"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.

"We are working with Guy to convert our garage into an ADU/pool house and it is going great. I'm always impressed by the quality of work that Guy and his team at Supreme demonstrate -- and very pleased that they are able to live up to the timeline that he commits to. They are able to work well and quickly, and at a fair price. This is a big project for us, but Guy has walked us through each step so we know what we need to do. This is the second time we have worked with Guy and he has delivered well on both projects he has worked on with us. If you're looking for someone to take care of a remodeling job for you, I would strongly recommend Guy."

"Our kitchen was in dire need of upgrades, and we met with many different contractors for estimates. Young from New Life Construction left the best impression by far, from his professionalism, renovation ideas and design, reasonable pricing, etc. I am so glad we decided to go with New Life as Young and his entire team were a delight to work with from start to finish. We received very helpful opinions regarding many aspects of the design and materials without it being overbearing, and it was helpful to see his previous projects through instagram (@newlife_construction) to see what has worked well for similar kitchens in the past. There was clear communication about everything from details of the job to scheduling and everyone was very attentive to our needs throughout. This company handled the demolition, cleanup, cabinets, countertops, overhead lighting, painting, appliance installation (range/oven and dishwasher), sink and faucet installation for us-- pretty much everything in the kitchen except the floors. They bring in separate contractors that are specialists in their respective field (cabinets, countertop, etc) to do each portion of the project so you know you're truly getting the experts at every step of the way. Even after the project was done, Young went above and beyond to wrap up last-minute issues that came up from cabinet parts that were on backorder and to this day is responsive to any issues that may come up in the future. My family and I are so happy with how the kitchen turned out and we would not hesitate to hire Young and his team again for future projects."

"We want to start off by thanking everyone involved in the initial sales process. Kobi and his team were strategic thinkers in that they advised our vision be brought to life visually first. Out of the gate we were able to virtually see what our remodel would look like and that feeling of comfort sells itself. Kobi is very experienced in the industry and was able to guide us through many of our millions of questions with ease. We definitely appreciated having Kobi be able to tell us right from wrong and the end results speak for itself.  We couldn’t be happier with our experience throughout, communications along the way and the end result. We will be spending many a night in our new backyard enjoying the vision we all had and achieved with Home Renew 360s efforts. Our next new home build will be 100% Kobi! Thank you!"

"Jorge, Andy and their team at A1-Builders were knowledgeable, honest, reliable and above all always available to answer any questions we had. They helped build a 2 bed 1 bath 600sqft addition to our home during the lean months over the pandemic. We had multiple projects (pool, patio, retaining wall) going on at the same time with other contractors and the crew from A1-Builders were by far the most professional. They always made sure that they left their work site clean after each dayâ s work. Jorge will definitely be the first person I call for our next home project because I know that even if he does not have the time to do the work, he will always guide me in the right direction. Thank you again to the entire A1-Builder team!"

"Skyline construction did an excellent job. Juan Munoz was a great contractor. We wanted to build an ADU but didn’t know who to trust. The workers were neat and careful. Every worker treated us with respect and we’re very friendly. I would highly recommend them to any of my friends or family."

FAQs for addition to existing structure building service projects in Diamond Bar, 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.
