Egress Window Cost by Type
Last updated
No installed egress window prices are published here because none had a citable source, but window type changes how big a rough opening, and so how much concrete cutting, the job needs.
No installed prices are published here. We only print figures with an official or citable source, and none was found for installed egress windows in the Denver metro. Permit fees are official, so they're listed below.
How the window type affects the job
Every type has to deliver the same opening: at least 5.7 sq ft clear, 24 in high, 20 in wide, sill no more than 44 in above the floor (Jefferson County R319). That affects how big a rough opening, and so how much concrete cutting, each type needs:
| Type | How it opens | Effect on size |
|---|---|---|
| Casement | Swings fully open on a side hinge | Most of the frame counts as clear opening, so it can meet the minimum in a smaller rough opening |
| Sliding (glider) | One sash slides past the other | Only the moving sash counts, so the frame must be larger |
| Single/double-hung | Sash slides vertically | Only the open half counts, so it needs a tall frame for the 24 in height |
| Egress door | Swings open full height | See egress window vs. door |
Other cost drivers
- Foundation type and thickness, and whether you're enlarging an opening or cutting a new one (concrete cutting).
- Well depth: over 44 in requires a ladder or steps (Jefferson County).
- Covers, drainage, excavation access and landscape repair (cover options).
- Historic design review in Denver (Denver Landmark).

Frequently asked questions
Why are no installed prices listed?
We only print figures with an official or citable source, and none was found for installed egress windows in the Denver metro.
Which window type needs the smallest opening?
A casement swings fully open on a side hinge, so most of the frame counts as clear opening and it can meet the minimum in a smaller rough opening.
Why do sliders and hung windows need bigger frames?
On a slider only the moving sash counts, so the frame must be larger. On a single- or double-hung window only the open half counts, so it needs a tall frame for the 24 in height.
What other factors drive cost?
Foundation type and thickness, enlarging vs. cutting a new opening, well depth (over 44 in requires a ladder or steps), covers, drainage, excavation access, landscape repair, and historic design review in Denver.
