Egress Window Installation in Maize, Kansas

Maize is the fastest-growing suburb in the Wichita metro, and nearly all of that growth is new single-family houses on poured foundations with big, deep, unfinished basements. That makes Maize, house for house, one of the strongest egress markets in Sedgwick County: those basements are being finished right now, and every new bedroom down there needs its own opening built to the code MABCD enforces. Full installs run our published $3,500 to $6,500; the permit routes through the City of Maize to MABCD, which handles plan review and inspections for the city under contract.

The numbers behind the growth

Maize had 1,520 people in 1990, 1,868 in 2000, 3,420 in 2010, 5,735 in 2020, and an estimated 7,059 in 2024, a 67.7 percent jump in the 2010s and another 23 percent since. The town began growing in 1950 and has since been absorbed into Wichita’s northwest sprawl along K-96; Maize USD 266 now runs eighteen schools in and around the city. Most of the housing is under twenty years old.

The Maize basement, specifically

Walk an unfinished basement in one of the newer Maize subdivisions and you usually find the same setup: poured walls, one egress window with a well (the escape opening the original permit required), plumbing rough-ins for a future bath, and a large open floor. Builders size to the plan, not to your plans. Finishing that space into two bedrooms and a rec room means each sleeping room needs its own compliant opening: under the Wichita/Sedgwick County amendment, 4.5 square feet net clear with a 5.7-square-foot break-out area (we size to clear 5.7 outright), a sill within 44 inches, a 9-square-foot well projecting 36 inches, a ladder with rungs 12 inches on center past 44 inches of depth, a rated cover past 30, and 12 inches of gravel under the well. The egress installation page walks the build; two openings in one visit price meaningfully better than two separate projects.

Two things we check before quoting a cut in Maize. First, the builder’s existing opening: some meet the amendment, some were sized to an older reading, and a well with rungs at 18 inches or no rated cover is a cheap fix, not a new window. Second, whether the builder left a second rough-in in the wall, which happens and saves the concrete work entirely.

Settled backfill

Most of Maize’s housing is young enough that the original backfill around the foundation is still settling. We routinely find grading that has sunk into a slope toward the house, so every well we install or service here gets the surrounding grade checked and corrected, because a code-perfect well in a bowl of settled Group D clay is still going to collect water. The soil under Maize is the same Goessel and Rosehill silty clay as the rest of the county, 35 to 55 percent clay, and NOAA’s normals put over ten inches of rain on May and June together. The drainage page explains why the 12-inch gravel rule is a floor, not a design.

Permits: Maize is an MABCD town

Maize contracts with MABCD for building services. You contact the city to start the permit, the building application and plans go to MABCD through its portal, MABCD does the plan review and the inspections, and the contractor must carry an active MABCD licence. In practice that means a Maize job runs on the same code, the same fee table, and the same inspectors as a Wichita job, with the city as the front door. Details on how the permit fits the budget are on the pricing page.

Radon and the finishing sequence

Sedgwick County is EPA radon Zone 2; in the Kansas Radon Program’s 2010 county data, 30.9 percent of measurements came in at or above the 4.0 action level. New construction is not exempt. Cut the openings first, test second, and finish third; the bedroom conversion page has the order and the reasons.

Selling in Maize? Count the bedrooms

Maize’s resale market carries a lot of “four bedroom” listings where the fourth is in the basement. If that room’s window does not meet the amendment, a buyer’s inspector will find it. A code and permit upgrade before listing keeps the bedroom count and the leverage; the same fix under a repair addendum happens on the buyer’s timeline instead.
