What Our Customers Say
Our clients are at the heart of everything we do at 9Builders, and their feedback reflects our dedication to quality and service. From beautiful remodels to innovative new builds, hear how we've transformed their spaces and exceeded their expectations.
Tommy, Yuna, and their entire team were amazing from start to finish. We hired them for a big project that included foundation work, a structural retrofit, replacing the PGE main service line, and installing a new 200-amp panel. It was a pretty major job, and honestly, we couldn't have asked for a better crew to handle it. Everyone was professional, polite, and knew exactly what they were doing. They showed up on time, cleaned up every day, and were super respectful of our space.
I hired 9Builders to work on my backyard and they did an amazing job. They built a nice structure that looks really great and added so much to my yard. The team was friendly and kept everything clean while they worked. The work was done quick and looked really good. Now they're working on the front of my house to add an extension, and I'm impressed how fast they worked. They finished the foundation in just two days...
9Builders transformed our kitchen into a beautiful, functional space. They listened to our ideas, offered great suggestions, and delivered high-quality work. The team was professional and respectful throughout.
