The cost to install an egress window in Denver ranges from $2,980 to $6,620, with most homeowners paying around $4,640. Your actual cost depends on several factors specific to your home and the Denver-Aurora market.
Cutting through poured concrete requires a concrete saw and is more labor-intensive than cutting through concrete block, which is easier but dustier.
Larger window wells (for deeper basements) need more excavation and a larger galvanized or composite well, adding material and labor costs.
Exterior excavation with a mini-excavator is the largest cost component — accessibility, depth, and soil conditions significantly affect this cost.
The new foundation opening must be waterproofed with membrane, drain tile, and proper grading to prevent water infiltration.
After the window is installed, the interior needs framing, drywall, and trim to finish the window opening, adding $300–$800.
Mountain region costs are rising with population growth. High altitude and variable weather can affect project timelines. Skilled trade labor is in high demand in booming markets.
The cutting starts and suddenly somebody finds a buried receptacle feed, low-voltage wiring, alarm cable, or basement lighting circuit running exactly where the new window opening is supposed to go. I've seen basement projects stop cold because the planned egress location turned out to be carrying much more infrastructure behind the wall than anyone expected.
Basements collect years of rerouted wiring because they're unfinished for so long. Once walls start opening for an egress window, all those old wire paths become part of the project whether the original quote accounted for them or not.
The electrical work itself usually isn't the largest part of the job, but basement bedrooms also trigger much tighter expectations around smoke detectors, receptacle spacing, and circuit protection than homeowners sometimes realize going in.
Budget $106–$424 for permits and inspections. Your contractor typically handles the permit process, but confirm this upfront.
Hiring a pro? Make sure they're properly licensed — see Colorado window installer licensing requirements.
UV-blocking glass is important to protect interiors from sun damage. Consider windows with built-in blinds or external shading for south and west-facing exposures.
This project requires a licensed professional in Denver. Attempting egress window installation without proper licensing can void insurance and create serious safety hazards.

Scheduling during Denver's off-peak season (typically fall and winter) can reduce wait times and may lower costs.
Building code requires an egress window in any basement room used as a bedroom. The window must have a minimum opening of 5.7 sq ft, be no more than 44 inches from the floor, and open without tools. If you're finishing a basement bedroom, an egress window is not optional.
Most egress window installations take 1–2 days. Day one involves exterior excavation, foundation cutting, and window well installation. Day two covers window installation and interior finishing. Weather can affect the timeline for exterior work.
