Glass Block Headquarters has been the best people I have ever had the pleasure to have work done to my house. From the estimate to clean up they get 5 stars. Had 4 glass block basement windows installed. Ron and his partner showed up on time, professionally installed my new windows, cleaned up to where you wouldn't know any work was done.(Actually left my place cleaner than when they started). Ron went over with me all the work that was done, answered all questions, and went over the life time transferable guarantee. Glass Block Headquarters does quality installation, uses materials with a life time guarantee, and all this at an affordable price. I will use Glass Block Headquarters again for any work they do. Give them a call, you won't be disappointed. P.S. Ask for Ron Sullivan.
People are Great to talk to, and the price for what I needed was excellent. The biggest thing that I luved about everything was that the company uses Wells Fargo for financing. This is such a big help with the way the economy is moving we all need as much help as we can. The Guy Dave who did the work was very professional and was knowledgeable about the work, he said he had been doing this kind of work for more than 17 yrs. I'm glad you had hem working on my home. Thanks Glass Block
What an amazing experience! I received an initial quote quickly. Within less than a month, I had 10 basement windows replaced, and a crew of just 1 came out and installed them in 6 hours. He was quick, efficient and professional. I would highly recommend this company. The quality of work was amazing!
"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."
The Project dictated we had go a different route However this Company has proven it's integrity in more ways than one! Honest and helpful sales representative that go above and beyond to help you with difficult decisions I would say Trust this Company hands down! Ms Martha Ka
"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."
Estimate done right away, office provided a date of installation and crew arrived exactly on time. Removed old 105 year-old basement windows and replaced with new glass block cemented in. They did a great job in filing in with cement the uneven bottom sills. The crew knew what they were doing and cleaned up when done. Great job and I only wish I would have done this years ago. The new block windows provide twice the light in the basement as did the old single pane windows from a century ago.
