Mould growth often follows water damage that was not dried quickly or completely. It can develop behind drywall, under flooring, in attics and in basements. Disturbing it without precautions can release spores into the air and spread contamination to other parts of the building, which is why remediation follows a careful process.
Our mold removal and remediation service in Richmond Hill uses containment to isolate the work area, removes affected porous materials, cleans remaining surfaces and uses HEPA filtration to help capture airborne particles. Just as importantly, we work to identify and address the moisture conditions that allowed growth, so remediation is not simply undone by the next leak or humid season.

How this service works
Remediation typically includes setting up plastic containment, using negative air pressure where appropriate, removing mould-affected drywall, insulation and other porous materials, HEPA vacuuming, cleaning framing and other surfaces, and drying. The scope depends on the size of the affected area and the materials involved.
