5 Microns Inc. Asbestos, Mold, Drinking Water, Radon, Air Quality Testing Lab

With a 4.9-star rating across 136 Google reviews, 5 Microns Inc. has earned strong trust in Seattle, where the climate makes mold a genuine concern. The region's 79% average humidity and 37 inches of annual rainfall create ideal conditions for mold growth, especially in older homes like Seattle's median 1968-built stock. When you're deciding whether to call, that rating suggests homeowners have found the testing reliable and the team responsive to local conditions. A standalone mold inspection in this area typically costs $200-$600, so you'll want to get quotes from a few places to compare.

Before you hire, know that 5 Microns Inc. is listed as a mold inspector. Industry standards flag a potential conflict of interest when inspectors also perform remediation work, since they'd profit from finding problems. Washington State requires any mold remediation contractor to hold a contractor registration with the Department of Labor and Industries - verify this at lni.wa.gov before signing any remediation contract. Always ask whether the inspector performs remediation, and consider getting a second opinion if they do recommend major work.
