Radon Mitigation Cost in Cincinnati
Ohio's health department doesn't publish a price range, so here are the closest credible benchmarks, plus the long-term costs most Cincinnati quotes leave out.
Benchmark range
About $800 – $2,500
National Radon Program Services, an EPA-funded program, puts the U.S. average at about $1,200. The University of Kentucky's radon program, in neighboring Kentucky, gives $1,200–$2,500 for an existing home.12
The benchmarks
| Source | Price |
|---|---|
| National average, existing home (National Radon Program Services)1 | About $1,200 |
| National typical range (same source)1 | $800–$2,500 |
| Existing home, University of Kentucky BREATHE program2 | $1,200–$2,500 |
| Activating a passive system (UK BREATHE)2 | $500–$600 |
| Replacing a radon fan, parts and labor (EPA)3 | $200–$350 |
We couldn't find an Ohio government source that publishes a mitigation price range, so these come from a national EPA-funded program, a Kentucky university program and EPA. Your Cincinnati bids are the real number.
Built recently? Check for a passive pipe
Radon-resistant new construction costs roughly $600–$800 when a home is built, according to the University of Kentucky's BREATHE program, and turning that passive pipe into an active fan system averages $500–$600.2 If your home was built with radon-resistant features, ask an Ohio-licensed specialist whether activation is an option before paying for a full system.
Comparing bids the way EPA suggests
EPA's consumer guide says to weigh what you get for the money, not just the price:3
- A less expensive system may cost more to operate and maintain.
- A less expensive system may look worse in your home.
- A more expensive system may be the right one for your house.
- The quality of the materials affects how long the system lasts.
Many contractors give free estimates but may charge for diagnostic tests, so ask up front.3

- Electricity. A radon fan draws about as much as a 60–90 watt bulb running all the time.1
- Heating and cooling loss. Most systems pull out some conditioned air, which can raise utility bills depending on climate, system type and how the house is built.3
- Fan replacement. EPA puts it at about $200–$350 including parts and labor.3 Fans typically carry 5-year warranties and last 10 to 15 years.1
- Retesting at least every two years.1
Selling a Cincinnati home
Ohio's Residential Property Disclosure Form, required under ORC § 5302.30, asks sellers whether they know of radon gas (Yes, No or Unknown) and, if yes, to give the level if known.45 If your home tested high, a written bid or a finished system with a post-mitigation test gives buyers something concrete.
Make sure the price includes a licensed crew
In Ohio, a business needs a mitigation contractor license and on-site supervision by a licensed mitigation specialist.6 A cheap bid from an unlicensed outfit isn't a bargain if a buyer's inspector questions the system later.
Common questions
How much does radon mitigation cost in Cincinnati?
Ohio doesn't publish a range. National Radon Program Services puts the U.S. average at about $1,200 (typical range $800 to $2,500), and the University of Kentucky's radon program gives $1,200 to $2,500 for an existing home.
How much does it cost to replace a radon fan?
EPA puts fan replacement at about $200 to $350, including parts and labor.
What does it cost to activate a passive radon system?
The University of Kentucky's BREATHE program says activating a passive system averages $500 to $600.
Is the cheapest radon bid the best deal?
Not necessarily. EPA notes that a less expensive system may cost more to operate and maintain, and that material quality affects how long a system lasts.
Do Ohio sellers have to disclose radon?
Ohio's Residential Property Disclosure Form asks whether the seller knows of radon gas and, if so, the level if known.
Please note: Ohio requires a license to give professional or expert advice on radon testing, exposure or mitigation. This page is general information summarized from public agencies, not professional advice. For advice about your home, talk with an ODH-licensed professional.
