Glass Block Windows in Over-the-Rhine
Over-the-Rhine's Italianate buildings have deep old basements and light wells that were never built for privacy. A mortared glass block panel fits those historic openings, holding the daylight while sealing out the street. Call (513) 657-2471.

Over-the-Rhine
Glass Block Windows for Over-the-Rhine homes
OTR in 45202 is one of the largest intact districts of 19th-century Italianate architecture in the country, and the basement and cellar windows reflect their age. Many open onto the sidewalk or a shared light well, with thin old sashes or grimy glazing that offers no privacy and less security. In a rowhouse this dense, a reachable street-level window is the weak link.
We fit those openings with glass block mortared into the frame, keeping the daylight these deep basements badly need while stopping anyone from seeing in or getting in. There's nothing to rot or repaint, which suits a building you've already put money into restoring. Where a cellar needs air movement, we can set an operable vent into the block so the space breathes without opening up a security hole.
Glass Block Windows
Privacy, Light, and Security in One
Glass block is the practical answer for basements and bathrooms: it brings in daylight, keeps prying eyes and intruders out, and never needs painting. We can add a vent for airflow and even a small dryer vent where you need one.
Want the bigger picture? Pair it with replacement windows or a new entry door, and ask about rolling it into one 0%-for-24-months project. For efficiency ratings, the Energy Star program is a good reference.

Common questions
Glass Block Windows FAQs
My OTR building is historic — will glass block look right in an old Italianate basement opening?
It suits these buildings well because glass block was a common industrial and basement material through the last century. It's low-profile, ground-level, and doesn't touch the character of the upper floors. Most owners choose it exactly because it's tough and unobtrusive on a historic street.
Are glass block windows more secure?
Yes — a mortared glass block panel is much harder to break through than a standard thin basement window, which is why they’re popular for below-grade security.
Can glass block windows open?
The panel itself is solid, but we can build in a small operable vent for airflow, and a dryer vent where the laundry needs one.
Where are glass block windows used?
Most often in basements and bathrooms — anywhere you want light plus privacy and security without a view in.
