"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.

"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 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.
The average cost to install glass block windows is about $710, ranging from $460 to $1,000, depending on the size and design of the window, installation type, and location. Different styles of glass blocks also impact the cost:
Clear glass blocks: $10–$30 per block
Colored glass blocks: $25–$40 per block
Acrylic glass blocks: $15–$25 per block
Wavy glass blocks: $10–$30 per block
Alpha glass blocks: $15–$25 per block
Ice glass blocks: $20–$35 per block
Diamond glass blocks: $20–$75 per block
Frosted glass blocks: $30–$35 per block
Typically, glass block windows last about 15 to 30 years, slightly less than regular windows, which last 20 to 50 years. Resealing glass blocks can help extend the lifespan of this bathroom feature. The key to ensuring that glass block windows last as long as possible is to have a professional glass block installer place them. Glass block pros will have the skills, tools, and knowledge required to install these special features into any space, noting obstacles like damaged windows or too-cramped areas during the consultation.
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.
