"Made an appt. with Castle Rep, James, for 17 windows and vinyl siding. He spent 1 hour talking about how great his company and windows are before finally getting down to the issue. We were told that CASTLE makes and services their own window, with all the best technology and technicians available. The price per window for energy efficient came out to over $1,200 per double-hung window! And since they make their own products, we could not find a way to compare quality and price with other manufacturers. But his per-window price exceeds the average price of $500-700 by A LOT! When we balked, he made a call to his "manager" to see if we qualified for a "special promotional" discount. If we were to commit right there on the spot, we would get an additional 10% off! Still way to high. We said we would think about it (he got sad and snippy), and that we wanted to hear about the vinyl siding quote before we made any decisions. He told us he could not give us a siding quote until his company did an "eagle view" measurement, which would require another appointment! We had no intention of sitting through ANOTHER high-pressure appointment. High pressure, long-drawn out presentation and he would not leave us with anything in writing! No brochures, prices, nothing! He refused to put anything in writing and we could not have a break down of labor and costs. I even asked him if I could have a copyhh of the window warranty and he said "only if you purchase right now." And they did not come prepared with references or previous job locations! When we further researched the company, we found they did make very excellent products, but the #1 complaint was by far that they did not honor their lifetime warranty and that customer service was horrible. In the end, we chose not to do business.."

Glass Block questions, answered by experts

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.

You can still see vaguely into some types of glass block windows at night. Although there won’t be clear definitions, passersby may still see shapes, shadows, and movement through the glass. If you want complete privacy, consider installing diamond glass block windows rather than the typical clear or wavy glass blocks.

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. 

Glass block windows come in various patterns and styles that offer privacy and unique aesthetics. Frosted or textured glass diffuses light and enhances privacy. Wave-pattern glass blocks imitate ocean waves with flowing lines. Ice-glass blocks resemble cracked ice. Fluted glass blocks feature parallel vertical grooves, adding texture and depth. Clear glass blocks, similar to glass Coke bottles, offer transparency with some distortion and may have smooth surfaces or subtle textures, adding visual interest.

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.
