Need to Keep the Closing Moving?
When a buyer's radon test comes back high, call early. Bill can look at the home, give you a real quote, and help you understand the schedule so radon does not become a last-minute closing problem.
When a buyer's inspection finds elevated radon, the listing side needs a calm plan. The sooner someone calls, the more options the seller usually has.
Bill's advice to sellers is simple: do not let radon sit on the repair list while everyone works through credits, repairs, and closing details. Have Bill look at the home, get a real plan, and decide whether to schedule the install. Once the system is installed and the paperwork is ready, radon is one less issue sitting between contract and closing.
Some buyers prefer a credit. Some buyers want the system installed before closing. Calling early gives the seller flexibility either way. Waiting until the last minute can turn a simple fix into a scheduling problem.
That does not mean rushing a sloppy install. It means calling early, letting Bill look at the home, scheduling around the closing date, and finishing the job cleanly so the file has what it needs.
Sellers are often buying their next home at the same time. While we fix the house under contract, Bill likes to ask about the new place. People feel better talking about where they are going. It is also smart: the next home should be tested too, and if mitigation comes up there, we can put a quote in their hands for that conversation as well.
What Bill usually recommends
Do the work as soon as you can
Once elevated radon is on the report, it sits there until someone handles it. Calling early gives the seller the most flexibility. If the seller decides to install the system, the work can be completed, documented, and taken off the repair list before it becomes a late-stage closing problem.
Get a real quote and understand the schedule
Bill can look at the home, explain the mitigation plan, and tell you what is realistic for the calendar. Calling early gives you more options and keeps the closing conversation simpler.
Early action gives the seller more flexibility
Some buyers prefer a seller credit or concession. Some buyers want the system installed before closing. Calling early keeps both paths open instead of boxing the seller into a last-minute scramble.
Installing and documenting the system removes radon as an open repair item
When the work is done and the paperwork is ready, radon is no longer sitting on the table as an unresolved negotiation problem. The file has a finished system and documentation.
While we are at it, talk about the next house
Sellers are often buying something too. Bill often asks about the new place, reminds them to get it tested, and can quote that home if mitigation comes up there as well.
A finished system helps the next conversation too
If this deal does not close, a documented mitigation system can still help with the next buyer. A future buyer may still test the home, but they are no longer walking into an untouched radon issue. They can see that the home has already been addressed, the system is in place, and the paperwork is ready.
A simple script for listing agents
"Elevated radon came up on the inspection. It is common, and it is fixable. The cleanest path is usually to call Bill early, get a clear plan, and decide whether to put the system on the calendar. If the seller chooses to install, the work gets documented and radon comes off the open repair list instead of turning into a last-minute closing problem."
Not legal or contract advice. Listing agents and sellers should talk with their agent or attorney and use their own transaction process when needed.

Seller & Listing Agent Radon FAQs
Practical answers when a high radon test shows up before closing. Not legal advice. Talk with your agent or attorney about the contract side.
What should a seller do if the buyer’s radon test comes back high?
Call early. Bill can look at the home, give a real quote, and help you understand the schedule. If you decide to install, the radon issue gets handled, documented, and removed as an open repair item instead of sitting as a negotiation problem near closing. Talk with your agent or attorney about the contract side.
What do most realtors recommend when a seller’s home tests high?
Most agents want a calm plan: state-licensed mitigation, clear timing, and paperwork that holds up in the file. Some deals use a seller-paid install and some use a credit. The right path depends on the contract and the parties. We are not giving legal advice. We give a realistic schedule, a clean system, and documentation agents can use.
Can radon delay a closing, and how fast can you install?
It can if nobody calls until the last minute. Most of our installs are one visit once the plan is set. Tell us the closing date early. We will say what is realistic. Documentation is ready for the file when the job is complete.
Need Radon Handled Before Closing?
Call Bill with the address, the result if you have it, and the closing date. We will tell you what is realistic for the house and the calendar. If you decide to move forward, we can get the home on the schedule before radon becomes a last-minute issue.
