"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."

Chicagoland Window Wizards is a family owned and operated business where we treat your family like ours. We will beat any comparable offer by 5%!

"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

Glass walls are more expensive overall than their brick or drywall counterparts. However, if you need walls for a building with more than two or three stories, glass walls are the more budget-friendly option.

Their thickness depends on application, but most glass walls are typically 3/8 to 3/4 of an inch thick. Although it’s not as common, single panes of glass can also be 1 inch thick.

Glass blocks provide privacy, natural light diffusion, insulation, and a decorative aesthetic.

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.

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
