Radon

Radon gas is a silent threat—odorless, tasteless, and invisible—yet it can pose serious health risks when it accumulates in your home. If you’ve tested your home for radon and found elevated levels, you might be wondering how to reduce them quickly while you wait for a professional mitigation system to be installed.

The good news? There are some immediate actions you can take to lower radon levels fast. While these aren’t permanent solutions, they can help reduce your exposure in the short term. Let’s go over the best quick fixes to lower radon levels in your home today.

1. Increase Ventilation

Radon builds up in enclosed spaces with little airflow, so the first step is to bring in fresh air and improve circulation.

What You Can Do:

  • Open windows and doors, especially in the basement or lowest level of your home.
  • Use fans to create cross-ventilation, pulling fresh air in and pushing radon-contaminated air out.
  • If you have an HVAC system, set it to pull in outdoor air (if possible) rather than recirculating indoor air.

2. Seal Cracks and Gaps

  • Use caulk or expanding foam to seal cracks in basement floors and walls.
  • Check for gaps around pipes, sump pumps, and foundation walls-seal these as well.
  • Weatherstrip doors and windows to limit radon entry.

3. Run Your HVAC System or Air Purifier

  • Keep your HVAC fan running continuously to move air throughout the house.
  • Use an air purifier with an activated carbon filter, which can help trap radon decay products.
  • Consider installing an Energy Recovery Ventilator (ERV) or Heat Recovery Ventilator (HRV) to improve indoor air exchange.

4. Use a Sump Pump Cover

  • Install an airtight sump pump cover.
  • Use caulk or foam sealant to close any gaps around the cover.

5. Increase Basement or Crawl Space Ventilation

  • If you have a crawl space, open vents to allow air to flow freely.
  • Consider installing a small fan to exhaust air outside.
  • Keep dehumidifiers running to reduce moisture, which can trap radon gas.

6. Temporary Radon Fan or DIY Depressurization

  • Place a fan over an open sump pit or a small hole in the basement floor to draw radon out.
  • Vent the fan’s exhaust outside, at least 10 feet away from windows or doors.
