A home sale runs on a clock, and radon testing has to fit inside it. In Warren County — where indoor radon averages are among the highest in Kentucky — buyers’ inspectors flag radon constantly, and Kentucky’s Seller’s Disclosure form asks every seller directly: has this home been tested, and what were the results?
We run certified real estate radon tests on real estate timelines: monitor placed within days of your call, 48 hours of data, and a written report delivered to whoever your contract requires — usually the same day the monitor comes down.
The disclosure form comes first. Kentucky’s Seller’s Disclosure of Property Condition form — required in transactions involving licensed agents — asks whether the home has been tested for radon and requires known results and any installed mitigation system to be disclosed. An “unknown” answer isn’t reassurance; it just moves the question to the buyer’s side of the table.
The inspection window is the moment. Radon testing happens alongside the general inspection, inside the contingency period. That window is measured in days, which is why a test that takes 48 hours and a report that arrives the same day matter. Testing after closing means negotiating with nobody.
A high reading is a negotiation point, not a dealbreaker. Mitigation is a known, fixable line item. It’s routinely handled as a seller credit or a pre-closing installation — and a system that’s installed and verified turns a disclosure question into a selling point for the next buyer, too.
You’re about to make the largest purchase of your life over ground that channels radon better than almost anywhere in the state. A professional test during your inspection window costs a fraction of what it protects. If the number comes back high, you’ll know while you still have leverage: request mitigation, request a credit, or price it in. If it comes back low, you close with certainty instead of a question mark.
Testing before you list is the strongest move on the board. You control the timing, you’re never surprised mid-contract, and if the number is high you can fix it on your schedule instead of a buyer’s. An installed, verified mitigation system with a written post-mitigation test answers the disclosure form’s radon questions with documents instead of shrugs — and keeps your closing date exactly where you put it.
You already know the pattern: radon comes up in Warren County deals, and the difference between a deal that wobbles and a deal that closes is usually turnaround time. We work inside inspection windows every week — placement within days, results in 48 hours, reports formatted for the transaction file. When a client’s test comes back high, we quote mitigation in writing so the negotiation has a real number in it instead of a guess. If radon keeps showing up in your closings, we should know each other.
A mailed-in charcoal kit is fine for curiosity. It is not fine for a contract. Real estate transactions need results that stand up to scrutiny: continuous monitors sample hourly, log power interruptions and tampering, and produce a certified report that lenders, relocation companies, and the other side’s agent will accept. When a contract, lender, or relocation company requires a radon test, it must be a professional one — and closed-building conditions have to be followed, because monitors record the telltale swings when they aren’t.
Real estate radon testing is a small, flat line item — far less than the inspection itself — and we’ll quote it when you call, along with current scheduling. The standard rhythm: monitor placed within days of your call, 48 hours on site, certified report usually delivered the same day it comes down. If mitigation ends up in the negotiation, an itemized written quote follows fast enough to keep your contingency period intact. Details on how the measurement itself works are on our radon testing page, and the fix — if you need one — is on our radon mitigation systems page.
Who orders the radon test — buyer or seller?
Either. Buyers usually order it during the inspection window; sellers increasingly test before listing to control the timeline. Whoever orders it, the report belongs to the transaction — we deliver it wherever the contract requires.
What happens if the test comes back above 4.0 pCi/L?
The deal keeps moving. Mitigation is quoted in writing, and the parties negotiate who pays — commonly a seller credit or a pre-closing install. A properly designed system brings even severe readings below the EPA action level, verified with a retest.
Can we close before the mitigation system goes in?
That’s between the parties and the contract — credits at closing and post-closing installs happen all the time. What matters is that the number, the quote, and the plan are in writing before signatures.
Does an existing mitigation system mean we can skip testing?
No — it means the test should confirm the system works. Fans age and houses change. A current verification test is exactly what the disclosure form and a careful buyer want to see.
The seller’s disclosure says “unknown.” Is that a red flag?
It’s a blank, not a red flag — most Kentucky homes have simply never been tested. In this county, “unknown” is the strongest argument for testing during your window.
We’re on a 10-day inspection window. Is that enough?
Yes. Placement within days, 48 hours of monitoring, same-day reporting. Call on day one of the window, not day seven.
In Warren County, “has it been tested?” is a question every sale answers eventually. Answer it inside your window, with a number you can act on.
