"Great! Excellent communication from the project manager, work crew went out of their way to do a great job and to pick up materials for me when delivery wasn't possible. They were punctual, cleaned up at the end of each day, tried to minimize the intrusion as much possible, and were really nice guys, great to work with. Work was done on time and on budget. Kitchen looks great and I couldn't be happier. The price was for labor and raw materials. We supplied the cabinets, lighting, countertops, sink, appliances, and windows. We also decided to get the attic insulated at the same time at their suggestion- that addition was not included in the cost below (I don't remember how much it was but it was reasonable.) Here's what the work included: Demo existing kitchen including walls, floor, ceiling and windows. New electrical sub panel and wiring in kitchen Gas line added to kitchen (gas was already in the basement area) Installation of new walls, floors, ceiling, windows, doors, trim Installation of cabinets, countertops, appliances, sink Painting Attic insulation (additional)"

"Our bathroom was outdated and unattractive, so we wanted to hire a professional to help with the design and get the job done right. We found Builders Group on Angie, and Mike came out to give us a quote. What set Mike apart from the others was his attention to detail and how great he was with people. We decided to hire him, and we were happy with our choice from the very beginning."

"It went well. There were some surprises. Damaged shingles and structural damage were discovered once we were underway. This lengthened the duration and cost of the project. Fortunately Sigura has carpentry capabilities in addition to their painting skills and were able to make the needed repairs before resuming the painting. The rest went without a hitch."

"I had a second storey addition completed by Rose Remodeling, and the results are truly amazing. The team did an outstanding job blending the new structure seamlessly with the existing architecture so that it looks like it was always part of the house. Adir guided us through every step, answered all of our questions, and kept the process stress-free. We now have the extra space we needed, and the work exceeded all of our expectations. Highly recommend their services."

Customers say: True professional

"We found McCormick home builders through Angie’s list. They were not one of our original contacts, but they contacted us and came out to give us a quote. Matteo was extremely helpful, informative, honest, and gave us reasonable realistic prices, and did not try to inflate the prices or pressure us in anyway. We felt very comfortable with him immediately. We felt like he was a member of the family that we could just talk to and ask questions he was very personable. He gave us his contact number in case we had other questions and he was always available when we needed him for any type of questions or concerns. Mateo‘s team did a beautiful job. They were fast. They were efficient. They cleaned up beautifully. They did a wonderful job. They were very considerate of our time our needs and our neighbors. They were an absolute pleasure to work with. I would highly recommend Matteo from McCormick home builders for any home building projects, and we will be calling him again in the future!"

FAQs for addition to existing structure building service projects in South 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.
