​"Don demonstrated exceptional customer service.  He has great attention to detail and even made recommendations on options we hadn't even considered.  We are very happy with the products and service we received. We are also utilizing Phase Four Supply for a couple windows we will be replacing in our home very soon."   T.A., Rocklin, CA


"​Phase Four Supply is an amazing window and door company. We worked with them on several occasions on two homes that we are renovating. While working to replace windows at both houses, we never considered anyone else. Why would we? The  prices were excellent, his attention to detail was also excellent. I felt  relaxed and supported with any window related issue. We will absolutely work with them on the next job."  Mary Anne K.​


"These guys were amazing. Great prices, selection and service. I purchased windows for a total window replacement for my house. Don and his team did a great job communicating and handling everything I could not have asked for more. I would highly recommend Phase Four Supply for future work."  Stuart K. "Don has been phenomenal to work with. He has been attentive and has always followed through with his promises. In addition, Phase Four Supply has great prices…… You can’t ask for anything else…"  Keith M.
