    "Jorge did an outstanding job remodeling both of our bathrooms and replacing all of the water pipes throughout our house. The quality of his work was excellent, and everything was completed professionally with great attention to detail. Jorge is reliable, trustworthy, and extremely responsive. He kept us informed throughout the project, addressed our questions promptly, and always followed through on his commitments. He is someone you can truly trust to do the job right. On top of that, he went above and beyond by replacing a few additional items at no extra charge, including our kitchen sink and several shutoff valves. Those thoughtful extras showed that he genuinely cares about his customers rather than just finishing the job."

    "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!"

    "For our bathroom renovation in Belmont, we chose R B Master Construction. The project manager answered questions quickly, and throughout the process they coordinated plumbing and final inspections. They used quality waterproofing, tile and fixtures, while the project covered 85 sq. ft. primary bathroom. We feel good about the result and the investment we made. We appreciated the practical communication and the care shown throughout the work. The result speaks for itself, and we would confidently recommend the company."

    "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."

    "Not only did Eddie and Yesenia take care of our framing they also assisted us with finish carpentry and complete installation of the cabinetry. We were skeptical to hire them because they are a very new company but once we met them and understood Eddie’s decades of experience and their family oriented business we were very comforted. We also were helping our aging parents make their house comfy and safe to live their remaining years. MW was the only GC that aimed to please and work within our budgets. They also advised and predicted other costs that might arise so we could budget for it. At the end of the day the work was done timely and expertly. I wish the very best for this amazing family. They have truly become friends of mine. I an so grateful for what they have done for our parents. Thank you Eddie, Yesenia, and Lalo!!!!"

Frequently asked questions

  • It’s important that you verify their license is still in good standing. Also keep in mind that certain states or provinces don’t require licensing if the job is under a certain dollar amount.
  • You can find a list of your state’s licensing requirements on the HomeAdvisor website. Before you get to work with the pro, make sure their qualifications are current and acceptable to you.
  • It is always a good idea to get a copy of the pro’s insurance certificate for future records, and in case anything happens. This is a good way to feel more secure in your home project, and to weed out potential scammers.

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:

  • Have you completed a job like this before?
  • Do you have a list of references I can contact?
  • When are you able to start the job?

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. 

  • How many years of experience do you have?
  • What’s your permanent business address?
  • Are you licensed to work in my area?
  • When did you earn your business license?
  • How do you handle warranty service complaints?
  • Do you have worker’s compensation, property damage and personal liability insurance?

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.
