3 Common Mold Cleanup Methods

mold cleanupWhile the location and type of mold growth varies inside houses, mold cleanup methods are generally consistent. After taking air samples and tracking down and testing active mold growth, the location, type of mold and extent of contamination are verified. This provides mold remediation professionals with a starting point to eliminate mold and restore a healthy indoor environment. Here are three common methods that will be utilized.

  • Eliminate the moisture first. As long as recurrent moisture is present, active mold will resist cleanup efforts. Therefore, the source of water that triggered mold growth must be identified and permanently eliminated and affected areas of the house dried to industry standards. In addition to the primary water source, steps must be taken to control secondary effects such as high indoor humidity and dampness that also support mold growth.
  • Mold removal and surface treatment. All active mold must be removed from the house. On smooth hard surfaces, mold growth may be wiped away and EPA-approved fungicides used to sterilize the surface. On porous materials such as wooden building materials and drywall, long-term mold growth may penetrate below the surface. Effective treatment requires physically cutting out the affected segment and replacing with new material. Contaminated carpeting may be spot-treated with fungicides in very limited areas. Widespread contamination usually involves the padding beneath, as well, and requires removal and disposal of both carpet and padding, then decontamination of the floor before installing new carpet.
  • Cleaning up the air. Microscopic airborne mold spores circulate in the air and settle on surfaces throughout the home. Residual spores can trigger a recurrence of mold growth after cleanup. Therefore, the house should be thoroughly vacuumed with HEPA-filtered equipment capable of retaining spores to prevent airborne spread. Also, filters in the HVAC system should be discarded and high-quality replacements installed. In cases of high levels of airborne spore concentration, HVAC coils and ductwork may require decontamination.
