About radon in Kalona
Washington County overflow. Mix of older Amish-built homes and newer subdivisions.
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 Kalona 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 Kalona 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 Kalona
Most Kalona 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.
