"The contractor completed all work with care and on schedule. He communicated clearly and in a timely way— with excellent results in every aspect of this 3-month job. . His crew was skilled, experienced, well-manned and well-coordinated—from the senior electrician, with his team, to the painters. In addition, attention to every detail and to overall scope of work was flawless— and yielded beautiful results. The contractor was both flexible and decisive, efficient and knowledgeable about every aspect of the project. He met deadlines, was responsive to all concerns and requests; reviewed progress daily over many weeks; integrated change orders smoothly; and resolved problems completely. As the client, I am completely satisfied and recommend him highly. I would hire this contractor again in future, with full confidence in his integrity and expertise."

"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!"

"If you’re thinking about getting a new roof, definitely go with Build Atlas. I’m in my mid-20s and had no idea where to even start, but a neighbor recommended them and I’m so glad that they did! The whole team was super friendly, down-to-earth, and made the entire process way less stressful than I imagined. They showed up when they said they would, kept everything clean, and finished faster than I expected. Plus, the roof looks fantastic — it’s like my house got a facelift! It’s rare to find a company that’s this easy to work with!"

"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."

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