Glass Block Windows questions, answered by experts

Costs depend on wall size, labor, block type, and customizations like frosted or colored glass.

Glass block windows last about 15 to 30 years, which is the same amount of time, if not slightly less, than standard windows. Standard windows last 20 to 50 years. You can extend the life of your glass block windows by resealing them every few years. Hiring a pro for installation is also key to windows that will function properly for years to come.

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 blocks provide privacy, natural light diffusion, insulation, and a decorative aesthetic.
