"OC Home Builders remodeled the interior of our home (kitchen, two bathrooms, one laundry room, structural upgrades, fire place) and everyone on their team worked incredibly hard to complete our project. They worked great with city inspectors and have great relationships with them. America and Jim were available whenever we had questions and always gave great value for their work. They were willing to work with other contractors and be flexible to adjust to our schedule. Their entire team takes a lot of pride in their work and they want to make their clients happy. We would definitely recommend to others."

"After several long years of designing and permitting our home remodel during the pandemic, we were searching for a good contractor to build out our remodel and second story addition. Avi and David were wonderful; very thorough in explaining the process, answering all of our questions, and settling on a price that was reasonable and within our budget. During the building process, David was very responsive, available, and receptive to changes and last minute decisions made along the way. The project took longer than anticipated and there were some unexpected setbacks, but David and Avi worked quickly to fix issues and keep the project moving forward. At the end of the project they were very responsible about making sure we were satisfied with every last detail before completing the project. Our new home is beautiful and we're very happy with how it turned out, thanks to David and all the crews at So Cal Builders."
Completely renovating both the guest and master bathrooms. In the master bathroom, we're installing a spacious walk-in shower featuring dual black-finished shower heads, elegant floating benches, and marble wall tiles. Meanwhile, the guest bathroom will have a sleek built-in tub and stylish hexagon tiles.
This project involved adding a new master bathroom to the existing house. The shower features sleek white subway tiles complemented by striking black fixtures and shower door hardware. The bathroom floor is adorned with elegant white marble tiles, providing a seamless and luxurious finish. A white shaker vanity topped with a white marble countertop completes the space, creating a clean and sophisticated look.

"Kyle and his team are great people. Kyle is sincere, kind and knowledgeable in his field. His people came to work every day, never missed. They were on time, and the renovation was delivered as scheduled or earlier. The best thing about this company that they worked at my house until the job was finished. They worked from Monday thru Saturday, approx. 8-10 hours per day. The crew are all experienced, polite, and listened well as work progressed. The cost was reasonable, right on our planned budget. Thanks to Kyle and his men. Thanks to all the hard work, the clean up, the easy, laugh, and fun to talk to guys....the stress of going thru the renovation is now my enjoyment of the new bathroom (conversion from tub to standing shower), and amazing new kitchen. My next project with Kyle will be my new floor. Im looking forward to meeting Kyle and his team again at any time. Definitely Kyle and his company are the one to go to when come to Home Improvement."

"My wood balcony has termites and water damages. So I hired RET to do the job. Kevin gave estimates and recommended composite planks for floor and red woods for railings. His workmanship was very professional and finished on time! On top of that, Kevin updated my balcony to the latest building codes. His price is very reasonable. If you want cheap prices and lousy jobs,hire someone else! Highly recommended!"

"Had our roof replaced by the awesome team with Nathan behind the wheel. Very professional and no hidden costs, upgrades, etc. Very timely and up to standards. I cannot recommend them enough to anybody needing anything. In fact, we will be reaching out for future improvements on our small bungalow in LA. Also, be assured that they are not some "new to the game" company as there are a lot of them."

"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

FAQs for addition to existing structure building service projects in Costa Mesa, 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.
