Mold Investigation

Visual Inspection
A visual inspection is the initial step in identifying possible contamination problems. It will identify any visible water leaks or moisture stains on ceilings, walls, floors or under counters. The air conditioning systems and eating systems, the attic, and crawl spaces under homes will receive a visual inspection as well. Equipment such as a moisture meter is used to help identify hidden sources of mold growth and the extent of the water damage. Mold sampling will be recommended if there is any noticeable mold growth, musty odors, visible water damage or stains, poorly maintained HVAC systems or construction defects. By combining a visual inspection with air, tape or swab sampling, the Inspector can help identify the hidden source of mold, allergens and indoor pollutants and the extent of any acute or chronic water or moisture damage.

Air Sampling
The purpose of air sampling is to determine the type and amount of airborne contamination in the building. Air sampling may be necessary if the presence of mold, allergens, or toxins is suspected (e.g. musty odors, allergies) but cannot be identified by a visual inspection. When air sampling is performed, both the indoor air and outdoor air are sampled, so the results can be compared to determine if a problem exists. Typically, the indoor sample is taken while the heating and/or air conditioning unit is operating; this will insure that the interior air is effectively tested.

Tape/Swab Sampling
Tape or Swab samples are usually collected from visible moldy surfaces by wiping the area with a sterile swab. This type of sampling is used to identify specific mold types.

Laboratory Results and Recommendations
Once the home has a visual inspection and the mold circumstance has been evaluated, action can be planned to clean it up and prevent future contamination. Based on the site evaluations and sampling lab analysis results, your inspector can provide a detailed written report that can be used for disclosure and references. In all situations, if mold exists, the underlying cause of the water damage must be corrected.

Reducing or Eliminating Mold
It is impossible to completely eliminate all mold and mold spores indoors. Mold will always be found floating in the air and in house dust. Indoor mold growth can be prevented by controlling water and moisture indoors. The following are steps to prevent or reduce mold growth:

• Repair any water leaks
• Provide good air circulation
• Install a good electrostatic filter on the HVAC system return
• Use bathroom, kitchen and laundry room exhaust fans that exhaust to the exterior
• Insulate, and properly ventilate attic and crawl space areas
• Clean, dry or remove items that are damaged by water immediately

If the contaminated area involved is large, you may wish to consider hiring a professional remediation company.

Post Remediation Testing
The most important part of the remediation (Clean Up) process is the post remediation testing. This final testing procedure provides confirmation that the project has been satisfactory in remediation the mold contamination and that the contamination has not spread to other areas.
