"Cal and his team, CJ and Matt, did an incredible job with my deck. The workmanship is great and the design is just what I wanted. Matt and CJ are easy to communicate with, answer all your questions and add suggestions which is always helpful during a construction job. I would highly recommend McCarthy construction and will be using them again in the future."

"I worked with Sean and his team on a large basement renovation as well as a few smaller projects throughout my clientâ s home. I found him to be professional, reliable, respectful and extremely competent in completing the project. We were especially appreciative of how inventive the team was while trying to combat specific issues we ran into. We had a set timeline and everyone did a great job ensuring things were organized and ran according to schedule. I highly recommend Sean and his team for any home renovation project! My client was beyond happy with the service provided."

"Great service, very accommodating company! On site service was great! Make sure if your service includes changing a filter for your central air and heating system. I thought It was included in the service I was getting and for the price I was paying. Wish I had known that earlier to the appointment. Overall, highly recommended company, and I'm very satisfied with the service."

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.
