisture issues have been remedied and that occupants who have reentered the home have no aggravated health complaints or other physical symptoms of mold exposure. In some cases, additional testing may be recommended.
