"Desmond installed glass block in the basement window well to replace a leaking casement window. He quickly returned my call for an estimate and gave me a quote upon inspection. He installed the glass block perfectly along with waterproofing and even did an extra coating of mortar on the outside sill so that water would slope away from the window. The work was done expertly. I would highly recommend Desmond - he is very nice person, knowledgeable and performs stellar work."

"Fabiano was a pleasure to work with. He was punctual when showing up to provide an estimate and to the project itself. He gave me accurate time lines and updates in real time when fixing my deck. After comparing 4 other contractors to replace my deck, Fabiano gave the best quote with no surprises and the estimate was spot on! I would absolutely recommend Fabiano for your next project"

Glass Block 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.

Glass block windows come in various patterns and styles that offer privacy and unique aesthetics. Frosted or textured glass diffuses light and enhances privacy. Wave-pattern glass blocks imitate ocean waves with flowing lines. Ice-glass blocks resemble cracked ice. Fluted glass blocks feature parallel vertical grooves, adding texture and depth. Clear glass blocks, similar to glass Coke bottles, offer transparency with some distortion and may have smooth surfaces or subtle textures, adding visual interest.

Glass block windows aren’t fire hazards; fire-rated glass block windows can increase your home’s fire safety. Modern glass blocks are made with materials that can resist high temperatures and prevent fire spread. Most offer a 45-minute fire rating, while some increase it to two hours. Compared to the typical 20 to 90 minute rating for a double-pane window, glass block can increase your home’s safety in the event of a fire.

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. 

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.
