A basement bedroom is only legal and safe with a proper egress window. We handle the whole job — cutting the foundation, excavating the well, and finishing it clean.
A code-compliant egress window is a real construction job — structural cutting, excavation, and drainage done right so the opening is safe, dry, and to code.
Code is clear: any basement room used for sleeping needs an emergency escape and rescue opening — an egress window — large enough to climb out of and for a firefighter to climb in. Without one, a room legally isn't a bedroom, no matter how it's furnished.
That matters for safety first, but also for your home's value: an unpermitted or non-egress 'bedroom' may not count as a legal bedroom when you sell, and buyers and inspectors increasingly catch it.
There's an everyday upside too. A full egress window floods a basement with natural light, making the whole lower level feel less like a basement and more like a real room.
Most projects combine a few of these into one cohesive lower level — our design-first process makes sure they work together.

Call (720) 340-2032Boulder code & permits. Egress openings are governed by building code and require a permit and inspection, and cutting into a foundation is structural work that has to be done correctly. We handle the permitting and make sure the finished opening meets the size and well requirements that apply in your jurisdiction.
What it costs. As a rough guide, a single installed egress window in the Boulder area typically runs about $2,000 to $5,000, depending on foundation type, excavation depth, and finishes. Soil conditions, the depth of the well, and access all affect the number — so we give you a firm, itemized price after seeing the spot.
We see the actual space, talk through your goals, and measure. No pressure, no charge.
We turn the conversation into a real plan and a clear, line-by-line estimate.
We pull permits and build, managed start to finish by one accountable team.
We confirm every detail with you and hand over a space that's ready to use.
An egress window is a basement window large enough to serve as an emergency escape and rescue opening. Building code sets minimum dimensions so a person can climb out and a firefighter can climb in. It's required for any room used as a bedroom.
Yes. Code requires a compliant egress opening for any basement room used for sleeping. Without one, the room can't legally be called or sold as a bedroom, and it's a genuine life-safety requirement.
Yes. Cutting a new opening into a poured-concrete or block foundation is a standard part of the job. It's structural work that has to be done carefully and to code, which is exactly why it's worth having a specialist do it.
As a rough guide, a single installed egress window typically runs about $2,000 to $5,000, depending on foundation type, how deep the window well needs to be, and finishes. We give you a firm, itemized price after seeing the location.
Most single-window installations take a few days, depending on excavation and foundation conditions. We give you a clear schedule with your estimate.
Not when it's built correctly. A properly sized well with gravel and drainage keeps water away from the foundation, and the window is sealed and flashed against weather. Proper drainage is a core part of how we install them.
