"We had cracks in the dyed mortar of the bricks above our garage. Grady took the time to match the color, even with the color having aged 10 years, and you would not even be able to tell that there was new mortar. If your project is anything like ours, you will not be disappointed."

Glass Block Windows FAQs, answered by experts

Luckily, glass block windows need minimal maintenance. Other than regular cleaning, the only maintenance involved in having a glass block window is inspecting for cracks every year and applying sealer to the mortar joints if the blocks are set in masonry mortar. Glass block windows hold up well against wind and moisture better than traditional windows and are not prone to rot.

DIY is possible for small projects, but professional installation ensures proper sealing, structural integrity, and a precise finish.

Heavy glass tends to be more expensive than thin glass because it is stronger and more durable. In most cases, ¼-inch-thick glass is ideal for mirrors, and ⅛-inch-thick glass is ideal for residential windows. Heavier glass isn’t always necessary, and can be more challenging to hang or install. Work with a local window installation pro for replacement or new construction windows.

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

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