Why It Matters

Radon is the leading cause of lung cancer in non-smokers

  • The EPA and Surgeon General estimate radon causes about 21,000 lung-cancer deaths a year in the U.S.
  • You can't see, smell, or taste it – the only way to know is to test.
  • Levels run higher in winter, when homes are sealed up – peak testing season here is January.
  • If your test is 4.0 pCi/L or above, the EPA recommends a mitigation system.

How radon enters your home
Rn ↑ soil gas

Radon rises from the soil and is pulled in through cracks, sump pits, and the slab. A mitigation system captures it below the foundation and vents it safely above the roof.

Questions

Radon Mitigation FAQ

How much does radon mitigation cost in Sioux Falls?

Most residential radon mitigation systems fall in a typical range depending on your home's size, foundation, and layout. We give free, upfront quotes so you'll know the exact cost before any work begins – no surprises.

Is radon really a problem in South Dakota?

Yes. South Dakota ranks among the highest-radon states in the country, and much of the Sioux Falls area sits in an EPA high-radon zone. A large share of homes here test above the action level, which is why testing is so important.

How does a radon mitigation system work?

The most common and effective method is sub-slab depressurization: we install a fan and vent pipe that pull radon from beneath your foundation and safely release it above the roofline, before it ever enters your living space. A good system reduces radon by up to ~99%.

How long does installation take?

Most homes are completed in a single visit – typically just a few hours. We then re-test to confirm your levels are below the EPA's 4.0 pCi/L action level.
