“Verified” covers: verified operating (open in current business listings), verified business information (name, address and phone match those listings) and, where shown, a verified business record (state license or registration). Checks show what public records and documents said on the date shown; they are not a guarantee of work quality. Insurance is a document the business sent us.

What the checks mean

Each row is one public record or document, with its source and date. Checks don’t rate the work: compare quotes for that.
