"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!"

"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."

"John is the best contractor we have ever worked with due to the scope of his skills/projects and the quality of work and ease of working with him. We have worked with John for over 2 years on a variety of projects (repairing doors and even a 4-poster bed, painting interior walls, trim, ceiling & exterior painting). He meets his commitments and has the highest standards. We fully recommend him."

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.
