"Pristine did an excellent job on our kitchen remodel. The work included new cabinets, flooring, counters and backsplash. The owners, Nathan and Mike were very "hands on." Everyday, one or both came by to co-ordinate with their workers. They had very good attention to detail. All of the work performed was done in a professional manner. We would definitely use them for any remodel."

"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.

"We just finished a four bedroom/ three bathroom full remodel in Santa Monica. We are very happy with the end result. Nathan, who is the owner, was very involved in all phases of the job. Nathan got the job done on time. The workmanship and attention to detail was great. He had good communication and relationship with his team. Whenever we had a concern or question, Nathan was easy to get a hold of and handled it quickly. We were worried about the process of a remodel with all the stories you hear about bad experiences. But Nathan made this so easy on us and we would definitely use him for any future projects."

"If you need an addition built on your house, I'd highly recommend you give Creative Remodeling a call. We used them to add a master suite which makes our house much more livable. We've also decided to add decking in the back yard off the the back of the house. Oh, and this was after working with them during Covid on a kitchen and 2 bathrooms. So that makes us repeat, on repeat, on repeat customers. The work is quick, to a good quality, and they listen to what the customer wants and have dealt with the odd snafu without any push back. Highly recommended."

"We are thrilled with Axe Construction! From their initial bid and our first meeting we felt Tomer was honest and transparent and he continued to prove us right throughout the entire build of our ADU. The AXE team is efficient and detail oriented. They deliver what they promise. Our foreman, Enrique, was on top of it. He would visit the site daily to make sure everything was running smoothly and on schedule. Both Tomer and Enrique were easy to get a hold of and quick to stop by if we needed to discuss anything in person. 5 stars, A++."

Customers say: True professional

"H&A MY Design made building our garage an effortless and enjoyable process! From the moment we walked into their incredible 5,000-square-foot showroom, we knew we were in the right hands. The showroom truly is a one-stop shop where we could explore construction materials, finishes, and design ideas all in one place. The team helped us narrow down options that fit both our vision and budget. Their professionalism, attention to detail, and seamless communication were second to none. The construction crew was respectful and clean, completing the job on time without any hassle. I wouldn’t hesitate to recommend them for any home improvement project."

"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 West Hills, 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.
