Radon Testing & Mitigation
Two in five Minnesota homes are over the EPA action level. We measure it, and we fix it.
Radon is a colorless, odorless radioactive gas that rises out of the soil and collects in Minnesota basements — and Minnesota is one of the worst states in the country for it: the Department of Health estimates about 2 in 5 homes are above the 4.0 pCi/L level at which the EPA says act. You cannot smell it, and the only way to know your number is to measure it. We are MDH-licensed for both halves of the job: we test with calibrated continuous monitors and give you a written report, and if your level is high we install the mitigation system that brings it down — one licensed team, one point of contact, no chasing a second contractor while a sale is on the clock.

Is a test from the company that mitigates honest?
We measure and mitigate under the same MDH licence — but measurement is a licensed, regulated act, and the official MDH report is the report whether or not you have us mitigate. The number is the number.
Our Own Work





Our Radon Services
Real-estate transaction testing (48 hours)
A continuous radon monitor with hour-by-hour readings and tamper detection, run on a 48-hour turnaround to fit the inspection window, with the report delivered on your closing timeline. Minnesota sellers must disclose radon — a measured number beats a blank on the form, and if it comes back high we can quote the fix the same day so the deal keeps moving.
Home radon screening
A calibrated device placed at the lowest lived-in level under closed-house conditions, then a written report against the EPA 4.0 pCi/L action level with a plain reading of what it means and what to do next — whichever side of the line you land on.
Radon mitigation systems
When a confirmed level is at or above 4.0 pCi/L, an active soil-depressurization system vents the gas from under the slab to above the roofline before it enters the house. Designed for the specific foundation, routed to keep it tidy, and sized to hold your level well under the action level.
Post-mitigation verification
Every system we install is followed by a verification test that proves it is actually holding the level down — not just running. You get the before and after in writing, which is what a buyer, an agent or your own peace of mind needs.

Frequently Asked Questions
Why is radon a problem in Minnesota specifically?
Our geology and our winters. The glacial soils under most of Minnesota produce radon, and tightly sealed winter homes hold it in — the Minnesota Department of Health estimates about 2 in 5 homes statewide are above the 4.0 pCi/L action level, roughly three times the national rate. Every Minnesota county is considered high-risk. Radon is the leading cause of lung cancer in people who have never smoked.
How does the test work, and how long does it take?
A calibrated continuous monitor is placed at the lowest level of the home you regularly use, doors and windows kept closed apart from normal coming and going. A real-estate test typically runs 48 hours; a general home screening 2 to 7 days. You get a written report with your measured level, the hour-by-hour data, and what it means.
What happens if my result is high?
First we confirm it — the EPA recommends confirming before committing to a fix. If the level is at or above 4.0 pCi/L, the answer is a mitigation system, and because we are licensed for both we can quote and install it rather than handing you off. A properly designed active soil-depressurization system typically brings levels down sharply, and we verify the result with a follow-up test.
How does radon mitigation actually work?
An active soil-depressurization system draws the radon-laden air from under the foundation slab through a sealed pipe and a continuous fan, and vents it above the roofline where it disperses harmlessly before it can enter the living space. It runs quietly and continuously, uses very little electricity, and is the method the EPA recognizes as the most reliable fix for an elevated level.
Do I need this for a home sale?
Minnesota's Radon Awareness Act requires sellers to disclose what they know about radon, and buyers increasingly test during the inspection window. A transaction test runs on a continuous monitor with tamper indicators, to the protocol both sides of the sale can rely on. If it comes back high, having one licensed team that can also install the mitigation keeps the closing on schedule instead of stalling on a second contractor's calendar.
Are you licensed to do this?
Yes — MDH Radon Licence #RMIT 00117, for both measurement and mitigation. Minnesota law requires anyone measuring radon in a building they do not own, or installing a mitigation system, to be licensed by the Department of Health. Ask to see the licence; you should ask that of anyone doing this work in your home.
When is the best time to test?
Heating season — roughly October through April — gives the most representative worst-case reading, because the house is closed up and the stack effect that pulls soil gas indoors is strongest. A summer test is still valid; a winter test is the one that finds the peak.
How much does it cost?
We quote every job in writing before we book — testing depends on the test type and whether a real-estate timeline is involved, and mitigation is quoted after we see the foundation, because the system is designed to the house. Schedule a visit and you get the number in writing before any work starts.
