"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."

"EJALE Group, in the person of Evol Ewan, was extremely responsive. Evol made a site visit the same day I first called him. He is very professional, knowledgeable, friendly, courteous, listens well, and takes time to explain and answer questions. We hired EJALE Group to do site prep and pour a concrete slab to receive a 2-car garage (by others). Our builder, who has very high standards, referred us to Evol and said his work was top-notch. The team performed excellent work in terribly hot and humid conditions. We'll hire EJALE Group for our next projects."

"I'd used this vendor before to replace my sidewalk and repair (using Ardex) concrete crumbling of an exterior back step.  As they did a good job, this seemed a safe choice.  While they did a good job on this as well, it took forever to get on the schedule.  Although I paid the initial deposit on 3/29, the work wasn't perfomed until 5/20, and only then because I made an issue of it.  It rained torrentially in April and May so crews were available for indoor work.  The problem seemed to be that I needed to be home and I needed two days notice for my employer.  These guys normally work when the owner is absent.  Although Legacy proposed that I essentially "leave a key under the mat" to provide increased flexibility, I didn't really feel comfortable with that.  While I believe that Legacy is trustworthy, the contractor couldn't be responsible for things that occurred once they left the property.  In any case, the repair solved the problem, though the actual work took about two hours (vs. the four in the original estimate). "

"Very well done project master bath expansion consisting of complex air tub/shower installation and extensive tiling. Marble tile installation was strong point - over a year of heavy use and no cracks anywhere. Contractor was responsive even when work slowed an called/came back personally to touch up few minor areas in dry wall several months after work was completed."

Glass Block questions, answered by experts

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

Although glass block windows are made of multiple layers of thick glass, they can still break. If an individual block shatters, it can be removed and replaced, but this is a job for a window repair professional. The project is often complex and may require breaking the block further for removal. Do not attempt to handle it yourself, as the broken glass can be dangerously sharp. A professional will have the necessary tools and expertise to replace the broken glass block quickly and safely. Before hiring, confirm that the repair pro has experience with this specific type of window.

Heavy glass tends to be more expensive than thin glass because it is stronger and more durable. In most cases, ¼-inch-thick glass is ideal for mirrors, and ⅛-inch-thick glass is ideal for residential windows. Heavier glass isn’t always necessary, and can be more challenging to hang or install. Work with a local window installation pro for replacement or new construction windows.

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.

Yes, professionals can install decorative or colored glass block patterns for a unique look.
