"Where do I start! I am so happy I found a trustworthy and reliable contractor in Walnut Creek. Our house was basically a complete rebuild from a 1941 bungalow. We expanded the existing footprint by more than double and also added a detached garage. S&L was the absolute best! We bought the house in February but were not able to complete the drawings/permit process until a whopping 7 months later-- by which time a substantial amount of our resources were used up by paying rent + mortgage+ storage. The contractor we had planned to use could not fit us into his schedule so we were in a bind-- I found Jacob and contacted him immediately. Everyone he has on his team was courteous, responsible, and just very good at what they do. the craftsmanship that went into our house was much better than many of the new construction track homes we have seen. I only wish we found him sooner--since his business also does the architectural drawings-- we probably could have gotten into our house several months earlier. As I was very nervous about making changes to my home, the team at S&L Remodeling and Design made me feel comfortable and excited with the new renovations. The process was quicker than expected and I now have a beautiful kitchen and bathroom space!"

"Our remodel was done good. Fito the foreman was very easy to work with. Him and his crew were cooperative and helped us with things we needed done. Our project manager was good and he coordinated the other contractors to come out to do the railing and shower door and the deep cleaning for the house after the job was done. We really appreciated that. We want to thank you for everyone’s hard work and their diligence in working on our project. Best Mimi and Alvin Yee"

"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!"

"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

"Cerletti & Kennedy recently renovated our kitchen and dining area, and the end result is exceptional. In addition to relocating HVAC and water heater, our project required structural work. All of these things, as well as our daily questions and concerns, were handled by Matt and Robert et. al. with professionalism and patience."

"We hired Bear Remodeling to convert our garage into an ADU for my mom to live in, and they knocked it out of the park! They handled everything. The team added proper insulation, installed new windows for natural light, and created a small but efficient kitchen area. They even finished the exterior paint to match our house perfectly. The transformation is incredible. You'd never know it used to be a garage. It took about 8 weeks from start to finish, which was actually faster than we expected. If you need more living space but don't want to move, I'd recommend their garage conversion service without hesitation."

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