Radon for Real Estate Transactions in Central Pennsylvania
Radon is a routine part of many real estate transactions across Dauphin, Cumberland, Lancaster, and York counties, and it usually arrives with a deadline.

Send your settlement date with the form and we route your request to a contractor who can move quickly. Quotes are free and come with no obligation.
What Pennsylvania law asks of sellers
Pennsylvania does not force a homeowner to test before selling, but it does require honesty about what you already know. Under the Pennsylvania Real Estate Seller Disclosure Law (68 Pa.C.S. Chapter 73), a seller must disclose radon test results and known hazards on the standard Seller's Property Disclosure Statement. Because this region sits in EPA Radon Zone 1, buyers here often request a radon test during the inspection period regardless of whether the seller has tested.
Buyer and seller scenarios
If you are selling
A recent, clean radon reading is one less thing for a buyer to worry about. If a test comes back high, mitigating before you list, or being ready to negotiate it, keeps the deal moving. Pennsylvania law also requires you to disclose radon results you already know about.
If you are buying
A radon test during your inspection window tells you what you are walking into. If the reading is elevated, you can ask the seller to mitigate as a condition of the sale, then confirm the fix with a retest before you close.
Either way, the process starts with a measurement. See radon testing for how readings are taken, and radon mitigation for how an elevated result is fixed.
Working against a settlement date
A real estate radon timeline is short by design. A certified tester places a continuous radon monitor under closed-building conditions so the reading is defensible, and if mitigation is needed, a system can often be installed in a single visit and retested before closing. The EPA publishes a home buyer's and seller's guide to radon that walks through the same steps.
What moves the cost in a transaction
- Whether you need testing only, or testing plus a mitigation system
- How tight the settlement timeline is and whether a rush placement is needed
- The foundation type and size of the home being mitigated
- Whether a post-mitigation retest is required before closing
The Pennsylvania DEP's radon fact sheet puts most mitigation systems at about $800 to $1,200. The contractor you are matched with gives both sides a free written quote to negotiate from.
Failed the radon test days before closing?
This is fixable on your timeline. Many single-family systems are installed in one visit, and a post-installation retest can be read within days, so a reading that arrives late in the inspection window does not have to move your settlement date. Having three things ready speeds up the quote: the number on the radon report, your settlement date, and the foundation type (basement, crawlspace, or slab).
Send those with the form and your request is routed to an independent, licensed contractor certified by the Pennsylvania DEP who works on transaction deadlines in Dauphin, Cumberland, Lancaster, and York counties. Who pays for the system stays a negotiation between buyer and seller; the written quote gives both sides the number to negotiate with.
Verify Your Contractor's PA DEP Certification
Under Pennsylvania's Radon Certification Act of 1987, anyone who performs radon testing, mitigation, or laboratory analysis for hire must be certified by the Department of Environmental Protection. Certification is the state's baseline for who may do this work, so confirm it yourself before you sign anything. Every contractor you are matched with through this site is asked to hold current DEP certification, and you can check any name against the official state records below.
Three questions to ask before you hire
- May I see your current DEP certification number?
- Is the person doing the work the certified individual?
- Will you retest after installation to confirm the reading dropped?

Real Estate Radon Questions
Is radon testing required to sell a home in Pennsylvania?
Pennsylvania does not require you to test a home before selling it. It does require disclosure: under the Pennsylvania Real Estate Seller Disclosure Law, a seller must disclose radon test results and known hazards on the Seller's Property Disclosure Statement. In practice, buyers frequently request a radon test during the inspection period even when it is not mandated.
Who pays for radon mitigation in a home sale?
There is no fixed rule. Payment for a mitigation system is a negotiation between buyer and seller, and it often depends on the reading and the local market. The contractor you are matched with provides a free written quote, which gives both sides a real number to work from during negotiations.
How fast can testing and mitigation happen for a closing?
A short-term radon test can be read in a matter of days, and many single-family mitigation systems are installed in one visit. Because transactions run on a deadline, tell us your settlement date and we connect you with a contractor who works on that timeline.
What radon level triggers action in a transaction?
The EPA action level of 4 picocuries per liter (pCi/L) is the standard benchmark used in real estate. At or above that reading, buyers commonly ask for a mitigation system. The EPA also suggests considering action between 2 and 4 pCi/L.
The radon test came back high days before closing. Can it still be fixed in time?
Often, yes. Many single-family mitigation systems are installed in one visit, and a post-installation retest can be read within days, so even a tight settlement window can work. Send your settlement date and the test reading with your request and we route it to a DEP-certified contractor who works on transaction timelines.
Should the home be retested after mitigation before closing?
Yes. A retest after the system has run confirms the level dropped below the action level, and it gives the buyer documented proof the fix worked. Ask that a post-installation retest be part of the scope, and verify the contractor's DEP certification in the state directory.
