Best Construction Company in Phoenix AZ

After reading reviews and speaking with several window replacement companies we purchased Infinity windows (11 windows and 2 sliders) from Capstone and had them do the isntallation. The results are amazing! Greg (one of the owners) came to our house and answered our questions about the product and installation process. He's a very good communicator and knows what he's talking about. The window replacement crew (Chris, Ed and Kyle) were fantastic in many ways. They were on time, covered our floors and furniture, worked hard and well together, cleaned up everyday and all had terrific attitudes/personalities. Hector did a great job repairing the drywall, covered our floors and furniture, cleaned up when finished and was also very nice. We're very happy with our new windows and highly recommend Capstone Windows and Doors.

Shattered a bedroom window and these guys came out and had it replaced same day! I plan on calling them to replace all my single pane windows with low e glass in the future. 5 stars!

Best decision I made going with Phoenix. Will for sure go back and do more business with them in the future. Ask for Alex!

SO UNPROFESSIONAL AND CANT GET IT TOGETHER!!! I have repeatedly asked to be removed from their calling list from several employees the last 2 months. I have received over 25+ calls and each time politely asked to be removed from the call list and I've heard I will have a manager remove you we just got a new system, our computers are getting updated BUT I still keep getting calls. Your Company is one I would NEVER USE OR RECOMMEND after the headache of being hassled for Windows relentlessly. Figure your new system out and when someone asked to be removed from your call list… Take them off. Simple!
