Common questions
How much does foundation repair cost in Des Moines?
National 2026 guides put a typical project at $2,200–$8,200 (Fixr), with This Old House averaging $5,179. Injecting one crack is $200–$1,000, bracing a bowing wall $4,000–$15,000, and each steel pier $1,000–$3,000. No public source tracks Des Moines prices, so treat these as yardsticks.
Why does my basement leak every spring?
Spring stacks snowmelt on top of the wettest weeks of the year: about 14.5 inches of precipitation falls from April through June at Des Moines International Airport (NOAA). Polk County soils often hold a saturated zone near the surface (USDA NRCS), so groundwater presses at the floor joint until drain tile or a sump relieves it.
Is a stair-step crack in a block basement wall serious?
It can be. Stair-step cracks through mortar come from either soil pushing the wall in or a corner settling. Hold a level against the wall: if it leans in at the top, or the crack is widening, have it assessed before the next wet season.
Will a sump pump alone keep my basement dry?
Only if water can reach it. A pump empties a pit; drain tile along the footing is what collects groundwater and carries it there. Where the only water is from a short downspout or a low spot in the yard, fixing that may be enough without a pump at all.
Do Iowa foundation contractors need a license?
Iowa requires registration rather than a foundation license. Under Iowa Code chapter 91C, anyone earning $2,000 or more a year from construction must register with the Department of Inspections, Appeals, and Licensing, which runs a public search. Plumbing contractors also need a separate state plumbing license, and the city's sump-rerouting program requires a licensed plumber.
Should I test for radon after basement repairs?
Yes. Every Iowa county is EPA Radon Zone 1, and the state's average indoor level is 8.5 pCi/L, against 1.3 nationally (Iowa Department of Public Health). Cracks, hollow block and sump openings are common entry points, so a test after sealing or drainage work shows where you stand.
Is the first visit free?
It depends on the company. Many local specialists don't charge for the first visit; ask when they call, before they come out.
