"Gabriel and the team at American Family Construction were fantastic to work with. They helped us transform our outdated kitchen into a modern, functional space. The attention to detail was second to none—Gabriel was always available to answer our questions and offered great suggestions to enhance the design. The remodel was completed on time, and the craftsmanship was top-notch. The price was reasonable, and we never felt like we were being upsold on unnecessary items. I’d recommend them to anyone looking for a reliable, high-quality kitchen remodel!"

"Ben helped us convert our VERY old garage (80+ years) into a modern multipurpose room. He was communicative throughout the process, friendly to work with, and the final product exceeded our expectations. We highly recommend YB Builders to anyone looking for a contractor."

"We had ACE Construction out to completely remodel our bathrooms in our 1909 farmhouse. We tore down walls and moved everything around because we didn’t like how the bathrooms were originally set up. They helped design the layout and helped pick materials. It was an amazing experience. All the workers showed up when they said they would and were very respectful. I would definitely use ACE on our next project and recommend to everyone!"

"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!"

"It’s hard to find an expert contractor that is also honest. John ensures his team produces high quality work. He’s there everyday to make sure it’s done right. The job was done expeditiously despite that his team was in high demand. It was much less stressful for us with his process to get everything delivered before the actual construction began. We love our new area so much that we hired him for our two bathrooms upstairs next."

FAQs for addition to existing structure building service projects in Corona Del Mar, 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.
