FAQ’s

FREQUENTLY ASKED QUESTIONS

  • Radon is a naturally occurring radioactive gas that comes from the breakdown of uranium in soil, rock, and water, and it can accumulate in homes and buildings, posing a health risk.

  • Radon is the second leading cause of lung cancer after smoking. Long-term exposure to high radon levels increases the risk of developing lung cancer.

  • Radon seeps into homes through cracks in the foundation, gaps around pipes, sump pits, and other openings in the structure.

  • The EPA recommends action if radon levels are at or above 4.0 pCi/L. However, no level of radon is completely safe, and lower levels may still pose a risk.

  • To test your home for radon, Apex Inspections offers radon measurement services through our team of state-certified specialists. If the initial test was conducted by another company, we can schedule the 48-hour post-mitigation test after the installation of the mitigation system to ensure effective results.

  • Radon mitigation is the process of reducing radon levels in a home or building using specialized ventilation systems.

  • A mitigation system typically uses a fan and vent pipes to draw radon from beneath the home and safely release it outside.

  • Most radon mitigation systems can be installed in 3–6 hours, depending on the home’s size and structure.

  • Costs vary based on the home’s layout, but typical radon mitigation systems done by 911 Radon Mitigation start around $1,500

  • The cost of radon mitigation depends on several factors, including the home's size, foundation type (slab, basement, or crawlspace), radon levels, and the complexity of the installation. Additional factors like the need for crawlspace sealing, multiple suction points, or electrical upgrades can also impact the overall price. A professional assessment will determine the best system for your home and provide an accurate estimate.

  • Yes, most systems reduce radon levels within 24 hours, but a post-mitigation test should be done after 48 hours to confirm effectiveness.

    Some scenarios that are more complicated in homes can require further mitigation. If radon levels remain high, adjustments may be needed, such as sealing additional entry points or upgrading the system.

  • The system is usually installed in the basement or crawl space, with a vent pipe running outside the home.

  • Most systems are very quiet, producing about the same noise level as a bathroom fan.

  • Minimal maintenance is needed, but the fan should be checked annually, and the system should be tested every two years.

  • Yes, all systems come with our standard 5 year warranty on the fan, which can be replaced at no cost withing the warranty period.

  • Yes, we include a post-mitigation radon test with every system installation.

10 SHOCKING Radon Facts

  1. Iowa Has the Highest Radon Levels in the U.S. – Over 70% of Iowa homes have radon levels above the EPA action level of 4.0 pCi/L.

  2. Radon Comes from Iowa’s Glacial Soil – The high radon levels in Iowa are due to the breakdown of uranium in the deep glacial deposits beneath the state.

  3. Radon is the Second Leading Cause of Lung Cancer – After smoking, radon exposure is the #2 cause of lung cancer, responsible for about 21,000 deaths per year in the U.S.

  4. There’s No Safe Level of Radon – Even radon levels below the EPA’s action level can still pose a health risk over time.

  5. Radon is Heavier Than Air – It collects in basements and crawlspaces, making lower levels of homes more dangerous.

  6. Radon is Odorless and Invisible – The only way to know if your home has high radon levels is through testing.

  7. New Homes Can Have High Radon, Too – Even brand-new homes in Iowa can have high radon levels, regardless of construction quality.

  8. Radon Levels Change Throughout the Year – Winter typically has the highest radon readings because homes are sealed up, trapping radon inside.

  9. Mitigation Systems Can Lower Radon by 99% – A properly installed radon mitigation system can dramatically reduce radon levels in a home.

  10. Iowa Requires Radon Testing in Schools – A new law requires all Iowa schools to test for radon by 2027, highlighting the state’s concern over exposure risks.
