How to Hire a Contractor Safely (And Avoid Getting Scammed)

Updated March 2026 · 12 min read

Contractor fraud costs American homeowners an estimated $17 billion annually. The most common victims aren't people who don't do their homework — they're people who did some homework but missed a few critical steps. This guide covers every step of the contractor hiring process, the red flags that experienced homeowners watch for, and the contract provisions that protect you when things go wrong.

    The single most important rule: Never pay more than 10–15% upfront, and never pay in cash. These two rules alone eliminate the majority of contractor fraud scenarios.
  

Step 1: Before You Call Anyone

Define the Scope in Writing

Before getting quotes, write a detailed description of exactly what you want done. The more specific you are, the more accurate and comparable your quotes will be. Include: specific materials you want (or ask the contractor to specify), timeline expectations, who handles permits, how changes will be handled. Vague scope = vague quotes = surprises when the bill comes.

Know the Going Rate

Use our cost calculator to estimate what your project should cost before getting quotes. If a bid comes in dramatically below the others, something is wrong — either the scope isn't understood, cut corners are planned, or they intend to "discover" problems during the work that drive the final price up.

Step 2: Finding Legitimate Contractors

Best Sources (Ranked)

Personal referrals from people who've used the contractor recently — not just "my cousin knows a guy," but someone who hired them for a similar project in the last 2 years
Local contractors with 5+ years of verifiable history — an established business with reviews going back multiple years is harder to fake
State licensing board search — your state has a public database of licensed contractors; use it before calling anyone
BBB (Better Business Bureau) — not perfect, but useful for flagging known problem contractors
Angi, HomeAdvisor, Thumbtack — legitimate platforms, but verify their claimed information independently — these platforms don't verify licenses in all states

What to Avoid

Contractors who approach you unsolicited after a storm ("storm chasers")
Contractors who don't have a local address or office
Anyone who asks you to pull your own permit (they usually mean they can't pull it themselves because they're unlicensed)

Step 3: Vetting Every Contractor

The 5-Point Verification Checklist

Verify their state contractor license number on your state's licensing board website
Request a Certificate of Insurance showing general liability ($1M+) and workers' compensation — call the insurance company to verify it's current
Ask for 3 references from similar projects in the last 12 months — and actually call them
Check their physical address exists — Google Street View the business address they give you
Search "[company name] + complaint" online and check court records in your county

Step 4: Getting and Comparing Quotes

Get a minimum of 3 bids. Ideally 4–5 for projects over $15,000. Request that all bids itemize the same line items so you can compare apples to apples. Ask each contractor to specify:

Exact materials (brand, model number, grade)
Labor hours or days estimated
What's explicitly NOT included
Payment schedule milestones
Their policy on change orders
Who their subcontractors are and how they're vetted

    The middle bid rule: The lowest bid is often low for a reason. The highest isn't necessarily the best. The middle 1–2 bids from thoroughly vetted contractors tend to be the best value. If one bid is 30%+ lower than the rest, ask them to explain line by line why — the explanation will be revealing.
  

Red Flags: Walk Away Immediately

🚩 Demands for Large Upfront Payment

Legitimate contractors typically request 10–15% down to order materials. Anyone asking for 30–50% or full payment upfront is either going to disappear with your money or has cash flow problems severe enough to risk your project. Standard payment structure: 10% down, progress payments tied to milestones, 10% held until completion and inspection.

🚩 "Cash Only" Discount

The "cash discount" exists because cash is untraceable. If things go wrong, you have no record of payment, no bank dispute, and no way to prove what you paid. Pay by check (traceable) or credit card (chargeable back if they disappear).

🚩 Pressure to Sign Now

"This price is only good today." "Another client wants this slot." "Materials prices are going up next week." These are sales tactics. A legitimate contractor will give you time to review a contract and get other bids. Any contractor pressuring you to sign immediately is not acting in your interest.

🚩 Wants to Skip the Permit

"We can do this without a permit, save you the hassle." Permits exist to protect you — they trigger inspections that verify work meets code. Unpermitted work can: void your homeowner's insurance claim if something goes wrong, require expensive remediation when you sell, and create legal liability. Always require permits for work that legally requires them.

🚩 Can't Provide Insurance Certificates

If a worker is injured on your property and the contractor doesn't have workers' compensation insurance, you can be liable for their medical costs. This is not theoretical — it happens. Request a certificate of insurance naming you as "additional insured" and verify it's current with the insurer.

Step 5: The Contract Must-Haves

✅ What Every Contract Should Include

Complete scope of work in specific detail — if it's not in the contract, it's not included
Materials specifications — brand, model, grade, quantity
Payment schedule tied to milestones — not time-based, milestone-based
Start and completion dates with penalty clause for delays not caused by you
Change order process — any change to scope requires written change order signed by both parties before work begins
Warranty terms — minimum 1 year on labor, plus manufacturer warranties on materials
Dispute resolution process — mediation before litigation saves everyone money
Lien waiver provision — contractor provides signed lien waivers from all subcontractors upon completion
Cleanup responsibility — who hauls debris, who pays for disposal
Permit responsibility — contractor pulls and pays for all required permits

Managing the Project

Once work begins:

Document everything — daily photos of progress, written records of conversations that matter, all change orders in writing
Don't pay ahead of progress — payments should follow completion of milestones, not the calendar
Be available but not hovering — contractors work better with a responsive client, but micromanagement creates friction. Set communication expectations at the start.
Final payment contingent on completion — hold 10% until final walkthrough, punch list completion, and all required inspections pass
