TradeScore ratings are generated algorithmically from publicly available data including California CSLB license records, Better Business Bureau filings, Google Business Profile data, and automated website analysis. Scores reflect the data available at the time of scoring (see date above) and are updated periodically. Scores are informational tools designed to help homeowners research contractors. They are not endorsements, guarantees of work quality, or recommendations to hire or avoid any contractor. Data accuracy depends on public sources and may not reflect recent changes.
