Common Home Renovation Scams in the US and Canada

BBB home-improvement warning

Home renovation and repair scams have impacted many people across North America. A recent survey found roughly 1 in 10 Americans have experienced a contractor scam, with average losses around $2,426 (National Council on Aging). Such scams target both homeowners and contractors, exploiting trust and urgency. Below we separate common schemes by who the scammers prey upon—homeowners and contractors—highlighting how they work, warning signs, real examples, and tips to avoid them.

Scams Targeting Homeowners

1) Door-to-Door “Leftover Materials” (Paving / Roofing / Masonry)

How it works. While many legitimate home renovation companies use door-to-door outreach as part of their sales strategy, some scammers exploit this method. In the scam version, a “contractor” shows up unannounced claiming to be working nearby and offers a steeply discounted job using “leftover materials.” They often demand a cash deposit on the spot, then deliver shoddy, incomplete, or no work at all. This “travel crew” con has been repeatedly reported across the US and Canada (see BBB and police warnings).

Red Flags (Possible Scam):

  • Claims of a “today-only” deal tied to leftover materials.
  • Demands a large deposit or full payment up front in cash.
  • Out-of-area vehicle plates, no permanent local address, or no verifiable licence.
  • Pressure to make a decision immediately without time to verify credentials.

Green Flags (Often Legitimate Door-to-Door):

  • No deposit required — payment is due only upon job start or completion.
  • Provides clear written contract, proof of licence/insurance, and local references.
  • Willing to schedule the work for a later date to give you time to verify their company.
  • Company branding on vehicles, uniforms, and business cards that match online listings.

Real Examples — The Good and the Bad:

  • Positive: In Alberta, a homeowner reported that a local roofing company rep knocked on their door after finishing a job in the neighbourhood. The rep pointed out visible storm damage, showed ID, and provided references from nearby homeowners. The company scheduled an inspection for the next day, required no deposit, and completed the roof replacement within a week at a fair price. The homeowner later left a 5-star BBB review praising the convenience and professionalism of the door-to-door contact.

  • Negative: Police in Kingston, Ontario arrested individuals running a door-to-door paving scam after taking deposits and failing to complete work (CTV News). Similar cases have been reported by BBB across multiple provinces and states.

How to Protect Yourself:

  • Welcome legitimate reps but take the time to verify their company’s history, licence, and insurance.
  • Ask for a written, detailed quote and compare it with at least two others.
  • Avoid paying a deposit — especially in cash — unless it’s a reputable company you’ve verified and the deposit terms are standard in your area.
  • Trust your instincts: professional door-to-door reps will respect your decision to research before committing.

2) “Free Inspection” & Unnecessary Repairs

How it works. Someone appears (or texts/calls) offering a free roof/chimney/furnace inspection, “finds” serious issues, and pushes for immediate paid work, often demanding large upfront payment via cash, wire, or gift cards.
Red flags. Unsolicited “we saw damage,” pressure to act fast due to a “special” price, demand for big deposit or full payment up front.
Real examples & guidance. BBB repeatedly warns about “free roof inspection” ploys, especially after storms (BBB alert; local TV+BBB reminder: WRAL). The US FTC outlines do’s/don’ts for home repair scams—get multiple written estimates, never pay in cash/wire, and insist on a written contract (FTC).
Prevent it. Thank them, then independently call a trusted local pro for a second opinion. Use traceable payment and a written contract.

3) Big Upfront Deposit & Vanishing Contractor

How it works. A contractor secures a hefty deposit “for materials” or to “hold your spot,” then never starts, starts and abandons, or endlessly delays.
Red flags. Cash or large up-front payment, refusal to provide a written contract/receipts, sudden radio silence.
Real examples & guidance. BBB documents cases where deposits were taken and work never completed (BBB). Red-flag lists (lowball bids, cash-only, no contract) are also covered by national outlets (U.S. News & World Report).
Prevent it. Keep down payments reasonable (often 10–30% where permitted), tie progress payments to milestones, and always use a detailed written contract.

4) Bait-and-Switch / “Escalating Project”

How it works. A very low initial bid gets the job; once demolition begins, “new problems” appear that dramatically raise the price. If you balk, they threaten to walk, leaving your home torn up.
Red flags. One bid far below others, immediate discovery of expansive hidden issues, refusal to document change orders.
Guidance. BBB notes this “we found more problems” pattern as a hallmark of shady operators (BBB). Experts advise getting clustered, comparable bids and requiring signed, priced change orders (U.S. News & World Report).
Prevent it. Pause and get an independent second opinion before authorizing costly scope changes; keep payment leverage until satisfactory completion.

5) Post-Disaster “Storm Chaser” Crews

Tarping a storm-damaged roof (USFWS/Public Domain)

How it works. After severe weather, roving crews solicit urgently, sometimes claiming affiliation with insurance or government. They push for quick signatures, ask to handle your claim, or try to get you to sign over insurance proceeds. Work is substandard or never completed.
Guidance & law. BBB repeatedly warns about storm chasers (BBB). In Texas, it’s illegal to waive an insurance deductible—a common storm-chaser pitch (Texas Dept. of Insurance). Multiple state AGs issue similar disaster-fraud alerts (e.g., GA AG).
Prevent it. Contact your insurer first, choose established local contractors, verify licences/permits, and never sign assignment-of-benefits without counsel.

6) Financing & Home-Equity Traps

How it works. Bad actors steer homeowners into predatory financing (home-equity loans, second mortgages, reverse mortgages). Funds are released to the contractor, who disappears or barely works—leaving you with debt.
Recent case (Canada). Toronto Police/CP24 reported arrests after homeowners were coached to obtain mortgages; bank drafts were taken and renovations not completed—losses near $296,000 (CP24).
Prevent it. Arrange your own financing via your bank; never sign liens/loans you don’t fully understand; schedule lender disbursements by milestones.

Scams Targeting Contractors

1) “Out-of-Town Client” Fake-Check / Overpayment

Counterfeit cashier’s check example (CC BY-SA)

How it works. A “remote” client (often by text/email) quickly accepts your bid and sends an overpayment by check, then asks you to refund the excess or pay a third party. Weeks later, the check bounces and you’re out the refund.
Guidance. The US FTC explains how fake checks clear initially, then reverse—leaving you liable (FTC: Fake checks and your bank). Local reports show contractors targeted with this pattern via Facebook/marketplaces (e.g., Austin-area coverage: FOX 7 Austin).
Prevent it. Never forward funds for a client; refuse overpayments; wait for final bank verification and use secure payment rails.

2) Fake Supplier / Materials & Invoice Fraud

How it works. A “discount supplier” builds trust with small orders, then disappears after a large prepaid shipment. Variants include fake invoices (or payment-detail changes via business email compromise).
Evidence & tips. Construction trade press and finance/security orgs document material/vendor fraud and widespread invoice fraud losses (Construction Dive; CPA guidance for construction: PBMares; BBB on unusual invoices: BBB business tip).
Prevent it. Rigorously vet new vendors, start with small test orders, use call-back verification for any changed payment instructions, and lock down pickup rules at supply yards.

3) Licence/Permit Impersonation (agency “fee due now”)

How it works. Callers/texts pretend to be the licensing board/building department, claiming your licence is suspended or a fine is due—pay immediately by phone to avoid enforcement.
Evidence. California’s DCA/CSLB reported text/phone scams impersonating staff and threatening licence action (CA DCA/CSLB alert). Washington’s L&I (via industry associations) warns that they never call demanding reinstatement payments (BIAW recap). Oregon’s CCB has issued similar alerts (AGC Oregon).
Prevent it. Hang up; call the agency back using the official number on your licence/website. Never pay fees from a link or number a random caller gives you.

4) Business Directory & Vanity Award Schemes

How it works. Emails/calls “congratulate” you for a Top Contractor award—just pay for the plaque/listing. Or they send invoices for listings/ads you never ordered.
Guidance. BBB details how vanity awards and fake directories extract fees for worthless listings (BBB on vanity awards; BBB directory scams). AP News also highlights phony invoice scams hitting small businesses (AP).
Prevent it. Don’t pay to “claim” an award; verify any invoice against internal purchase records; require secondary approval for all advertising/listing spend.

Quick Reference: How to Protect Yourself

  • For homeowners: Get 3 written bids, verify licence/insurance, demand a detailed contract, use milestone payments, and be skeptical of unsolicited offers (FTC basics; BBB tips).
  • For contractors: Verify remote clients with a live call/video, never pass through money/overpayments, vet new suppliers, and train staff on invoice/BEC red flags (FTC fake checks; Construction Dive).
