Radon Testing & Mitigation in Davenport, IA

Davenport radon projects typically invoice $150 to $2,500, with a measurement test running $150-$250 and a full ASD mitigation system on Scott County’s distinctive Mississippi-River-bluff limestone geology — among the highest radon-producing substrates in the Quad Cities region — running $1,200-$2,500. IARadonMitigation is an Iowa scheduled-testing and ASD-mitigation referral directory — call PHONE to be matched with an IDPH-licensed contractor serving Downtown, McClellan Heights, the Bettendorf border area, and the rest of Scott County across ZIPs 52801, 52802, 52803, 52804, and 52806.

How the referral works in Davenport

IARadonMitigation operates a scheduled pay-per-call referral directory. We do not perform testing or mitigation work and hold no IDPH credentials. Calls route to independent IDPH-licensed contractors regulated under Iowa Code Chapter 136B with NRPP or NRSB national credentialing verified. The contractor schedules an on-site visit and provides written documentation for the Iowa Association of Realtors disclosure file. You pay directly. Iowa is a one-party consent state under Iowa Code § 808B.2.

Typical cost in Davenport

A short-term radon test runs $150-$250. Long-term alpha-track is $50-$150. A standard Scott County ASD installation runs $1,200-$1,800; bluff-side homes with deep aggregate beds or multi-zone foundations push to $1,800-$2,500. Some Davenport homes near the river bluff start at very high pre-mitigation levels (15-25 pCi/L), and these are also the homes where ASD delivers the most dramatic reduction — typically to under 2 pCi/L. Post-mitigation verification is $150-$200. Cost data from HomeAdvisor, Angi, and AARST-NRPP Quad Cities surveys.

Real estate and Davenport homeowners

The Quad Cities real-estate market is unified across the Iowa-Illinois border, but radon disclosure follows the state where the property sits. For a Davenport listing, the Iowa Association of Realtors radon-rider standard applies. Mississippi River bluff geology means Scott County buyers tend to be more aware of radon risk than buyers in some other Iowa metros; pre-listing testing has become a normal part of the Davenport selling process. Standard Iowa homeowners insurance does not cover mitigation.

How to choose a radon contractor in Davenport

Verify IDPH license status at idph.iowa.gov
Confirm NRPP or NRSB credentialing
Confirm general liability and workers’ comp
Get the proposal in writing with suction point, pipe routing, fan model, verification schedule, warranty
For bluff-side homes with very high baseline levels, ask whether the contractor has experience reducing radon from 15-25 pCi/L to under 2 — this typically requires careful suction-point selection and sometimes multiple suction points
Save installation photos, system label, manometer reading, and post-mitigation report

Frequently asked questions

Why does Davenport sometimes test higher than other Iowa cities?

Davenport sits on the Mississippi River bluff, where limestone-and-shale bedrock is closer to the surface than in glacial-till parts of central Iowa, and where the bluff face exposes uranium-decay sources directly to home foundations. Scott County is firmly in EPA Radon Zone 1 like all 99 Iowa counties, but bluff-side neighborhoods in Davenport and Bettendorf frequently produce pre-mitigation reads in the 10-25 pCi/L range — well above the statewide median. The Iowa Geological Survey at the University of Iowa publishes substrate maps that explain the elevated risk along the river-bluff corridor.

I tested at 15 pCi/L. Is mitigation in Davenport still going to bring me below 4?

Yes. An IDPH-licensed mitigation contractor designs the ASD system to handle the specific pre-mitigation level, and for very high readings (10-25 pCi/L) the contractor may use a larger-capacity fan, multiple suction points, or both. Post-mitigation reads in the 0.5-2 pCi/L range are routine even on homes that started at 20+. Ask the contractor about their experience with high-baseline Quad Cities homes and request references for similar pre-mitigation levels.

Does Davenport have any local rules about radon beyond Iowa Code Chapter 136B?

No municipal Davenport radon ordinance currently goes beyond the state-level IDPH program. Scott County health department aligns with IDPH guidance on testing and mitigation standards. The Quad Cities International Code Council adoption of building codes does include RRNC-related provisions for new construction in some Bettendorf and Davenport subdivisions, but enforcement varies; ask the builder whether passive sub-slab depressurization piping was installed during the foundation pour.

Can the same Davenport contractor both test and mitigate, or does that create a conflict of interest?

Iowa Code Chapter 136B and EPA guidance both recognize the potential conflict and address it through licensure and documentation: an IDPH-licensed measurement specialist who also holds a mitigation license can perform both, but the post-mitigation verification test is the documented step that proves the system works. For full transparency, some Davenport homeowners prefer to hire one IDPH-licensed measurement specialist for the initial and post-mitigation tests, and a separate IDPH-licensed mitigation contractor for the installation. Both arrangements are EPA-compliant; ask the contractor which model they prefer.

How long does an ASD system last in a Davenport home?

The PVC piping and foundation seals are essentially permanent (decades), and the radon fan typically lasts 10-15 years before efficiency declines and replacement is recommended. A Festa or Radonaway replacement fan costs $300-$600 installed. The U-tube manometer should be checked monthly by the homeowner — if the colored fluid is at equal levels in both legs, the fan has stopped pulling and needs service or replacement. EPA recommends re-testing every 2 years even on a working system to confirm continued mitigation, and after any major foundation work, basement renovation, or HVAC change.
