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.

Although glass block windows are made of multiple layers of thick glass, they’re still susceptible to breaking. If your glass block window shatters, contact a window repair professional to remove and replace the glass block. Don’t attempt to handle it yourself because the broken glass can be dangerously sharp. A window repair pro will have the tools and expertise to replace the broken glass block quickly. Before hiring, be sure to confirm the repair pro has experience with repairing or replacing that specific type of window.

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.
