Failed Radon Test During a Home Sale: What Happens and Who Pays

Who pays for radon mitigation, buyer or seller? Payment depends on the purchase agreement and any negotiated amendment. A failed radon test does not automatically make either party responsible for the bill. Buyers and sellers can discuss installation, a credit or another agreed response with their agents. Put the payment, scope and follow-up testing terms in writing.

What happens if a house fails the radon test?

A failed radon test usually means a result exceeds the action level used for the transaction. Start by reviewing the actual concentration, test location, dates and any report notes. The word failed is shorthand; the complete report is what the parties and contractor need.

Send the report to your agent while the inspection-response period is open. Ask the measurement professional to explain any limitation or interrupted test condition. If mitigation is proposed, obtain a scope for the property rather than negotiating from a generic internet price.

  • Keep the original report and attachments.
  • Record the response deadline from the contract.
  • Request a written mitigation scope when appropriate.

Who pays for radon mitigation, the buyer or the seller?

Payment responsibility comes from the parties' agreement, not from a universal rule that sellers always pay. Possible proposals include seller-arranged work, an agreed credit or a buyer-arranged installation. These are negotiation options, and the contract and financing terms determine which can be used.

Discuss more than the total amount. Someone must select the contractor, approve the route, authorize access and arrange verification. Have your agent or attorney document the accepted terms so a verbal discussion does not leave the most important details unresolved.

  • Name the party ordering the installation.
  • State who pays for the work and any follow-up test.
  • Define the documentation to be supplied.
  • Ask the lender whether a proposed credit is permitted.

Can mitigation be finished before closing?

Mitigation can be completed before some closings, but the schedule must be confirmed for the specific house and scope. Do not rely on an assumed installation date. Access, contractor availability and the follow-up measurement all need a place on the calendar.

Air Sense Environmental can review the property details and discuss scheduling at 314-664-9807. Send the report and both the inspection deadline and closing date. An installation date and a final report date are different milestones; your agreement should say which one matters.

If the available schedule does not fit, discuss the options with the people handling the sale before signing an amendment. This page does not promise payment at closing, escrow arrangements or a particular completion window.

  • Confirm equipment access with the owner.
  • Allow for the required testing conditions after work.
  • Identify who receives the completion records.

What is a radon contingency?

A radon contingency is contract language that addresses testing and what the parties may do after the result. Its effect depends on the wording, deadlines and applicable transaction rules. A general online description cannot establish a right to cancel, demand repairs or receive a credit.

Ask your agent or attorney to explain the actual clause before its deadline passes. Have them distinguish the deadline for ordering a test from the deadline for notifying the seller or reaching an agreement. Keep the technical report separate from the legal interpretation of the contract.

Questions before you book

Who pays for the original radon test?

Confirm that in the inspection agreement or purchase documents. The party scheduling the appointment should establish billing before the test begins.

Should a seller simply open windows to lower the result?

No. Follow the test instructions. Changing the required conditions can invalidate a measurement and delay a useful decision.

What documents are useful after mitigation?

Request the invoice or completion record, system instructions, relevant warranty documents and the follow-up radon report agreed in the scope.
