Negotiating radon repairs
Radon negotiations go badly when one side believes a legal requirement exists that does not, and well when both sides are arguing about money with a real quote on the table.
This page describes what each party actually holds, and the language that keeps the agreement from unravelling later.
What each side actually holds
The buyer holds contractual inspection rights — whatever the contract grants, which frequently includes the ability to request repairs, renegotiate, or terminate within a window. That is leverage, and it is contractual rather than statutory.
The seller holds the property, a disclosure obligation about what they know, and no legal obligation to install anything at any concentration in the states served here. Sellers who understand that negotiate from a much steadier position than sellers who believe 4 pCi/L is a repair mandate.
Anchor on a written quote, always
The single most useful move available to either party is producing a written quote from a credentialed mitigation contractor. It converts an open-ended argument into a defined number, and whoever brings it generally sets the frame.
Sellers should get one preemptively when a result comes back high. Buyers should get one rather than accepting a seller's figure. Two quotes are better than one, because a range is harder to dismiss than a single data point.
The three landing zones
Almost every radon negotiation resolves into one of three shapes, and it is worth knowing which one you are aiming for before you make the first ask.
- Seller completes the mitigation before closing and provides the post-mitigation verification result. Cleanest for the buyer; most coordination for the seller.
- Seller credits the buyer an amount sized to a written quote, with the quote attached to the addendum. Buyer controls contractor and design.
- Price adjustment with the result disclosed and no repair obligation. Simplest, and common where the reading is modest or the buyer wants control without a paper trail on repairs.
Addendum language that prevents later disputes
Whatever the shape, four elements belong in writing. The credential required of whoever does the work. The requirement of a post-mitigation verification test after at least twenty-four hours of runtime, on the lowest lived-in level. Delivery of that result to the buyer. And a stated remedy if the verification comes back above the agreed threshold.
That last element is the one everyone forgets, and it is the one that matters when a system underperforms. Naming the remedy in advance — an additional suction point, further sealing, or a defined credit — turns a potential dispute into a procedure.
Negotiating radon repairs: common questions
What is a reasonable radon credit?
One sized to an actual written quote for the specific house, not a regional average. Costs vary substantially with foundation type, suction point count, sealing scope, and routing difficulty, and a credit built on an average is a credit that is wrong for most houses. Attach the quote to the addendum and the number defends itself.
The seller refuses to do anything. What are my options?
Whatever your contract gives you — commonly renegotiating price, terminating within the inspection contingency, or proceeding and handling mitigation yourself after closing. Radon is not usually a reason to lose a house you want, since the remedy is well-defined and the cost is knowable. Get a written quote so you know exactly what proceeding costs you.
Can the buyer require a specific contractor?
Only if the seller agrees to it, since the seller is the one contracting for work on a property they still own. What buyers can reasonably insist on are the standards: the state-required mitigation credential, a written scope, and a delivered verification result. Those achieve the same protection without dictating a vendor.
