"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!"

"After they redid our counter tops and island, we had them paint out cabinets and build shelves up to the ceiling. The communication was on point this time and the results speak for themselves. Would definitely recommend them to anyone for any home project."

"It was a challenging time to undertake this project between COVID, engineering errors (not the builder), labor shortages, and the price of lumber. I would not say it was easy, but the end result is a very well built, comfortable, attractive, and energy efficient living space. I learned a lot from this project and provided feedback to the contractor about what I didn't know about the process when we began and what others would benefit from. One key item is a clear list of what the "finishing" materials are and a schedule indicating when these materials are needed. I recommend that anyone working on a building project of this intensity insist upon a detailed list as part of the contract and in advance of the work beginning. Since our work was done, this contractor has hired two additional people to focus on those types of needs. The people performing the labor were always polite, friendly and respectful of masking and social distancing. We felt comfortable with them around our home. One thing that could have been better is more orderly disposal of materials and separation of recyclable and non-recyclable items."

"I highly recommend hiring Adrian Kovaci and his crew at Ceres Construction for your home construction project.The quality of their work was superb, the cost was comparible to the three other quotes I got from other companies, and their work presence at my home was unobtrusive as I could hope for. My two level 1923-built Richmond district home in San Francisco had a derelict passage to my garage - crumbling door, wobbly side stairs, and dry-rotted siding. Nothing was up to code. Adrian noted all the items that had to be reconstructed and said the project would take up to 20 days (it actually was finished in 18 days.) Adrian was very accommodating in giving extra finishing touches to my door hallway without extra charges, which I appreciated. I was concerned about the cost of the project and the disruption the work would cause, but Adrian's calm demeanor and the friendliness of the crew put my worries to rest. Thank you Adrian for leaving the work area spotless and for the quality work!"

"We had a great experience working with David and Prosper Construction Development on a large home renovation and kitchen remodel. Prosper was in constant communication with us about our project and the timeline and was very responsive to our many questions, always responding to texts and phone calls in a timely fashion. All the workers from Prosper Construction did top-notch work, including installing a tricky glass subway tile back splash in the kitchen. Prospers prices were extremely reasonable and very competitive compared to the other quotes we received for the same scope of work. I get compliments on my house--especially my new kitchen--from everyone who walks through the door. We originally called Prosper because we had an unexpected set of repairs to make, but we ultimately ended up with a much more comfortable, beautiful, better quality house to live in. We are so glad we went with Prosper Construction and will definitely call them in the future for any additional renovation needs we might have."

"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!"

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