A house can look flawless on the surface, yet hide dangers you can’t see or smell. Radon is one of the biggest of those risks. This radioactive gas seeps into homes through the ground and, over time, can cause serious health problems, including lung cancer.
The only way to know if a home is safe is through proper testing. In this blog, we’ll explain why radon testing should be a non-negotiable step in every home purchase.
What is Radon and Why Should You Be Concerned
A colorless, radioactive gas with no odor, radon seeps from the ground. It gets access to houses by cracks in foundations, floors, or even water systems. You cannot see or smell it; unless you test it, it slips in unnoticed. Here’s the scary truth:
- According to the EPA, radon is the second most common cause of lung cancer in the U.S. after smoking.
- The agency also approximates that 1 in 15 homes contains higher levels of radon, and over 21,000 Americans succumb to radon-related lung cancer annually.
- According to a recent survey, 75% of Americans have never tested their homes for radon, despite their easy availability and affordability.
- If you’re buying a home without radon testing before, you’re rolling the dice with your and your family’s health.
True Story: A Secret Threat
Kerri Robbins of Lehi, Utah, lived for many years unaware that her house was contaminated with 31.3 pCi/L of radon, far exceeding the EPA action level. Unfortunately, she got lung cancer that spread to her brain. She spreads awareness now so others can stay safe.
A homeowner was inspired by her story, had a mitigation system tested, and discovered a 19.7 pCi/L radon level. She installed the mitigation system and swears that Kerri saved her life and that of her children.
That’s the power of radon testing: it saves lives.
What Happens When You Skip It
This is an actual case: A family had built their dream house and moved in. A year later, they discovered a dangerous radon level in their basement. Their joy turned into horror. Radon cannot be detected on its own. Testing is crucial here.
When you do not have a radon test before purchasing a house, you are in the dark about the risks. And costs? Mitigation systems are not prohibitively expensive, but finding radon in the nick of time can cost thousands of dollars and sabotage your peace of mind.
When to Test (Why It Should Figure in Every Home Purchase)
This is why it is important to test before you wrap up the sale:
- Real estate experts and the EPA advise including it in the process of buying and selling a property. It is economical, simple, and part of due diligence.
- When levels exceed 4 pCi/L, the EPA recommends action. Mitigation, however, must be taken into consideration, even at levels of 2-4 pCi/L.
- Testing provides peace of mind and a sound footing when negotiating, whether to seek mitigation or to walk away.
Reddit Reality Check
On Reddit, one of the buyers shared that his agent said that he did not need to test for radon. Months later, their concentrations had been eight times greater than what they were supposed to be, and they immediately installed a mitigation system.
A second prospective buyer explained how radon levels could vary erratically and how a 48-hour reading in a low spike could be misleading. Short-term tests are frequently used in the real estate world due to time constraints; however, this tool can be inaccurate.
What’s the Right Approach
Here’s what makes radon testing before buying a house smart:
- It is cheaper than closing expenses.
- Short-term tests provide a snapshot, but long-term or professional tests offer more accuracy.
- A mitigation system (such as a fan and a vent pipe) can minimize radon by up to 99% and often does not involve significant renovations.
- Testing helps protect your investment, as well as your health.
Summary Checklist

| Use at least a short‑term test, or better, a professional one | Accuracy matters, especially when buying |
| Review results before closing | Negotiate mitigation or adjust your offer if needed |
| Install a radon reduction system if needed | It’s proven, affordable, and effective |
