Basis (estimate): Estimate only: manually checking a license board, reading reviews across sites, and dissecting a quote takes an evening; no timed study found.
What does this setup do?
Vet a home contractor’s license, insurance, reviews, and quote for red flags before you sign a contract or pay a deposit.
Who is it for?
Homeowners getting bids for roofing, remodeling, or repairs who do not want to learn about contractor fraud the hard way.
How do you set it up?
Tools
- ChatGPT, Claude, or Perplexity (Perplexity can check current license board and review pages)
- Contractor name, business name, and license number
- The written quote or estimate
- Your state’s contractor license board website
Steps
- Get the contractor’s full business name, license number, and a written quote. No quote, no hire.
- Look up the license yourself on your state’s contractor board site. Confirm it is active and matches the business name.
- Ask the AI to build a vetting checklist for your state and project type: license, insurance, bond, reviews, references.
- Paste the quote in and ask the AI to flag vague line items, missing materials, and payment terms that favor the contractor.
- Ask the AI to draft reference-check questions and red-flag questions for the final interview.
- Call two references yourself and ask about communication, timeline, and surprise charges.
- Never pay a large deposit up front. Progress payments tied to completed work protect you.
Example output
Illustrative. Your results will differ.
- Your contract and the request, side by side
- 3 clauses that don't match, flagged in plain words
- You decide what to push back on.

What usually goes wrong?
Where agents tend to stall on this job. More patterns in Where AI gets stuck.
- The AI may describe licensing rules for the wrong state. Always confirm on your own state board site.
- AI-drafted contracts are a starting point, not legal advice. For big jobs, have a real person review the contract.
- A contractor with no online presence is not automatically a scam, but it means your reference calls matter more.

Common questions
- How much deposit is reasonable?
- As little as possible. Progress payments tied to completed milestones protect you. Big upfront deposits are the classic setup for a disappearing contractor.
- What if the contractor is not licensed?
- Some states do not license every trade, but then insurance and references matter even more. The AI checklist will adjust for your state if you tell it which one.
- Can the AI check reviews for me?
- An AI with web search can summarize what review sites say, but read a sample of the actual reviews yourself. Tone and detail tell you things a summary cannot.
What tips make it smoother?
- Verify the license yourself on the state board site. The AI cannot do the lookup for you in most states, and a screenshot of a license means nothing.
- Ask for a certificate of insurance and call the insurer to confirm it is active. Policies lapse.
- Get three written quotes. One quote tells you nothing about whether the price is fair.
- Check reviews on more than one site. Fake reviews exist, and patterns across Google, BBB, and Yelp are harder to fake.
