    "AES Builder & Home Improvements Inc. was absolutely amazing to work with from start to finish! They remodeled our original kitchen, and the results are beyond beautiful. From our very first meeting to the day we spent picking out custom design materials, the entire process was organized, collaborative, and enjoyable. Their coordination and communication throughout the renovation were top-notch! Every contractor who came into our home was professional, respectful, and genuinely cared about their work. They answered all of our questions and kept us informed every step of the way, even when there were small delays. The quality of the craftsmanship truly shows, and our new custom kitchen makes me smile every single time I walk in to cook. We couldn?t be happier with how everything turned out. If you?re considering a remodel, I can?t recommend AES Builder & Home Improvements enough! Thank you to Stephen, Shawna and the entire AES team!"

    "Joe and his team did an exceptional job helping us integrate multiple projects in our basement and the results were outstanding! We had to have our existing partially finished basement demolished so we could have french drains and a sump system put in, as well as a geothermal heating/cooling installation accomplished, after having an existing oil burning furnace and radiant heating system removed. The basement restoral project included plumbing and sink replacement, electrical and lighting efficiency upgrades, framing and drywall replacement, door replacements, flooring replacement, and a few decorative additions to give the space some character. The entire process: scoping, design, coordination, execution, and detailed wrap up was accomplished under a great leader and problem solver with highly credible and expert tradesman. We shopped around for multiple quotes before selecting JD Michael Construction. Any and all future projects will go through this team! We are grateful!"

    "A&N have been wonderful! They did a great job on the bathroom remodel I needed done on a typical cramped 1950s style bathroom to make room for my mother with her walker. They were able to create so much more space and put in a beautiful walk in shower that works perfectly!"

    "I scored! I originally hired them to spruce up an upstairs apartment for rental- rental ( paint, one room rewalled.) . I told them of future dreams when funds allowed. They worked with me and made the dreams come true immediately. With even more perks. Excellent vision, decorating skills and quality work . Jennifer, their project manager, was on site often to make sure everything was done well. Even beyond my OCD . Small business owned and operated by Jim Davis (a Brad Pit lookalike🤪.) With earned my trust immediately . Will definitely hire again."

    "D&R Improvements did a beautiful job on my bathrooms. David, the owner, was quick to give me an estimate and always responded to my e-mails the same day I sent them, even if it was on a weekend. He scheduled the tile installlation on a Friday and had a plumber come out on a Sunday to reinstall the toilets so that we wouldn't have to spend any extra time without them. Everyone who did work on the house was very professional and nice. They even worked with my three child gates rather than make me take them down. All of this at a very reasonable price. I love my remodeled bathrooms and I highly recommend D&R Improvements!"

Frequently asked questions

  • It’s important that you verify their license is still in good standing. Also keep in mind that certain states or provinces don’t require licensing if the job is under a certain dollar amount.
  • You can find a list of your state’s licensing requirements on the HomeAdvisor website. Before you get to work with the pro, make sure their qualifications are current and acceptable to you.
  • It is always a good idea to get a copy of the pro’s insurance certificate for future records, and in case anything happens. This is a good way to feel more secure in your home project, and to weed out potential scammers.

HomeAdvisor makes it easy to connect with pros near you. You can read reviews, get quotes and book appointments all in one place.

Depending on the type of project, you may find subtle differences in the hiring process. Here’s a look at task-specific advice.

You can use HomeAdvisor to help evaluate a contractor’s qualifications. We put pros through a screening process, and award badges to high-performing contractors. You can find these badges on a pro’s HomeAdvisor profile, and sometimes, his or her website. 

Your research doesn’t stop here. Once you’ve found a few prospective companies, make an call to ask a few questions about work history, licensure and more:

  • Have you completed a job like this before?
  • Do you have a list of references I can contact?
  • When are you able to start the job?

In most cases, the responses you get to these three questions will give you a very good idea of the right pro for your project. If you have more than one front-runner, these additional questions can help you narrow it down. 

  • How many years of experience do you have?
  • What’s your permanent business address?
  • Are you licensed to work in my area?
  • When did you earn your business license?
  • How do you handle warranty service complaints?
  • Do you have worker’s compensation, property damage and personal liability insurance?

Any good contractor will answer these questions, and most will appreciate dealing with a client that takes such an active interest in finding good service. On the other hand, if a contractor gives you a hard time with these questions, you probably want to find someone else.
