Our Mold Testing & Inspection Process in Laguna Niguel, CA
We follow a comprehensive, multi-step approach to make sure nothing is missed:
1. Visual Inspection
Our inspector performs a thorough visual assessment of your home, checking for water damage, staining, and signs of mold in common and hidden areas like attics, basements, crawl spaces, and HVAC systems.
