How to Prepare Your Home for an Accurate Radon Test

Radon is one of those things people don’t often think about until it becomes a problem. It’s a colorless, odorless gas that can sneak into your home from the ground beneath it, and it’s known to increase the risk of lung cancer. That’s why radon testing is something every homeowner should take seriously.

At Batten To Beam Inspections, based in Newtown Square, we’ve helped many homeowners get accurate radon measurements, and we’ve seen time and again that the key to a reliable test is simple preparation.

Why You Shouldn’t Skip Proper Preparation

It’s easy to think that a radon test is just set up and forget it, but the truth is, radon levels can shift depending on airflow, weather, and even how often doors and windows are opened. To get an honest reading, your home needs to stay in a particular state during the test.

What You Need to Do Before the Test

  • Keep Windows and Doors Closed
    At least 12 hours before the test starts, close all windows and exterior doors. This helps keep outside air from mixing in and changing the radon levels being measured.
  • Turn Off Your HVAC System (Unless Told Otherwise)
    Your heating and cooling system can influence air pressure and circulation in ways that affect the test. We’ll let you know if you should leave it off or keep it running, depending on the situation.
  • Minimize Water Usage
    Running a dishwasher, laundry, or taking long showers can cause pressure changes inside the home. Try to limit these activities during the test period.
  • Stay in the Home Normally
    You don’t need to vacate the home or do anything special during the test, except follow the instructions we provide.
  • Follow the Checklist Your Inspector Gives You
    We provide a simple radon test preparation checklist so you know exactly what to do before the inspection. It’s straightforward but important to follow closely.

What Happens After the Test?

Once the test is finished, we’ll review the results with you. If radon levels are above recommended limits, we’ll explain the next steps, like mitigation solutions that help lower radon to safe levels.

The Bottom Line

Getting your radon levels checked is about protecting your family’s health. It doesn’t have to be complicated, but skipping preparation can lead to inaccurate results.
