Alpha Environmental Services holds a 4.8-star rating across 524 Google reviews, which matters in Portland where high humidity (76% average) and 36 inches of annual rainfall create ideal conditions for mold growth. Many of the area's homes were built around 1971, and older construction is especially vulnerable to moisture problems. That track record suggests the company knows how to handle the specific challenges Portland homeowners face.
Before hiring, confirm that Alpha Environmental Services holds a current Oregon Construction Contractors Board (CCB) license by checking oregon.gov/ccb. Mold remediation contractors in Oregon are required to be licensed, so this step protects you. Typical remediation projects in this area run between $1,500 and $4,500, so get a detailed estimate upfront and verify the scope of work before any contract is signed.
