Glass Block Basement Windows in New Lenox
Boom-era New Lenox subdivisions were built with thin vinyl and aluminum basement windows. Two decades on, most are leaking air, fogging, or seizing shut.
-
No Seal Left to Fail
Vinyl and aluminum basement windows fail at the seal. Mortared block has no seal, no sash, and nothing that loosens over two decades
-
Fits the Original Opening
Each panel is built to the opening the builder framed, so nothing gets filled in or furred out to make a stock size work.
-
Fresh Air Without a Sash
A built-in vinyl hopper vent moves air through the basement while the rest of the panel stays sealed.
Glass Block for Finished New Lenox Basements
A finished basement changes what a window has to do. It's living space now, and it needs to be dry, secure, and private.
-
No Sash, No Track, No Way In
There's no sash to force and no track to pry. A basement slider is a weak point; mortared block isn't one.
-
Daylight in a Finished Room
A finished basement needs light without turning the room into a display case. Frosted block brings daylight in and keeps sightlines out.
-
Moisture Control for Finished Space
A sealed masonry unit stops seepage at the window opening, a common moisture source in finished basements.
