Radon Testing in Chattanooga, TN

The Only Way to Know Is to Test

Radon is a naturally occurring radioactive gas that seeps up from the rock and soil beneath your home. You cannot see it, smell it, or taste it — and the ridge-and-valley geology under Chattanooga and Hamilton County produces some of the more elevated radon potential in Tennessee. The EPA identifies radon as the leading cause of lung cancer among non-smokers in the United States, and the surgeon general recommends that every home below the third floor be tested.

Two identical houses on the same street can test completely differently. Your neighbor's low reading tells you nothing about your basement. The only way to know your number is a properly conducted test.

How Our Radon Testing Works

1. Free phone consultation. Tell us about the home — basement, crawlspace, or slab; how it's occupied; whether a real estate transaction is involved. We'll recommend the right test type.
2. Professional test placement. A calibrated continuous radon monitor is placed at the lowest livable level of the home following EPA protocol — closed-house conditions, away from drafts, exterior walls, and humidity sources that skew results.
3. 48-hour measurement. The monitor records hourly readings, which also reveals tampering or unusual swings — important for real estate deals.
4. Clear written results. You get the average concentration in pCi/L, how it compares to the EPA action level of 4.0 pCi/L, and an honest recommendation: no action, re-test, or mitigate.

When Chattanooga Homeowners Test

Moving into or buying a home — especially with a basement or finished lower level (see real estate radon testing). Before finishing a basement — turning a basement into a bedroom, office, or den increases the hours your family spends at the home's highest-radon level; test first, because adding mitigation before drywall is cheaper and cleaner. After any foundation or HVAC work — new cracks, sump pits, or duct changes alter how radon moves through a house. Every 2–5 years as routine — radon levels drift as houses settle and soil conditions change.

DIY Kits vs. Professional Testing

Hardware-store charcoal kits can be a reasonable first screen, but they're single-point measurements, easily skewed by humidity and placement mistakes, and unusable in real estate transactions. Professional continuous monitoring gives you hour-by-hour data, tamper resistance, and a report a buyer, seller, or relocation company will accept. When the answer decides whether you spend $1,200 on a mitigation system, an accurate test is cheap.

Local, Honest, and Unhurried

We serve Chattanooga, Hixson, East Ridge, Red Bank, Signal Mountain, Soddy-Daisy, Ooltewah, Collegedale, Lookout Mountain, and nearby North Georgia. If your test comes back low, we'll tell you plainly and you won't hear a sales pitch. If it's elevated, you'll get a fixed, written mitigation quote — and the test fee is credited toward the system if we install it.
