If you’ve recently had radon testing in Zanesville, Ohio or Muskingum County, it’s important to know that radon levels are not constant. They can change over time. Here in Ohio, we can see rain, wind, and temperature swings all in the same week — sometimes the same day — and that can directly impact radon levels inside a home.

Rain: Saturated soil traps radon and pushes it toward the home.

Cold: Creates a “stack effect”, pulling radon inside.

Wind: Can increase pressure differences and radon entry.

Furnace: Running heat can increase negative pressure and draw in radon.

Different conditions = Different results.

The Environmental Protection Agency recommends action at 4.0 pCi/L or higher, and even 2.0–4.0 pCi/L may be worth addressing.

Learn how rain, cold, wind, and heating systems can affect radon levels in Ohio homes and when radon testing or mitigation may be needed.

The good news? Radon is fixable. I install radon mitigation systems in Muskingum County and surrounding areas that effectively reduce levels.
