What's Causing Your Wet Basement? A Quick Check for Des Moines, IA
A damp corner, a puddle after a storm and water bubbling up at a floor drain in a Des Moines, IA basement can each start somewhere different. Five short questions sort your answers toward one of three next steps. The checker keeps no personal details, and what it gives you is a pointer to follow up on, never a diagnosis.
Before You Start
For each question, choose whatever fits your house best, and pick "Not sure" freely when you don't know. It considers the home's age, its walls, the signs you've noticed, their timing and any earlier fixes. A few answers weigh more: walls of block, stone or brick; water at the wall-floor seam; water through a crack; or a sump that quits or never seems to rest.
Central Iowa's ground plays a part. The last glacier to reach Iowa stopped where Des Moines now stands about 14,000 years ago and left pebbly, clay-rich till behind. Soils formed in that till, such as Clarion, can stay saturated a few feet below the surface from March through June in a typical year, close to basement walls. Summer storms add to it: the National Weather Service counted 5 to 10 inches across northern Polk County on July 2–4, 2026, then 4 to 6 inches around the metro on July 20–21.
What the Result Means
If the result points to a visit, the useful next step is a written estimate. Fill in the request form, after which one independent contractor in the Des Moines area gets in touch, looks over the basement if you agree and sets out in writing what it would do and for how much. Prefer numbers first? The calculator page gives a rough range, and the Iowa rules summary explains contractor registration, plumbing permits and the City's sewer program.
