A friend recommended Holler Glass Block because Kevin Holler did such a nice job on her windows. The windows are very secure. One of the competitors lied about the use of silicone. I checked, and using silicone is fine. It is so good that it is used for jet windows and all sorts of stuff.

Great work done by a nice guy!

Kevin's basement windows are nicely made. I had my old, junky mortar windows replaced with ones that have silicone holding the blocks together. The windows with the silicone are so much nicer - they let in more light and have a cleaner look. The silicone must be very strong - it is used on jet planes! I highly recommend Holler Glass Block.

Kevin's prices are the best. He built a beautiful shower in 2 days! We love him!

Kevin does great work. Prices are reasonable. He is nice to work with.
