How ProFix verifies Maryland pros

Every Maryland contractor on this directory had to clear four independent checks before being published: a verified phone in E.164 format with a Maryland-area area code, a published street address, a license number or state-board verification URL on file, and appearance across at least two independent public sources. We do not run a star-rating system on these pages because we do not yet hold first-party review data for Maryland — only signals we can independently corroborate from the state's own published rosters and permit feeds. Read the full method on /methodology and our scoring rubric on /trust-score. Suggest a correction or flag a stale listing on /corrections.
