How to Check a Home Contractor’s Credentials

Verify licensing and registration

Licensing requirements vary by state and locality and may differ by trade. Ask for the contractor’s legal business name, license number, and the trade classifications that cover the work, then confirm active status and any public disciplinary information with the issuing authority.

Use official state or local resources rather than relying on a badge, directory listing, or a contractor’s link alone. If the authority’s records are unclear, contact the licensing office and ask what the credential permits the contractor to do.

• Confirm the name on the contract matches the licensed business.
• Ask whether required subcontractors hold their own applicable credentials.

Confirm insurance and responsibility

Request current proof of liability insurance and, where applicable, workers’ compensation coverage. Contact the insurer or agent using independently verified contact details if you need to confirm that a certificate is current and applicable.

Ask who is responsible for subcontractors, property protection, cleanup, and damage discovered during the work. Clarify whether the contractor will obtain permits and arrange inspections.

Check references and business practices

Request references for projects similar in scope and age of home, then ask the homeowners about communication, schedule, cleanup, change handling, and follow-through after completion. A reference is useful context, not a substitute for licensing and contract review.

Compare the written contract, warranty, payment schedule, and cancellation terms. Be cautious about pressure to sign immediately, vague company identity, or requests for payment that do not correspond to documented work and materials.
