Why Vetting Matters Before the First Nail Goes In

Hiring a tradesperson for home work — whether it's a bathroom remodel, a new roof, or electrical panel work — is one of the more consequential decisions a homeowner makes. The wrong hire can mean shoddy work, missed permits, or disputes over money that drag on for months. The right hire, on the other hand, makes the whole process feel almost easy.

The checklist below gives you a concrete set of questions to ask, documents to request, and signals to watch for — before any work begins. If you're still deciding whether to hire out or tackle something yourself, our guide to DIY trade-offs is worth a read first.

Work through this list with every tradesperson you're seriously considering — not just the one you've already warmed to.

Credentials and Legal Standing

Ask for the tradesperson's license number and verify it through your state or local licensing board's website. Must
Request proof of general liability insurance and confirm it's current — not expired. Must
Ask whether workers' compensation insurance covers anyone who'll be working on your property. Must
Confirm the business name on any documents matches the licensed entity — not just a personal name. Should

Quotes, Contracts, and Scope

Request a written, itemized quote that separates labor, materials, and any subcontractor costs. Must
Make sure the contract spells out the full scope of work — what's included and, if possible, what isn't. Must
Ask what happens if the project scope changes mid-job — get the change-order process in writing. Must
Confirm a realistic project timeline with start and expected completion dates noted in the contract. Should
Ask what happens — and who pays — if work runs significantly over the quoted timeline. Should

Permits and Code Compliance

Ask which permits are required for the job and confirm who is responsible for pulling them. Must
Verify that required inspections are included in the project plan — don't assume they're automatic. Must
If the tradesperson says no permit is needed for work that typically requires one, get a second opinion before proceeding. Must

References and Past Work

Ask for at least two or three references from recent jobs of similar scope — not just general testimonials. Must
Contact those references and ask specifically about timeline, communication, and how issues were handled. Should
Check for complaints filed with your state contractor licensing board or your local Better Business Bureau. Should
If the project is significant, ask if you can see an example of completed work in person. Nice to have

Payment Terms

Agree on a payment schedule tied to project milestones — not one lump sum paid at the start. Must
Confirm the final payment isn't due until the work is complete and any required inspections have passed. Must
Ask which payment methods are accepted and get a receipt for every payment made. Should
Understand the warranty or guarantee offered on both labor and materials before signing. Should

Tools That Help You Stay Organized

You don't need a lot to do this well — mostly time and a willingness to ask straightforward questions. That said, a few basic items will help you keep track of what you've gathered and what still needs confirming.

Required

State or local licensing board website

Verify the tradesperson's license number, status, and any disciplinary history.

Required

Printed or digital document folder

Keep quotes, contracts, insurance certificates, and receipts organized in one place throughout the project.

Optional

Camera or smartphone

Photograph the work area before, during, and after the job to document the condition of your home.

Required

Local building department contact

Confirm which permits are required for your specific job and jurisdiction before work starts.

Once you've collected the documents and answers covered in the checklist, keep everything in one folder — physical or digital — until the job is fully complete and the final inspection (if required) has passed.

Never Skip the Insurance Verification Step

If a tradesperson causes damage to your property or a worker is injured on your job site, you could be held financially responsible if they don't carry proper insurance. Don't take their word for it — ask to see the actual certificate and call the insurer to confirm the policy is active. This step takes five minutes and can prevent a very costly outcome.

Red Flags Worth Knowing About

Most tradespeople operate honestly and professionally. But a few patterns show up repeatedly in homeowner complaints, and it's worth knowing them in advance.

Pressure to Skip Permits or Pay All Upfront

If a tradesperson suggests skipping permits to save time or money, that's a serious warning sign. Unpermitted work can create legal complications when you sell your home and may not meet safety standards. Similarly, be cautious of anyone who requires full payment before work has started — a reasonable deposit is normal, but full upfront payment removes your leverage if something goes wrong.

Vague or Verbal-Only Agreements

A quote delivered only by word of mouth, with no written breakdown, leaves you without recourse if the final bill looks very different. Legitimate contractors expect to put things in writing. If someone resists a written contract without a clear explanation, treat that resistance as informative.

Unusually Low Bids

A bid that's dramatically lower than others you've received can signal that a contractor plans to cut corners, use lower-grade materials, or add costs back in through change orders once work is underway. Compare quotes carefully and ask each bidder to explain any significant price differences.

Ultimately, the goal isn't to approach every tradesperson with suspicion — it's to ask the same questions of everyone so you can compare fairly and catch problems early. A professional who's done this job many times will expect these questions and answer them without hesitation.
