"I have held off on posting a review because I was hoping for a resolution. However, I've been waiting since May and it's now October. I hired this company twice. Each time they mismeasured the windows. The first batch of windows were installed incorrectly with the weep holes for water drainage blocked by the sill. Their own installer said they were a "tight fit." Custom windows should NEVER be a tight fit... they should fit just right. The second time they mismeasured the windows by nearly a foot, and they had to cut the framing of the living room open to accommodate. They left a mess of shards of glass in my lawn because they used hammers to remove the old glass. They were supposed to fix the weep holes. They have sent people out at least three times who all said that these were done incorrectly. They have not yet fixed any of the problems. I'm attaching photos to show how there's no way that water can drain from the window well which was pointed out to me when I had my windows washed professionally. They have been consistently late, the quality is lacking, and they aren't supporting their product or service. I have tried to be patient and supportive of a local small business. However, they have been paid in full but will not fully warrant their work from defects so far."

"Karl came out and looked at our windows and gave us a brief presentation about the windows he offers. He wrote down some good prices for us. After talking with my husband I called back and asked for a complete quote, including information on what things would be included, such as permits, licensing, which windows, etc, so we could agree to specifics. Among other things, he replied that he does not do permits with the city because he doesn't think they are necessary. When I pressed him for an actual contractual estimate listing what would be included (not just a hand-written estimate on the back of a paper), he said he did not think we would work well together and he did not need my business. He hoped I had a nice day. I was astounded. The lack of professionalism and the number of red flags really ruined my experience with this company. Is it a shady company? I don't know. But I am surprised that actually writing an official estimate would mean we are being difficult customers. It's too bad because he was personally very nice and as I said the initial prices were fantastic. Apparently, it was simply too good to be true."

Glass Block questions, answered by experts

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

Glass block windows aren’t fire hazards; fire-rated glass block windows can increase your home’s fire safety. Modern glass blocks are made with materials that can resist high temperatures and prevent fire spread. Most offer a 45-minute fire rating, while some increase it to two hours. Compared to the typical 20 to 90 minute rating for a double-pane window, glass block can increase your home’s safety in the event of a fire.

Installation costs range from $400 to $1,500, depending on wall size, design complexity, and labor.

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. 

If an individual block breaks, you can remove and replace it. This is a job for which you should contact a professional because the project is usually complex, involving you having to break the block further.
