"A great team! One of those that you wish you had more than five stars for rating. We had a loosely defined project to repair/rebuild around the house perimeter. They did like five different things, including a large concrete deck, repair balcony, and a new door. We have only very positive things to say about them. They clearly care and do everything very professionally. They have all the proper equipment (like that CAT bot) and, most importantly, they know how to do anything, what tools to use, and, in our case, they purchased all materials. We certainly hope to keep working with this team in the future. We completely trust their judgment and expertise."

Glass Block FAQs, answered by experts

Yes, professionals can install decorative or colored glass block patterns for a unique look.

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.

Luckily, glass block windows need minimal maintenance. Other than regular cleaning, the only maintenance involved in having a glass block window is inspecting for cracks every year and applying sealer to the mortar joints if the blocks are set in masonry mortar. Glass block windows hold up well against wind and moisture better than traditional windows and are not prone to rot.

Glass block installation can be relatively expensive due to the range of material costs and the labor time to assemble this type of specialty window. The process proceeds slowly as the glass does not absorb moisture from mortar and silicone caulk takes longer to harden, leaving spacers to hold up the structure until the caulk or mortar begins to cure. Plus, if your current windows have structural issues or damage, you’ll need to repair them before beginning the project, increasing your bottom line. 

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.
