Hawk Environmental Services

Hawk Environmental Services holds a 5-star rating across 90 Google reviews, which carries real weight in Seattle. The region's 79% average humidity and 37 inches of annual rainfall create ideal conditions for mold growth, and Seattle's median home built in 1968 may face particular vulnerability. A consistently high rating suggests the company has earned trust from local homeowners dealing with mold concerns in this climate-challenged market. A standalone mold inspection typically costs $200 to $600 in this area, so you'll want to understand pricing upfront.

Before hiring, confirm that Hawk Environmental Services holds a valid contractor registration with Washington State's Department of Labor and Industries - you can verify 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. Ask whether the inspector has financial ties to any remediation work, and consider getting a second opinion before committing to major treatment.
