Mold and Buildings Don’t Mix

Introduction
Concern about indoor exposure to mold has been increasing as the public becomes aware that exposure to mold can cause a variety of health effects including allergic reactions.

Mold can be found anywhere.  Mold can grow on virtually any organic substance, as long as moisture and oxygen are present.  There are molds that grow on wood, paper, carpet, foods, and insulation. When excessive moisture accumulates in buildings or on building materials, mold growth will often occur, particularly if the moisture problem remains undiscovered or unaddressed.

There is a lack of agreement between researchers about what constitutes a “problem situation” and an overall lack of industry experience in interpreting microbiological laboratory data.  Therefore, it is critical that the indoor air consultant be able to combine experience and knowledge of microbiology to evaluate laboratory results of samples collected from interior locations.

Initial Evaluation
The initial evaluation of suspected mold problem requires a thorough review of the building, including the HVAC system, suspect leaks, building materials, landscaping, and suspected mold-impacted areas. It is important to have a good understanding of occupant health issues and symptoms.

A typical air sampling strategy includes an outside air sample, a non-complaint area sample, and a complaint area sample.  Air samples are analyzed for both viable fungi and total spores (non-viable).   Surface samples will help identify specific genera in mold reservoirs.

Data interpretation is complex and should only be done by trained professionals.

Mold Remediation
Every project is different, however, rapid response and repair of the water or humidity problem is critical.  Non-porous surfaces can be cleaned and disinfected. Porous materials contaminated with mold must be replaced.  Disinfection is not a substitute for removal of porous material as dead fungi remain allergenic and toxigenic.

Because of the health effects associated with elevated concentration of microorganisms, remediation should be performed only by competent individuals familiar with the precautionary measures required.

Post-Remediation
Royal Inspection recommends that post-remediation verification inspections be conducted.  A thorough visual inspection of the area is completed.  Surface and air sampling for microbial contaminants may be required to document proper clean-up.
