Glass Block Windows FAQs, answered by experts

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

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

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.

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.
