"We had been putting off our room addition for years, worried about the hassle, cost, and finding the right contractor. Thankfully, we found American Family Construction & Remodeling, and they made everything so much easier than we expected! Gabriel was incredibly communicative throughout the entire process, keeping us updated on progress and ensuring we were happy with every step. The crew was efficient, respectful, and left the site clean every day. Now, we have a beautiful, functional new space that adds so much value to our home. If you're looking for quality work with zero stress, this is the company to hire."

"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 contacted Angie's List for our roofing needs. Set an appointment and met with "Erik" Gombinski, Supervisor. My wife and I mentioned to Erik what & why it was our desire to do the demo. After and with additional information, Erik stated, hold off (our house is for sale) and for all the right reasons wait to see what/if a buyer would want to do. The decision was "right" and the overall idea was not to spend our $$ unnecessarily, but to see what is coming up. Erik was not only a great representative of Home Renew 360 BUT a true professional in estimating what is truly all end. Would/Will use Erik and Home Renew 360 on any/all our needs on our next purchase with WHAT WE KNOW TODAY, total peace of mind on the quality, concern, and representation? Thank you Erik, Audrea & Jim Langdon, Santa Ana, Ca."

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!"

"I had a really good experience working with Manifest Construction. Joshua was our main contractor, and he was very professional, easy to communicate with, and great to work with throughout the project. What I appreciated most about Joshua was how flexible and accommodating he was, especially when it came to change orders. Anyone who has gone through construction knows that things don’t always go exactly as planned, but Joshua always did his best to make things work. He was patient, listened to what we wanted, and helped find solutions instead of making things complicated. He made the whole process a lot less stressful, and I really appreciated his positive attitude and willingness to work with us. Overall, we’re very happy with our experience and would definitely recommend Joshua and Manifest Construction to anyone looking for a reliable and easygoing contractor. We would absolutely work with him again!"

FAQs for addition to existing structure building service projects in Newport Coast, 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.
