A Few Facts To Consider

  • Mold is present almost everywhere, indoors and outdoors.
  • Mold spores are microscopic and float along in the air and may enter your home through windows, doors, or AC/heating systems or even hitch a ride indoors on your clothing or a pet.
  • Mold spores thrive on moisture. Mold spores can quickly grow into colonies when exposed to water. These colonies may produce allergens and irritants.
  • Before mold remediation can begin, any sources of water or moisture must be addressed. Otherwise, the mold may return.
  • Mold often produces a strong, musty odor and can lead you to possible mold problem areas.
  • Even higher-than-normal indoor humidity can support mold growth. Keep indoor humidity below 45 percent.

In addition, moisture meter readings are taken on the walls, cabinets and other surfaces around all lavatories, showers, appliances, and any suspect areas.  

Air samples are collected and analyzed by an independent and licensed laboratory that identifies the quantity and species of mold spores. 

When a suspect wet or stained wall is present, a wall cavity air sample can be collected to evaluate the presence of mold growth inside the wall (typically we drill a single 3/8” diam hole).  

Surface sampling to identify the type of mold is available when necessary.

Clients should understand that problems can often be rectified with minimal effort and expense.
