Many Columbus-area basements have original windows that are too small or too high for emergency escape. Replacement for egress often means cutting a larger opening, not just swapping glass in the same rough opening.
When enlargement is needed
- Net clear opening is below code minimums
- Sill is higher than the maximum allowed above the finished floor
- Only half of a slider opens, so the clear path is too narrow
- You are converting the room to a bedroom or finishing habitable space
