15 questions to ask contractors

Did you know that hiring a qualified contractor is one of the most important parts of starting a new home project? A trustworthy pro with a good reputation and experience can make a major difference. But which questions are the most important to ask during the interview process, and how do you evaluate the quality of an answer? HomeAdvisor consulted contracting experts to create the ultimate list of questions to help you learn everything you need to know in order to confidently choose the right pro for the job – and head off common construction problems.

#1 “How long have you been in this business?”

Contracting businesses in operation for many years have worked through a lot of the growing pains that many companies deal with early on.

“Companies with experience have created systems and controls to ensure their work is on time, on budget and of the highest quality,” said Ken Kelly, President of Kelly Roofing in Naples, Florida.

You may decide to hire a contractor who has years of experience in the industry, but is a relatively new business owner. If so, consider starting him or her off with a smaller project, like handyman services. If you’re satisfied, you can confidently move on to the next project.

“Most home improvement business owners were in the trade at some point before starting their business,” Ron Hall, Sales Manager of Russell Roofing in Philadelphia, said. “So they have technical experience.”

Find several contractors near you and do your research ahead of time on any contractor you’re thinking of working with. If you find anything that makes you worry, ask about it. Ultimately, contractors prefer to address any concerns you might have, rather than be removed from the running.

#2 “Do you have a contracting license?”

Cities, states and even counties have different requirements on whether contractors must get a license or an alternative credential. As a homeowner, you’ll want to make sure that yours has gone through all of the necessary channels to obtain any required certifications specific to their field of expertise — for example, you wouldn’t want to hire a roofer whose license is in carpentry. Having a business license alone is not enough. While it allows individuals to operate a business, it doesn’t mean that they are a licensed or credentialed contractor.

This resource breaks down state requirements for working as a contractor, and if your state requires one, you can verify that a contractor is licensed using this site.

#3 “Can I see your certificate of insurance?”

Financial background checks are important. Asking a contractor if he’s insured isn’t as telling as seeing how he is insured. Contractors should have both workers’ compensation and liability insurance specifically for the type of job they perform. Taking a look at certificates of insurance will give you the peace of mind that he’s not insured in an entirely different capacity than the job you’re hiring him for.

#4 “Will you obtain the permits and set up the inspections required for this job?”

Not every job requires permits or inspections, but most remodeling projects that in some way change the structure of the home do. Your contractor should not only know what kind of permits you need and how to get them, but also be willing to pull them for you. Depending on where you live, a building permit costs between $405 and $2,230.

#5 “What is our timeline for completion?”

It’s important for homeowners to have a clear picture of when contractors will start and complete a project, and be aware of any circumstances that might affect that schedule. Here are a few additional questions that will further clarify your projected timeframe:

  • Are there any other projects you’re working on now that could affect our schedule?
  • Do you have any current bids that haven’t been finalized that could impact this job?
  • How will necessary changes to our timeline be addressed?

#6 “What is the payment schedule?”

The Better Business Bureau advises never paying for the full price of contracting work upfront, and a reputable contractor shouldn’t ask you to. But it’s important to discuss payment terms before construction begins. You should also be aware of exactly how much is due and when. This is true whether you’re working with home service pros every homeowner needs, or on a larger project like a home addition or major remodel.

#7 “Will I have a dedicated team working on my job?”

Contracting companies often work on multiple projects at a time, so it’s important to verify that you can count on consistency in who comes to work on your home each day. Here’s a look at other questions to ask your contractor.

  • Will the same team be working on my home each day?
  • Who is the project manager, and what specifically will he oversee each day?
  • Do you work with subcontractors? If so, what have you done to properly qualify them, and are they covered by your liability and worker’s compensation insurance?
  • How often will the business owner check in on the progress of the project?

#8 “What way would you like me to get in touch with you?”

Identify a designated point of contact, as well as the best way to reach that person. Find out what times he’ll be available to respond to you, as well as the method of contact he prefers. Finally, ask for a general timeframe that you should expect to hear back from him.

#9 “What is your working day like?”

It’s important for both homeowners and contractors to know what to expect on construction days before work begins. This is true even if you aren’t home while the team gets to work. The targeted questions you’ll want to ask include:

  • What are the approximate start and end times for construction day(s)?
  • Do I need to remove any items that are in or near work areas?
  • What will the noise level be like?
  • Do you need me to be home at any point during the day?

You should also advise your contractor on key information about the project prior to your start date. This includes:

  • The parking situation in your neighborhood
  • Which restrooms, if any, are available for use
  • Where available power outlets are located
  • Who, if anyone, will be home during construction (including pets)

#10 “How will you clean up at the end of the day?”

A quality contractor will make sure that end-of-day clean-up is always taken care of by his crew, whether the project lasts one day or spans several weeks. Establish that he will remove trash, and understand where he’ll dispose it. Also make sure he’ll pick up stray items like nails from floors and outdoor areas, and wipe down surfaces that have gotten dusty during construction, at the end of every work day.

#11 “How and where will tools and materials be stored if the job spans multiple days?”

Part of keeping a clean, clutter-free workspace once the team has left for the day includes putting tools away. If they have large pieces of equipment they plan on storing in your home every evening, be sure to discuss where they’re kept and how they’re transported. (You probably don’t want heavy items dragged across your hardwood floors on their way to the garage.)

#12 “What steps will you take to protect my property?”

This may be one of the toughest questions to ask your contractor simply for the fact that it may seem disrespectful. However, it’s an important one that you’ll need to ask in advance of construction. You may need to also make sure contractors understand your HOA’s guidelines.

Generally, your contractor should be willing to take reasonable measures to protect your property, so be sure to ask what specifically he’ll do:

  • Will you use tarps to cover large furniture items and surfaces in work areas?
  • Will crew members wear shoe coverings when they enter my home?
  • Will you recommend items that I should move to other areas of my home to protect them from damage?
  • Will you close or lock doors as necessary when entering and leaving my home?

#13 “How will additional charges be dealt with?”

Thanks to technology advancements, contractors are able to give more accurate pricing than ever before.

For example, Bill Hippard, owner of Mid America Metal Roofing in St. Louis, uses to provide his clients high-quality project presentations using the app’s measurement feature, which utilizes satellite data for accuracy in projects like scoping and pricing a new roof or repairing a roof.

“It allows me to easily estimate a roofing job and provide a professional presentation to the homeowner,” he said.

Still, home improvement can be unpredictable at times, and once a project is underway, it’s possible that circumstances will arise that change the initial estimated price. Sometimes it’s because you want to update the plans. In that case, it’s helpful to know how to write a change order.

No matter the reason, it’s critical that your contractor assures you that he won’t spend a penny over your agreed-upon budget without first gaining your approval — and if you hire him, this should also be specified in your contract.

#14 “Is there a warranty for your service or for the materials you’ll be using?”

Most contractors offer a warranty or guarantee on their work, and it’s important to know ahead of time what it covers and how long it will remain in effect. Additionally, the materials used on your home may have a manufacturer’s warranty, and you should request a copy of this information before construction begins.

#15 “How do we resolve any disagreements?”

This is a crucial question because, unfortunately, mistakes and disagreements do sometimes occur, despite the best intentions of contractors and homeowners. Asking a contractor how he handles disputes tells you that he has a process for taking care of situations in which clients aren’t fully satisfied.

“Little issues do come up,” Craig Gouker, Manager of Craig Gouker Roofing in Pittsburgh, said. “If you can, research how problems were handled and how the customer felt after it was resolved.”

If your contractor admits to previous disputes, this isn’t necessarily a red flag – so long as he handled the situation professionally.

“When disputes happen, give the contractor the opportunity to fix it,” suggested Kelly.

This may seem like a hefty list, but it’s key to have good communication between contractors and homeowners. You should also be prepared for contractors to have their own list of questions to ask you.

“A contractor that asks questions is trying to uncover what you really want, but one that just nods and agrees with anything you say is not. They’re not really diagnosing the problem and getting to the heart of what you need,” Ariel Istueta, Director of Marketing for Istueta Roofing in Miami, said.

An open dialogue helps ensure that both parties are staying on top of the project, and are setting clear and reasonable expectations of how the project will go.

“Customers and contractors both have to be fair with one another, and your expectations have to be realistic,” Gouker noted.

At the end of the day, it’s in the contractor’s best interest to be honest and trustworthy because he wants you to recommend him to other potential clients.

“We go to market by having raving fans and having customers that glow about us,” Hall said. “To be stable, you need repeat business from customers. Happy customers provide that.”

  1. Darlyne Lawson-Hargis, July 4:

    This is my first visit to your site. I am just getting started, buying a new (to me) home. So I have some contracting in my future! You’re not first site but just had to tell you how impressed I was! I especially love the little tips and the articles of interest you have included. I have found so much of use! Thanks

  2. Harper Campbell, October 4:

    My husband and I are in the process of beginning our first home being built and I am wanting to make sure that we find a contractor that will help us get what we want. It’s good to know that when it comes to asking the right questions that one thing we need to inquire about is what the payment schedule will be like. This is something that will be good for us to know so that we will be able to make sure our budget is able to match it and know how much of it is due at certain times.

  3. Not only is it their specialization, you’ll be prone to have work done well, inside a
    timely manner. You mightt also check their license status and complaints
    with all the State Contrator Licensure and Rgulatory Commidsion along with your
    Better Business Bureau (BBB). According to the manufacturer, Listello panels can bee inmstalled
    (glued) directly over existing ceramic tile.

    Great article, totally what I wanted to find.

  4. Ethan, April 25:

    First and foremost always make sure to conduct a thorough research, by consulting with your peers, friends and family with, look at sites like BBB where people usually provide feed-backs and reviews for construction projects. Make sure you check their license and previous project success rate. Furthermore, before you finally proceed with hiring a contractor make sure that you get the project estimates and work schedule to avoid any confusion during the project.

  5. Hi there!

    These questions will help a lot of client to choose the right contractor for them. This will also serve as a guide if they are dealing with a professional or a reliable contractor. I also agree with Ethan, to research about the contractor, how their previous client rates them and to also check the feedback. Word of mouth is another tool to know if a contractor do their jobs well.
