Questions to ask a Contractor on Your New or Remodel Project
Hiring a contractor for a new, remodel or renovation project is a significant financial decision. The interview process is your opportunity to separate qualified candidates from ones who will cost you time, money and headaches. Knowing the right questions to ask a contractor and understanding what the answers should tell you, are crucial. It’s the difference between a project that goes well and one you wish you’d never started.
This post covers two things: how to build a qualified list of contractors before the interview begins, and the specific questions to ask a contractor when you sit down.
Before the Interview: Building Your Contractor List
The interview process only works if you’re starting with credible candidates. A few steps worth taking before you pick up the phone:
#1 Get a Referral From Someone You Trust
A personal referral from someone who has recently completed a similar project is still the most reliable starting point.
If the experience was positive, there’s a reasonable chance yours will be too. Quality contractors who build their business on referrals, work hard to maintain that reputation — it’s their best marketing.
#2 Consider Whether You Need a Specialist
If your project is limited to a single trade a specialty contractor may be all you need. However, questions you ask a contractor applies here as well. A specialty contractor might used for replacing cabinets, replacing flooring or updating a bathroom.
Hiring a specialty contractor directly cuts out the general contractor markup and gets you someone whose entire business is focused on that one type of work.
However, if your project is complex and involves multiple trades, a general contractor may be the answer. They will manage the coordination of multiple trades on your behalf saving you significant.
#3 Verify Licensing, Bonding, and Insurance
Any reputable contractor will provide documentation of their business license, bond (where required), and certificate of insurance without hesitation.
At minimum, look for commercial general liability, automobile liability, workers’ compensation, and a valid business license for your county and state. If a contractor can’t produce these, move on.
#4 Check the Better Business Bureau
The BBB is an underused resource. If the contractor is registered, you can see their rating and a three-year history of complaints. This includes what the complaints were about and how they were resolved. This can be done before you ever contact the contractor, which makes it an efficient first filter.
#5 Search Your State Contractors Board
One of the most valuable steps in vetting a contractor is running a search on your state’s Contractors Board website.
Every state maintains a licensing database that is publicly accessible and free to use. The information it contains goes well beyond what the BBB can provide.
A State Contractors Board search will typically show you the contractor’s current license status and classification. It also provides company officer information, bond type and limit, and any violations on record.
Depending on the state, violation histories generally go back five years or more. Violations can include safety violations and workmanship complaints. It can also let you know if the contractor used the services of an unlicensed subcontractor. Any of these can result in formal action, financial judgments, and license suspensions or revocations.
This is public record and takes minutes to check. Look for a contractor with a clean license history and appropriate bond coverage in good standing. This is a contractor who has operated within the rules.
A contractor with a pattern of violations — even if their BBB rating looks fine — is a different conversation entirely. Make this search a standard part of your process before any contractor sets foot on your property.
#6 Review Their Website
A contractor’s website won’t tell you everything, but it tells you enough. Look for completed project photos, an “About” section with company history and leadership. Look for trade organization affiliations, and whether they list their contractor license numbers. A well-maintained site suggests a contractor who takes their business presentation seriously, takes their work seriously as well.
#7 Require Detailed Written Estimates
Don’t accept a single lump sum number and here’s why. A detailed estimate broken down by trade and scope gives you visibility into where your money is going. It also tells you what the contractor’s overhead and profit look like, and whether the numbers are competitive.
This transparency is a quality in a good contractor. A lump sum proposal on the other hand gives the contractor room to conceal compounded markups.
A line-item breakdown gives you information needed to true up your budget and make an informed decision to proceed.
Questions to Ask a Contractor You Interview
Once you have your shortlist, here are the questions worth asking — and what the answers should tell you.
What types of work do you self-perform?
Most remodeling contractors don’t perform all the work with their own direct employees. Electricians, plumbers, and HVAC contractors are typically licensed trades hired specifically for those scopes.
That’s normal and expected. What you want to understand is which work the contractor performs directly and which work is subcontracted. You also want to know who those subcontractors are. A contractor who is vague about this warrants follow-up questions or you move on to your next choice.
Do you belong to any trade organizations?
Check active memberships in organizations like the National Association of Home Builders (NAHB) or the National Association of the Remodeling Industry (NARI). This indicates a contractor who stays current with industry practices, codes, and standards.
Both organizations maintain member directories you can use to find contractors in your area. The key word is active — a contractor who joined but doesn’t participate isn’t getting the same value from membership as one who does.
Are your prices guaranteed — and for how long?
A contractor who has properly evaluated your scope of work should guarantee their prices for 30 to 90 days. This only after they’ve visited the site, taken field measurements, and understands existing conditions. This gives you time to complete your review and decision process.
If a contractor tells you the price is only good for a day or two, that’s a red flag. It suggests either a poorly developed estimate or a pressure tactic — neither of which is a good sign for how the project will be managed.
Do you carry Commercial General Liability insurance?
Commercial General Liability (CGL) insurance protects you as the property owner. It comes into play if the contractor or their employees cause damage to your property during the course of the work.
While CGL isn’t always legally required for remodel work, carrying it is a standard practice among reputable contractors. It reflects a commitment to operating professionally. Always ask for physical proof of a current certificate of insurance — not just a verbal confirmation.
Are first and second tier permits included in your estimate?
Permit requirements vary by location and project scope, but this question is worth asking explicitly. A first tier permit is pulled by the general contractor for the overall project.
Second tier permits are pulled by individual licensed trades — mechanical, electrical, and plumbing contractors typically pull their own. Permit costs should be included in the estimate, not treated as an add-on after the contract is signed.
It’s also worth checking your homeowner’s insurance policy — some policies require that renovation work be permitted as a condition of coverage.
May I meet the owner or principal of the company?
A contractor who is serious about earning your business will welcome this request. They want to establish trust and make a personal connection. If a contractor deflects or declines a reasonable request to meet their senior leadership, pay attention to that. It reveals how they value client relationships and can signal the kind of communication you’ll experience throughout the project.
Have you ever been sued?
This question makes some people uncomfortable to ask, but it’s entirely appropriate. Being sued doesn’t automatically disqualify a contractor — disputes happen, and not every customer is reasonable.
What matters is the pattern. How many times? How many judgments were actually filed against them? A single dispute resolved years ago is very different from a recurring pattern of litigation. Court records are public, and the BBB complaint history provides additional context.
What is your safety record and safety program?
Safety on a residential or commercial remodel project encompasses more than hard hats. It includes job site cleanliness, proper equipment and cords, organized material storage, and clear access throughout the project.
A contractor with a genuine safety program will be able to speak to it specifically. They will tell you what their protocols are and how they communicate safety expectations to subcontractors.
They will also let you know how they intend to keep your property safe during construction. A contractor who hasn’t thought about this hasn’t thought enough about the job. Move on.
May I have client and supplier references?
Any contractor unwilling to provide references should be crossed off the list. Ask for recent clients — not just a curated list of best-case projects. Speak with them directly by phone rather than relying on written testimonials. Ask about the full experience: communication, problem-solving, timeline, and whether they would hire the contractor again.
Supplier references are equally valuable and rarely requested. How a contractor pays their bills tells you a great deal about how they run their business. A contractor who is consistently late paying suppliers creates friction with the trades working on your job. That friction has a way of showing up in the quality of work and the pace at which they complete their work.
Questions to Ask a Contractor and What the Answers Tell You
The goal of the contractor interview isn’t just to collect information — it’s to evaluate how a contractor communicates. How prepared are they, and whether they demonstrate the kind of professionalism you want managing work on your property.
A contractor who answers these questions confidently, specifically, and without hesitation. This contractor is one who has nothing to hide and understands what it takes to earn a client’s trust.
Vague answers, pressure tactics, missing documentation, or reluctance to engage with straightforward questions are all signals worth considering before you make a decision to sign.
