How to replace steel frame hopper basement widows in concrete with vinyl replacement widows?

Re-design6 years ago
How were the original windows installed? Were they cast in place or installed after the walls were built? Makes a huge difference.

I beleve they were cast in place.
If they were cast in place then they probably have anchors that hold them in the wall. These anchors will have to be cut or chipped out. Get a bid for replacement windows and see what they say. Vinyl replacement windows are custom made to fit the openings.
