Egress Window Installation in West Des Moines, IA

West Des Moines is two housing markets wearing one city name, and Des Moines Egress Windows works both: the pre-war and mid-century blocks that grew out from Valley Junction, where basements have small high windows that never counted as exits, and the newer poured-foundation neighborhoods rolling west past Jordan Creek into Dallas County, where builders installed one egress opening and left the rest of the basement to you. Both end up needing the same thing - IRC R310-compliant openings - for opposite reasons.

One fact about this city surprises even locals: it sprawls across four counties - Polk, Dallas, Warren, and Madison. That matters for taxes and schools, but not for this work: building permits for every West Des Moines address go through the city’s own Building Inspection Division, which enforces the 2021 IRC with local amendments. We file there, whichever county your parcel sits in.

The east side: Valley Junction and the mid-century grid

The historic core around Valley Junction and the blocks east of 63rd carry housing from the early 1900s through the 1960s - block and brick-and-block foundations, low ceilings, and original basement windows sized for coal-era ventilation, not escape. Typical finds: hoppers up near the joists with sills far above the 44-inch code maximum, glass-block infills from mid-century “upgrades,” and rusted corrugated wells with no drainage bed underneath.

Making a bedroom down there legal is enlargement work: glass-block removal or hopper tear-out, sill drop, new header, buck frame, egress unit, code well - usually at the friendlier end of the $3,500–$6,500 range, because block walls come out course by course instead of demanding hours of wet sawing. Many of these houses have no footing drain tile, so wells here get the deep gravel dry-well treatment; it’s exactly the situation well drainage work exists for.

The west side: Jordan Creek and the Dallas County growth ring

West of I-35, the story flips to new construction: poured walls, 9-foot basements, sump systems and footing tile, one builder-installed egress window, and unfinished square footage waiting for bedrooms. The math is the metro standard - every new sleeping room needs its own compliant opening (5.7 sq ft net clear, 24” × 20” minimums, 44” max sill) - and cutting the second and third openings in one mobilization prices meaningfully better than spreading them out.

These are the most predictable installs we do: clean concrete, drain tile to tie into, and lot access an excavator likes. The recurring west-side catch is settled backfill - a decade of clay settling can tip the builder’s grading back toward the foundation, so every well we set or service gets the grade checked and corrected as part of the job.

Why West Des Moines basements get finished

The drivers here are the metro’s, concentrated: radon and resale. Iowa is entirely EPA radon Zone 1 - roughly 70 percent of tested homes exceed the action level - so West Des Moines basements get mitigation systems as standard practice, and a mitigated basement is a basement someone will finish and sleep in, which triggers the egress requirement room by room. And in a market with this much turnover, the bedroom count does heavy lifting: appraisers only count conforming bedrooms, and a flagged basement “bedroom” near Valley Junction or in an early-2000s Jordan Creek-area finish becomes either a pre-listing compliance fix on your schedule or a repair-addendum fix on the buyer’s. Sellers who move first keep the count and the leverage.

Basement ADUs are the growing third driver - with the city’s rental demand, a legal basement suite needs compliant escape openings in every sleeping room before anything else about it is legal.

Practical notes for your project

• Permit and timeline. We file with the Building Inspection Division, itemize the fee at cost ($150–$600 metro-wide is typical), and build the city’s review clock into the schedule. Never a guaranteed approval - that belongs to the city - but a handled process, start to sign-off.
• Season. Excavation runs roughly April–November against the area’s 42-inch frost depth. Winter is for measures, quotes, permits, and window swaps in existing openings.
• Pricing. Same published ranges as everywhere we work - the pricing page has the full table, and the quote after the free measure is flat.

Send the form with a photo of your wall or well - Valley Junction vintage or Jordan Creek new. We also cover Urbandale next door, Johnston, Ankeny, and all of Des Moines proper, and the cutting and installs are performed by independent local contractors.
