"We had Dave and Brandon install 7 basement windows. What a transformation of my 102 year old house. I’m sure they were original. They were both very professional and thorough. Cleaned up after themselves. It did take several months to get the install date but they came on that date and on time! Price was very fair. I highly recommend Glass Block HQ."

"They were very easy to work with and worked around my schedule. There were no high pressure sales tactics. Dave did a fantastic job installing the windows....and he left my basement cleaner than when he arrived. I would use them again."

"I had 8 new glassblock windows installed in my basement. James from Glass Block Headquarters came in and did an outstanding job! I would recommend them to everyone, these are good people that do quality work at a fair price! Thank you GBH!"

"Decided to give them a call for an estimate on basement windows which are 50+ years old. They came out within a couple days and provided the estimate. The guy was very nice and kind and did not try and over-sell me like other companies I have dealt with! I put the deposit down and scheduled the installation for the next week. The installer came out and knew exactly what he was doing. He removed my old windows, installed the new ones, and cleaned up any mess that he made. The windows look gorgeous! The mortar is done very professionally and this is a great investment to my house. I will definitely recommend Glass Block Headquarters to anyone!!"

"Had 7 new glass block windows installed in our basement and we are so happy with the finished product. Dave was fantastic, nice, and did excellent work installing. Highly recommend! Oh, and their office cat is adorable too."
