THE SHORT ANSWER
How to Estimate a Basement Egress Window
A 3 ft × 4 ft opening with a standard steel well, excavation and 16 labor hours at $70 totals about $2,490.
Measure the rough opening first
The rough opening size drives both the window unit and the well. A taller, wider cut raises material and the steel well that surrounds it.
- Opening width
- Opening height
- Window unit
- Steel well
Plan the well and excavation
An extra-large or custom well costs more than a standard steel unit. If soil must be removed against the wall, add excavation and disposal.
Watch the access and hours
Interior-only access or a deep foundation wall adds labor hours. Multiply realistic hours by the crew rate, not a generic price.
Get comparable egress quotes
Ask three contractors to break out window, well, excavation and labor. Confirm the clear opening meets code, then use the calculator to check the total.
