"They were reasonably priced, were on time, worked efficiently and quicker than I expected, and cleaned up everything afterwards, making sure there were no nails for my cars, kids, or dogs to find. Great craftsmanship and skill. They also installed a solar light with minimal mess that looks and works well. I would highly recommend them."

"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."

"It was a pleasure to work with Eric, we hired him for a complete backyard renovation which included tree removal, leveling the surface and place pavers and a deck on top. Also built a retaining wall. The work came out very nice in part because of the great design ideas that Eric gave us. The project ran into some unexpected issues that Eric was able to overcome nicely. We were impressed how Eric handled the project and met all the deliverables, also his team was extremely polite an professional. Our backyard now looks like the ones advertised in magazines. All this led us to start a new project with him to replace the cracked driveway with nice new pavers."

"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 Livermore, 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.
