9 Contractor Red Flags Every Homeowner Should Know (2026)

Protect Yourself Before You Sign
Most contractor fraud is preventable. These 9 warning signs appear before a single dollar changes hands. If you see more than two, walk away and get competing bids.
The 9 Warning Signs
Red Flag #1: Demands more than 30–33% upfrontStandard deposits cover materials ordering — 10–33%. Demanding 50%+ (especially cash) suggests the contractor is underfunded or planning to use your money on another job. Legitimate contractors do not need you to fully fund them before work begins.
Red Flag #2: Asks you to pull your own permitsThe contractor should always pull permits in their own name. If they ask you to pull the permit, they likely are not licensed to do so — meaning the work will not be inspected and leaves you legally exposed if something goes wrong.
Red Flag #3: Pressure to sign today or "the price goes up"Material prices do not change overnight. A contractor who will not give you 48–72 hours to review a quote is preventing you from getting a second opinion. Walk away and call someone else.
Red Flag #4: Their bid is 30%+ lower than everyone elseSignificantly low bids mean one of three things: they plan to cut corners on materials or labor, they will ask for more money midway through (change orders), or they made a mistake. Competitive bids are within 15–20% of each other.
Red Flag #5: Cash only, no written contractNo legitimate contractor requires cash-only payment for a major project. In many states, a written contract is required by law for projects over $500. Your contract should specify: exact scope, materials, payment schedule, start date, timeline, and warranty terms.
Red Flag #6: PO box only — no physical business addressLegitimate contractors have a verifiable business location. A PO box is the address of a fly-by-night operation that can disappear easily. Search their company name with whichever authority licenses the trade where you live — that is a state board in some states and a city or county office in others.
Red Flag #7: Won't provide proof of insuranceAsk for a Certificate of Insurance naming you as additional insured. If a worker is injured on your property and the contractor lacks workers' comp, you may be liable. A legitimate contractor provides insurance certificates without hesitation.
Red Flag #8: Out-of-town contractors showing up after a storm"Storm chasers" follow major weather events, take large deposits, do substandard work, and disappear. If they knocked on your door unsolicited, be especially cautious. Use contractors with verifiable local history.
Red Flag #9: No license number or won't verifyMost states require licenses for roofing, electrical, plumbing, HVAC, and major remodeling. Ask for the license number and verify it with the authority that licenses the trade in your state — takes 2 minutes.
5 Protection Steps
1. Get three written quotes from contractors with verifiable local presence.
2. Verify every license at your state's licensing board before signing anything.
3. Request a Certificate of Insurance — general liability AND workers' comp. Call the insurer to confirm it is active.
4. Pay by check or credit card — never wire transfer, never cash. Credit cards offer chargeback protection.
5. Do not pay more than 33% upfront. Structure payments: deposit on signing, progress payment at a milestone, final payment only when work is completed to your satisfaction.
7 questions to ask any contractor: Are you licensed and insured in this state? Will you pull the permits? Are your workers employees or subcontractors? What is the warranty — workmanship vs manufacturer? What is the payment schedule? How will you protect my home during the project? Can you provide 3 local references from the past year?
These are the questions homeowners ask most often before starting this project - what it costs, how long it takes, what a fair quote looks like and which details change the price. Each answer below is written to stand on its own, so you can read just the one you need.
Search with the authority that licenses the trade in your state — most have a free public lookup by name, company name, or license number. Results show license status (active/expired/suspended), bond and insurance status, and any disciplinary actions.
A reasonable deposit is 10–33% of the project total to allow materials ordering. For large projects over $20,000, 10–15% is more appropriate. Never pay more than 33% before work begins. Tie remaining payments to completion milestones.
A complete contract includes: exact scope of work with material specifications, start and estimated completion dates, payment schedule tied to milestones, change order process (all additions must be in writing and signed), warranty terms for workmanship and materials, cleanup responsibility, and permit responsibility.
If a contractor takes a deposit and does not perform, you may recover it through: (1) small claims court (for amounts under $10,000–$15,000 in most states), (2) a complaint to the state contractor licensing board, or (3) a credit card chargeback if you paid by card. This is why paying by credit card is strongly recommended.
Not always — some legitimate companies expand their service area after major storms. The red flags are: they came to you unsolicited, no verifiable local presence, pressure to sign quickly, and asking you to sign an Assignment of Benefits on your insurance claim. A legitimate company will still have a verifiable license, insurance, and local references.
