"Ronald and his team were great. He was the first to give me an estimate and was the only one who went on the roof to inspect it. He gave me an amazing price snd was available if I had questions. His team came early (7am) and worked until the afternoon. I would recommend them to anyone and hope to use them again for more work on my home."

"Jose and his crew did an outstanding job on our extensive interior and exterior renovation, which included a new addition. The project covered everything from a new structural roof with shingles and skylights to new construction windows and doors, siding, a Trex deck, and fully renovated kitchen, bathroom, and laundry room. They also refinished a bedroom and installed beautiful hardwood floors. As with any large project, a few unexpected challenges came up, but Jose handled them with professionalism and kept everything moving forward smoothly. His craftsmanship is excellent, and he’s not only easy to work with but also patient and highly skilled at problem-solving. I wouldn’t hesitate to hire Jose again for future projects and highly recommend him to anyone looking for quality work and a reliable contractor."

The floor, lighting, and granite countertops look beautiful. The construction was done in a timely manner and knowing they have fantastic designs. I would definitely have them come back to help with other projects."

"I cannot say enough wonderful things about Keith Coco and his team! From the very beginning, they listened to my ideas, understood my vision, and then brought it to life in a way that completely exceeded my expectations. They built our gazebo and pool deck, and the craftsmanship, attention to detail, and quality of their work are absolutely incredible. What I had pictured in my mind became even more beautiful than I imagined! Keith and his team were professional, knowledgeable, hardworking, and truly took pride in every detail of the project. It’s not always easy to find a company that delivers exactly what they promise — and then goes beyond it — but they absolutely did. We couldn’t be happier with the finished result. Our backyard has been completely transformed into a space we are going to enjoy with family and friends for years to come. Thank you, Keith Coco and team, for taking my vision and turning it into something even better than I dreamed! I would recommend them without"

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.
