"...The owner Dave Mancuso and his crew have replaced all of the windows and sliding doors in our San Ramon home over the last decade. Dave's workmanship and professionalism has always been rock solid. My wife and I also really appreciate that Dave's team is super clean and leave the job site without a trace of debris or dust."

"Great job by Premier Windows and Doors. We had all the windows in our home replaced and Dave and his crew did a fantastic job. We had shopped around and found their prices very competitive. They were very professional, clean, and paid attention to detail. I will have them back for some interior doors soon."
