Des Moines Real Estate Radon FAQ

Closing-Timeline Questions Des Moines Buyers + Agents Ask

Frequently Asked Questions

Home inspection radon test failed on my Des Moines purchase — what now?
If your buyer's inspection radon test returned at or above 4.0 pCi/L, you have a routine Des Moines transaction decision. The most common path: seller-paid mitigation completed before closing. Quote arrives within 2 hours of forwarding us the inspection report. Install in 4-8 hours of on-site work. Post-mitigation verification within 48-96 hours. Closing documentation package within 11 days. Most Des Moines radon contingencies fit comfortably inside this window.
How quickly can radon mitigation happen before closing in Des Moines?
Des Moines real-estate-transaction radon mitigation timeline runs Day 1-11: quote (Day 1) → buyer/seller agreement (Day 1-3) → priority install (Day 3-7) → 48-96 hour post-mitigation verification (Day 8-10) → lender-acceptable documentation package (Day 11). Real-estate-transaction jobs jump our standard queue; no rush premium.
Who typically pays for radon mitigation in a Des Moines home sale?
Roughly 60% of Des Moines real-estate-transaction radon mitigations are seller-paid (seller fixes before close), 30% are negotiated as a closing credit (buyer takes cash at close), 10% are buyer-paid. The Iowa Real Estate Purchase Agreement does not mandate which party pays — your real estate agent negotiates with the other side. The seller-paid + repair-before-close path is preferred by FHA, USDA, and VA underwriters.
What does radon mitigation cost in Des Moines, IA?
Des Moines single-family radon mitigation typically runs $800-$2500. Standard active sub-slab depressurization (ASD) is the most common system type (~85% of Des Moines installs). We do NOT charge a rush premium for closing-timeline work; real-estate-transaction jobs price at the same range as standard installs.
Does Des Moines have higher-than-average radon levels?
Des Moines (Polk County) averages 9.2 pCi/L indoor radon — that's 2.3x the EPA action level of 4 pCi/L. Approximately 71% of Des Moines homes test elevated. Cold winters drive negative pressure in basements (stack effect), pulling radon-laden soil gas indoors. Iowa winter radon levels typically test 30-50% higher than summer measurements. This means a failed-inspection radon test on a Des Moines listing is not unusual — it should be expected on a meaningful share of transactions.
Will an FHA / VA / USDA lender accept Des Moines radon mitigation documentation?
Yes. Our standard real-estate-transaction documentation package includes (1) the original inspection radon result, (2) the partner contractor's NRPP + IDPH certifications, (3) the post-mitigation verification test result confirming the home is below 4 pCi/L, and (4) install warranty (5-year fan, lifetime piping). This package is accepted by FHA, USDA, VA, and all major conventional lenders without further documentation requests.
Can Des Moines radon mitigation happen during the standard 10-day inspection contingency window?
Yes — the 7-14 day mitigation workflow fits inside most standard Des Moines 10-14 day inspection contingency windows. If the contingency was written tighter (5-7 days), a contingency-extension agreement between buyer and seller is typically the cleanest path; your real estate agent can advise on standard Iowa extension language.
Should Des Moines sellers pre-test for radon before listing?
Strongly recommended — especially in Polk County where county average is 9.2 pCi/L. Pre-listing radon testing lets Des Moines sellers (1) surface elevated readings before going under contract, (2) mitigate proactively at standard pricing instead of under buyer-side closing pressure, (3) market the home with a verified-mitigated radon result as a transaction advantage. Listings with documented pre-mitigation typically close faster and at full price.
