"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."

"The attic fan went very well. Troy was able to isolate and seal the flashing issue that was causing our roof leak, however after further investigation, requiring the removal of some siding, we found some more serious structural damage to the studs in the wall. This seemed to be a beyond his expertise as a 1-man job, so we opted to have him stop there and will bring in a construction contractor to make these repairs. We are very pleased with the work Troy did and would not hesitate to contact him again. We are grateful he was dedicated enough to look into the damage further, otherwise we never would have seen the interior damage."

"The project was complicated because we found after demolishing the old bathroom that our plumbing and water heater needed to be replaced which increased scope and timeline. Future Vision was quick to help us problem solve and adjust the plan, and did high quality work so we are very happy with the results."

"As most of us know when we do a remodeling project, it is real hard to find good and honest people to complete your project. Fortunately, I found Leo and Yonathan from SkyTech Builders to help me with remodeling and repairing two of the bathrooms in my family's 4-Plex building. They were very honest, polite and helpful each step of the process from start to finish. The are very patient and suggested materials and design but always thinking about quality and your budget. Overall the experience with Leo and Yonathan was top notch and we were very satisfied with the finished product. We will definitely be using Sky Tech Builders for our future construction projects."

"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."

"Excellent experience. The price was fair, Ofer was very flexible and responsive to what we needed, and his team were punctual, professional, and efficient. When other contractors would take days to respond and provide estimates, Ofer always got back to me in a couple of hours at most. Adding the skylight took only two days, and the only additional cost was for the skylight itself (about 200$) and paint (about 40$)."

"We first heard about Bay Builders from a realtor friend who highly recommended them. We interviewed multiple contractors, all of whom had done nice work, but Bay Builders really stood out right from the beginning. During the proposal process, they came to the house a few times to ensure they captured the full scope of the project. Additionally, we wanted to see their quality of work so Gilad arranged a few site visits and connected us with past clients who all raved about Gilad and his team. It was clear that Bay Builders was the best choice for quality and speed. From the beginning of the process until the end, Bay Builders was exceptional to work with. We had a dedicated project manager, Tomar, who really helped communicate what was happening that week and managed the subs. More importantly, Tomar was such a pleasure to work with. He is very approachable, detailed and diligent. I've heard nightmare stories about other contractors being slow, hard to contact and missing deadlines, but Gilad and Tomar made the entire process stress free and enjoyable! They were great about keeping us informed about what was going on, what decisions needed to be made so that we could stay on schedule. If any issues arose, Gilad and Tomar would always come to the table with a solution and assure us that at the end of the day, they wanted to make sure we were happy. The quality of their work is outstanding and our project finished on time which is rarity given the complexity and change orders associated with our remodel! They have excellent communication skills, are very detail oriented and most importantly, have your best interest at heart. I would highly recommend them. Everyone who has seen the finished product is blown away by the transformation. We are so happy with how our home turned out."

"We just finished to build an ADU in the backyard with ON Design & Remodeling. In the beginning we met Aviv and he guided us with his team along the design process. They helped us to get the permit faster and choosing all the visible materials before starting the work. During the construction we received weekly updates regards the process so we always knew what to expect. We build the unit for my parents and they are so happy with their new small home, and to share the yard together with us. Currently we are in the planning process to remodel our main resident kitchen with ON team, so obviously we are so happy working with this amazing team."

FAQs for addition to existing structure building service projects in Cupertino, 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.
