Radon Testing & Mitigation in West Des Moines, IA

West Des Moines radon projects typically invoice $150 to $2,500, with measurement tests at $150-$250 and full ASD mitigation on the city’s affluent newer-construction housing stock — much of which carries RRNC passive piping that converts to active mitigation for $500-$900 — running $800-$2,500 depending on whether passive pre-piping exists.

A short-term test runs $150-$250. Long-term alpha-track is $50-$150. Passive-to-active conversion on an existing RRNC stub runs $500-$900 (just install the fan, seal connections, label the system, and verify). Full ASD retrofit on pre-RRNC homes runs $1,200-$1,800. Larger Jordan Creek custom homes with multi-zone foundations can push to $1,800-$2,500. Post-mitigation verification is $150-$200. Cost data from HomeAdvisor, Angi, and AARST-NRPP regional surveys.

Real estate and West Des Moines homeowners

West Des Moines is one of the more affluent and newer-construction-heavy markets in Iowa, and RRNC passive piping has been increasingly standard in city subdivisions since the mid-2010s. The Iowa Association of Realtors radon rider applies to West Des Moines listings. For a buyer purchasing a newer home, the disclosure question becomes: was RRNC piping installed, was a fan ever added, and what does the current test show. A pre-listing test on a newer home can confirm RRNC is performing passively below 4 pCi/L or signal that an inexpensive fan upgrade is needed. Standard Iowa homeowners insurance does not cover mitigation.

How to choose a radon contractor in West Des Moines

Verify IDPH license status at idph.iowa.gov
Confirm NRPP or NRSB credentialing
Confirm general liability and workers’ comp
For RRNC conversion, get the proposal in writing with the existing-stub inspection, fan model, integration with the existing chase, manometer location, verification schedule, and warranty
Ask whether the contractor has experience converting passive RRNC stubs to active systems — this is faster and cheaper than full retrofit and is a growing share of West Des Moines mitigation work
Save installation photos, manometer reading, and post-mitigation report

Frequently asked questions

How do I know if my West Des Moines home has RRNC passive piping?

Look in the lowest-level mechanical space or basement for a vertical PVC pipe (typically 3 or 4 inches in diameter) running from the slab up through the home toward the attic and roof. If the pipe is capped, labeled 'radon stub,' or labeled with the builder's mitigation-system identifier, it is passive RRNC piping. If you have the original builder's foundation plans, RRNC-installed homes are typically called out in the foundation drawings. If you cannot find any vertical PVC running floor-to-roof, the home likely lacks RRNC piping and would require full retrofit if mitigation is needed.

Why is converting a passive RRNC stub to an active system cheaper than full retrofit?

All the expensive labor on a full ASD retrofit — coring the slab, running PVC through the home, sealing penetrations, routing past the roofline — is already complete on an RRNC home. The conversion is just adding a continuously-running radon fan to the existing pipe (typically in the attic), wiring it to a dedicated circuit, installing the U-tube manometer, labeling the system per EPA/IDPH requirements, and running post-mitigation verification testing. Total time on-site is 1-2 hours, versus 4-6 hours for full retrofit.

Does a West Des Moines newer home need testing if the builder said it has RRNC?

Yes. RRNC passive piping is designed to reduce sub-slab pressure but is not guaranteed to bring every home below 4 pCi/L without an active fan — that depends on soil permeability, foundation size, weather, and how well the slab was sealed during construction. EPA recommends testing every RRNC home post-occupancy to confirm passive performance is adequate. If results exceed 4 pCi/L, adding the fan is the inexpensive conversion described above; if below 4 pCi/L, no further action is needed beyond periodic retesting.

I'm building a custom home in West Des Moines. Should I require RRNC in my plans?

Yes. Adding RRNC passive piping during foundation construction costs $200-$500 in materials and labor — a tiny fraction of the $1,200-$2,500 it would cost to retrofit later. Even if post-occupancy testing shows passive RRNC achieves below 4 pCi/L without a fan, the piping is in place for future use if conditions change (e.g., basement finish, addition, or HVAC modification). EPA, IDPH, and the American Association of Radon Scientists and Technologists (AARST) all recommend RRNC as the standard for new construction in Zone 1 counties, which is every Iowa county.

Are there premium-tier ASD options for high-end West Des Moines homes?

Yes. Higher-end ASD installations include quieter fans (Festa AMG or Radonaway RP265 with low-decibel models), interior-routed PVC inside finished chases to avoid exterior pipe runs, digital pressure-monitoring with smartphone alerts, smart-fan controllers that adjust speed based on real-time radon readings, and architect-coordinated routing through unused conditioned chases. These add $400-$1,200 to the base ASD cost but produce a system that is essentially invisible in finished living space — a relevant consideration for a custom Jordan Creek or Glen Oaks home.
