An egress window gives a below-grade space a code-compliant emergency exit, one large enough to climb through, with a well that drains and a sill low enough to reach. In Iowa and Missouri, any basement bedroom or sleeping area is required to have one, and the window has to meet specific size and operability standards to qualify. For homeowners finishing a basement or replacing an aging window that no longer meets current standards, getting the installation right matters from the permit stage through final inspection.
We believe in providing everyone with the same fair affordable pricing, ensuring hassle-free, budget-friendly solutions.
We offer the industry's longest honored warranties. Our warranties provide exceptional protection that others can't offer.

Iowa follows the International Residential Code for egress window standards. Every basement bedroom or sleeping area needs at least one operable emergency escape opening, and each sleeping room in a basement requires its own. The window has to open from the inside without tools, keys, or special knowledge.
To meet Iowa's code, the window opening has to clear these minimums:
Width and height minimums don't automatically add up to the required area. A window that hits 24 inches by 20 inches falls short of 5.7 square feet, so the actual opening dimensions need to be calculated against the area requirement, not just checked against the individual minimums.
Where the sill sits below grade, a window well is required. The well has to be at least 36 inches wide and 36 inches deep, with drainage connected to the foundation drain system. If the well is deeper than 44 inches, it needs a permanent ladder or steps built in.
Local municipalities can amend these standards, so the requirements for your specific address get confirmed before work begins. Anchored Walls pulls permits and works with local inspectors across our Iowa and Missouri service area, so the finished installation meets the code that applies to your home.
Installing a new egress window starts outside the foundation. The crew excavates along the wall to expose the area where the well will sit, cuts the opening through the foundation, and frames it to carry the load above. From there the well goes in, drainage gets tied into the existing system, and the window is set, sealed, and tested. The interior side gets finished and cleaned before the crew leaves.
How involved each step gets depends on your foundation. Poured concrete, concrete block, and stone each cut differently and require different framing approaches. Basement depth affects how much excavation is needed and how tall the well has to be. Soil conditions across central Iowa vary too, and what's easy to dig in one part of Des Moines can be considerably harder a few miles away. The estimate accounts for all of that before any work is scheduled.
Here is what the process looks like from inspection to finished window:
Anchored Walls pulls permits before digging begins and coordinates with local inspectors through final sign-off. We don't consider the job finished until the work has been reviewed and approved.
Not every call is for a new installation. Window wells rust, crack, and lose their drainage over time. Frames corrode. Older timber wells rot through Iowa's freeze-thaw cycles until the structure fails. Windows installed before current code was adopted may not hit today's size requirements, and a window that passed inspection fifteen years ago might not pass one today if the opening has been painted shut or the well has settled.
Anchored Walls handles the full range of replacement and rehabilitation work. Damaged or deteriorated wells come out and get replaced with properly draining alternatives sized to current Iowa code. Timber wells get swapped for permanent options that hold their shape through repeated freeze-thaw cycles. Where undersized utility windows don't meet egress requirements, we replace both the window and the well. We also repair failed well drainage, clearing blockages and reconnecting to the drain tile system where water has been pooling at the foundation.
If you're not sure whether your existing window meets current Iowa code, the free inspection is the right place to start. We'll measure the opening, check the well, and tell you what you're working with before any work is scheduled.
Anchored Walls has been doing foundation and basement work in Iowa and Missouri since 1978. That history means we have worked on the range of foundation types, soil conditions, and basement configurations across this region, and egress window installation and replacement is a regular part of that scope.
Every installation is backed by a lifetime transferable written warranty and a money-back guarantee. We hold an A+ rating with the Better Business Bureau and a 4.8 out of 5 across more than 2,000 reviews. Our crews handle the full job, and we pull permits and coordinate with local inspectors before any work begins. We don't consider a project finished until it passes inspection.
Whether you're adding a new window for a basement remodel or replacing one that no longer meets Iowa's current standards, the free inspection is where the work starts. We'll assess your foundation, measure what's there, and walk you through your options before anything is scheduled.
