Our Happy
Customers

claudia valdez ★★★★★ When planning my home addition project, I needed a reliable contractor and discovered Prime Design & Build. After researching various companies in the area, they stood out as the ideal choice for my project. From the beginning, Noah was incredibly cooperative, providing detailed insights on home additions and working with me to create a budget-friendly plan. The team was thoughtful and flexible, which was especially beneficial for me as a first-time project manager with numerous questions. I truly appreciate their dedication and hard work. Thank you!RHUSTI CALIPAYAN ★★★★★ The team at Prime Design & Build demonstrated outstanding dedication, resulting in a fantastic room addition project! We couldn't be more pleased with the final outcome. Prime Design & Build skillfully expanded our living space, showing unwavering commitment and remarkable attention to detail. They not only met the project deadline but exceeded our expectations by completing it ahead of schedule. The quick turnaround and exceptional craftsmanship in creating our new room have left us absolutely delighted. We recommend them—grade A+ work!Glenn Douglas ★★★★★ My wife and I have lived in our Palo Alto home for thirty years. Just recently we needed help with roofing, new windows, and other household upgrades. We were fortunate to have Daniel Zinger of Prime Design & Build as project manager. Daniel is the best project manager we have ever encountered. Ever! Daniel gave us helpful options at every stage. He never pressured us. He was always available, and delivered on every promise he made. He was astonishing. We give our highest recommendation to Daniel Zinger and Prime Design & Build.Cameron Duffey ★★★★★ They did a fantastic job staying organized. Even with the complexities of our home addition, they kept things on track and finished on time. A key team member ensured everything was exactly as we wanted. Their dedication and attention to detail made the process smooth and enjoyable. We greatly appreciate their excellent service!Melisa Soliman ★★★★★ Highly recommended! Daniel at Prime Design & Build was a pleasure to work with. He is very good with the clients, management of the various teams and creating a great work environment. He's super competent and full of good ideas and help.I was very skeptical of contractors, and really just felt misled by them in the past. Daniel single-handedly turned my opinion around by being honest, trustworthy, extremely competent, pleasant and helpful. We had a fantastic experience with Daniel as the lead. The company owners also had some good suggestions and I thought that was nice of them since it was extra consideration on their behalf.We had everything done, inside and out to prepare our house for sale, including painting, flooring, refinishing cabinets and floors, new laminate, roof fix, LED cans put in, new fans, etc. The house looks beautiful and very professionally done and I'm quite picky.I highly recommend Prime Design & Build, and highly recommend having Daniel as your project lead. I will certainly contact him in the future for all of my remodel/renovation needs.Tracy A Todd ★★★★★ Joseph was a consummate professional which gave us confidence that PD&B was the best company for our new roof project. He and the team did not disappoint! They did an excellent job and we would recommend them without reservation!js_loader
