"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!"

"Torin is an incredibly professional contractor. He built custom shelving for my living room, as well as a custom bench. Both came out better than I could have imagined. He asked great questions and really was able to make my vision come to life. I was impressed by his efficiency in finishing these projects while still giving the attention to detail that really wowed me. He will be my go-to for all future contracting needs. He is very reasonably priced, works efficiently and doesnt take forever to finish a job, and does exceptional work."

Expert Kitchen Remodel
"Scott and his son along with their team did a great job. We had an old kitchen with old cabinets and counters. They provided different designs based off of the ideas we had and that helped us decide which one to go with. The designs they provided were great. Also they gave us so many options to choose from as for countertops and cabinets. They gave us a timeline and everything went as expected! They were able to move the sink and dishwasher over onto an island, which freed up space on the other side to add more cabinets and center the stove. We are very happy with the kitchen remodel and will reach out to them everytime we need some work."

"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!"

"Dustin C. @ DaBella Boise helped us choose the right windows for our application and personally monitored progress from order to completion. The finished product looks great, but the best part is instantly seeing and feeling the difference between modern tech vs. 40y old aluminum framed windows. No more drafts or condensation! Thanks DaBella!"

"I recently hired Nick and his crew to paint my upstairs guest bedroom with cathedral ceilings and they did an outstanding job. They also installed over 400 square feet of solid Brazilian Cherry Hardwood Flooring and it came out amazing. I would highly recommend Nick and Company and we will be hiring them again when we need more work done, very polite and professional. Thanks so much for a great job done. Thanks again, Kim & Cindy Doubleday Baptist Road Canterbury, NH"

"We had two projects to tackle: one, we wanted a mural painted on the ceiling of our bathroom, and two, we'd goofed up matching the white color when doing some construction in our bedroom, and the only solution was to repaint the whole thing a new white. Mandy did a BEAUTIFUL job with the ceiling mural and was done in two days; Evin came in on day 2 to take care of the whole bedroom (which is kind of an awkward space since it's a converted attic: most of the walls are slanted and the whole ceiling had to be covered as well). He did a meticulous job and we were so relieved to have it all taken care of so quickly. Meanwhile at the next party we had, we kept overhearing guests talking about how cool the bathroom was and asking for tours; it felt like this fun secret to our house, which is exactly how we'd wanted it."

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.
