Radon mitigation in Ames & Story County
Story and Boone county mitigation runs into two distinct conditions: flat Des Moines Lobe till that does not pass suction easily, and a near-campus rental stock whose slabs have been cut repeatedly for added plumbing.
Ames pairs a large student-rental sector near Iowa State with owner-occupied neighborhoods of postwar ranches and 1990s-forward subdivision colonials on poured basements. Nevada, Huxley, Gilbert, and Story City are small-town Iowa with older cellars and newer infill. Boone is an older railroad town with a deep stock of 1890s–1930s housing on block and stone foundations.
What mitigation involves here
On the till, the question is whether one suction point reaches across the slab. Where a drain-tile loop feeds a sump, it usually does; where a slab sits directly on tight native till, the contractor may need an excavated pit beneath the point to create a plenum, or a second point entirely. On converted rentals, sealing is structural to the design — floor-wall joint, penetrations from added bathrooms and kitchens, abandoned floor drains, and a gasketed sump lid. A system over an unsealed converted slab runs without holding the pressure it needs. Flat lobe till drains poorly, so drain tile and sump pits are standard in newer construction and a frequent retrofit in older housing. Poured walls dominate post-1970 building; the older Ames and Boone stock is block and stone with slabs frequently poured over native till. Student-rental conversions added plumbing penetrations that were rarely sealed afterward.
Deciding whether you need it
Whether a specific house in Ames & Story County needs a system is settled by a measurement at that address, never by a county map — EPA recommends fixing at 4 pCi/L and considering action between 2 and 4 pCi/L. Requests from Story and Boone route to independent businesses that hold a current Iowa radon mitigation certification, which you should verify is current before you sign anything. Story and Boone counties sit on the Des Moines Lobe, the youngest glacial landscape in Iowa — Wisconsinan till laid down roughly twelve to fourteen thousand years ago, flat, poorly drained, and pocked with the closed depressions that once made this prairie-pothole country. The Des Moines River has cut a deep valley through Boone County, exposing the section and creating a very different setting on the valley slopes.
Who may legally do the work
Iowa certifies radon measurement and mitigation specialists through its state health department. The credential is Iowa-specific — not a general contractor license, and not a university or municipal registration, neither of which exists for radon work. Verify it directly before hiring.

Radon Mitigation questions in Ames & Story County
I am about to finish my basement. Should the system go in first?
Yes, and it will cost you less. An open basement lets the contractor put the suction point where a pressure-field test says it belongs, run pipe along exposed joists, and seal the slab perimeter while it is reachable. After drywall, the routing gets compromised and the sealing gets partial. Mitigating first also means you are finishing a space whose number you already know.
What makes mitigation different in Ames & Story County?
Subdivision basements in Ames, Huxley, and Gilbert are easy to work in. Near-campus rentals are harder: finished lower units, tight lots, shared drives. Boone’s older housing has usable side yards and light appearance constraints. Properties on the Des Moines River valley slopes in Boone County present walkout and partially buried foundations.

Your request goes to no more than three independent businesses serving Ames & Story County, each holding a current Iowa radon mitigation certification, and each quotes you directly. The contract, the price, the schedule, and the warranty are between you and the contractor you pick.
