"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."

"Ultimately the work performed was high quality. When there were small finish issues, the team came back and fixed everything to ensure continuity with our existing home design. The timeline overran a bit, but the workmanship was great"
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.

"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!"

"We hired D2A Construction to build a detached ADU on our lot, and I’m still in shock at how smoothly everything went. Dani was an incredible project manager — responsive, honest, and always willing to take the time to answer our million questions. He kept the entire job running like clockwork, even when we had a few unexpected city inspection delays. His team was fantastic and the craftsmanship was solid across the board. We now have a modern, fully functional unit that we’re planning to rent out. It blends beautifully with the main house, and people can’t believe it’s a new build. If you want a company that actually delivers what they promise, D2A is it!"

"We had a 50+ year old home that had not been touched since it was built. We planned an install to include new tub/shower, toilet & sink/vanity. Unfortunately, the floor in the upstairs bath had been repaired by the previous owner due to an on going (unknown to us) leak. So in addition to the planned remodel, we had to have the sub-floor removed & replaced. Kyle gave us the best bid and was able to easily work around our ever changing schedule. Kyle provided recommendations & measurements for the supplies and we were able to choose and purchase what we preferred. Kyle's crew was professional & polite. Everyday, they worked long hours, cleaned up and would let us know when they would be returning. In addition to that, the work was outstanding and exceeded our expectations! Professional, pleasant, precise, meticulous and beautiful! We have no reservations hiring Kyle Beym Home Improvement for any future remodel project."

"From start to finish, John and his team were amazing. This project included moving walls, rerouting plumbing and drains. The quality of the finished product was amazing. I would definitely work with John again on our next remodeling project."

"We recently completed our home construction project with this company, and the entire experience exceeded our expectations from start to finish. Building a house can be stressful, but their professionalism, transparency, and dedication made the process smooth and enjoyable. From the initial consultation through the final walkthrough, their team demonstrated exceptional craftsmanship and attention to detail. They took the time to understand our vision, offered practical suggestions, and kept us informed at every stage of the build. The project was completed on schedule and within the agreed budget, with no surprises along the way. The quality of work truly stands out. The finishes are flawless, the structure feels solid and well-built, and every detail reflects their commitment to excellence.

"My husband and I wanted to remodel the bathroom off the master bedroom in our 2 bedroom condo. We got theee quotes and Home Renew 360 was the most affordable without being so low that it makes you wonder about quality. We worked with Nathan as our Project Manager and he was extremely responsive, helpful and professional. At this be point something came up that was unexpected due to our building being older and Nathan explained the issue and gave me a quote before any work was done. At another point something came up a few weeks after the project was completed and Nathan had someone out to fix it the next day. The crew that did the work was polite, clean, on time and professional. The only thing I would do differently is paying for the 3d design. Being that this was my first remodel, I was looking for more of a consultation about what type of materials, colors, etc we should go with and this was more of a 3d image. We ended up meeting with someone at Floor & Decor and he was able to help with the selection of products/materials. I would recommend their services and Nathan for anyone looking to do a remodel."

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.
