What Questions to Ask a Contractor Before You Hire

Before hiring any contractor, the conversation you have with them is one of your most important tools. Most homeowners ask a few surface-level questions and go with their gut — but the right questions reveal whether a contractor is qualified, organized, and honest before a single dollar changes hands.

Here are the questions that matter, organized by category, along with what good and red flag answers look like.

Questions About Experience and Credentials

How long have you been in business, and how long have you been doing this specific type of work?

Years in business matters — but years doing your specific type of project matters more. A contractor who has been running a business for 10 years but only started doing bathroom additions two years ago is less experienced than their overall tenure suggests.

Good answer: A specific number of years, ideally with examples of similar completed projects.

Red flag: Vague answers like "a long time" or pivoting to how many projects they've done total without addressing your project type specifically.

Are you licensed for this type of work in my state?

Licensing requirements vary by state and by trade. A general contractor may be licensed but the subcontractors they use may not be. Learn more in contractor license vs. insurance for what to verify and how.

Good answer: A direct yes, with a license number you can look up.

Red flag: "We don't really need a license for this type of work" — this may or may not be true, and either way it signals you should verify independently.

Do you carry general liability insurance and workers' compensation?

Liability insurance protects your property if something is damaged during the project. Workers' compensation protects you if a worker is injured on your property. Both matter.

Good answer: Yes to both, and they offer to provide a certificate of insurance before work starts.

Red flag: Any hesitation, or "my guys are covered under my policy" without being able to show documentation.

Questions About Your Specific Project

Have you done projects like mine before? Can I see examples or speak to past clients?

This is one of the most important questions and one of the most commonly skipped. You want a contractor who has done your specific type of project — not just general renovation work.

Good answer: Yes, with photos, addresses of completed work, or references willing to talk.

Red flag: "Every project is different" used as a reason not to provide examples, or references who seem coached or are suspiciously brief.

Who will actually be doing the work — you, employees, or subcontractors?

Many contractors bid jobs and then hand them off entirely to subcontractors you've never met. That's not automatically a problem, but you deserve to know who will be on your property and who is responsible for the quality of the work.

Good answer: A clear explanation of who does what, with confirmation that the contractor will be on-site regularly to supervise.

Red flag: Evasiveness about who does the actual work, or finding out mid-project that the person you hired has handed everything off.

What could go wrong on a project like this, and how would you handle it?

This question separates experienced contractors from inexperienced ones. Every project has risks — a good contractor knows what they are and has dealt with them before.

Good answer: A thoughtful, specific answer based on your project type — for example, "on older homes we often find knob-and-tube wiring once walls open up, and here's how we handle that."

Red flag: "Nothing should go wrong" or a blank look. Every experienced contractor has a story.

Questions About the Contract and Payment

What does your payment schedule look like?

Payment schedules reveal a lot about a contractor's financial health and business practices. A standard schedule ties payments to project milestones — not to arbitrary dates or the contractor's cash flow needs.

Good answer: A deposit to start (typically 10–30%), followed by milestone-based payments, with a meaningful amount held until final completion — usually 10%.

Red flag: Asking for more than 30% upfront, or asking for large payments before milestones are reached. This is one of the most common patterns in contractor disputes.

What exactly is included in your quote — and what isn't?

A quote that looks low may be missing items that will show up as change orders later. Understanding exactly what is and isn't included upfront prevents expensive surprises. Learn more in how to read a contractor quote for what every line item should mean.

Good answer: A detailed breakdown with clear inclusions and exclusions, and a straightforward explanation of what would trigger a change order.

Red flag: Resistance to itemizing the quote, or "we'll figure it out as we go."

What is your process for handling change orders?

Changes happen on almost every project. The question is whether they're handled professionally — in writing, with agreed pricing — or informally in ways that lead to disputes. Learn more in change orders for what to expect.

Good answer: All change orders are documented in writing with costs agreed before work proceeds.

Red flag: "We'll sort it out at the end" or any resistance to putting changes in writing.

Questions About Timeline and Communication

What is your estimated start date and completion date?

Get both in writing. A contractor who can't give you a rough timeline either hasn't thought through the project or is overcommitted.

Good answer: Specific dates with a clear explanation of what could affect the timeline — permits, material lead times, inspections.

Red flag: "It depends" with no further specifics, or a completion date that seems unrealistically fast.

Who is my point of contact during the project, and how do you prefer to communicate?

Knowing who to call when something comes up — and knowing they'll actually respond — prevents a lot of frustration during a project.

Good answer: A named contact (ideally the contractor themselves or a dedicated project manager) with a clear communication preference and typical response time.

Red flag: "Just call the office" with no specific person, or a contractor who is already hard to reach during the bidding process.

How do you handle disputes if something goes wrong?

No one wants to think about this — but asking it tells you a lot. A contractor who has a clear, professional answer has dealt with issues before and resolved them. A contractor who gets defensive hasn't thought about it or doesn't like accountability.

Good answer: A clear process — fixing issues before final payment is released, mediation if needed, warranty terms in writing.

Red flag: Defensiveness, dismissiveness, or "that won't happen."

Frequently Asked Questions

What not to tell a contractor? Avoid telling a contractor your maximum budget before they give you a quote — they may simply price up to it. Also avoid mentioning that you're not in a hurry if timeline matters to you, as some contractors deprioritize projects without a deadline.
