About radon in Swisher
Linn County southern edge, on the Cedar Rapids commute route.
Eastern Iowa sits on glacial till over Devonian limestone bedrock. Average indoor radon levels in Johnson County run roughly 7-9 pCi/L, well above the EPA action level of 4.0. Most Swisher homes test in line with the broader Johnson County average — meaning a 7 in 10 chance your home will test above the EPA action level of 4.0 pCi/L.
What we do for Swisher homeowners
- Radon Mitigation System Installation — The standard fix for elevated radon. A sealed PVC pipe pulls radon gas from beneath your foundation slab and vents it safely above the roofline.
- Radon Testing — Short-term tests, long-term tests, real-estate-transaction tests, and continuous radon monitor placements. Results that hold up in inspection negotiations.
- Real Estate Radon Testing — Fast 48-hour radon testing for Iowa City real estate transactions. Results delivered directly to your agent or inspector.
- Sub-Slab Depressurization — The technical name for the most common radon mitigation method — a fan-driven negative-pressure system under your slab.
- Crawlspace Radon Mitigation — Crawlspaces require a different mitigation approach: a sealed vapor barrier (membrane) plus sub-membrane suction.
- Post-Mitigation Radon Testing — EPA recommends retesting every 2 years even after mitigation. We verify your system is still pulling levels under 4.0 pCi/L.
Real estate transactions in Swisher
Most Swisher home sales now include a radon test during the inspection period. If you're a seller, we can usually get a tester placed within 24 hours, results back within 5 business days, and — if levels are elevated — mitigation completed before closing. If you're a buyer who just received a high test result, call us. We work with agents and inspectors directly to get deals across the line.
