"We hired OT Bay Builders to remodel our kitchen, and the transformation is beyond what we imagined! Their design team worked closely with us to bring our vision to life, suggesting great ideas while keeping our budget in mind. The craftsmanship is top-notch, and every detail—from the cabinets to the countertops—was executed perfectly. The team was professional, communicative, and always cleaned up after themselves. If you're considering a home remodel, look no further than OT Bay Builders!"

"Karol and his crew are very talented, efficient builders. We hired Karol to build a composite deck to compliment the pool we had installed in the back yard. It turned out beautifully. He is a great communicator and listener, prompt and reliable."

"Tool Time was absolutely fabulous. Extremely professional and thorough. From beginning until end, everything was outstanding. No detail was overlooked. This was a step down for my mother‘s home, she couldn’t be happier. It looks as though it was installed at the same time the other banister was. 100% GREAT JOB !!!"

"It was a great pleasure working with Pouria and Juan. I hired them to help build a 400 sq. ft. deck, and they were able to finish it within a week at a very high quality. They were incredibly flexible with all of our requirements?don't hesitate to communicate with them if you need anything changed during construction! They are absolutely amazing and efficient. They even did some extra work around our house, which will really help us in the long run. Their pricing is very fair compared to many other groups, and I will definitely go to them the next time I need a project done!"

"After I contacted several contractors on a room addition I decided to go with Sky Tech Builders and I can tell that it was a really easy decision because they gave me great offer and they completely understood what I wanted to do. They were also available on acceptable time and project started soon after we signed a contract. The project manager and his crew were professional, honest, helpful and very respectful to me and my home. They finished project within time they promised and within my budget. And final outcome is excellent, I am fully satisfied with everything they did and would definitely work with Sky Tech Builders again!"

"I set off to find a solid contractor who had great reviews and was relatively affordable. I probably looked at over 15 contractors before finding Gili! He stopped by our new place, gave us helpful insight while he looked around, and quickly emailed us a thorough quote with a breakdown of the cost for material and labor. He was the ONLY contractor we met with who bothered to explain all the costs with detail (which were very reasonable). Clever Design and Builds crew got to work quickly, arrived on time every day they were scheduled to work, and cleaned up at the end of the day. They did a complete kitchen remodel, knocked down a wall to open up our living space, and installed gorgeous laminate floors that resembled exactly the kind of hardwood I would have wanted to have but at a more affordable price. They also put down tile and we could not be more thrilled with the results! Roy was our foreman and his team did an absolutely amazing job, the final result is beautiful! Not only was Gili and the entire team absolutely professional and produced stunning results, but they were able to complete the job quickly and adjust any issues that came up so we could get the exact vision we were hoping for! All in all, we could not be happier with Gili, Roy, or their work and we are so glad we decided to go with them! We absolutely will use them in the future for any other projects we have."

"Our bathroom was outdated and unattractive, so we wanted to hire a professional to help with the design and get the job done right. We found Builders Group on Angie, and Mike came out to give us a quote. What set Mike apart from the others was his attention to detail and how great he was with people. We decided to hire him, and we were happy with our choice from the very beginning."

FAQs for addition to existing structure building service projects in Stanford, CA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
