Excellent! They even had to cut out a section of the exterior block wall to accommodate the additional width of the new French door. Our is an older home, thus the old French door was thinner. Their attention to detail went above my expectations, and my home never felt like a work site!

Glass block window services FAQs

If you have a problem with your window, such as broken glass, minor leaks, or a problem with your window being stuck, repairing the broken part might be a cheaper option than replacing the entire window. However, if you have a deteriorating window frame or major leaks, buying a new window will be the better long-term solution.

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.

Pros

Maintains privacy while letting light into the bathroom
Energy efficient
Sealed to prevent drafts
Aesthetically pleasing
Strong and secure

Cons

Costly to install
Challenging installation
Challenging repair

Window replacement costs between $180 and $410 per window, or an average of $280 per window. However, your specific replacement job could cost as little as $100 or as much as $750. Factors such as frame material, the number of windows you need, and the type of glass you order all impact the overall cost. For example, simple double-glazed windows will cost $3 to $6 per square foot, but the stronger tempered glass ranges from $12 to $14 per square foot.

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
