"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."

"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.

"Nathan impressed from the time I first met him. He was far more professional than other contractors in terms of describing how his company works and what I should expect if I worked with him. He also has a nice showroom where you can look a variety of cabinets in different styles and colors as well as countertops. We ended up getting a countertop that he suggested. We would never had picked it on our own but it ended up looking amazing in our kitchen. We had him do a complete remodel of our kitchen and one of our bathrooms. The guys on his crew were always prompt and showed up as scheduled. His foreman was both a good communicator and listener. Whenever we ran into an unexpected issue, they communicated clearly what additional costs would be involved (if any) and how much additional time it might take. The cabinets he installed were custom made but did not cost more than the pre-fab ones you can buy at the large home improvement stores. They are of high quality and well constructed. I actually saw his cabinet guy using a small caliper to make sure the door distances from the cabinets were all even! Lastly...here's something you'll never hear about a contractor...he finished AHEAD of time! Nathan's company are straight shooters and very skilled craftsmen. I would work with them again."

"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!"

"R Design was great. Ramy was able to match my existing plaster pattern and paint design. His crew was professional and they provided excellent service. Most importantly, they were willing to come back and make things right after I pointed out a few inconsistencies. We hired them to do additional work while they were here, which helped out tremendously. I would definitely hire R Design again."

"I hired Golan and his team from INA Kitchens to do a complete renovation of my 1980s old house from the installation of all the new drywall throughout the house, brand new engineered wood floor, enlarged and complete kitchen, and all the bathrooms including the master bathroom, new roof... You name it we included it. The final results of this entire renovation were absolutely beyond stunning. Golan and his professional team were an absolute pleasure people to work with and to see on a daily basis. His professionalism, honesty, and kindness were the main things that made our remodeling stress-free. We have already told him that we are going to be great friends."

"My husband and I just finished a remodel of our guest house in Sherwood Forest. We used a company called Universal Home Design Inc. The contractor and owner of the company Ouriel Lousky was most professional in every aspect of the job. His crews were timely and most efficient in every way. He had his subcontractors lined up so the job was never lagging behind. I would recommend him to anyone who is planning on a remodel or a renovation. Mary V."

"If you are looking for an honest contractor that does great work, look no further than ING Construction. We hired them to build a recreation room onto our detached garage, which came out amazing. 4 years later, we had them come back and turn that rec room and part of the garage into a legal ADU (Accessory Dwelling Unit). 3 of our neighbors have now used ING Construction for their projects. I do not think that you can find a better recommendation than that."

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