"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!"

The workers and staff were really professional, polite and easy to work with. I highly recommended BE Home Remodeling and specifically Josh Zack."

"Bear Remodeling did an amazing job on my bathroom remodel. The team was nice, courteous and worked hard to get what I wanted. They paid attention to every detail and made sure the design matched my idea. They also did some interior painting and made the whole room look cohesive and stylish. I was so impressed I asked about adding a room to my house and they gave me some great ideas. If you need a contractor for any remodeling project, call Bear Remodeling!"

"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."

"Our bathroom was outdated and unattractive, so we wanted to hire a professional to help with the design and get the job done right.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."

"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!"

"It was a pleasure to work with Eric, we hired him for a complete backyard renovation which included tree removal, leveling the surface and place pavers and a deck on top. Also built a retaining wall. The work came out very nice in part because of the great design ideas that Eric gave us. The project ran into some unexpected issues that Eric was able to overcome nicely. We were impressed how Eric handled the project and met all the deliverables, also his team was extremely polite an professional. Our backyard now looks like the ones advertised in magazines. All this led us to start a new project with him to replace the cracked driveway with nice new pavers."

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