"Axe Construction is the real deal. From start to finish, they handled everything—helping us find the right property, managing the full demo, collaborating on the design of a brand-new home, and executing the entire build. What’s impressive is that they delivered all of this within a 13-month timeframe, which is almost unheard of for a ground-up custom build. Communication was clear, decisions were practical, and the team stayed solution-oriented the entire time. No endless excuses, no finger-pointing—just progress. They understand design, construction, budgets, and timelines, and they know how to keep a project moving without sacrificing quality. The final result exceeded our expectations. The house is beautifully built, thoughtfully designed, and feels solid in every detail. If you’re looking for a contractor who can truly handle a project end-to-end—and actually deliver—Axe Construction is the team you want. Highly recommend."

"When I found IND Construction and decided to move forward with them, I felt at ease. Every single step, from design to architecture to clearing out an old shed, to building the structure and final touches, was done with care. That meant a lot to me and my dad, especially now, with COVID-19. The workers were thoughtful and all my questions were answered and attended to. At the end of the day, I was really thankful that my guesthouse was built. It gave me a sense of relief and accomplishment. When I look at it, I think of my mom, who had wanted to build a guesthouse. I think she would have been really happy."

"Avi from So Cal Builders & Design Inc was our general contractor for our house's addition/expansion. This is the 2nd time we worked with Avi and his team, after he helped us completely remodeled our existing house, we know he is the perfect guy for our phase II of building the addition to our house. Again, Avi is so great to work with! He is very knowledgable on all construction related work and he is always available to help with whatever. He is able to come up with super creative solutions for all our requests/wants, we couldn't be happier with the work from So Cal Builders & Design Inc! My city is pretty strict come to all different types of code, Avi was amazing at managing all the city requests for us, I am glad that he helped with all that stuff for us so we didn't have to worry about anything. The work itself is truly awesome, and Avi and his team are here for us even when the work is completed when we need anything. I completely trust Avi and will for sure recommend him to anyone!"
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.

"I found Supreme Remodeling here on Angi. I interviewed several contractors and chose them mostly because of YOAV their representative I met with. He was the only one who offered design ideas at the initial meeting. I wanted to build an ADU. They handled everything from design to permits. As an added bonus their bid was the lowest by quite a bit.😁😁 I would 1000% recommend Supreme Remodeling and especially Yoav, he’s a real gem."

"My husband and I really enjoyed working with Ben and his team at Creative Home Remodeling Group. Ben oversaw everything from making the plans, getting them approved by the city, scheduling the entire build and doing all final inspections. We really appreciate how communicative Ben was with what day and a time window we could expect the different work groups to come and what work would be done those days. If my husband or I ever had questions or problems with anything that was going on during our construction we were encouraged to call Ben and he helped create a solution that was workable for all of us. We liked that Ben and his team took care of everything from beginning to end and we did not have to hire any additional contractors along the way. We did have to purchase the specific fixtures and tiling we wanted.) We added apx 200 sq feet to our home, which included a bathroom, walk-in closet and room extension. The total process took exactly 1 year from signing our contract to us being able to use our added rooms. (That included making the plans, getting them approved by the city, the build, the installation and final walkthrough with the city inspector.) I would recommend using Ben and his team at Creative Home Remodeling Group to my family and friends. We look forward to working with Ben again in the future."

"The KN Remodeling team did an excellent job at our home completely remodeling 3 bathrooms, painting our entire home and rebuilding a huge planter outside. We trusted them in our home while we are out of town almost the entire time. We hired them back to do additional work in our home that they did quickly and expertly. The team was professional, very friendly, worked quickly, quietly, cleanly, and I would highly recommend them. "

"We needed to do a kitchen remodel for a while now so we did a massive research online and by asking friends and family in our area. After meeting with all of them and explaining to them what are we looking for, what we want to do and mainly what is our budget. We received estimates from all the contractors that we met and we selected Trig Builders because Yossi was the most competitively priced and the referrals that we got on him and his company were very positive. Yossi and the workers were very easy people to work and to deal with and Yossi designed the kitchen exactly the way we wanted it with some nice additions of things that we didn’t think we will get. His suggestions about the new kitchen layout, where and what materials to buy were very helpful. Also, his advises and recommendation on where to buy the cabinets, lightings, plumbing and appliances saved us a lot of money. The end result of the new kitchen was perfect and one of the things that added a huge plus before we hired them was the warranty that included in the price of the work that they did."

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