"Pristine Construction just completed a kitchen remodel for us this December. The project was finished on time even though additional projects were added along the way. Everybody from Pristine Construction did their job in the most professional and honest way possible. Through Angie’s List reviews, I came to know their reputation. And these reviews helped me to contact Pristine. The reviews were written in a way that I saw and experienced personally the good things about Pristine Construction. My wife and I were impressed from the start. Nathan and Mike listened to our needs and tried their very best to fulfill them. In my opinion, the crews and staff are the best in their field of expertise. Throughout the project, not only our 1950s-built house had kitchen upgrade, but also had other upgrades done. These other upgrades were done without sacrificing the timeline of the project. My family are all thrilled with the result of the project. I am proud and right in choosing Pristine Construction. I will choose them again on my next home improvement projects."

"I hired Golan and H&A My Design to build an ADU and they did excellent job and exceed my high expectations. The project went smooth, there were no issues and was finished ahead of schedule. It was a true pleasure to work with Golan and his team and final product is a top notch. Also this company have a one stop shop showroom for all finishes, 5000 square-foot. I highly recommend H&A My Design!"

"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."

"We've been in our Lakewood home over 27 years and finally made the decision to put our "60's kitchen out to pasture. We had three good contractors bid for this project. We were most impressed by Ben of Creative Home Remodeling Group. His enthusiasm, attention to detail and follow-thru remained constant from concept to completion. Ben overperformed and under promised. His crew of company contractor specialists have been with him for years, and their rapport and communication showed in the finished project. He was on site and/or in phone contact with them and us constantly. They finished ahead of time with Ben staying on task through each stage and to final inspection. No reflection on Ben or his company, but us being a first- time user of a contractor's services, we were a little green about the process, the quotation and what to expect. It is often said to add 20% to the bid for unexpected costs. There were two legitimate additions that couldn't be anticipated. They were fully explained and understood. It is important for anyone doing this, to make good notes and keep in mind what the bidder is contracting to provide and what your responsibilities will be. Ben made this clear from the start-nothing hidden. Many items required us to go to the vendor, choose, and to pay directly, outside the bid parameters. These items-specifically: the vinyl flooring, the quartz counter tops and backsplash, sink, faucet and disposal being the main ones. For the most part, only the highest expense (the cabinets) was factored into the quotation. My wife and I would use Ben and Creative Remodel again and recommend him and his Studio City company without reservation"

"HIC builders is a family owned company, and they did a terrific job at my house. We added an ADU above the garage, remodeled two bathrooms, and did other extensive work on the house. Abraham, the field manager, was responsive and available, flexible when plans needed to change to accommodate structural issues that we discover as the project progressed, and answered my endless questions. The workmen were always on time, courteous, and cleaned up the site every day before they left. Probably the easiest way to find out if HIC can provide what you want is to call Abraham Moryossef directly (818 850 5062) and chat. I know it will be a good investment of your time. They are terrific!"

"Construction Masters just finished building an additional room in my home as well as building a bathroom from scratch. I am completely blown away! I had very specific plans when it came to this room addition and new bathroom. They met and exceeded all of my expectations.

I'm really enjoying it!"

FAQs for addition to existing structure building service projects in North 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.
