Questions to Ask a Contractor About Their Insurance Policy

Ask these questions before you sign:

  • Who is the insurance carrier, and what is the policy number?
  • When does the policy start and end?
  • Are subcontractors covered, and do they carry their own insurance?
  • Will you list me as an additional insured?

Clear answers are a good sign. If you are also considering a gate, explore custom automated and security gate installation and its licensing and insurance details. Vague answers are a reason to pause and verify further.

Use these questions to check a contractor’s coverage before you sign, and compare the answers against what you have been shown.

Frequently Asked Questions

How can I verify a contractor’s insurance coverage?

Ask the contractor for a current certificate of insurance, then confirm it directly with the insurance agent or carrier named on the document. Check that the policy number, effective dates, and coverage types match what the contractor described. Calling the agent is the most reliable check because a certificate can be altered or outdated. If the contractor will not provide a certificate or refuses to let you contact the insurer, treat that as a warning sign and consider hiring someone else.

What questions should I ask a contractor about their insurance policy?

Ask for the legal business name on the policy, the carrier name, the policy number, and the expiration date. Find out whether general liability and workers’ compensation are both active and what the coverage limits are. Ask whether your home would be listed as the certificate holder or additional insured for your project. Also ask whether subcontractors working on your property carry their own insurance, since gaps there can become your problem.

How do I check if a contractor is licensed and insured?

Start by asking for the contractor’s license number and insurance details in writing. Look up the license with your state or county licensing board, which typically lists the license status and any complaints. Then verify the insurance by contacting the carrier listed on the certificate. Matching names, license status, and active coverage dates across all three sources gives you a reliable picture before any work begins.
