"It went okay, except for three problems. One window had been measured incorrectly and had to be completed at a later time. Another window was not measured or replaced, despite reminding them that it still needed to be done. Finally, they broke a sliding glass door insert and didn't completely clean it up. I had to call them back to do it properly, and when they came, they had a bad attitude about it."

Customers say: Terrific value

"I had two leaded glass built-in cabinet doors that needed repair. The doors are close to the ground and kids had broken different panes over the years. Jim was very easy to work with. I was able to drop off and pickup the doors after hours. The quality of the repairs was excellent. I highly recommend contacting them for leaded or stained glass repair work."

"The installation team arrived promptly at 9am to begin work.  The installation team had the old window out and surface prepared within a the first half hour.  When the second truck arrived with the glass block panels the group installed the window.  There was a bit of a challenge with the vertical angle of the wall and one of the panels fell out on to soft dirt while being shimmed into place.  These guys are excellent bricklayers, and not only can you not tell where the vertical joints are between the panels, you cannot tell where they had to reset the rows as well.  Long story short, they did a terrific job, the window looks like one unit and the side of the garage looks great.  The total time for the job, arrival to departure was 2 hours.  The installation crew was professional and cleaned up the area leaving nothing behind.  The Ice pattern allows for the security and privacy we wanted AND allows a significant amount of daylight into the garage.  I will use Global Glass Block on my next glass block project.

"The service was second to none. Peyton and his team are professional, punctual, and masters of their craft. I cannot rate them highly enough, five stars does not do them justice. If you donâ t use this company for your glass needs you are missing out on the best!!!"

"AWESOME! Dan sent me a price (well below competitors) same day I contacted him on a comparable window. On installation day, his team showed up and got right to work. Before starting, they put tarps over my stuff and vacuumed when they were done! The window, superb quality of the installation and overall level of professionalism way exceeded my expectations! Love my new window, will be calling again when I'm ready to replace my doors."

Glass Block FAQs, answered by experts

Glass block mortar is the best choice for glass block window units. It is specifically formulated for glass block window installation. Glass block mortar is usually a mixture of Portland cement, sand, and special chemicals. It is a white mortar that is applicable inside and outside your home. Do not use regular tile mortar because it may not have the binding strength and flexibility required for glass block windows.

Their thickness depends on application, but most glass walls are typically 3/8 to 3/4 of an inch thick. Although it’s not as common, single panes of glass can also be 1 inch thick.

New glass costs anywhere from $3 to $100 per square foot. More specifically, tempered and insulated glass—a common option for sliding glass doors—costs between $10 and $14 per square foot.

Heavy glass tends to be more expensive than thin glass because it is stronger and more durable. In most cases, ¼-inch-thick glass is ideal for mirrors, and ⅛-inch-thick glass is ideal for residential windows. Heavier glass isn’t always necessary, and can be more challenging to hang or install. Work with a local window installation pro for replacement or new construction windows.

Options include tempered, laminated, and tinted glass for various needs.
