Are radon levels high in Illinois?
Illinois recommends testing homes for radon rather than relying on location alone. IEMA-OHS publishes county information, but Madison and St. Clair County summaries cannot establish a result for an individual house. An Edwardsville address and a Belleville address each need their own measurement.
Send the complete report when requesting an assessment. Include the device location, test dates and information about any existing system. A number without its report leaves basic questions about the property unanswered.
- Provide the complete radon report.
- Identify any existing vent and fan.
- Describe basement, slab and crawl areas.
Who is licensed to do radon mitigation in Illinois?
Illinois regulates professionals who provide radon services through IEMA-OHS. Verify the license category and current status for the person providing the work. Measurement and mitigation are distinct services; a claim about one should not be treated as proof of the other.
Ask Air Sense to identify the professional and current credential for your project. Keep those details with the estimate. A directory entry should be checked against the name on the work order, rather than relying on a badge reproduced on a website.
- Confirm the responsible professional’s name.
- Check the applicable license category.
- Keep the license details with the proposal.
How much does radon mitigation cost in Illinois?
Air Sense’s published standard active sub-slab range is $1,100 to $3,200. It is a company planning range, not an Illinois-wide tariff or a firm price for every Metro East house. Ask for an assessment-based quote.
For a home with additions or a finished lower level, compare the proposed collection points and route. Electrical arrangements, access and testing responsibilities should be explicit in the scope. Ask for a clear explanation of anything outside the standard proposal.
Will insurance pay for a radon mitigation system?
Your insurer or policy administrator must answer coverage questions for your policy. Do not book work on the assumption that the installation will be reimbursed. Request any coverage determination in writing and keep it separate from the contractor’s scope.
A buyer and seller may also negotiate project costs during a transaction. The service provider’s role is to describe the proposed work and its price; the purchase agreement governs the parties’ commitments.

Questions before you book
Does a mitigation license also prove measurement authorization?
Verify the applicable category for each service. Ask who will conduct the measurement and who will perform mitigation.
What should I keep after installation?
Keep the scope, professional’s details, equipment information, operating instructions and radon verification report in the property records.
Can a seller’s deadline be accommodated?
Share the inspection and closing deadlines before scheduling. Confirm assessment, installation and testing dates separately.
