XP Inspection Services

XP Inspection Services holds a 5-star rating across 107 Google reviews, which matters in Renton where moisture problems are common. The city's 79% average relative humidity and 40 inches of annual rainfall create ideal conditions for mold growth, especially in homes built around 1989 (the local median). A reliable mold inspector becomes essential when you're dealing with a climate this damp and older housing stock. That consistent rating suggests homeowners in the area have found value in their work.

Before hiring any mold inspector in Washington State, confirm they hold the proper licensing. If remediation work is needed, the contractor must have a Department of Labor and Industries registration - you can verify this at lni.wa.gov. One important caveat: inspectors who also perform remediation work face a conflict of interest under industry standards, since they may recommend more extensive (and profitable) work than necessary. A standalone mold inspection in your region typically costs $200 to $600, so it's worth asking whether the inspector performs only inspections or also handles remediation.
