"We ordered a window from them the end of April. The beginning of June they came to put the window in. They had ordered the wrong size. The said that they would rush order it and we would have it in a month. After waiting a month and not hearing from them, we called to find out when the window would be put in and they said that they would check and get back with us. After many more calls we were told that the window wouldn't be in until July 23rd. We requested a refund and after many more calls were told that they don't give refunds. The window was finally installed on August 2nd over a week after they received it. We will never do business with them again.!"

Glass Block Windows questions, 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.

You can still see vaguely into some types of glass block windows at night. Although there won’t be clear definitions, passersby may still see shapes, shadows, and movement through the glass. If you want complete privacy, consider installing diamond glass block windows rather than the typical clear or wavy glass blocks.

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.

Regular cleaning with non-abrasive cleaners helps prevent buildup and maintains clarity.

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