Before you hire anyone for mold remediation in Portland, make sure they hold a current CCB (Construction Contractors Board) license from Oregon - you can verify this at oregon.gov/ccb. It's also worth getting multiple quotes, since a typical project in this area runs between $1,500 and $4,500 depending on the scope. Finally, ask for references from recent jobs and check online reviews to see what other homeowners experienced. ServiceMaster of Portland is one option to consider, with a 4.7-star rating across 307 Google reviews.
Portland's climate - averaging 76% relative humidity and 36 inches of rain yearly - creates conditions where mold can develop quickly, especially in older homes like many built around 1971 throughout the area. When you contact ServiceMaster of Portland or any contractor, ask them to walk you through exactly what's included in their estimate and what happens after the work is done. Before signing any contract, confirm in writing what remediation methods they'll use and whether they offer any follow-up inspection or guarantee.
