Radon is a colorless, odorless radioactive gas — and the leading cause of lung cancer in non-smokers. About 2 in 5 Minnesota homes test above the EPA action level of 4.0 pCi/L. The state of Minnesota recommends testing every home, every two years, and every real estate transaction.
We use professional continuous radon monitors (CRMs) that log hourly readings for 48 hours — far more accurate than charcoal canisters. Results are delivered the same day the test ends.
If your test comes back high, mitigation is straightforward and effective — typically a sub-slab depressurization system that drops levels below 2.0 pCi/L.

Common questions about radon testing
Is radon testing worth the cost?
For most Mankato-area buyers, yes. The cost is small relative to what a missed issue could cost after closing.
How long does radon testing take?
Varies by scope — most service-specific add-ons take 20–60 minutes on top of the home inspection. We bundle them into one visit.
Do you bundle radon testing with a home inspection?
Yes — bundling saves $50–$100 vs. booking separately and means one report and one bill.
Where do you offer this service?
Mankato and a 50+ mile radius across Southern Minnesota — see our service area page for a full list of cities.
How fast do I get the report?
Same day for most inspections. Always within 24 hours.
