• I needed glass block windows in my residence, contacted numerous companies, i choose Diamond Glass Block as the pricing was in my budget and i felt very comfortable with the knowledge, honesty, and professionalism of David. I was so impressed with the job, i had my wife call to get all the remaining windows done. Great job David and crew, i am so pleased. If you are in need of glass block do give them a call, you will not be disappointed.

  • We had 4 basement windows replaced and they did an amazing job. I had quotes from other companies but this place beat their prices. They left the areas clean and took away all of the debris. Top quality and good service. The owner, Dave, has a humble demeanor and quickly responds to your emails. You can’t go wrong with this company. Highly recommend!
