How to avoid contractor scams: what to know before you hire again
You already know what it feels like. You hired someone who seemed legitimate. Maybe they had reviews, a decent website, and said all the right things. And then — the work stalled, the calls stopped, the money was gone, or what got built fell apart within months.
You're not alone, and this wasn't your fault for trusting someone. The FTC received more than 81,000 reports of home improvement fraud in 2024. That's 81,000 homeowners who did what seemed reasonable and still got burned.
If you've been through it, this post is for you. We're going to break down what probably happened, why it worked, and what to do differently next time.
Why contractor scams are so hard to spot in advance
Contractor fraud doesn't look like fraud at first. That's the whole point. The people who are best at it show up with a clean truck, a website, a few reviews, and a firm handshake. You don't see the warning signs until the money is gone and the work has started (or hasn't).
Home improvement is uniquely easy to exploit. The upfront costs are large. The work happens inside your home, so walking away mid-project is a nightmare. Licensing and insurance verification is harder than it should be. And most homeowners only hire contractors a few times in their life, which means you have almost no reference point for what “normal” even looks like.
The best thing you can do is learn the patterns.
The scams happening right now
The Lowball and Explode
A contractor quotes a price that seems almost too good. You hire them. Work begins. Then come the change orders. Unforeseen issues. Additional materials. Complications that “couldn't have been anticipated.” By the time the project wraps (if it ever does), the final bill is way higher than what you signed for.
It works because once your walls are open or your roof is half-replaced, what are you going to do? Fire them and find someone willing to finish a stranger's half-done job? That's expensive, complicated, and the contractor knows it.
The tell:The original quote was vague. No itemized materials, no breakdown of labor, no specifics on what was and wasn't included. Scope ambiguity is how change orders get manufactured.
The Large Deposit Disappearance
A contractor asks for a big upfront payment. Sometimes they say it's for materials. Sometimes they just call it standard practice. You pay. Then the work either never starts, starts and stalls, or barely progresses before they ask for another check. Then they stop returning your calls.
This is contractor fraud in its simplest form, and it's the most common. Too much money before too much work creates exactly the wrong incentives. Once a contractor has been paid in full, or close to it, there's no financial reason for them to stay on schedule.
How to spot it:They want more than 20–30% before any work has started. Good contractors tie payments to milestones. Real work completed, not promises made.
The License Laundering Scheme
A contractor shows you a license. It's real. But it belongs to someone else, or it covers a different type of work than what you're hiring for. The actual job gets done by unlicensed workers operating under a credential that doesn't apply to them.
Two problems here. Unlicensed work is more likely to fail inspections, create safety hazards, and cost you real money to fix. And when something goes wrong, there's no licensed professional on the hook. You're stuck with the problem and a contract that won't help you.
What to watch for:The license number is on the paperwork, but you never looked it up yourself on your state's contractor licensing board. Seeing a license and verifying it are two different things.
The Storm Chaser
After a big storm, hail damage, or hurricane, contractors show up at your door offering fast roof repairs at a discount. The pitch is always urgent: your neighbors are already doing it, insurance will cover it, you need to move now before things get worse.
Some take a deposit and vanish. Others do the work with cheap materials that fail within a year. Post-disaster urgency plus unsolicited door-knocking is one of the oldest fraud setups in the business.
The tell:You didn't seek them out. They found you. Good contractors don't need to canvass neighborhoods after storms. They have enough work from referrals.
The Scope Creep Spiral
You hire someone for a small job. Once they're inside your house, they start finding “urgent” problems. A cracked joist. A pipe that's about to fail. Electrical work that's “not up to code.” Every issue needs to be fixed right now, and they need a decision before they leave.
Sometimes these discoveries are real. Often they're not. What you're looking for is a pattern: an escalating series of problems, all requiring immediate cash decisions, all happening while you feel like you can't say no because your house is at stake.
The tell: The contractor is making urgent recommendations about work outside the original scope before the original scope is even finished, and every recommendation requires immediate payment.
What a legitimate contractor actually looks like
It helps to know what you're comparing against. Here's what a professional contractor who isn't going to screw you over generally looks like:
They put everything in writing. Real contracts with scope of work, materials listed by brand and spec, a timeline, payment milestones, and change order procedures. Not a paragraph on a napkin. If the contract is vague, that vagueness benefits them, not you.
They give you credentials you can actually verify. A license number you can look up on your state's licensing board. A certificate of insurance showing general liability and workers' comp. Not “yeah, we're insured” over the phone.
They don't mind if you get other bids. In fact, they expect it. A contractor who pressures you to sign before talking to anyone else doesn't want you to have a frame of reference. Pros are confident in their pricing because they know what they're delivering.
Payments follow the work. A 10–20% deposit at signing is normal. After that, you pay as milestones get hit: small payments at the start, bigger ones as labor and materials ramp up, and a final payment when you're satisfied with the finished work.
They pull permits. A contractor who says skipping permits will save you money is either cutting corners or dodging inspections. Unpermitted work becomes your problem when you sell, and it means nobody ever checked if the work was done right.
They don't get weird when you ask questions. If verifying a license or requesting references makes someone defensive, that tells you something. A good contractor has heard these questions a hundred times and doesn't flinch.
The verification steps most homeowners skip
None of this takes long. Maybe 30 minutes total. And it catches most bad actors before any money changes hands.
Look up the license yourself.Every state has an online contractor license lookup. Google your state name plus “contractor license lookup.” Enter the license number from the contract, not just the name. Make sure it's active, it's registered to the person you're actually hiring, and it covers the type of work being done.
Get a certificate of insurance sent to you.Ask the contractor to have their insurance company send it directly. That's how you know coverage is real and current. A photo of a card or someone saying “yeah, we're covered” doesn't cut it.
Look beyond Google reviews.Check your state attorney general's consumer complaint database, the BBB, and your licensing board's disciplinary records. Five-star reviews and a stack of complaints can absolutely coexist. Scammers know how reviews work.
Call a reference they didn't hand-pick. Find a reviewer on Google or Yelp who had a project similar to yours and reach out. Ask how the contractor handled something that went wrong. Every job has problems. What matters is how they deal with them.
Google their name with “complaint,” “fraud,” and “lawsuit.”Two minutes. A contractor who's been sued repeatedly for the same thing you're about to hire them for will often show up in local news or court records.
If you've already been burned: what to do next
If a contractor took your money and disappeared, did work that's already falling apart, or walked off the job halfway through, you have more options than you probably think.
Start by documenting everything. Photos of the current state of the work, copies of all contracts and receipts, screenshots of every text and email. Do it now, while it's fresh.
File a complaint with your state contractor licensing board. This triggers an actual investigation and can get their license pulled. It also creates a public record that warns other homeowners.
File a federal complaint at ReportFraud.ftc.gov too. The FTC uses these to build cases when multiple people report the same bad actor.
Call your state attorney general's consumer protection office. A lot of states have home improvement fraud laws that allow for double or triple damages plus attorney fees. This is often the fastest route to real consequences.
Talk to a consumer protection attorney. Many take contractor fraud cases on contingency, so the initial conversation costs you nothing.
If you paid by credit card, dispute the charge. Chargebacks aren't guaranteed, but for deposits on work that never happened, they're absolutely worth trying.
How to hire differently this time
The homeowners who get burned twice are usually the ones who chalk the first time up to bad luck. Bad luck happens, sure. But most contractor fraud follows patterns that a better process would have caught. We cover the most common warning signs in our red flags guide for contractor quotes.
Before your next project:
Get at least three bids from licensed contractors. Not to find the cheapest one. To establish what the job actually costs. Our home improvement cost guide has real pricing ranges for every major project type. One bid tells you nothing. Three bids tell you whether a number is reasonable or suspicious.
Read the contract before you sign it. If it's one page with no line items, ask for more detail. If they won't provide it, walk.
Pay by credit card or check. Never cash. A contractor who wants cash is telling you they operate off the books.
Hold back 10% until the job is done and you're happy with it. A contractor who won't agree to that is telling you something about how confident they are in their own work.
Quotsey was built specifically for this problem. Every contractor on the platform is verified for licensing, insurance, and review history before they can receive project bids. If you're ready to hire again, sign up at app.quotsey.com and post your project to receive bids from vetted local contractors — or visit quotsey.com to learn more about how the platform works.
Frequently asked questions
What should I do if a contractor took my deposit and disappeared?
Document everything. Then file complaints with your state contractor licensing board, your state attorney general's consumer protection office, and the FTC at ReportFraud.ftc.gov. If you paid by credit card, start a chargeback with your card issuer. And talk to a consumer protection attorney. Many states have fraud statutes that allow for double or triple damages.
How much deposit is normal for a contractor?
10–20% at contract signing is normal for most residential projects. If there are big custom material orders, a higher deposit can make sense, but anything beyond that should be tied to actual milestones, not the calendar. If someone wants 50% or more before they've swung a hammer, that's a serious red flag.
How do I verify a contractor's license?
Google your state name plus “contractor license lookup.” Every state has a portal. Enter the license number exactly as it appears on their paperwork. Check that it's active, that it's registered to the person you're hiring (not someone else), and that it covers the type of work you need done. Five minutes.
Is it safe to hire a contractor who came door-to-door?
Probably not, unless you do a lot of extra homework. Door-to-door solicitation after storms is one of the most common fraud setups. If you're interested, take their card, don't agree to anything on the spot, look up their license yourself, and get competing bids before making any decisions.
What if I signed a contract but haven't paid yet and want to back out?
If you signed it in your home, the FTC's three-day “cooling-off” rule gives you 72 hours to cancel without penalty. Some states give you even longer. Cancel in writing (email or letter) within the window, and keep a copy.
How can I find a trustworthy contractor?
Start with referrals from neighbors or friends who have had similar work done recently. Verify licensing and insurance independently. Get at least three bids. Read reviews with attention to how the contractor handled problems, not just the star rating. And use Quotsey — where every contractor is pre-verified before they can access project leads.
The bottom line
Getting scammed by a contractor doesn't mean you were careless. You trusted someone who went out of their way to seem trustworthy. That's not a character flaw. It's what happens when one side of a transaction knows a lot more than the other.
Next time, that imbalance works in your favor. You know the playbook now. You know what to check. You know what a real contractor looks like before you sign anything, and you know what the warning signs look like before the money is gone.
Quotsey exists to make the verification step easier. Every contractor on the platform has been checked for licensing, insurance, and reviews before they can receive a single project lead. When you're ready to hire again, post your project and let vetted contractors come to you.
