"I was skeptical of remodeling our kitchen because you hear so many horror stories about contractors taking too long, charging more than they say, flaking out, etc. My husband and I were in disbelief at how OPPOSITE Pristine is from that. Pristine Construction is exceptional. I don't think I have ever encountered a better company.... and I have very high standards! Nathan and Mike are not only true to their word, totally professional, and incredibly knowledgable, but they are 2 great guys who are fun to hang out with! They make you feel like you are their only client. Pristine Construction really does care about you as a person and they take a great deal of pride in providing the best service and best quality work. Also, the designer they had design our new kitchen was incredible. The layout of our finished kitchen is gorgeous. We are extremely happy with everything Pristine and their sub-contractors did. Our kitchen remodel was worth every penny. Their price was reasonable and similar to other construction companies around. Nathan and Mike and their crew helped us better our lives and we are eternally grateful. You will not find anyone better in Los Angeles!"

"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."

"The team at Creative Home Remodeling Group did an amazing job building an ADU for my backyard. Kris was friendly, professional, and incredibly easy to work with. He made the entire process smooth and stress-free, from permitting to completion. Quality of the work was excellent, and we couldn't be happier with the result. We will definitely use them again. Highly recommend!"

"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 hired Ben to remodel our living room and kitchen, which included adding approximately 300 square feet, creating an open floor plan, and removing an enormous brick fireplace in the center of our house. From day one, Ben was amazing to work with. He was on budget, on schedule, professional throughout the entire project, and consistently anticipated potential issues before they became problems. His wealth of experience was incredibly valuable when it came to making decisions along the way, and he was always willing to offer thoughtful advice and guidance. His entire team was fantastic as well: professional, respectful, and clearly committed to doing quality work. We couldn’t be happier with the results and our experience working with Ben. We highly recommend Ben for any remodeling, building, or construction project!"

"Mike Mamen called back within the hour. Next day I showed him the problems with my 90-year-old garage's roof and wiring. He tell me that existing 2x4 rafters could be sistered rather than replaced with 2x12. Additional 2x6 tie beams across garage. He recommended all new shingles, garage door, side door, window, lights, and outlets. Exterior paint on stucco and wood trim. Mike recommended replacing the house 100A electric service panel with 200A, in addition to trenching a conduit between house and garage. He also recommended grading behind the garage to route water away from its foundation. Also, adding gutters and downspouts to both the garage and house. Later we discovered that the house's facia needed to be replaced. He drove me to two current job sites, introduced his crew, and showed the work being done. Mike is knowledgable, direct, friendly, and talkative. Listens to my concerns and ideas, then presents options and his recommendations. Responds to later questions and text messages. Knows local building codes and permitting process. Works by the book -- written contract proposals describe the job and materials. Flexible in handling changes and unexpected glitches. Does minor tasks gratis. Personally attends inspections. Likewise, foreman and electrician Luis is friendly and competent. I am pleased with the competence and results of MF Construction and Design. The entire job took about seven weeks. It was more expensive than I would have thought. OTOH I did not get other bids."

"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."

"It went really well! Gino Henn, the general contractor, is a man of his word! He sincerely wants the job done as if it was his own home. The men he has working on each part of the project show up consistently, they prepare the house to keep it as tidy as possible through the process, they are nice and respectful to work with and so good at what they do! I was very impressed with Gino‘s ability to connect with someone to do a specific job and be here as soon as I had a need. We had to move some air conditioning ducting in addition to the remodel. The patching and painting was so good that you can’t tell it happened! I love my new kitchen and bathroom, thanks to Gino and his amazing crew!"

"The Pinnacle Team was great to work with. They did our ADU and came in on time and on budget - the 2 most important things. The team is well staffed, knowledgeable, and easy to work with. I know how to do electrical work, and they let me do this, which more contractors would never let you do some of your own work. I certainly would recommend them."

FAQs for addition to existing structure building service projects in La Canada Flintridge, 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.
