Use DEFENDER GLASS BLOCK, you will not be disappointed in any way! SPECIFIC FACTORS WHY: 1. Answers and returns calls/text right away. 2. Owners Zach – dark haired and Luke – wearing hat (pictures attached) extremely professional, great personalities and honest business practices. 3. Very reasonably priced. 4. Measure and installation within days. 5. No extra work, unless discussed with customer prior. 6. Leave work area clean and installation took about an hour for two windows. When I called Zach (pictures included) answered on the second ring. Was out the same day to measure, and by Saturday, Zach and Luke had two glass block basement windows installed. We will use DEFENDER GLASS BLOCK for all our glass block needs. Highly Recommended!

Zach and Luke did a fantastic job! I've got a 100 year old house so no 2 windows were the same size but they handled the challenge! They were courteous, cleaned the job site up and did a fantastic job. I extremely pleased with the work.

Very personable and extremely knowledgeable. Zach took time to go the extra mile and cares about what he puts into his work. Definitely would recommend this company to everyone! My windows (installed glass blocks) in my basement look absolutely wonderful! I am etremely happy with how the entire process worked out. Zach is such a nice person, and I am so happy to give hard working individuals that take pride in their work, my business! Pricing was very fair and very reasonable. Thank you so much!

Zac was wonderful to work with. He listened to my concerns and put them them to rest. He was meticulous in his work and clean up. I myself am a perfectionist and expect that in the work I have had done on my home. Zac took that as a challenge and meet and exceeded my expectations. I would highly recommend Defender Glass Block to anyone interested in this type of installation. You will not be disappointed. Zac takes pride in his work and company. He installs and treats your home as if it were his own.

Consistently 5-star reviewed for a reason! Zach was very easy to communicate with and did a wonderful job for a fair price. Our 92 year old house had 3 leaking, rotting, wood-framed basement windows. In a half-day's work Zach replaced them with beautiful glass block that looks a gazillion times better! Our only regret was not having this done sooner. Thanks for a job well done!
