"Our experience with R And B Master CONSTRUCTION . began with a backyard ADU project in Mountain View. The team helped maximize storage and natural light, while they used energy-efficient windows and durable finishes. The finished ADU is comfortable and rental-ready, and they solved limited site-access constraints. Construction followed the planned phases. We always knew what was happening and what came next. We are very happy with how everything came together and would recommend the team."

"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!"

"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."

"Idan and the crew from Bear Remodeling were professional from the beginning to the end of the 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.
