"I needed stucco repair work on an old chimney (and other spots). Grady was meticulous and thoughtful on what approaches and materials would work. Throughout the project they allocated sufficient time for each treatment to cure and inspected the work before proceeding to the next step. Grady started the project with no money down and only required ongoing payments for materials until the project was well underway. The final payment was due only after they did a final inspection. Total project cost was also below other bids."

"Bob and his team did an excellent job. I waited awhile before posting my recommendation because I wanted to make sure that their work lasted and was completely 100% durable. They not only did great with Mold Removal caused by another negligent HVAC company, they also replaced the affected drywall areas along with carpentry services. Do yourself a favor and hire Bob and his team.....best of all is that they're a family business as well and they're a delight to have in your home. They're also very conscious about cleaning up after themselves. I would definitely hire them again....you should too!"

Glass Block FAQs, answered by experts

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.

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.

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 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.
