Environix

Environix holds a 4.9-star rating across 398 Google reviews, which carries real weight in Seattle's climate. With 79% average humidity and 37 inches of annual rainfall, moisture problems are common here, and many homes date back to 1968 or earlier - structures that can be especially vulnerable to mold. A strong local rating suggests the company has handled the specific conditions homeowners face in this region. A standalone mold inspection typically costs $200-$600, so you'll want to understand what you're paying for before calling.

Before hiring Environix, verify their licensing status. Washington State requires mold remediation contractors to hold a contractor registration with the Department of Labor and Industries, and you can confirm this at lni.wa.gov. One important caveat: inspectors who also perform remediation work can face a conflict of interest under industry standards, since the same company profits from finding problems and then fixing them. Make sure you understand whether Environix performs both services and how that may affect the independence of their inspection.
