Steps 1-3: Build a Shortlist Worth Vetting
1. Write down what you actually want
One paragraph: what gets done, what materials you prefer, when you need it finished. Contractors cannot bid accurately on "I want the kitchen nicer," and vague scopes are where every dispute starts. If you cannot describe it clearly, you are not ready to get quotes.
2. Find 3 to 5 candidates the right way
Start with verified contractor directories, then ask neighbors who have had similar work done in the last two years. Cross-check Google and BBB reviews. And here is a hard rule: never hire anyone who knocks on your door unsolicited. Door-knockers are the number one source of contractor scams, full stop.
3. Read their reviews like a detective
You are looking for four things: a real website (not just a Facebook page), at least two years of review history, thoughtful responses to negative reviews, and photos of actual completed work. A contractor with 50 five-star reviews and zero responses to the two bad ones is hiding something. See our guide on reading contractor reviews like a pro.
Steps 4-6: Verify Before You Trust
4. Check the license yourself
Do not take their word for it. Use our state-by-state license lookup guide and confirm three things: the license is active, it covers the right type of work, and there are no disciplinary actions. Hiring unlicensed can void your homeowners insurance if something goes wrong.
5. Verify insurance directly with the insurer
You need two policies confirmed: general liability (at least $1M) and workers compensation. Here is the part most homeowners skip: get the certificate directly from the insurance company, not a photocopy the contractor hands you. Photocopies can be faked or expired. If an uninsured worker gets hurt on your property, the liability can land on you.
6. Search for complaints and lawsuits
Check your state attorney general's office, the BBB, and local court records. Perspective matters here: one complaint from five years ago is noise. Three complaints in eighteen months with the same theme is a pattern. Patterns are what you are looking for.
Steps 7-9: Evaluate the Bid Like a Pro
7. Get 3 or more detailed written quotes
Every quote should break out labor, materials with brand names, permits, and timeline separately. Request free quotes and lay them side by side. Here is what you are looking for: legitimate bids for the same scope cluster within 15 to 20 percent of each other. A bid 30 percent below the rest is not a deal. It is missing scope, cutting corners, or a scam.
8. Ask these 5 questions in the interview
- Who will actually be here every day, you or a subcontractor I have never met?
- When something unexpected comes up, how do change orders work and who approves the price?
- What is your current workload, and when can you realistically start my project?
- Do you pull the permits, or is that on me?
- What exactly does your warranty cover, and for how long?
Watch for vague answers on change orders and timelines. Those are the two places most contractor disputes begin.
9. Call 3 references with this exact script
First ask: "Would you hire them again?" Then the more revealing question: "What went wrong, and how did they handle it?" Every project has friction. You are not looking for perfection. You are evaluating whether they communicate honestly and fix problems, or disappear and argue.
Steps 10-12: Get It in Writing
10. Insist on a real contract
Non-negotiable items: full scope of work, specific materials with brands and model numbers, start and completion dates, payment schedule tied to milestones, warranty terms, who handles permits, daily cleanup expectations, and a termination clause. A handshake and a verbal promise are worth nothing. If it is not written down, it does not exist.
11. Tie every payment to completed work
The standard structure: 10 to 33 percent deposit, payments released at defined milestones (demolition complete, rough-in passed inspection, and so on), and 10 percent held back until the final walkthrough is done to your satisfaction. Never pay the full balance before the work is 100 percent complete. No exceptions.
12. Document everything from day one
Photograph the entire "before" state. Get every change order in writing with a price before the work happens, not after. Do a final walkthrough with a written punch list before releasing that last 10 percent. This paper trail is what protects you if anything goes sideways.
Four Instant Deal-Breakers
See our full guide on 7 signs of a contractor scam, but these four mean walk away immediately: demanding cash or full payment upfront, no verifiable license or insurance, pressuring you to "sign today," and a bid dramatically lower than everyone else's. Any one of these is enough. Do not talk yourself into ignoring them.
