Edgewater has adopted the 2021 International Residential Code, so a basement bedroom needs an egress window under Section R310: at least 5.7 sq ft of net clear opening, 24 in. high and 20 in. wide, with a sill no higher than 44 in. Wells must be at least 9 sq ft with 36 in. of projection, and need a ladder past 44 in. deep. We set up the project and our local installer cuts the opening, sets the window and finishes the well. Check with Edgewater's Building & Planning team before work starts.

Egress windows in Edgewater
Edgewater is a small city tucked between Sloan's Lake and Lakewood, and many of its homes are older brick bungalows and ranches with basements that were never built as bedrooms. If you want to finish one of those basements, rent out a lower-level room, or just give your family a safe way out, an egress window is usually the first step.
What the code asks for. Under the 2021 IRC, every basement sleeping room needs an emergency escape and rescue opening. Our local installer builds to the same numbers on every job: a net clear opening of at least 5.7 sq ft, at least 24 in. high and 20 in. wide, and a sill no more than 44 in. above the finished floor. Outside, the window well must be at least 9 sq ft with at least 36 in. of projection and width. Any well deeper than 44 in. gets a permanent ladder or steps.
How a project runs. We set up the job with you: we confirm the room, the wall and what the window needs to do. Then our local installer measures, cuts the foundation, sets the window and buck, digs and installs the well, and handles drainage and finish work. Permit paperwork with Edgewater's Building & Planning team is part of the job.

What it costs. Price depends on the wall, the depth of the cut, the window style and the well. See our Denver egress window cost guide for what drives the price.
