"OT Bay Builders did an incredible job transforming our backyard into a beautiful and functional space! From lush greenery to a stunning patio and water feature, every element was carefully designed and executed to perfection. Their team was professional, knowledgeable, and always willing to answer our questions. They completed the project on time and within budget, and we couldn?t be happier with the results. Our outdoor space is now the perfect place for relaxing and entertaining. Highly recommend their landscaping services!"

"My wife and I chose ON Design&Remodeling to work on our kitchen and we are thrilled with the results. It all started when my wife and I agreed that we need more space in our kitchen. My wife searched for a contractor online, she really liked one of the kitchen design at ON Design&Remodeling portfolio so we decided to call and schedule a visit. Aviv came out within few days and the meeting with him was great- he helped us to think out of the box and explored the options of new floor plan, so weâ d gain more counter space. He was knowledgeable and productive, taking notes and provided a lot of suggestions so we hired him. When they started construction the team had arrived on time, worked very efficiently and clean, Raz the project manager communicated with us daily. They were able to compete the renovation in 8 weeks, within the timeframe we have received. The result exceeded our expectations and has made our kitchen larger and more functional, as we initially wished. A great team to work with. Highly recommended!"

"Had him rebuild an old patio cover in my yard. All we kept were the posts and two beams. Replaced all else. Came out very nice. Couple months later had him do some porch railing and window sill repairs on a rental house my mother owns. Nice work, very fair price. Will definitely use him again."

"Our goal was to build a structurally safe garage storage loft. Juan and Julian were a great team to work with. They were very professional and organized- they gave us a quote and clearly communicated what the plan would look like from beginning to end. They guided us on the items that we needed to buy prior to starting the work in order to complete the project within the estimated time. They suggested modifications that were minor fixes but made the layout make more sense in terms of placement. Their crew finished a day ahead of schedule. They kept a clean work site and the quality of the results were great. I would gladly work with them on another home project in the future!"

"We had an excellent end-to-end experience with IBuilders Design and Build. We hired them for our addition to our home plus other interior remodeling. Let me start off by saying we love the new addition to our home and couldn't be happier with the results. Alan guided us throughout the process of planning, designing and choosing the right materials. Overall all promises and deadlines have exceeded our expectations. I'm very grateful and thankful for all their help and quality work. Will definitely reach out again for future projects I already have in mind. Highly recommended!"

"After they redid our counter tops and island, we had them paint out cabinets and build shelves up to the ceiling. The communication was on point this time and the results speak for themselves. Would definitely recommend them to anyone for any home project."

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.
