Radon Testing
EPA-protocol 48-hour radon test. Required-knowledge in our Zone 1 service area.
Radon is a naturally-occurring radioactive gas that comes from soil and accumulates in homes. It is the second-leading cause of lung cancer in the US. Our entire service area is in EPA Radon Zone 1 — the highest-risk category — meaning every home should be tested.
Why this matters
You cannot see, smell, or taste radon. The only way to know if a home has elevated radon is to test. EPA recommends mitigation when levels exceed 4.0 pCi/L. Mitigation systems cost $1,500-$3,000 — but only if you know to ask.
What's covered
- ✓48-hour EPA-protocol short-term test
- ✓Calibrated continuous radon monitor (not a charcoal canister)
- ✓Detailed reading-by-reading report
- ✓Recommendations if levels exceed action threshold
- ✓Reference to licensed radon mitigation contractors if needed
Southern Minnesota considerations
All of Martin, Faribault, Blue Earth, Nobles, Cottonwood, Jackson, Watonwan, and surrounding counties are EPA Radon Zone 1 — the highest-risk zone. Northern Iowa counties are similarly high-risk. Testing is essentially mandatory due-diligence.

Common questions
How long does radon testing take?
48 hours minimum, per EPA protocol. We deploy the monitor at inspection and pick it up 48 hours later. Results in the next 24 hours.
What if the level is high?
Mitigation systems work — they typically reduce radon by 90% or more. Cost is $1,500-$3,000 installed. Sellers commonly cover this in negotiation.
Are charcoal canisters as accurate as continuous monitors?
No. Charcoal canisters give a single average reading. Continuous monitors track radon hour-by-hour and detect tampering. We use continuous monitors only.
