Limits on the information about foundation movement, soil behaviour and repair methods published by Des Moines Foundation Pros.

General information only

Everything here is general information about foundation movement, soil behaviour and repair methods in and around Des Moines. It is not an inspection report, an engineering opinion, or advice about a specific property.

Where the figures come from

Climate, soil and code figures on this site are drawn from U.S. Census ACS 2020-2024 via Census Reporter; U.S. EIA RECS 2024 state structural characteristics; NOAA NCEI 1991-2020 Climate Normals (USW00014933); Iowa Geological Survey, Des Moines Lobe landform page; USDA NRCS SSURGO Polk County (IA153) via Soil Data Access; NWS gauges DEMI4, DESI4, DOSI4, DFMI4 and the NWS Flooding in Iowa page; OpenFEMA declarations; Iowa Department of Public Health radon fact sheet and U.S. EPA Iowa radon zone map; Iowa Code chapter 91C and the Iowa DIAL contractor registration page; City of Des Moines Private Property Protection Program page (all fetched 2026-11-11). Sources are cited so they can be checked rather than taken on trust. Code editions change and adopting jurisdictions amend provisions, so anything decisive should be confirmed with the authority that will inspect the work.

Cost figures

Ranges are typical figures, explained on the cost guide, and are illustrative rather than quotations. What a particular job costs depends on access, condition and scope, none of which can be known from a web page.

Licensing

Verify any contractor on Iowa's own licensing register rather than relying on a number printed on a website or a vehicle.

No guarantee of outcome

Work addresses the conditions found at the time: a repair stabilises what was measured on the day; soil moisture keeps moving afterwards and a structure can continue to adjust. Warranty terms, where offered, appear in the written scope and are the only commitments that apply.
