Plumbline
Free, neutral public-record information about any contractor: license, status, and what the record says, with the source for every fact. Built for homeowners and their AI agents. We never take money from contractors and never sell leads.
We look up a contractor's public license record. Not a rating or a background check.
Coverage
Jurisdictions marked "partial coverage" are still being indexed: a "no records found" there means very little yet. Use the official board lookup to be sure.
