"Unprofessional visit. Showed up unannounced and we only knew they were there because one person stood 10 feet from our porch staring at us in through our living room window. My wife spent 10 minutes talking to them, they stated they had no business cards, they only had an appointment card but didn't present it. Honestly when you show up at someone's house you need some sort of identifier if your walking door to door in casual clothes. After the uncomfortable dead stare through the windows my wife and i have decided to post a No Solicitors sign. They didn't take no for an answer at first, pushing with more questions to circumvent the no she gave, as well as interrupted our dinner, as they showed up right at 6pm."

"Kenny and team were amazing to work with - professional, polite, honest, and finished the project ahead of schedule and at a very fair price. We had two old single pane windows replaced in our basement (which may have been 50+ years old), and a new window well installed. The work was very well done. I have since recommended Clifton to multiple friends and other contractors. Five stars."

Glass Block Windows questions, answered by experts

New glass costs anywhere from $3 to $100 per square foot. More specifically, tempered and insulated glass—a common option for sliding glass doors—costs between $10 and $14 per square foot.

Glass block installation can be relatively expensive due to the range of material costs and the labor time to assemble this type of specialty window. The process proceeds slowly as the glass does not absorb moisture from mortar and silicone caulk takes longer to harden, leaving spacers to hold up the structure until the caulk or mortar begins to cure. Plus, if your current windows have structural issues or damage, you’ll need to repair them before beginning the project, increasing your bottom line. 

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

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.

Regular cleaning with non-abrasive cleaners helps prevent buildup and maintains clarity.
