I would never go anywhere else for interior window treatments! Great service. I worked with Leslie, and everyone in the store is friendly and helpful as I explored my options. I took several samples home to see how they worked in my windows. The tiny samples are not the greatest for gauging...

These guys were AWESOME! I can't say enough about how impressed I am with the job they did on my old aluminum storm windows. They were filthy from years of neglect and I'm happy to report they are now sparkling clean. These old aluminum storm windows are a real "pane in the glass", but the...

Jim has done windows for me for over five years at two different houses. Simply put, he does an outstanding job and undercharges for his work. I first found Jim at a home show, and between that and word of mouth Jim doesn't advertise any. At my present house, which has 35+ panes on two...

The job was done well. He responded to my calls and kept me informed as to the progress of the windows coming in and when he could be there to put them in . I felt his prices were fair and done in a professional manner. I would recommend Carnation Glass to others.

I contacted All Service Glass for an estimate on replacing two cracked windows and replacing five window screens. The estimator came out and was friendly and punctual. He listened to our concerns and even gave us a bid on another window project which we were considering for the future. He...
FAQs for glass block window service projects in Sultan, WA
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.

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
