Radon Came Up in Inspection? Pick the Side of the Deal.
Buyer's agents and listing agents usually need different advice. We keep both paths simple, calm, and aimed at a clean system with paperwork the file can use. Radon mitigation for realtors should match the side of the Illinois radon real estate transaction you are working.
Same company. Different next step.
The Illinois IEMA-OHS real estate radon page is the official state source for real estate testing materials. American Radon Systems handles mitigation, quotes, timing, and documentation once someone is ready to talk about the home.

What to send Bill
Send the property address, radon result if you have it, inspection deadline, closing date, and whether you are on the buyer side or listing side. Photos of the basement, crawlspace, sump area, or existing fan can help Bill give better next steps.

Realtor Radon FAQs
Short answers agents can use when radon shows up during a home inspection. Not legal advice.
I am buying a house that tested high for radon. What do I do next?
Call Bill with the inspection result, property address, and inspection deadline if you have one. He can walk through the number, quote the home under contract, and talk through options such as a seller credit or concession. That gives you a real number before closing and helps you understand the system you will own. Mitigation can often be done before or after closing depending on the deal and calendar.
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.
Why should sellers call early after a high radon test?
Early action protects options. Bill can look at the home, price the work, and get the job on the calendar if you move forward. Calling early gives you more options and keeps the closing conversation simpler, especially if the buyer later wants install before the closing date.
Can a buyer get a radon mitigation quote during the inspection window?
Yes. That is one of the best times to call. Bill can look at the home, explain the likely mitigation plan, and give a real quote before the inspection deadline so the buyer understands cost before closing.
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.
What do most realtors recommend when a buyer’s inspection finds radon?
Buyer’s agents often want the buyer to understand the number, get a real quote for that house, and decide whether a credit, seller-paid install, or post-closing install fits the deal. Quality, routing, and warranty matter because the buyer is the one who will own the system. Bill can quote the property and work with the agent on timing.
Who usually pays for radon mitigation in a home sale?
It is negotiable. Sometimes the seller pays for install before closing. Sometimes the buyer receives a credit or concession and hires the mitigator. Local custom and the specific contract drive it. We price the work the same either way and focus on a system that is done right.
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.
