Which side of the deal are you on?
We handle the radon system: the price, the timing, and the paperwork. For the state's official papers on testing during a sale, use the Illinois IEMA-OHS real estate radon page.

Representing the seller?
- Call as soon as the buyer’s radon test comes back high
- Bill can look at the home and give you a realistic price
- Calling early gives the seller more choices
- A finished system with paperwork takes radon off the repair list
- Waiting can squeeze the schedule before closing
Representing the buyer?
- Call during the inspection window
- Get a real price before the inspection deadline
- See the cost, layout, warranty, and timing
- A credit may let the buyer pick the company and do the work after closing
What to send Bill
Send the property address, the radon result if you have it, the inspection deadline, the closing date, and whether you’re on the buyer side or the listing side. Photos of the basement, crawlspace, sump, or any radon fan help Bill too.
What both sides get
An honest schedule
We tell you what we can get done before the closing date.
A neat install
We plan the pipe route for that home.
Paperwork
You get written paperwork and the warranty for the sale file and the home records.
Homeowners can start at our buying or selling page, which is written for them. To see what an install includes, read about our radon mitigation services.

Radon questions agents ask
Short answers agents can use when radon shows up during a home inspection. They are 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 and quote the home under contract. That gives you a real number for the conversation with your agent and attorney. Decisions about credits or concessions belong with them, and a firm quote makes that conversation easier.
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.
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.
Does Illinois require a radon test before selling a home?
No. The Illinois Radon Awareness Act does not require a seller to test or to mitigate. It requires the seller to give the buyer the IEMA-OHS pamphlet Radon Testing Guidelines for Real Estate Transactions and a Disclosure of Information on Radon Hazards form that states what the seller actually knows, including any earlier elevated results and whether the home was mitigated. Because that disclosure only covers what the seller knows, buyers usually test during the inspection period.
