"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 called and he was able to come right away and pick up the table.  Promised to have it ready in one week, and true to his word, had it back the following Saturday.  Delivered the table, and reinstalled the medicine cabinet mirror.  I am very pleased with the service and the job.  Would recommend him and would use him again.

"I phoned POL GLASS to request an estimate to replace the broken glass in my egress window which was causing condensation. Mr. Brych was professional, knowledgable and very responsive. He came right out to my home to assess the damage, provided me with a reasonable estimate, promptly ordered the part, phoned once it arrived, and performed the installation, all within a 3 day turnaround!! My Brych's expertise and experience resulted in a top notch work product of superb quality. I would highly recommend POL GLASS for all your glass needs; satisfaction guaranteed!!!"

"Sergio installed a new tile countertops and stone backsplash in my kitchen. His work was perfect! He was easy to contact (Thank you, Monique), prompt, courteous, started the job right on time, stayed with it until it was finished, also right on time, and his price was very reasonable. I had one tiny thing I wanted changed and he took care of it right away and without complaint. I recently needed his help to finish a job started by someone else and he was there within 48 hours! My house is 97 years old, and over the past 20 years, I've worked with many contractors , but Sergio was by far the best. I would recommend him without reservation."

Glass Block questions, answered by experts

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

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.

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

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.

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.
