"I was amazed. We had 10 new windows replaced, and after working a 10 hour day, I was dreading going home & cleaning for the next 10 hours. But when I walked inside my home you didn't even know they were there. everything was placed back to where it belonged, there was no mess to vacuum. There also was no mess outside, my garden was not even touched. The only thing I had to do was wash the windows and hang the curtains. They were very nice & polite, professional men who installed the windows. The windows themselves are 100% perfect. We could not be happier and could kick ourselves for not doing it sooner. They gave us a date in July for Installation. They arrived in May."

Glass Block FAQs, answered by experts

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. 

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.

New glass costs anywhere from $3 to $100 per square foot. More specifically, tempered and insulated glass—a common option for sliding glass doors—costs between $10 and $14 per square foot.

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

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.
