How to Hire a Contractor Without Getting Burned
Most bad projects trace back to skipping a few basic checks. These 12 questions — and the red flags behind them — protect your home and your money.
Updated July 10, 2026 · 9 min read
Whether it’s a roof, a remodel, or a new water heater, the single biggest factor in how a project goes isn’t the material — it’s who you hire. A great contractor makes a big job feel easy; the wrong one turns a small job into months of stress, change orders, and lien threats.
This is the checklist we’d use ourselves. Ask these 12 questions before you sign anything, and know the red flags that mean you should keep looking.
Before you get quotes
Do this groundwork so you can compare bids fairly:
- Write down the scope in plain words — what "done" looks like to you.
- Line up 3 quotes for the same scope so you’re comparing like-for-like.
- Decide your must-haves vs. nice-to-haves before anyone starts upselling.
The 12 questions to ask
Ask every one of these. A confident, reputable pro will answer without hesitation:
- Are you licensed for this work, and can I have your license number?
- Do you carry liability insurance and workers’ comp? (Ask for certificates.)
- Will you pull the required permits?
- Who will actually be on my job — your crew or subcontractors?
- Can I see recent, local references and photos of similar work?
- What’s your detailed, itemized written estimate?
- What’s the payment schedule, and what deposit do you require?
- What’s your timeline, and what could delay it?
- How do you handle changes and unexpected problems (change orders)?
- What warranty do you offer on labor, separate from material warranties?
- Who’s my point of contact day-to-day?
- What does cleanup and final walkthrough look like?
Red flags — walk away if you see these
Any one of these is a reason to be cautious; several together, walk away:
- Demands a large cash deposit (over ~30%) or full payment upfront.
- No written contract, or a vague one-line estimate.
- No verifiable license or insurance, or dodges the question.
- Pressure tactics — "today only" pricing, or door-knocking after a storm.
- No local references, or a business address you can’t verify.
- Wants you to pull the permit yourself (often a sign they can’t).
Protect yourself in the contract
Get everything in writing: scope, materials (brands and models), total price, payment schedule tied to milestones, start and finish dates, and warranty terms. Never make a final payment until the work is fully complete, inspected where required, and you’ve done a walkthrough. For larger jobs, understand lien waivers — a signed waiver from the contractor and their suppliers protects you from being billed twice if they don’t pay their own subs.
A fair deposit is typically 10–30% to secure materials and scheduling, with the balance tied to progress. That structure keeps everyone motivated and keeps your money safe.
Frequently asked questions
How many quotes should I get?
Three is the sweet spot — enough to spot an outlier (too high or suspiciously low) without dragging the process out. Compare scope and inclusions, not just the bottom-line number.
Is the lowest bid ever the right choice?
Sometimes, but a bid far below the others usually means something is missing — cut corners on prep, cheaper materials, no permit, or a plan to make it up with change orders. Ask why it’s lower before you choose it.
Should I pay in cash for a discount?
Be careful. A cash-only deal with no paper trail leaves you with no recourse if something goes wrong, and it can be a sign the contractor isn’t properly licensed or insured. Always keep a written contract and records.
What if the work goes wrong?
A written contract, permits, and a workmanship warranty are your protection. Document everything with photos and dates, communicate issues in writing, and for licensed trades you can escalate to the state licensing board if needed.
