Real Estate Radon Testing in Chattanooga

Radon and the Home Sale

Radon testing has become a standard line item in East Tennessee real estate transactions — and for good reason: our geology puts a meaningful share of Hamilton County homes over the EPA action level. For buyers, a $150-range test protects you from inheriting a $1,500 problem, and an elevated result is a routine negotiation item, not a deal-killer. For sellers, testing before listing means no surprises during the option period — and if mitigation is needed, you control the contractor and cost instead of crediting the buyer's inflated estimate at the closing table.

Built for Transaction Timelines

1. Fast scheduling. Inspection windows in this market are often 7–10 days. We place monitors within a day or two of your call, including occupied and vacant homes, with listing-agent coordination handled for you.
2. Tamper-resistant continuous monitoring. Real estate tests are exactly where measurement games happen — windows opened, monitors moved, fans aimed. Our continuous monitors log hourly readings, movement, and power interruptions, so both sides can trust the number.
3. 48-hour protocol test, immediate reporting. Results are delivered the same day the monitor is picked up, in a format agents and relocation companies accept, with the hourly graph included.

If the Result Comes Back High

Nobody needs to panic and nobody needs to walk. Mitigation is a one-day, permanently effective fix that typically costs $900–$2,500 — small in the context of a home purchase, and usually negotiated as a seller credit or pre-closing repair. We provide fixed written mitigation quotes that can go straight into the repair addendum, and post-installation verification testing that satisfies both parties. See how mitigation works.

Common Transaction Questions

Does Tennessee require radon testing to sell a home? No — but buyers increasingly require it, and sellers' disclosure obligations apply to known results, which is another reason to test on your own timeline. Can we use the seller's old test? Levels change; most buyers' agents want a current test under closed-house conditions. Vacant house? Fine — closed-house conditions are actually easier to maintain. New construction? Test anyway; new slabs crack, and passive rough-ins often need a fan added to work.
