"We could not be happier with the work Peter and Dave did replace our deck. They worked with us every step of the way, offering suggestions as we made tweaks and minor changes in the layout, and Peter was very willing to fit in a couple of add-on projects for us as well. The work site was cleaned up daily leaving the yard spotless. We would definitely recommend Peter to anyone looking for prompt work, attention to detail, and at a very competitive price. We are already talking about having them come back for a smaller project. Thanks, Peter and Dave!"

"Brian and his crew worked very diligently to do what they said they would do and get it done in good time. The painting project took 7 days and they often worked long days. I'm quite happy with how it turned out and would definitely hire them for other projects."

"Torin and Jack were so easy to work with, and they did an excellent job with our basement. It?s clear that Torin is very passionate about his company and the work that they do. We had to re-finish our basement after a pipe burst, and Torin made it easy to meet the requirements of our insurance agency. He provided all of the paperwork we needed in a timely manner, and was able to recreate our previous setup to the satisfaction of the insurance company. We also appreciated Torin and Jack?s flexibility with our schedule. They were very communicative and always let us know when they had openings ahead of our scheduled sessions so that we could continue to make progress on the build. We felt very comfortable with them in our home so often had them come while we were at work. Torin was very easy to work with and we highly recommend his company and will be using them again for future projects. Bonus - Torin and Jack both like dogs, and were super sweet to our pup! She loved having them"

"From start to finish Steve was friendly, professional and had no problem helping us through every step of the process. Steve managed to keep the job site meticulously clean, kept to his promised timeline and was mindful of our budget. He has a great artistic eye and was able to make necessary design changes that took the job to the next level. The fireplace he installed is a STUNNING show piece with a complete shiplap surround, a beautiful handmade wood mantle, custom iron brackets and shiplap that continues across the entire back living room wall. Steve's attention to detail, talent and care for what he does shines through and we couldn't be happier with the end product! We are excited to have him continue our renovation process by remodeling our kitchen and other living space projects. We would highly recommend Steve to anyone we know. We were lucky to find him!"

"Roberto and his crew were amazing! Our house flooded and had to be gutted and within a few hours of reaching out to his company he was onsite and gave me a very reasonable quote. He started just a few days later...on Thanksgiving no less! He and his crew are very hard workers and did an amazing job! I couldn't recommend them more!"

"Jeremy and his crew were great! Personable yet professional. The job took a little longer due to more subfloor damage than expected. The end result… perfection! I will definitely hire ACQ Home Improvement again, and gladly recommend them to my friends and clients."

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:
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.
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.
