What is Radon and Why It Matters?
You May Have Radon
Without Knowing!
Can you smell dangerous gas in your home? What if a harmful gas was completely invisible? Could your home contain gas you cannot detect? How would you know if radon was present?
Long-term exposure to elevated radon levels is linked to serious health risks. The EPA estimates radon causes about 21,000 lung cancer deaths in the U.S. every year, making it the second leading cause of lung cancer after smoking. Testing is the only way to confirm whether your indoor air is affected, and it’s simple, quick, and gives clear answers so you can take the right steps if needed.

Why Radon Testing Matters
Radon is a naturally occurring radioactive gas created when uranium breaks down in soil and rock. It can enter buildings through cracks in foundations, floor gaps, and structural openings, allowing harmful levels to build up indoors without any visible warning signs.
- Radon is invisible and odourless
- Long-term exposure increases lung cancer risk

Frequently Asked Questions
Radon is a naturally occurring radioactive gas produced when uranium breaks down in soil and rock. It seeps into homes through foundation cracks, sump pits, and other openings, and because it has no smell or color, it can build up indoors without any warning signs.
The EPA ranks radon as the second leading cause of lung cancer in the United States, which is why testing matters even in a home that looks and feels fine.
Industry data for the Columbus Ohio area typically shows radon mitigation systems ranging from around $850 to $3,000, with many homes falling closer to the $1,000 to $1,200 range for a standard single-point system. Cost depends on your home's size, foundation type, and how many mitigation points a system needs.

Radon has no smell, color, or taste, so a home can have elevated levels with no visible sign at all. The only reliable way to know is a professional radon test, which measures the actual concentration in your home and compares it to the EPA's action level of 4 pCi/L.
Most radon mitigation systems use a vent pipe and fan to draw radon gas from beneath the foundation and release it safely outside, above the roofline and away from windows and living spaces. The system is designed around your home's foundation type and the areas where testing shows the highest concentrations.
Most residential radon mitigation systems are installed in about one day, depending on the size of the property and the complexity of the foundation. We walk you through the expected timeline during your free quote.
