What this service involves
Mold Assessment & Inspection
A mold assessment typically starts with the building and water history, a visual inspection and moisture readings, adds air or surface sampling with lab analysis only where it answers a defined question, and ends with a written report.
Mold Remediation
Mold remediation typically includes containment suited to the job, HEPA air filtration, and cleaning or removal of affected materials. Where the job calls for a check of the finished work by someone else, it should be done by the original assessor or another independent professional, not the company that did the work.
