How to verify a home improvement contractor before hiring

A polished website or strong review score does not verify that a contractor is qualified for a specific project. Use the relevant state, county, or city authority to confirm licensing and discipline, ask the insurer to confirm coverage, compare written estimates, and put the complete scope, payment schedule, permits, changes, warranties, and completion terms in writing.

What matters first

  • Licensing rules vary by trade and location, so verify the exact business name, responsible person, classification, status, and jurisdiction for your project.
  • Insurance documents should be current and applicable to the work; ask how general liability and workers’ compensation apply rather than relying only on a logo or photocopy.
  • Large upfront demands, cash-only payment, pressure to decide immediately, offers to arrange unfamiliar financing, and requests that the homeowner pull contractor permits are warning signs.
  • Reviews can provide leads, but official license, court, consumer-protection, permit, and complaint records offer a stronger verification trail.

Verify before spending

  1. 1Find the contractor’s legal business name and license number, then confirm both directly with the applicable state or local licensing authority.
  2. 2Check state and local consumer-protection resources for complaint or enforcement information and search the business name with terms such as complaint, lawsuit, scam, and review.
  3. 3Obtain multiple written estimates that describe labor, materials, dates, allowances, exclusions, permits, cleanup, payment stages, and change-order procedures.
  4. 4Do not make final payment until the contracted work and agreed corrections are complete, required inspections have occurred, and you have the warranties, releases, and records your location requires.
