The professionals at AA Millennium Glass were quick to respond, followed through on their quote in a timely manner, and had the repairs complete within a very short timeline. The windows and mirrors look great! I'd definitely use their services again.

This was my second time hiring Handy Ma'am (the first was also great), so I had every confidence that she was going to solve the problem. But I had no idea that I was actually going to LIKE the result. Her idea was to use plexiglass and she used her contacts to get a perfectly cut fit for the...

They are nothing but frauds and crooks. If you are looking for a major stress and a lawsuit, this is the place to go. I took in a few wood windows with 100+ year old antique glasses with lovely ripples. The windows had small cracks at one corner. The idea is to save the glasses as much as...

These guys were great and paid close attention to detail! Our windows are crystal clear and we aim to use them every 3-6 months or so in the future for sure! ***updated*** A day after they left, I started to notice a few places they missed unfortunately. 1 screen in one room was completely...

Now I understand why they book several months in advance (good companies stay busy). They do the historic restoration work that very few people know how to do anymore. My home is from 1925 and Brian Saffel was able to make the wonky windows in our bedroom/bathroom work like new again. Highly...

FAQs for glass block window service projects in Glendora, CA
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
