Egress Window Pricing in the Des Moines Metro
Des Moines Egress Windows publishes its prices, because the honest answer to “what does an egress window cost in Des Moines?” is a knowable range, not a mystery that requires a salesman on your couch. A full egress install - permit, excavation, concrete cut, window, code-sized well, and drainage - typically runs $3,500–$6,500 in this metro. Here is every line item, what moves it, and what each suburb’s permit adds.
The full price table
| Job | Typical range | What’s in it |
|---|---|---|
| Full egress install (cut + window + well) | $3,500–$6,500 | Permit, locates, excavation, concrete cut, header/buck framing, R310-compliant window, code well with ladder, gravel drainage, backfill and grading, final inspection |
| Full install, difficult conditions | $6,500–$7,500+ | Same scope with deep dig, tight access, or premium well and cover |
| Window well replacement (existing opening) | $1,000–$3,000 | Remove failed well, re-excavate, new anchored well, drainage bed, backfill |
| Basement window replacement | $400–$1,100 per window | New unit in existing opening - includes glass-block removal where needed |
| Window well covers | $150–$600 | Basic polycarbonate to custom-fit |
| Well drainage repair/upgrade | $300–$1,000 | Gravel bed rebuild, tie-in to footing drain tile or new dry well |
| Permit | $150–$600 | Itemized at cost, varies by city and project valuation |

What moves the number
Foundation type. Concrete block walls cut faster and cheaper than poured concrete - block jobs often land toward $3,500–$5,000, while poured walls typically run $4,000–$6,500. The metro splits predictably: pre-war and mid-century Des Moines (Beaverdale, Highland Park, the east and south sides) is heavy on block and brick-and-block; the growth-ring suburbs - Ankeny, Waukee, Johnston, newer Urbandale and West Des Moines - are almost all poured walls.
Dig depth and soil. The deeper the sill, the deeper the well and the bigger the excavation. Central Iowa’s clay holds water, and Des Moines’ code design criteria put the frost line at 42 inches - the drainage bed has to get below the well floor regardless. Walk-out lots dig shallow and cheap on the daylight side; full-depth basements dig 5–6 feet.
Access. A machine that can drive to the wall saves hours. Fences, decks, mature trees, tight side yards between houses (common on older Des Moines blocks), or hand-dig-only access all add labor.
The window itself. A vinyl slider egress unit is the value pick. Casements open wider per rough opening and suit tighter walls but cost more. Tempered glazing, when the location calls for it, adds per unit.
The well. Galvanized steel is the budget standard; composite and stone-texture wells cost more and look dramatically better from inside a finished room - worth considering when the window is the future bedroom’s main light source. Details on the window well installation page.
Permit costs by suburb - one metro, five offices
The Des Moines metro does not have one building department; it has one per city, each with its own fee schedule, forms, and adopted code edition:
| City | Office | Residential code |
|---|---|---|
| Des Moines | Permit and Development Center | 2024 IRC (adopted eff. Jan 1, 2026) |
| Ankeny | Development Services | 2024 Ankeny Residential Code (locally amended) |
| West Des Moines | Building Inspection Division | 2021 IRC with amendments |
| Urbandale | Community Development Department | 2018 IRC with amendments |
| Johnston | Community Development / Building Department | 2024 IRC (adopted eff. Feb 1, 2026) |
Egress permit fees across these offices generally land in the $150–$600 band depending on how each city values the work. The R310 numbers you have to hit are the same everywhere; what changes is who reviews the plans and how fast. We file with the correct office for your address - which matters in West Des Moines, where the city itself sprawls across Polk, Dallas, Warren, and Madison counties but city hall issues the permit either way.
Sample quotes, illustrated
New-build Ankeny basement, one new opening. Poured wall, open backyard access, standard 5-foot dig, slider unit, galvanized well with ladder and cover: expect the middle of the range, roughly $4,500–$5,500. A second opening cut the same day prices meaningfully below the first - the excavator and saw are already on site.
1930s Beaverdale brick, glass-block window out, egress in. Block-and-brick wall, glass-block removal, sill drop to meet the 44-inch max, header sized for the masonry above, tight side-yard dig: usually $4,000–$6,000, with the measure settling whether the existing opening can be enlarged or a fresh cut is smarter.
Pre-listing compliance fix. An inspector flagged the basement “bedroom” and closing is in five weeks: a code compliance upgrade runs the same install pricing - the premium you pay is urgency in scheduling, not a different rate card.
Well-only rescue. The opening is fine but the rusted corrugated well holds water every spring: $1,000–$3,000 replaced and drained properly, often with a cover added for $150–$600.
Two openings, one Saturday of noise. A Johnston family finishing two basement bedrooms at once: the first cut carries the mobilization at normal full-install pricing, the second - same crew, same excavator, same permit trip - lands meaningfully below it. Per legal bedroom gained, this is the best price in the table, which is why we always ask about the whole basement plan at the measure, not just the wall you called about.
Why this is the cheap way to add a bedroom
Keep the price in context: an egress install is the affordable end of bedroom-adding construction because the square footage already exists. Appraisers count only conforming bedrooms - a basement room without a compliant opening adds little on paper - and going from a 3-bedroom to a legal 4-bedroom typically moves value by more than the $3,500–$6,500 the opening costs. The same math powers basement ADUs: the difference between “storage with drywall” and “legal, rentable living space” is largely the opening in the wall.
What the quote process looks like
- Send the form - a photo of the wall or well helps.
- Free on-site measure: we check foundation type, footing depth, joist direction, utilities in the cavity, grade, and access, and talk through window and well options.
- Flat written quote, permit itemized. No expiration games, no “sign today” pricing.
- We file the permit with your city, schedule around its review clock, and cut when it’s issued.
Fair warning on comparison shopping: a low bid without a permit, a header, or a gravel drainage bed isn’t a lower price - it’s deferred damage, and it’s exactly what city inspectors and buyers’ inspectors catch. Scope-for-scope, we’ll put these numbers against anyone’s. Start with the full install page, browse the FAQ, or send the form for your measure - we cover Des Moines, Ankeny, West Des Moines, Urbandale, and Johnston, and all cutting and installs are done by independent local contractors whose registration you can check with the state.
Frequently Asked Questions
Why is there a price range instead of one number?
Because foundation type, dig depth, and access genuinely move the cost. A block wall with open yard access lands near the bottom of the range; a deep dig beside a deck or a poured wall with tight side-yard access lands higher. The free on-site measure turns the range into one flat number for your wall.
Is the permit fee included in the quote?
It's itemized in the quote at cost - typically $150–$600 depending on which metro city issues it and the project valuation. We file the application with your city's building office and schedule the inspections; you see the fee as its own line, never buried.
Does a second egress window cost less than the first?
Meaningfully, yes, when it's cut in the same visit. The mobilization - machine, saw, crew, permit trip - is already paid for, so a second opening mostly costs its incremental labor, window, and well. Finishing two basement bedrooms at once is the cheapest per-opening way to do this work.
Do you charge for quotes or measures?
No. The on-site measure is free, and the quote that follows is flat. If the smarter answer for your basement is a cheaper service - a window swap in the existing opening instead of a new cut - the measure is where we'll tell you that.
