"They look great! The installation process took less than 10 minutes. I am so happy with my frames, they cost $800 less than I would have paid had I had the builder install them. I will definitely recommend this company in the future, and use them again should I need new frames!!

"The job was performed in two phases, first the shower, than a few days later, the windows. In both cases, Enrique and Isaac showed up on time. They did an excellent job in all aspects of the work. I should note that Raintree's price was the low bidder of three bids. The promptness and quality of work was superb. I highly recommend Raintree for Glass work. I would not hesitate to have them do additional work at my house."

Glass Block FAQs, answered by experts

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

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.

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

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.
