Questions Worth Asking Before Any Contractor Sets Foot in Your Home

Licensing requirements vary significantly by state and by trade. An electrician in California faces different requirements than one in Texas, and a general contractor may hold a state license that doesn't cover specialized plumbing or HVAC work. Ask directly which license applies to your project, and ask to see the license number — then verify it independently through your state's contractor licensing board website.

Working with an unlicensed contractor can void your homeowner's insurance coverage for work-related damages and leave you with no formal recourse if something goes wrong. This is a non-starter question, not a nicety.

Liability insurance covers damage the contractor causes to your property. Workers' compensation covers injuries sustained by workers on your job site. Without both, you could be legally liable for an injured worker's medical costs or left paying out of pocket for property damage that occurred during the project.

Ask for certificates of insurance — not just a verbal confirmation — and verify that the policy is current. Policies can lapse between when a contractor first showed you proof and when work begins. A quick call to the insurer to confirm active coverage is a reasonable step for larger projects.

Many contractors subcontract portions of a job, sometimes the majority of it. This isn't inherently problematic, but it does mean the person you interviewed and vetted may not be the one swinging the hammer. Ask which parts of the project will be handled by employees versus subcontractors, and ask whether those subcontractors are licensed and insured as well.

You have every right to know who will be in your home. If a contractor is vague or dismissive about this question, that's worth noting before you proceed.

For many projects — structural changes, electrical upgrades, new plumbing, room additions — permits are legally required. Some contractors prefer to skip this step because inspections slow down the work. But unpermitted work can create real problems: it may not meet code, it can complicate a future home sale, and your insurance company may not cover losses tied to unpermitted modifications.

Make it explicit in the contract that the contractor is responsible for obtaining all required permits and scheduling inspections. Never assume permits are being handled unless it's written down. For more on why this matters, see what permits actually cover and when you need one.

A portfolio of photos is useful, but a conversation with a past client is invaluable. Ask for references specifically from projects similar in scope and type to yours — completed within the last two years ideally. Then call those references and ask targeted questions: Was the project completed on time? Did the final cost match the estimate? How did the contractor handle problems that came up mid-project?

A contractor who hesitates to provide references, or provides only one, should prompt more scrutiny. A professional with a strong track record will have no trouble connecting you with satisfied clients.

How a contractor structures payment reveals a lot about their financial stability and professional practices. A reasonable payment schedule is typically tied to project milestones — an initial deposit, payments at defined stages, and a final payment on satisfactory completion. Be wary of any contractor who demands a large upfront sum (often more than 10–30% is a red flag, though norms vary by trade and project size) or who wants full payment before work is done.

Payment terms should be explicitly spelled out in the contract. This protects you from a contractor who disappears mid-project and gives you leverage to withhold final payment if the work isn't completed to the agreed standard.

Asking for a timeline isn't just about managing your own schedule — it's a way to gauge how organized and experienced the contractor is. A professional should be able to give you a realistic start date, an estimated completion range, and a candid list of factors that could push that timeline: material lead times, weather, permit inspection delays, or discoveries once walls are opened.

A contractor who promises an unrealistically fast timeline to win the job, or who can't articulate potential delays, may be setting you up for a frustrating experience. Build in reasonable buffer time, and make sure the contract includes language around how schedule changes are communicated.
