"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!"

"It was a great pleasure working with Pouria and Juan. I hired them to help build a 400 sq. ft. deck, and they were able to finish it within a week at a very high quality. They were incredibly flexible with all of our requirements?don't hesitate to communicate with them if you need anything changed during construction! They are absolutely amazing and efficient. They even did some extra work around our house, which will really help us in the long run. Their pricing is very fair compared to many other groups, and I will definitely go to them the next time I need a project done!"

"Zacharias Remodeling Construction did an outstanding job remodeling my mom‘s kitchen in July 2025. Oscar, the contractor, was professional, responsive, and easy to work with from start to finish. His team was meticulous with every detail and always arrived on time which made the entire process, smooth and stress-free. This was especially important to me as I had experienced a contracting company in the past where the workers did not show up on time (or at all), cut corners, and it made for a lousy 2 months. The finished kitchen looks beautiful and without hesitation, Zacarias remodeling construction will be my first call for future projects."

"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$) and paint (about 40$)."

"After meeting with around 10 contractors, I decided to go with EA Homebuilders. Eric seemed honest and willing to do our remodeling the way we wanted it done. Great decision. Eric, Hector and crew were courteous and finished the job in the time they said it would be done, less than a month. We love our new bath/ shower. Highly recommend and would use again."

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