Radon Mitigation Cost in North Dakota

North Dakota ranks #2 in the U.S. for radon risk. 100% of North Dakota counties are classified by the EPA as Zone 1 — the highest-risk category, with predicted average indoor radon levels above the EPA action level of 4 pCi/L. Here's what that means for mitigation cost.

North Dakota radon risk profile

North Dakota matches Iowa with 100% of its 53 counties in EPA Zone 1. The state's glacial-deposit geology and uranium-rich bedrock combine to produce some of the highest indoor radon levels in the country. Average indoor radon levels in North Dakota frequently exceed 4 pCi/L.

Typical mitigation cost

National typical range: $1,200-$2,500 installed for a standard active sub-slab depressurization (ASD) system in a single-family home. Multi-level or multi-zone homes can reach $3,000-$5,000. These figures are from aggregated contractor pricing surveys and are not specific to North Dakota.

We do not publish a North Dakota-specific average cost figure because no reliable state-level cost survey is publicly available. Get 2-3 quotes from EPA-listed certified mitigators in your county for accurate North Dakota pricing.

North Dakota-specific factors

North Dakota's cold-climate housing stock typically includes full basements, increasing exposure. The state has an active radon program and certified mitigation contractors throughout the state.

How to find a certified mitigator in North Dakota

The two main certifying bodies for radon mitigation are the National Radon Proficiency Program (NRPP) and the National Radon Safety Board (NRSB). Both maintain public contractor directories searchable by ZIP code. If you live in a state with a radon program (which North Dakota does), the state health department typically maintains a certified-contractor list as well — usually on the department's environmental health page.

Always retest after mitigation. A properly designed system should reduce levels to under 2 pCi/L; verify the result rather than trusting the contractor's word.
