Couldn't be happier with the three glass block basement windows installed by Keystone Glass Block. The entire project went smoothly and exactly on schedule. The installation team went above and beyond, completely clearing out the window wells. The windows themselves look great.

Keystone installed a glass block window for me. From Mike who answered the phone to Orest I'm not sure of the spelling of his name but he measured and installed they were wonderful. Very professional and easy to work with. I highly recommend this company. My window looks amazing

We are so pleased with our new windows. The customer service at Keystone Glass Block was wonderful. Every question was answered. Thank you so much.
