Fantastic Support

“The staff at Castle Glass were fantastic in supporting us with our partition project! Not only were they quick to respond, but they worked around our schedule, including making adjustments to the final product. They worked off of someone else's drawing, and matched the price of a company that went under.

We have received so many wonderful comments from staff and guests about the partition they installed. We would definitely recommend Castle Glass for all of your glass installation needs!”
