Discovered mold behind our basement drywall. Catalyst contained it properly, did the remediation, and brought in a third party to verify it was clean. Professional from start to finish.

Mold Remediation — FAQ
Some mold species produce allergens and mycotoxins that can cause respiratory issues, especially for sensitive individuals. Even cosmetic mold should be addressed because the underlying moisture problem will continue to feed growth.
We perform a visual and moisture assessment. For clearance testing we coordinate with an independent industrial hygienist to maintain protocol integrity.
In most contained jobs you can remain in unaffected areas. For widespread Category 3 jobs we will discuss relocation options with you.
Most residential remediations are completed in 2–5 working days depending on the size of the impacted area and required reconstruction.
