Egress Window Cost With Well Installation in Denver: Full Price Breakdown

What an Egress Window Cost With Well in Denver Actually Includes

If you're finishing a basement bedroom in Denver, the egress window is not optional — it's required by code, and it's usually the single biggest line item in the project. The problem is that most online prices you'll find are national averages that ignore the two things that drive cost the most here: Colorado soil and Front Range freeze depth.

At Affordable Egress Co., we've installed egress windows and window wells across the Denver metro since 1999. Below is a straight breakdown of what an all-in egress window cost with well in Denver looks like, and what actually moves the number up or down.

Typical All-In Price Ranges in Denver

For a standard basement egress window with a new window well and grate, most Denver-area homeowners pay between $4,500 and $9,500, with the majority landing in the $5,500–$7,500 range. That figure includes the window, the well, the grate, concrete cutting, excavation, drainage, framing, trim, and labor.

Here's how that total typically breaks down:

• Egress window and buck: $900–$2,200 — code-compliant unit with the required 5.7 sq. ft. of clear opening
• Window well: $1,200–$3,500 — corrugated metal, composite, or poured concrete, sized to code
• Well grate or cover: $250–$900 — required for fall protection in most jurisdictions
• Concrete cutting: $600–$1,500 — depends on wall thickness and rebar
• Excavation and haul-off: $700–$2,000 — driven almost entirely by soil conditions
• Drainage, framing, insulation, and finish: $600–$1,800
• Labor and permits: $700–$1,500

A single window in a straightforward location is at the low end. Multiple windows, deep wells, or difficult access push you toward the top.

Why Denver Pricing Runs Higher Than National Averages

National "average egress window cost" articles usually quote $2,500–$5,000. That's rarely realistic along the Front Range, and here's why.

Soil and bedrock

Much of the Denver metro sits on expansive clay — bentonite-heavy soils that swell when wet and shrink when dry. Digging a well in that material requires over-excavation and proper backfill, not just a hole in the ground. In foothills-adjacent areas like Golden, Littleton, and Arvada, you can hit claystone or sandstone shelves that require a rock saw or breaker, which adds hours and cost.

Freeze depth and drainage

Colorado's frost depth runs roughly 30 inches in the Denver area. Window wells here need to drain to daylight or to a gravel-and-drain-tile system that discharges below the frost line — otherwise you get a well that fills with ice and meltwater every spring. Cheap wells that skip this step are the number-one cause of wet basements we get called to fix.

Code requirements

Denver and most surrounding jurisdictions follow the IRC egress rules: a minimum 5.7 sq. ft. of clear opening, a sill no higher than 44 inches from the floor, and a well that allows the window to fully open. If the well is deeper than 44 inches, it needs a permanently affixed ladder or steps. Local inspectors also want to see a grate or cover rated for the load. These aren't upsells — they're what gets your basement bedroom to pass.

What Changes Your Quote the Most

1. Well depth and material. A shallow corrugated well is the cheapest option. A deep poured-concrete well with an integrated ladder costs significantly more but lasts decades and looks better against a finished exterior.
2. Wall type. Poured concrete cuts cleanly. Block foundation walls take longer and sometimes need additional structural framing.
3. Access. If the excavation crew can't get a mini-excavator to the wall, everything is hand-dug. That's real labor.
4. Finishing level. A drywall-ready rough-in costs less than a fully trimmed, painted, insulated opening that matches your existing basement.
5. Number of windows. Two or three windows at once almost always beat the per-window price of doing them one at a time.

What to Expect From the Install Itself

Most of our installs are completed in a single day. We cut the foundation wall, excavate and set the well, install the window, tie in drainage, and leave the site clean. Finish work like drywall patching and trim may extend into a second visit depending on your scope.

We've been doing this since 1999, we pull the permits, and we build to inspection the first time. We also handle window well replacement for homeowners whose existing wells are rusted, undersized, or failing to drain — a common issue in older Denver neighborhoods.
