"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."

"We had converted our half bath into a full bathroom. Bridgestone construction offered accurate timelines, competitive pricing and committed people to complete the work. They also handled all the paperwork and permitting and followed up with our local inspectors so that the work could be completed on time. They were extremely clear at all the milestones and payments were structured after the work was completed. Their people kept to covid protocols (taking temperatures everyday, masks all the time, daily record of everyone who was working), and worked with very high quality. Jeremiah was a pleasure to work with, He did a great job of minimizing disturbances to us. They were great at adapting to all the various issues that came up to ensure the job was completed on time with high quality."

"We absolutely love our new home. We had our kitchen remodeled, our hallway, which is now our beautiful laundry area, our two bathrooms, new flooring installed in those areas, recessed lighting, new central air and heat, the electrical upgraded, new plumbing in areas that needed it, the exterior and interior painted, and our structure retrofitted. Even though we didnâ t add square footage the inside of our home is unrecognizable. Everyone that comes to our home canâ t believe the changes, and how beautiful it came out. We love it! We met with at least four other contractors before deciding to go with H&A My Design. Ben, the Project Manager, immediately made us feel comfortable, and made a great impression with us. He was with us from the get go and through to completion. Meshi was added to our project shortly after we started. So there were now two Project Managers. Meshi was an excellent and pleasant addition. Meshi and Ben were on top of everything. Between her and Ben nothing went unanswered. Every good relationship does have some stumbles, how they are resolved determines everything. Whenever we had questions or concerns during the project we immediately received a text, a phone call, or Ben or Meshi would drop by. They were hands on, and never difficult to reach. They both immediately addressed any issues we had. When the project was complete Ben and Meshi even brought our fur babies fun gifts and tasty snacks, along with a gift for us. About three months later, we noticed some issues. We contacted Meshi and Ben via text and sent pictures. She immediately sent someone out and the job was complete within 24hrs. The project took about three months to complete. Overall, we had a great experience, and we are very happy with the outcome, the professionalism, and the time frame. We would use, and highly recommend, H&A My Design for future projects, and Ben and Meshi as our Project Managers. Thank you Ben and Meshi and H&A My Design! We couldnâ t be happier."

"AGB was the perfect choice for our duplex apartment in the UWS full total gut renovation, we did not leave anything old in the apartment from flooring to full electrical changing the location of the kitchen and removal of the walls and ceiling all the way to studs expanding my master bath and more.Every part of the apartment needed to be redone. We hired AGB to fully design and build our apartment and it was just amazing experience they handled everything for us from building approvals to filing with the DOB and creating a beautiful design for our new apartment and they have everything you need for the renovation, great design team and very professional crew members and project managers it was a real pleasure working with a firm like America Green Builders thank you Osher, Mike, Sean and rest of the AGB team."

"My husband and I really enjoyed working with Ben and his team at Creative Home Remodeling Group. Ben oversaw everything from making the plans, getting them approved by the city, scheduling the entire build and doing all final inspections. We really appreciate how communicative Ben was with what day and a time window we could expect the different work groups to come and what work would be done those days. If my husband or I ever had questions or problems with anything that was going on during our construction we were encouraged to call Ben and he helped create a solution that was workable for all of us. We liked that Ben and his team took care of everything from beginning to end and we did not have to hire any additional contractors along the way. We did have to purchase the specific fixtures and tiling we wanted.) We added apx 200 sq feet to our home, which included a bathroom, walk-in closet and room extension. The total process took exactly 1 year from signing our contract to us being able to use our added rooms. (That included making the plans, getting them approved by the city, the build, the installation and final walkthrough with the city inspector.) I would recommend using Ben and his team at Creative Home Remodeling Group to my family and friends. We look forward to working with Ben again in the future."

"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!"

"Axe Construction is the real deal. From start to finish, they handled everything—helping us find the right property, managing the full demo, collaborating on the design of a brand-new home, and executing the entire build. What’s impressive is that they delivered all of this within a 13-month timeframe, which is almost unheard of for a ground-up custom build. Communication was clear, decisions were practical, and the team stayed solution-oriented the entire time. No endless excuses, no finger-pointing—just progress. They understand design, construction, budgets, and timelines, and they know how to keep a project moving without sacrificing quality. The final result exceeded our expectations. The house is beautifully built, thoughtfully designed, and feels solid in every detail. If you’re looking for a contractor who can truly handle a project end-to-end—and actually deliver—Axe Construction is the team you want. Highly recommend."

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