Each business is scored on signals we can verify from public data: a live, secure (HTTPS) website, mobile-friendliness, a published phone number and website, and fit with the general contractors category. We do not collect or display customer reviews, and we do not accept payment for placement. Businesses can claim their listing to correct contact details, but the rank is fixed by the data. Owners can claim a listing for a Verified badge and a direct link; sponsors appear only in labeled blocks outside the numbered list. Neither changes rank. Sponsor this page.
Each listing is scored on public signals we can check ourselves: whether the website is live and secure (HTTPS), whether it works on a phone, whether a phone number and website are published, and how closely the business matches the general contractors category. We do not collect customer reviews, so no star ratings or review counts appear here, and no business pays for placement.
Use this list to shortlist two or three general contractors, then read their Google reviews yourself, confirm license and insurance, and get written estimates before committing. The score here is a filter, not a verdict.
Licensing in Massachusetts runs through the Massachusetts Office of Consumer Affairs and Business Regulation (Home Improvement Contractor registration) together with the Board of Building Regulations and Standards (Construction Supervisor License). Before hiring anyone in Cambridge, ask for both the HIC registration number and, for structural work, the CSL number, and verify each in the state's public lookup before signing; Massachusetts also runs a Guaranty Fund for HIC-registered work. Also confirm current liability insurance, and get the license number in writing on the estimate.
