Customer Reviews

  • "I hired Window World for an install of three extremely large slider windows. These are windows other companies said could not be done. The windows were installed over the course of a day and a half, and the installers exceeded my expectations in every way, as did the quality of the windows! I highly recommend them to anyone!"

  • "I had two windows that I haven't used for over 30 years. One of the window panes actually blew out during a wind storm. I called Window World and Wayne was great! They were very professional, friendly, cleaned up all the mess and did a GREAT job! Thank you Window World, we will definitely go back to you when we need new replacements!"
