How great to have a contractor show up when they say they will. These guys did an awesome job. Very professional taking a lot of pride in their work making sure everything was cleaned up from the installation. The windows are really high quality and cant imagine there being a better window on the market. I would highly recommend them to anyone.

Had three basement windows replaced. Vanguard was at my house within the week and the windows were replaced in a few hours. It was quick, reasonably priced, and they look great. Thank you!

I had my basement windows, windows on my main floor and sliding door replaced and installed by John and Todd. I couldn’t be happier with the job. John was very responsive and prompt on installing the basement windows. I mentioned some bad luck I had with a previous contractor for the windows and door and John worked with me through the whole process and I am very happy with how it all turned out. Highly recommend!!

John, the owner, was very easy to work with in communicating pricing and availability. He did a great job on the window in our bathroom it looks great. Would highly recommend!

I had a great experience! Called on Thursday and the job was started on Friday as promised!! The block glass windows brightened the basement really well!! I wish that I could post pictures of before and after!!!

John from Vanguard Glass Block Windows is very professional with a personable touch. All work is done in a very timely fashion. Its been a pleasure working with him & Vanguard over all. Great company. Highly recommended!

Quality work, arrived on time, friendly, job completed as scheduled. Would recommend or use again in the future. Thank you.

John is seriously one of the nicest contractors I have ever hired. As a woman, sometimes its uncomfortable just having a random man working in your house, but with John I dont feel this way AT ALL. He was so incredibly helpful in helping to keep the pests etc. out of my basement by installing my new windows! You can tell he genuinely cares about making his customers happy. Im so thankful my neighbor referred me to him!

John is awesome. He was professional and personable. He completed the job very quickly and it looks great. I highly recommend his work.

John was prompt, professional, tidy and very knowledgeable. Fair prices and excellent work quality makes him my go to guy for glass block in the future. Highly recommend!

John with Vanguard glass block did a amazing job and and going to reccomend him to family and friends as much as a can...

John the owner was amazing . My windows were so damaged and hard to remove he took care of it all and cleaned up the mess . Left a polished clean window . I’m so happy and no matter how much rain is super dry . I highly recommend him . Super fast, affordable and effective .
