"Diego is a perfectionist & uses only superior quality glass and modern hardware. He installed a sliding glass shower door within a week of measuring and took only a few hours as he has a number of helpers. I’m so pleased with the result and it really makes the renovated bathroom a showstopper!"

"This was a very involved plaster repair and remediation job, in a very old house. Grady is the only person (or company) who was willing to take on the job and drive all the way from Pennsylvania to our home in Northern Virginia. There are very few people who do this kind of work anymore (we really searched) and he is an expert in his field. We needed to work around his schedule, because he is in demand in the tri-state area, so it took awhile to schedule the work to begin... but it was worth it."

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.

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.

Yes, many professionals provide custom-cut glass replacements for enclosures that require precise sizing.

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.

Although glass block windows are made of multiple layers of thick glass, they can still break. If an individual block shatters, it can be removed and replaced, but this is a job for a window repair professional. The project is often complex and may require breaking the block further for removal. Do not attempt to handle it yourself, as the broken glass can be dangerously sharp. A professional will have the necessary tools and expertise to replace the broken glass block quickly and safely. Before hiring, confirm that the repair pro has experience with this specific type of window.
