How to Hire a Contractor: Questions to Ask Before You Sign

Picture three estimates spread across your kitchen table. One runs two pages, with a scope of work, a payment schedule and a paragraph about warranty coverage. One is a single line on company letterhead. The third is a number someone texted you after walking around the house for ten minutes. The prices are different, but the bigger difference is how much each one tells you about how the job will actually go.

Hiring well comes down to asking the right questions before anything is signed, then getting the answers on paper. The questions below work for most home projects, from a water heater swap to a full roof replacement. A few may feel awkward to ask. A contractor who runs a well-organized shop will not mind them, and many will answer before you finish the sentence.

Start with licensing and insurance

Licensing rules for contractors vary a lot by state, and sometimes by city or county. Trades like electrical, plumbing, HVAC and roofing often need a specific license or registration, while small handyman jobs may need little or none depending on where you live. Ask which license the contractor holds, then look it up yourself on your state or local licensing board's website. A license number painted on a truck door is a start, not proof.

Insurance matters just as much. Ask for a certificate of insurance showing general liability coverage, and ask whether the company carries workers' compensation for its crew. If a worker is hurt on your property and the contractor has no coverage, the question of who pays can land uncomfortably close to home. Asking the contractor's insurance agent to send the certificate directly to you is a simple way to know it is current.

• Which license do you hold for this type of work, and where is it issued?
• Can your insurance agent send me a current certificate?
• Is your crew employed by you, or are they subcontractors with their own coverage?

Ask how the job will actually run

A price tells you what the job costs. It does not tell you who shows up, when they arrive or what happens if something unexpected turns up behind a wall. Ask who will be on site each day and who your main point of contact will be. On a bigger project, knowing that one person answers your calls heads off a lot of frustration.

Ask for a realistic start date and a rough duration, then ask what tends to push those dates. Weather, backordered equipment and inspection scheduling are common culprits. A contractor who names those risks up front is usually easier to work with than one who promises a date that sounds too good.

Then talk about daily life in the house. Where will materials be stored? Will the water, power or heat be off at any point, and for how long? How will floors, plants and furniture be protected? Which door will the crew use? These small questions shape how the week feels while you are living through it.

Talk about money before anything is signed

Money conversations get easier when they happen early. Ask how much deposit is required and what it pays for. Some states limit how large an upfront deposit can be for home improvement work, so check the rules where you live. A reasonable deposit often lines up with materials that must be ordered. A demand for most of the price before any work starts deserves a closer look.

Ask how the rest will be paid. Payments tied to finished stages of work (rough-in complete, inspection passed, final walkthrough done) keep both sides focused on the same milestones. If financing is offered, read that paperwork on its own terms rather than as part of the sales conversation.

Ask how changes are handled, too. Almost every project turns up at least one surprise. A written change order that describes the new work and its price, signed by both of you before the extra work starts, protects you and the contractor alike.

Pin down permits, inspections and cleanup

Permit requirements depend on your city or county and the type of work. Replacing a furnace, adding a circuit, re-roofing or moving plumbing often needs a permit, while painting a bedroom usually does not. Ask whether this job needs one and who will pull it. In most cases the licensed contractor should handle it, since the permit ties the work to someone responsible for meeting code.

Ask when inspections happen and if someone needs to be home for them. Keep copies of the permit and the final sign-off with your house records. They can matter later when you sell, refinance or file an insurance claim.

On larger jobs, ask about lien waivers. In many states, a supplier or subcontractor who goes unpaid by your contractor can file a lien against your property, even if you paid the contractor in full. A lien waiver is a signed statement that a party has been paid. Lien laws differ by state, so ask how the contractor handles them and check your own state's rules.

Cleanup is the piece people forget. Who hauls away the old shingles, the old tank or the drywall scraps? Is disposal in the price? Will the crew sweep the yard for stray nails after a roof job? Get those answers in writing along with everything else.

Red flags worth a second look

Most contractors are honest people trying to do solid work. A few patterns, though, should make you pause:

• Pressure to sign today to hold a price, especially right after a storm
• A request for cash only, or payment to a personal account
• No written estimate, or an estimate with no scope of work
• Reluctance to share a license number or insurance certificate
• An offer to skip the permit to save time
• A door-to-door pitch claiming your insurance will pay for everything

None of these automatically means a scam. Each one is a reason to slow down, ask more questions and get another opinion. For some sales made at your home, federal or state rules may give you a short window to cancel. The details depend on your state and the type of sale, so ask about cancellation rights and read that part of the contract before you sign.

A question list for the kitchen table

Keep this on your phone and use the same list with every contractor you interview, so the answers are easy to compare:

• What exactly is included in the scope of work, and what is excluded?
• Which license do you hold, and can I verify it online?
• Can I see a current certificate of insurance?
• Who will be on site, and who is my main contact?
• Do you pull the permits, and when are inspections?
• What deposit do you need, and what is the payment schedule?
• How do you handle change orders?
• What does your labor warranty cover, and what does the manufacturer cover?
• Can you share a few recent customers I could call?
• What does cleanup include?

A contractor who answers most of these clearly, and puts the answers in the contract, gives you a solid basis for comparing bids on more than price.

After the job wraps up

File the contract, permit, warranty papers and receipts in one place, along with the contractor's contact details. The next time a project comes up, you will start with a record of what went well and what you would ask differently.
