"Don made the drive out to my home to measure my existing basement window openings. He then sat down with me and explained to me what my options were as far as glass blocks and different features available. He was fully prepared to show me how MGB produces the windows and the install process. I thought the pricing was very fair and they had the block windows finished in just a few days. Both Don and Scott in the office were extremely professional and answered every question I had. I would highly recommend Maryland Glass Block."

"I am very happy with the work performed by Advanced Glass. We solicited multiple bids, they were the lowest cost. Also, they were very helpful with design ideas (what works and does not). Install was on time (3 hours); very nice work. Cleanup and low noise. Excellent! Now we have a very fancy glass shower. Wife is very pleased and we saved several hundred dollars over other other bud prices."

"Our Honda CR-V had a large and expanding windshield crack. The
Derwood/Rockville office of Royal Glass seemed to offer the best value.
They did an outstanding job in replacing the windhshield, were easy and
professional to deal with. I'd certainly recommend them

"I was very disappointed. I spoke to William on the phone but unfortunately the person that came out to actually do the work was unreliable and performed messy work. Maybe I was unlucky to get another person. They were late arriving and then asked to take my window somewhere else to work on the glass. I said ok but was very clear I needed to leave several hours later to pick up my kids and was told no problem he would be back in plenty of time. The person did not return even an hour after what was promised. I tried calling and got no return call. I eventually had to leave my house with a missing window which did not seem safe to me. When he returned hours later there were muffled apologies. He seemed like a nice guy but no effort at customer service. Then he began working on other cracked glass at my house. After he left I looked closely at the work and the transom window glass replaced is very messy with glue or caulk messily left on edges. Very disappointed. It is hard to get someone to do this type of work done and Boston was recommend by several I know but maybe I just got unlucky that William didn't actually do the work at my house."

Glass Block Windows FAQs, 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.

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.

Yes, many professionals provide custom-cut glass replacements for enclosures that require precise sizing.

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.

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