Egress Windows
An Egress Window Is a Foundation Job
An egress window is a basement window big enough to climb out of in an emergency and for a firefighter to get in. Building code requires one in every basement bedroom, and many homeowners add them simply to turn a dark lower level into bright, comfortable living space.
What most people don't realize is that it means cutting a brand-new opening through your foundation wall. Done wrong, it can weaken the wall or create the newest leak in your basement. The opening has to be sized and finished correctly, and the window well outside has to drain.
That's why it makes sense to have basement specialists do it. We've been working on Milwaukee-area foundations since 1981, and we handle every part of the project, from cutting the opening to setting the well and connecting the drainage.

What Makes It Egress
The Three Parts of a Code-Compliant Egress Window

Code sets a minimum clear opening when the window is fully open. Most original basement windows are far too small.

The bottom of the opening can't be too high off the floor, which often means cutting lower than the old window.

The well has to be big enough to climb out of, and deeper wells need a ladder or steps.

Code is only part of the story. Here's why so many basements get one.

How We Fix It
Our Egress Window Installation
OpeningCutting & Finishing the Opening
We saw-cut the opening through the foundation wall at the size and height your window needs. Poured walls are cut cleanly with specialized saws, and block walls are cut, then the open cores are filled and finished so the edges are solid.
We plan the location around the framing above, any utilities in the wall and the space outside for the well, and we make sure the wall around the opening stays structurally sound.
The finished opening is square, clean and ready for a properly sealed window.

WellWindow, Well & Drainage
The window is set and sealed into the opening, and the well is installed outside on a gravel base. Where possible, we connect it to drainage so rain and snowmelt have somewhere to go besides your new window.
Deeper wells get a built-in ladder or steps, and a clear cover can keep out leaves, snow and critters while still opening from inside.
When we're done, you've got more light, a safe way out and no new leak.
