Installing glass block windows has benefits and disadvantages, as with most materials. The pros and cons can vary depending on the type of glass block and the window location.

Cons
Costly to install
Challenging installation
Challenging repair
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.
The average cost to install glass block windows is about $710, ranging from $460 to $1,000, depending on the size and design of the window, installation type, and location. Different styles of glass blocks also impact the cost:
Clear glass blocks: $10–$30 per block
Colored glass blocks: $25–$40 per block
Acrylic glass blocks: $15–$25 per block
Wavy glass blocks: $10–$30 per block
Alpha glass blocks: $15–$25 per block
Ice glass blocks: $20–$35 per block
Diamond glass blocks: $20–$75 per block
Frosted glass blocks: $30–$35 per block
Typically, glass block windows last about 15 to 30 years, slightly less than regular windows, which last 20 to 50 years. Resealing glass blocks can help extend the lifespan of this bathroom feature. The key to ensuring that glass block windows last as long as possible is to have a professional glass block installer place them. Glass block pros will have the skills, tools, and knowledge required to install these special features into any space, noting obstacles like damaged windows or too-cramped areas during the consultation.
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.
