"Margaret is artist, repaired 8â x12â curved glass piece in a 4â x6â window 10 feet in the air above our front door. While others told me the window would have to be removed, taken to shop, disassembled, repaired and reinstalled with costs as high as $3000. Margaret did the job for far, far, far less! Margaret, thanks again, Mel"

"GoodFellas did the master and guest bathroom in our home. My wife and I are expecting a child in Nov and wanted to get as much work done on the house before the baby was born. GoodFellas was able to finish the work in a timely matter and exceed expectations. Even though the company is handling multiple jobs at a time, they are able to make us feel like were the only ones, giving us complete attention when needed. They aren't cutting corners so it is well priced for the quality you get. Our project manager was there when we needed him including picking out the tile, glass and marble.

"I needed several things done: 1) Repair a broken anchor that secured shower glass to a half wall. 2) Replace the silicone caulking around the shower glass 3) Adjust shower door so it no longer grazes the half wall upon closure 4) Replace the door sweep They were very responsive in the initial visit to look at the problem and suggested just recaulking to secure the glass. I rejected that idea, as I didn't think it would hold for very long. They made an appointment to return a few days later. They arrived at 10:10 am, made all the repairs and left by 11:40 am. I thought the $800 price was a little steep and there were a few very minor issues, but overall the quality of the work was decent. The minor issues were as follows: 1) There was a lot of old silicone caulk scattered around the room after they left. I'd have liked them to vacuum the room. 2) There were a few places where the silicone was got on the marble and on the metal framing."

Glass Block Windows FAQs, answered by experts

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.

DIY is possible for small projects, but professional installation ensures proper sealing, structural integrity, and a precise finish.

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.

Installing glass block windows has benefits and disadvantages, as with most materials. The pros and cons can vary depending on the type of glass block and the window location.

Pros

  • Maintains privacy while letting light into the bathroom

  • Energy efficient

  • Sealed to prevent drafts

  • Aesthetically pleasing

  • Strong and secure

Cons

  • Costly to install

  • Challenging installation

  • Challenging repair

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.
