Glass Block FAQs, answered by experts

Yes, professionals can install decorative or colored glass block patterns for a unique look.

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. 

Most installations take 1-3 days, depending on the number of blocks and customization requirements.

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.

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.
