"It took me almost 2 years to find a contractor to do glass block in a basement window well where water was coming in. I found D. Karpel Construction thru Angi.com. Mr. Karpel contacted me within 1 hour. A superior contractor. Figured out the problem and in less than 2 days had the job done. A job extremely well done. He is very highly recommended."

"After a long process of trying to get estimates for re-doing my old deck using maintenance free composites, I went w/ Tedesco Construction, as the estimate was realistic and they regularly kept in Touch with me from the very beginning and during the preliminary planning process and all through the project, as this was going on during Covid, with materials shortages,etc. Tom the project manager checked in w me regularly and was attentive to details,as there were some change orders along the way . But now I have a beautiful new deck and am thrilled.Thank you Tom & Tedesco Construction!"

"Called for an estimate and was given a reasonable estimate over the phone. A representative came out to measure. He told me the glass would be ready in a couple of days. It was actually ready the next day!
Two gentlemen delivered the glass and made certain it fit.
Glass looks beautiful.Couldn't be happier with the finished product. Great experience from start to finish.
Highly recommend.

"Dan and his son are an absolute dream come true and no one in our family will ever hire somebody else. Are basement was completely unfinished, and in fact had a lot of our junk all over, and Dan was able to listen carefully to our ideas and thoughtfully make recommendations as to what would work best. The end result is honestly so much better than we ever imagined. Our kids now spend a lot of time in the basement playing games and making memories. We could not be happier with our decision to trust Dan, and in fact we miss seeing him like we did during the project! After finishing our basement, all of our friends asked who was able to do such a good job, and subsequently we've referred Dan and his son to our in-laws and also our good friends for major projects. Look no further, this is the team you are trying to find!"

Glass Block FAQs, answered by experts

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.

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.

Glass block windows typically last for 15 to 30 years, which is slightly less than the 20- to 50-year lifespan of standard windows. You can extend their life by resealing them every few years. Professional installation is also key to ensuring the windows are placed correctly and will function properly for years to come. A professional installer will have the necessary skills, tools, and knowledge to install these features and can identify potential issues like damaged frames or cramped areas during a consultation.

Glass block mortar is the best choice for glass block window units. It is specifically formulated for glass block window installation. Glass block mortar is usually a mixture of Portland cement, sand, and special chemicals. It is a white mortar that is applicable inside and outside your home. Do not use regular tile mortar because it may not have the binding strength and flexibility required for glass block windows.

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.
