"Pristine Construction is a class act!! We gutted and completely renovated two bathrooms, and had wood floors installed throughout our home. As part owner and designer, Nathan comes to discuss your goals and holds your hand through the whole planning process if you want. Mike, also part owner of Pristine, is on the job everyday making sure everything looks perfect. Their crew is top notch skilled. Attention to detail is a hallmark of Pristine's crew as well as regarding Mike's and Nathan's expertise. Cooperation and responsiveness from our first meeting and initial plans, throughout construction, and when needing changes makes working with Pristine very easy. Pristine's positive approach in pleasing its customers and offering overall and detailed suggestions makes this company especially great. The crew was here promptly everyday, so unlike the horror stories one hears. Scheduling is well planned and efficient. In addition to Mike, Nathan and the crew, Pristine's friendly and professional office manager, Emma, provided almost daily communication regarding work scheduling and updates. I got their name from YELP and Angie's List and agree completely with all the positive comments. We highly recommend Pristine Construction for your next job with a professional, reliable and friendly residential construction company."

"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."

"Our initial meeting with Suj was great. Initially, we had in mind a much larger job. He had quoted us $3000 for the closet demolition / wall rebuild (non-load bearing), packaged with several other items. Together with the fee for drawings ($4000) and permits, this was a bit higher than we anticipated. However, we decided to go with Suj due to his responsiveness and professionalism. Out of our other quotes, Suj’s pricing was middle of the pack - not the cheapest or most expensive. When the drawings were complete and evaluated, he gave us an updated cost of $6000 over text message. The scope of work had changed, and this was no longer part of a bigger project - understandable. The issue was when he gave us the official estimate a week later and up’d the price once again to $9000. When asked what happened, his exact words were “well, I need to get paid too”. He had weeks to consider before quoting the $6000 and nothing had changed since then. The extra $3000 may be insignificant compared to most renovation costs, but for us in our first home, this was back breaking. We continued with Suj since we were already locked in and well past the 3 day cancellation period. Their work for the most part was exceptional. The new wall blended perfectly into our existing structure, and the ceiling patch was also well done. The problem here was the floor. They had dug up a 1” deep pit in the floor, likely to remove the wall studs. However, they did not patch the floor or even let us know this was going to be an issue. We were never told about the pit until I decided to check in on their progress one day towards the end of the wall build. This required us to pay a handyman to come in next day on a weekend to patch the concrete since we had cabinets being installed the following Tuesday. Suj was aware of this and did not believe it pertinent information. Overall, Suj and SoCal Builders do quality work, but the issues in pricing consistency lost us before the work even started. Not even telling us that we’d be left with a 1” deep pit in our floor after was another huge issue which should’ve been brought up much earlier. This was our first experience with a contractor and I’m not sure if this is typical or not. However, it’s enough to make me doubt I’d contact them for any future work."
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 decided to convert my garage into a ADU building, to get extra space. I worked with Kris and his Architect from Creative Home Remodeling on the design and plans. After we got the plans approved back from the city Kris started to build my new space based on his design. We added a small kitchen with a living space and nice bathroom. It has become a very nice place and I love it. Thank you Kris and Creative Home Remodeling."

"I'm grateful for the remarkable transformation of my previously awkward 2 bed/1 bath into a fully functional 2 bed/2 bath plus office. After interviewing several companies, I chose HIC Construction because Idan was open-minded, thoughtful, and had good ideas for my first renovation project. Choosing a contractor is like a marriage, and Avi delivered on what was promised, mostly within the expected timeframe. We rearranged plumbing, added a subpanel for a larger kitchen, replaced ducts, added a new furnace, and created two new bathrooms. I appreciate project manager Avi for navigating project issues and assisting in design and investment decisions. I look forward to witnessing your company's continued success."

"We hired Trig Builders to tear out our bathtub, shower and shower walls and to build a tub deck with a drop in tub; install marble tiles on the shower floor & walls and vanity backsplash, remove and relocate the old recessed lights and vent fan and install the shower/bath all plumbing fixtures. Like most other people, we also had many other bids before deciding who to hire for that work and at the end of this hard process, we decided to go ahead with Trig Builders. Our decision to hire and work with them was based on their positive online opinions from other clients and the excellent reputation that they have. At first, we worked only with Michelle about the design and the selection of materials of the project. It was a pretty easy and not complicated to work with her. At the end of that process, we were extremely happy with the overall design and the flow of the space. After that stage, Yossi was assigned to our project and he took over with the designs and flow. During the work, we had close to 6 workers that worked daily on the entire project starting with demolition, framing, and construction, paint and finishes installation. By having all this people working at the same time, we felt and noticed that the work is running super-fast and we loved it! Yossi made sure that each stage will be approved by him and this was the main reason why he visited our house on a daily basis (sometimes even more than once a day). The work was completed after 3 weeks from the day that Michelle met with us and we approved the design and the flow. At the end of the work, Yossi and Michelle came over to the final meeting where we inspected all the work and the final project. During that meeting, we informed them about few issues and Yossi was able to take care of them the following day making sure that they all will be resolved and approved by us. This is the greatest service we could think of. Trig Builders did a great work and we do recommend them for any construction work."

"I did not fully know this about me, but I am the client from H***. However, Mr Gino and everyone at imperial remodeling went above and beyond any expectations I could have had. And I am a perfectionist; which does not exist, but no one could have gotten closer than these guys. We did a complete remodel of three bathrooms floors, walls paint etc. I’ve had custom glass installed. And they built out a whole new bathroom for me without destroying the design and functionality of my beautiful mid-century modern home. I am definitely going to work with them again. I hope they work with me( Please read first sentence again). You will not find better quality and affordability in the same place as I did. Thank you imperial remodeling for treating my home as it was your own and for caring about us and exceeding all our expectations. You are the best at home remodel and I am glad we met!"

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