Questions to Ask Before Hiring Any Contractor

Start with the basics that protect you legally and financially:

1. "Are you licensed? Can I see your license number?"

Most trades require state or local licensing. Write down the license number and verify it on your state's licensing board website. An active, in-good-standing license means the contractor has met training and exam requirements. If they're evasive about their license, move on.

2. "Are you insured? Can you provide a certificate of insurance?"

At minimum, they should carry general liability insurance ($1 million minimum) and workers' compensation insurance (if they have employees). Ask for a certificate of insurance — a legitimate contractor will have their insurance company send one directly. Don't just take their word for it.

3. "Are you bonded?"

Bonding provides financial protection if the contractor doesn't complete the work or performs substandard work. Not all trades require bonding, but it's an additional layer of protection. If bonding is required in your state for the type of work, verify the bond.

4. "How long have you been in business?"

A contractor who's been in business for 5+ years has a track record and a reputation to protect. They're also more likely to be around to honor their warranty. New businesses aren't necessarily bad, but a longer history provides more assurance.

Beyond basic credentials, evaluate their specific experience:

5. "How much experience do you have with this type of project?"

A contractor who specializes in your type of project will do better work, often at a fairer price. Ask how many similar projects they've completed in the past year. Ask for examples or references from similar projects.

6. "Who will actually be doing the work — you or employees/subcontractors?"

If the person you're talking to won't be doing the work, ask about the qualifications of whoever will. If they use subcontractors, ask whether the subcontractors are licensed and insured. You want to know who will be in your home and whether they're qualified.

7. "Do you have references I can contact?"

A good contractor will provide 3-5 recent references. Call them and ask: Was the work done on time? Was the price as quoted? Was the contractor professional and communicative? Would you hire them again? If a contractor can't or won't provide references, that's a red flag.

8. "Are you certified by any manufacturers or industry organizations?"

Manufacturer certifications (e.g., GAF Master Elite for roofing, NATE for HVAC) indicate the contractor meets specific installation standards. Industry organization memberships show commitment to professional standards. These aren't required but are positive indicators.

Get the details you need to evaluate the quote and avoid surprises:

9. "Can you provide a written, itemized estimate?"

A verbal quote isn't a quote. You need a written estimate that breaks down labor, materials, permits, and any other costs. Itemized estimates are easier to compare and hold the contractor accountable. If they won't provide a written estimate, don't hire them.

10. "Is this a firm quote or an estimate?"

An "estimate" can change; a "firm quote" or "bid" is a fixed price. Know which you're getting. For well-defined jobs, insist on a firm quote. For jobs where the full scope may not be known until work begins (like some plumbing repairs), ask for a "not to exceed" cap.

11. "What's not included in this quote?"

This may be the most important question. Ask specifically about: permits, disposal of old materials, wall repair (if they need to cut into walls), cleanup, and any potential additional work they might discover. Knowing what's excluded helps you compare quotes accurately and avoid surprise charges.

12. "What's the payment schedule?"

Standard practice is a deposit (10-30%) with the balance due upon completion, or progress payments for large projects. Never pay the full amount upfront. If a contractor demands full payment before starting, that's a major red flag. Also ask about accepted payment methods — be cautious of cash-only requests.

Understand what happens during and after the project:

13. "When can you start, and how long will the project take?"

Get a specific start date and estimated completion date in writing. Ask what could cause delays (weather, material availability, change orders). A contractor who's booked months out may be worth the wait — it indicates they're in demand. But make sure the timeline works for your needs.

14. "What warranty do you provide on your work?"

There are typically two warranties: the manufacturer's warranty on materials and the contractor's workmanship warranty on labor. Get both in writing. A workmanship warranty of at least 1-2 years is standard. Ask: What's covered? What's excluded? How do you make a claim? Is the warranty transferable if you sell your home?

15. "How will we communicate during the project?"

Ask how they prefer to communicate (phone, text, email), how often they'll provide updates, and who your main point of contact will be. Clear communication prevents misunderstandings and keeps the project on track. If they're hard to reach before you hire them, they'll be harder to reach after.

Regardless of how they answer the questions above, watch for these warning signs:

• High-pressure tactics: "This price is only good today" or "I have materials left from another job" are pressure tactics, not real deadlines.
• Demands for full payment upfront: This is a common scam. Never pay more than 10-30% upfront.
• Cash-only requests: May indicate tax avoidance, lack of insurance, or an intention to disappear.
• No written contract: A verbal agreement is not a contract. Everything should be in writing.
• Unwillingness to pull permits: If a job requires a permit and the contractor suggests skipping it, they're asking you to cut corners.
• Unmarked vehicle or no business address: A legitimate contractor has branding and a verifiable address.
• Unusually low bid: A bid 30%+ lower than others may indicate cutting corners, using inferior materials, or a plan to add charges later.
• Poor communication: If they're slow to respond, miss appointments, or seem annoyed by your questions before you hire them, it won't improve after.
• No references or bad reviews: If they can't provide references or have consistent negative reviews, move on.

Even after choosing a contractor, protect yourself throughout the project:

• Get everything in writing: The contract should include scope of work, materials, price, payment schedule, timeline, and warranty terms. Don't sign anything with blank spaces.
• Never pay in cash: Pay by check or credit card so you have a record. Credit cards also provide dispute protection if the work isn't completed.
• Don't make the final payment until you're satisfied: Hold the final payment until the work is complete, the site is cleaned up, and you've inspected the results.
• Document the work: Take photos before, during, and after. Keep all receipts, contracts, and warranties in a file.
• Communicate concerns promptly: If you see a problem, address it immediately — don't wait until the project is complete. Most issues are easier to fix early.
• Check the work: Before making the final payment, inspect the work carefully. If something isn't right, don't pay until it's fixed.
