"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."

"Working with Nathan & KN Remodeling was the best decision we made when undertaking our garage conversion job. Nathan understood exactly what we wanted, knew our budget parameters and provided us with a range of options that helped us stay within what we were seeking to spend. We wanted it to be NICE, but didn't need to over-do any of the finishes and spend needlessly on areas that were going to be used in-frequently. The end result was fantastic. The workmanship was of the highest order, the job was executed efficiently and with constant communication and oversight. The whole job was stress free and delivered on time. I can't recommend KN Remodeling highly enough!"

"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."

The finished addition seamlessly integrates with our existing home, and the craftsmanship is top-notch.

"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."

"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 Westchester, 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.
