TL;DR: A home improvement contract scam is a repair or remodelling offer designed to take your money without leaving a written record behind. Almost every warning sign the Federal Trade Commission lists is a version of the same behavior: an attempt to avoid paperwork. Cash only. Full payment before the work starts. No written contract. Pressure to decide before you have read anything. The paperwork you are being rushed past is the thing that protects you.
Every year, homeowners lose money to contractors who never intended to finish the job. This guide walks through the seven warning signs the FTC points to most often, why each one exists to stop you from keeping a paper trail, and what a legitimate contract, change order, and signature actually look like, so you can tell the difference before you pay a deposit.
Key takeaways
- The FTC red flags cluster around one behavior: avoiding written, signed, verifiable commitments.
- Never pay in full upfront, never pay in cash only, and never make the final payment before the work is done and you are satisfied.
- Verify the license with your state or county, and get proof of insurance, before anything is signed.
- Every change to the job belongs in a signed change order, not a phone call.
- Storm and disaster repairs are the busiest period for these scams, so door-to-door offers deserve the most suspicion.
The seven red flags
Five of these come straight from Federal Trade Commission consumer guidance. The last two come from what those five have in common.
A scammer:
- Says they have materials left over from a previous job. Claims of leftover materials are a common home improvement scam tactic. Treat such offers with caution and verify them before agreeing to any work.
- Pressures you for an immediate decision. The urgency is manufactured so that you do not check references or read the contract.
- Asks you to pay for everything upfront, or only accepts cash. Paying first removes the only leverage you have if the work is never finished.
- Asks you to get the required building permits. A contractor avoiding the permitting office may be unlicensed, or planning work that will not pass inspection.
- Suggests you borrow from a lender they know. The FTC warns that this can end in a loan secured against your home, which puts the house itself at risk.
- Refuses to put anything in writing. No written estimate, no written contract, no written changes. This one runs through all of the others.
- Turns up at your door after a storm. Repair crews who follow the weather are not always fraudulent, but the ones who are rely on you being in a hurry.
Why a scam depends on there being no paperwork
It is worth understanding the logic, because it makes the red flags easy to remember without a checklist.
A written record creates accountability. A signed contract fixes the price and the scope before the money moves. A permit puts the work on a public register. A signed change order records what was agreed when the job changed. Each of those documents gives you something to point at later, and gives an honest contractor something to point at too.
A person who intends to take your deposit and disappear cannot afford any of that. So the pressure to skip the paperwork is not impatience. It is the plan.
The payment rules that protect you
FTC guidance is direct about money. Do not pay the full amount upfront. Some states legally cap the down payment a contractor can request, so check with your state or local consumer agency before you agree to a figure.
Never make the final payment until the work is complete and you are satisfied with it. That last payment is the only leverage you keep once the crew is on site.
Pay in a way that leaves a record. A demand for cash, a wire transfer, or gift cards is a warning sign on a building job and everywhere else. Those payment methods are chosen because they are difficult to reverse.
How to verify a contractor before you sign
The FTC advises considering only contractors who hold both a license and insurance. Confirm the license with your state or county government rather than taking a photograph of a card at face value, and ask for proof of insurance in writing.
Then do the ordinary checks. Get recommendations from people you trust. Collect more than one estimate. Check with the local home builders association and with consumer protection officials for complaints. Search the contractor name alongside words such as scam, review, or complaint.
Some states run formal programs that are worth knowing about. Massachusetts, for example, registers home improvement contractors and backs homeowners with a complaint process and a guaranty fund. Your state may have something similar, and the FTC consumer advice site is a reasonable place to start looking.
What a legitimate paperwork trail looks like
If you are not sure whether the documents you have been given are enough, work through these six questions. A complete set answers all of them.
- Is there a written contract? With the contractor legal name, address, license number, and a way to contact them that is not only a mobile number.
- Does it describe the work? Scope, materials, and what is specifically excluded.
- Does it state the price and the payment schedule? Including the deposit, the milestones, and the final payment tied to completion.
- Does it give dates? A start date and an expected completion date, even approximate ones.
- Does it say who pulls the permits? It should be the contractor.
- Does it say how changes will be handled? This is the one most people skip, and it is the one that causes the arguments.
If one of those is blank, ask about it before you sign. Questions are cheap beforehand and expensive afterwards.
Every change belongs in a signed change order
Almost every job changes partway through. A wall opens and there is rot behind it. You decide on a different tile. That is normal, and it is not a warning sign on its own.
What matters is how the change is recorded. A change order is the short document that updates the contract: what changed, what it now costs, how the finish date moves, signed by both sides before the work happens. A contractor who handles changes with a phone call and a promise to sort it out later is either disorganized or preparing for the argument. Neither is something you should pay for.
This cuts both ways, which is worth saying. A signed change order also protects an honest contractor, because it is the proof that you approved the extra work before they paid for the materials and the labour.
After storms and disasters, raise every threshold
The FTC keeps separate guidance for post-emergency repair scams, because crews who follow the weather are a reliable pattern rather than an occasional one. After a storm you are dealing with damage, an insurer, and a deadline all at once, which is exactly the state of mind these offers are built for.
The rules do not change. They just matter more. No cash-only deals, no full payment upfront, no unlicensed crews, and nothing agreed without something in writing.
How electronic signing strengthens the trail
Signing on a phone sometimes feels less serious than signing on paper. In practice it produces a stronger record, not a weaker one.
- The document cannot be quietly edited. A completed electronic signature carries a tamper-evident seal, so standard PDF readers show if a line was altered after signing.
- The timeline is kept for you. Sent, viewed, and signed are timestamped separately, so the question of when you agreed to something has an answer that neither side can rewrite.
- It is legally recognized. Electronic signatures are enforceable in the United States under the ESIGN Act and UETA, and recognized in the European Union under the eIDAS Regulation.
That is the standard your paperwork should meet, whether or not you ever think about the software behind it. BoldSign’s design reasoning is on our feature page, and the construction picture is on eSignature for Construction.
If you are curious what a well-guarded approval conversation looks like, our Change Order Approval Agent demo is deliberately built to refuse the patterns above. It never requests payment, never touches pricing, collects only four ordinary details, and tells you to verify independently if anything seems wrong. It is one of several AI eSignature agents built on the same rules.
If you have been targeted
Stop payment where you can. Keep every document, photograph, and message, including text messages and voicemails. Report it to your local police, to the FTC at ReportFraud.ftc.gov, and to your state consumer protection office. Your report helps the FTC build cases and warn other people.
If you have already signed something you now doubt, take the document to a lawyer or to your state consumer protection office rather than to the contractor. Nothing on this page is legal advice, and a signed contract is worth a professional opinion.
Ready to put every job in writing?
A legitimate contractor has no reason to avoid a signature. BoldSign lets you and your contractor sign contracts and change orders electronically, with a timestamped, tamper-evident record of who approved what and when. It’s the exact paper trail this guide recommends.

FAQs
What are the biggest red flags of a home improvement scam?
Per FTC guidance: demands for full payment upfront or cash only, claims of leftover materials from another job, pressure for an immediate decision, asking the homeowner to pull required permits, and steering you to a lender they know. Refusing to put changes in writing belongs on the same list.
How much should I pay a contractor upfront?
Never the full amount. Some states legally cap the down payment a contractor can request, so check your state or local consumer agency. And never make the final payment until the work is done and you are satisfied.
How do I verify a contractor is legitimate?
Confirm the license with your state or county government, ask for proof of insurance, get references and multiple estimates, and search the contractor name with words like scam, review, or complaint. Report suspected fraud to the FTC at ReportFraud.ftc.gov.
Is a verbal agreement with a contractor enforceable?
It may be, depending on your state, but it is very hard to prove. Get the scope, the price, the schedule, and every later change in writing and signed, because that is the record you will need if there is a disagreement.
What should a home improvement contract include?
The contractor legal name, address and license number, a description of the work and what is excluded, the total price and payment schedule, start and completion dates, who pulls the permits, and how changes will be handled.
What is a change order, and why does it matter for scams?
A change order is a short signed document that updates the contract when the job changes, recording the new work, the new cost, and the new dates. It matters because unwritten changes are where surprise charges appear on a final invoice.
Is it safe to sign a construction document electronically?
Yes. An electronic signature is enforceable under the US ESIGN Act and UETA and recognized under the EU eIDAS Regulation, and it produces a tamper-evident record with independent timestamps, which paper does not.
A contractor is asking me to pay by wire transfer or gift card. What should I do?
Do not pay. Those methods are chosen because they are hard to reverse, and no legitimate contractor requires them. Stop, verify the company independently, and report the request to the FTC at ReportFraud.ftc.gov.
