Radon testing in Detroit: what to expect

Radon testing in Detroit is the only way to know whether this odorless, colorless gas is building up in your basement or lowest living level. EGLE, which runs the Michigan Indoor Radon Program, expects about one in four Michigan homes to exceed the federal action level of 4 picocuries per liter (pCi/L), and elevated results turn up across the state.

In real estate deals, home inspectors in Wayne, Oakland and Macomb counties usually place a continuous radon monitor for a short-term test during the inspection window. The test runs under closed-house conditions, with windows and exterior doors kept shut, and the monitor records hourly readings so tampering or open windows show up in the data.

EGLE recommends testing every two years because houses settle, new foundation cracks form and radon levels change, and it is smart to retest after major renovations. If the result is at or above the action level, compare radon mitigation contractors or bundle the test with a buyer home inspection from local home inspectors in Detroit.

What a proper job includes

  • Placement in the lowest level used or likely to be used as living space
  • Closed-house instructions for the seller or occupants
  • A calibrated continuous radon monitor or approved test device
  • Hourly or interval readings with an average result in pCi/L
  • Tamper and movement detection on professional monitors
  • A written report explaining the result against the EPA action level

What drives the price

  • Continuous monitor versus lab-analyzed test kit
  • Bundled with a home inspection or booked on its own
  • Number of test locations in larger or multi-unit buildings
  • Rush results for a short contingency period
  • Travel distance and pickup trips
  • Retests after mitigation

Licensing and standards in Michigan

According to EGLE, radon testers are not licensed or regulated in Michigan. EGLE recommends choosing a tester certified by the National Radon Proficiency Program (NRPP) or the National Radon Safety Board (NRSB). Ask for the certification number and confirm it with the certifying body.

For a home sale, agree in writing who orders the test, where the device goes and how results are shared. EGLE also publishes guidance for buyers, sellers and renters.

How to compare quotes

  1. Ask whether the tester holds NRPP or NRSB certification.
  2. Confirm the device type and when it was last calibrated.
  3. Ask how closed-house conditions will be communicated to the seller.
  4. Confirm how fast results arrive relative to your contingency deadline.
  5. Ask whether the report includes the full data log, not just the average.
