"Andy is a professional contractor. He followed up as promised, and his price was affordable. On the day of the installation, he arrived early with his crew they completed the work and cleaned up afterwards. Additionally, my Zelle only allowed a certain amount per day, but Andy was very understanding allowing me to send the funds as my bank allowed. I will definitely recommend this company to do my renovation work. I am looking forward to working with them in the future. Thank you so much Andy for your honesty, respect and understanding. Happy holidays to you and your family."

Glass Block Windows questions, answered by experts

Glass blocks provide privacy, natural light diffusion, insulation, and a decorative aesthetic.

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

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.

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.

Installation costs range from $400 to $1,500, depending on wall size, design complexity, and labor.
