How much do glass block basement windows cost in Northeast Ohio?
A standard-size glass block basement window typically runs $300–$600 per window installed, and larger or custom openings $600–$1,200. Vents and dryer ports add to it, and the price per opening usually drops when several windows are done on one visit. Our cost guide has the details.
Why replace basement windows with glass block?
Old wood and steel basement windows rot, rust and leak at the frame, and they are the easiest point of entry on the house. Glass block is mortared solid, so it does not rot, does not warp and cannot be pried open. It still lets daylight through.
Can glass block windows still be opened for ventilation?
Yes, with a vent unit built into the panel. A small hopper or dryer vent can be set into the block so you keep airflow. Tell us during the estimate which openings need it.
Will glass block stop the water coming in around our basement window?
It stops the leaks that come through a failed frame, which is most of them. If water is entering because the window well has no drain, the well has to be fixed as well. We look at both so you are not paying twice.
How long do glass block basement windows last?
Decades. Once mortared into the opening there is nothing to rot, rust or warp, which is why we see original installations still sound after thirty years. There is no repainting and no reglazing.
Do glass block windows meet code for a basement bedroom?
No, and that matters. A sleeping room below grade needs a compliant egress opening, which glass block does not provide. For a bedroom you want an egress window, and glass block for the other openings.
How long does it take to replace basement windows with glass block?
Most homes are finished in a single day, since each opening is measured, the old unit comes out and the panel is set and mortared. Cure time is short. We clean up the same day.
Can you replace just one broken basement window or do we have to do them all?
One is fine. Plenty of homeowners start with the window that failed and do the rest later as budget allows, and the price per opening drops when several are done on the same visit. We will lay out both options at the estimate.
