"Abraham and his team were awesome. They help us remodel our kitchen and bathroom, and did a great job. We met with several companies before starting our project, but decided to go with My Construction Group because of the great communication and clear cost structure. Abraham really went above and beyond for us! I would highly recommend them to my family and friends."

"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."

"I wanted to share my extreme pleasure with ON Design & Remodeling after that they gave a new look to our full house. The results have exceeded my expectations, and a big part of that credit goes to my project manager, Raz. He made the project successful by being really good at it and paying close attention to every little detail. I'm looking forward to enjoying my 'new' home. Many thanks!"

"Back for round two with Zacarias Remodeling! After they did a fantastic job on my bathroom in 2022, I reached out to Oscar again last week to modify my countertop for a new stovetop. Even for this smaller project, the response was immediate. The crew was professional, conscientious, and the finish is perfect. It’s rare to find a contractor who provides the same high level of service for a quick modification as they do for a full remodel. Still my go-to recommendation!"

"Sol was the Unique Home Design & Remodeling project manager for the recent kitchen and bathroom renovation that we recently did and his team of skilled and hardworking did a wonderful job. We greatly recommend Unique Home Design & Remodeling and mainly Sol, The working crew and the office staff that was involved in our project and we will hire them again for any additional remodeling project in our house. Sol was the project manager on both remodeling projects (kitchen and bathroom), did a perfect designing job for the kitchen space by using most of the existing space with features that we needed and wanted for a while now. From start to end, the extra attention that Sol put to all the details of both projects was more than what we were looking for. He always gave wonderful ideas and suggestions and he made sure that we are happy with all the decisions about both renovations. We love both projects very much! The kitchen and the bathroom got a completely brand new look and they are very functional for our needs. It makes us very happy each time any of us walk into any of them!"

"I went with Sky Tech Builders on a room addition. I decided to hire this company because they gave me very realistic offer, were available in short time and I also got some recommendations from my friends. The project started soon after we signed a contract and it went very smooth, there were no issues or hidden costs. Sky Tech Builders team was professional, efficient, quick and communication was great. They finished this project ahead of schedule, quality is superb and final product is excellent. I couldn't ask for more! Thank you!"

"Our experience with Build The Bay on our bathroom remodel project was exceptional from start to finish. The scope of this project consisted of a complete remodel of 2 bathrooms at the same time. Our expectation and the general consensus with any remodel project is that it will be a very stressful experience as the inevitable hidden issues will be discovered leading to additional costs and our project was no exception. The communication with and received from Eitan and the Build The Bay team starting with the bidding process and ending with the final inspection went a long way to reducing our stress level throughout the project. The plan was clearly communicated on a daily basis and every problem encountered came with a proposed solution with an emphasis on minimal cost impact to our budget. The daily planning and communication gave us confidence in their experience and ability to manage the entire project no matter what issue came up. This was evident from the first day taking care to mask walls & floors in order to protect every potential area that could be impacted by construction collateral damage. It was also evident that the work crew had the necessary skills to complete the many varied tasks the project required including framing, sheetrock, electrical, plumbing, tile, floors, windows, texture, paint, as well as the installation of the vanities and all of the additional finishes. The Project Manager Jesus and the entire crew were considerate of our living space and all were professional and friendly throughout the process. Upon completion of the project a deep cleaning was performed and the only evidence that remains of the entire 4 week process are 2 absolutely beautiful bathrooms constructed by Build The Bay!"

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.
