A radon mitigation system creates negative pressure beneath your home's foundation, intercepting radon gas from Iowa's uranium-rich soil before it enters your living space. The 4-step infographic below shows exactly how the system protects your home 24/7.
Our partner network includes specialists certified for higher-complexity radon scenarios beyond standard single-family mitigation.
Apartment buildings, condos, and townhome developments require unit-by-unit testing and building-scale mitigation design. Partner contractors hold AARST-ANSI Multi-Family Measurement (MFM) and Multi-Family Mitigation (MFMT) certifications.
Federally-funded multi-family housing must meet HUD radon testing and mitigation standards. Our partner network handles compliance testing, mitigation design per HUD specifications, and required documentation for ongoing federal funding.
Radon Resistant New Construction (RRNC) builds passive mitigation into the foundation during construction — significantly cheaper than retrofitting later. Partner specialists work directly with Iowa builders on RRNC-spec foundations.
Pre-purchase testing, sell-side disclosure compliance, and closing-timeline mitigation — typical 7–14 day turnaround from test to verified install. Iowa real estate radon contingencies handled.
Iowa law requires schools to test all ground-contact occupied spaces every 5 years. Partner network provides compliant testing, mitigation design, and AARST-ANSI-standard installation for school facilities.
Brownfield sites and commercial buildings on contaminated land require sub-slab depressurization paired with vapor intrusion controls. Partner network includes specialists certified for combined radon + VOC mitigation.
