Egress Window Costs
What egress windows actually cost in Denver.
No bait pricing. Here's the real all-in cost range for Denver egress window projects in 2026 — and what changes the number.
Typical Denver pricing
| Project type | Typical Denver range |
|---|---|
| Single egress window, poured concrete | $4,500 – $7,500 |
| Single egress window, block foundation | $5,000 – $8,000 |
| Window well replacement only | $1,200 – $2,800 |
| Walkout basement door conversion | $15,000 – $35,000 |
| Drainage repair / regrade | $800 – $3,500 |
What drives the number
- Foundation type. Poured concrete is straightforward; CMU block and old brick foundations cost more and may require an engineered header.
- Excavation depth & access. Deep wells, tight side yards, and landscaping protection all add labor.
- Window brand & glazing. A code-minimum casement is the baseline; high-end Marvin or Andersen units, low-E glazing, and grilles add cost.
- Drainage tie-in. A clean tie-in to an existing perimeter drain is cheap. Trenching to a daylight outfall costs more — and is usually worth it.
- Permit jurisdiction. City of Denver, Jefferson County, Arapahoe County, and Adams County all charge differently. We itemize this.
- Finished basement demo & repair. Cutting through a finished basement adds drywall, paint, and trim work back into the scope.

What's actually included in a Denver install
Every full egress window install we quote in Denver covers the same scope: engineering review, building permit, utility locates, mini-excavator excavation, diamond-saw concrete cut, code-sized casement window, galvanized or composite window well anchored to the foundation, deep gravel drainage tied to your perimeter drain, interior trim, exterior flashing, and a final inspection. Walkout door projects add the engineered stairwell and a full-size insulated walkout basement door. There are no separate permit fees, dumpster fees, or "drainage upgrade" line items added later — the price you see is the price you pay.
FAQ
Cost questions.
Two reasons: foundation type and soil. Most Denver basements have poured concrete walls that require diamond saw cutting, and our expansive clay soil and freeze-thaw cycles demand engineered drainage. Both add cost — but skipping them is what causes the failures we get called to fix.
