How ProFix verifies Washington pros

Every Washington contractor on this directory cleared two checks before being published: a phone number in E.164 format with a Washington-area area code, and a published street address. Beyond that we show what we can corroborate, and only where we can: a license number or state-board lookup when the record carries one — 14,467 Washington licenses confirmed active against the state board, and appearance across more than one independent public source. Where a listing shows none of those, that means we have not found them — never that the contractor lacks them. We do not run a star-rating system on these pages because we do not hold first-party review data for Washington. Read the full method on /methodology and our scoring rubric on /trust-score. Suggest a correction or flag a stale listing on /corrections.
