Radon mitigation quotes in Normal
Normal is the university half of the twin cities, and that shapes its housing more than anything else: a dense ring of older homes near the campus — many converted to rentals over the decades — surrounded by suburban subdivision growth pushing north and west.
Rental conversions are where radon most often goes unmeasured, sometimes for generations. We introduce Normal homeowners and property owners to independent, IEMA-licensed contractors for free quotes.
Normal and McLean County
Normal routes through our McLean County territory alongside Bloomington, Hudson, Towanda, and Lexington. McLean County sits in EPA’s Zone 1 designation for central Illinois — a screening category for counties rather than a prediction for any specific property.
If the result surfaced in a transaction
The local market splits between owner-occupied family homes and investor-held rental property, and Illinois disclosure duties attach to sales of both: known radon information must be shared. Buyers of converted rentals should assume nothing has ever been tested and order their own measurement during the inspection window — where no test exists, there is nothing for a seller to disclose.
Deeper playbooks: radon in a home sale · what mitigation costs
The housing you’re mitigating
Near-campus housing is largely pre-war on block and brick foundations, frequently subdivided, with partial basements and porch crawl spaces. Ground-contact units are where testing matters most in multi-unit conversions. North-side subdivision stock is conventional poured construction with full basements, sump systems, and clean garage routing.

Normal questions, answered straight
We own a converted multi-unit near campus. One system or several?
Usually one properly designed system rather than separate fixes per unit — soil gas enters through the shared foundation, so a licensed contractor designs suction for the building footprint and then verifies with tests in the ground-contact spaces. Keep written records of tests and any mitigation; they matter for future disclosure.
The upstairs unit tested low. Does that clear the building?
No. Radon concentrations are typically highest in the lowest ground-contact level and dilute with height, so an upper-floor result tells you very little about the garden or first-floor unit. Test the ground-contact spaces, because those are where the number that matters lives.
Do students renting need to be told about radon?
Illinois has moved toward greater radon transparency for tenants in recent years, and beyond any specific requirement, giving renters a current test result is simply the defensible position for an owner. Testing is inexpensive; the records protect you in both directions.
