"We recently had the chance to work with Quartz construction ( owner: Ohad) on our construction project for bathroom remodeling and we couldn’t be more pleased with the results. From start to finish, their team demonstrated professionalism, transparency. They maintained clear communication throughout the project, kept us informed of progress and any potential changes, and delivered everything on time and within budget. The quality of the workmanship is outstanding — every detail was handled with care and precision. What stood out most was their commitment to customer satisfaction. They were responsive to our questions, respectful of our space, and ensured that the final outcome matched our vision perfectly. If you're looking for a reliable, skilled, and trustworthy construction contractor, I wholeheartedly recommend Quartz Construction, Ohad and his team. AJ "

"We want to add to our earlier review. Carnhill Construction has been our go to for the past 6 years. They have dealt with a stone deck that kept leaking refuse down the facade, painted our entire house inside and out more than once, had our wood floors sanded and refinished, repaired cracks and leaks in the siding of the house, repaired a balcony. They have been very creative and innovative in coming up with fixes. As we stated earlier they are professional, reliable, consistent and their communication is immediate. We rely on them to deal with any house repair we need. They are a pleasure to work with. We would recommend them highly to anyone needing any house repairs whether a small or extensive project. "

"Just finished a full kitchen remodel with Unique Home Design & Remodeling, and if I could give more than 5 stars, I would. Working with Tal made all the difference — he was honest, organized, and clearly experienced. This was our first big home project, so we were nervous, but Tal’s steady communication and willingness to walk us through every choice really made us feel confident. The team was respectful, clean, and worked incredibly hard. One thing that stood out was their flexibility — when we made a few changes mid-project, they didn’t roll their eyes or nickel-and-dime us. Instead, they adapted and kept things moving forward. The result is a beautiful, functional kitchen that feels us. Highly recommend these guys if you want quality and peace of mind!"

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