Alpha Environmental Services holds a 4.8-star rating across 524 Google reviews. If you're dealing with mold in Portland, you're not alone - the city's 76% average humidity and 36 inches of annual rain create ideal conditions for it to grow. Older homes are especially vulnerable, and since the median Portland house was built in 1971, many residents face this problem. The good news is that professional remediation is available and typically costs between $1,500 and $4,500 in this area.
Before you call anyone, make sure they're properly licensed. Oregon requires mold remediation contractors to hold a CCB (Construction Contractors Board) license, and you can verify this yourself at oregon.gov/ccb. This step takes five minutes and protects you from unlicensed operators. When you contact Alpha Environmental Services, ask them directly for their CCB license number and confirm it matches what you find online.
