"Contractor was very professional and did an excellent job. Glass has a coating to help prevent water spotting. I also have the option of adding a custom shower door if I decide I need one at a later date. Price is very competitive. Very happy with the job."

Glass Block questions, answered by experts

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

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.

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

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.

Glass walls are more expensive overall than their brick or drywall counterparts. However, if you need walls for a building with more than two or three stories, glass walls are the more budget-friendly option.
