The average radon mitigation system cost in Columbus is $1,020, though it commonly ranges from $849 to $1,195. The price you’ll pay comes down to a few key factors, including the mitigation method you pick and the size of your house. Here’s how to estimate the total cost of radon reduction in Columbus.
Radon Mitigation Cost Factors
Here are the most important factors to consider when budgeting for radon mitigation in Columbus, OH.
Cost by Method
The cost of a radon mitigation system depends on the chosen approach, which might be sealing the basement, depressurization, or lower-level pressurization. The depressurization method happens in one of two types: active suction (soil depressurization) or passive depressurization.
Here’s what to expect for pricing by radon mitigation method:
| Method | Cost Range in Columbus, OH | Description |
|---|---|---|
| Sealing the basement | $396–$4,551 | Half as effective; may require repeated resealing |
| Active suction soil depressurization | $989–$2,968 | Most common method; PVC pipe suctions gas from beneath foundation |
| Passive depressurization | $495–$2,473 | Vents radon through PVC piping using pressure differences; low efficiency at high levels |
| Wall-based systems | $495–$2,968 | Cinder block wall creates vented cavity to exhaust radon |
| Ventilation systems | $1,286–$2,473 | Two fans remove radon and vent it outside |
| Water mitigation | $1,187–$4,947 | Uses carbon and aeration to remove radon from water |
Cost by Home Size
In addition to the mitigation method you choose, the size of your house can also affect your costs. Installing a radon reduction system in a bigger home often requires more labor and materials, which can lead to higher costs. If you have a larger-than-average home, prepare to spend an additional $495 to $1,484 on this project.
Cost by Home Age
Your home’s age can play a role in your costs, too. Since older houses often have more foundation damage than newer builds, contractors may have to put in extra work to correct these issues and prevent radon from getting into your home. If so, your final bill could go up.
Radon Mitigation Pro Costs
Before tallying up your final costs, there are two more expenses to consider: permits and labor.
Permits
Some types of radon mitigation systems use an electric-powered fan to remove radon from your home. If you choose one of these systems, your contractor will need to get an electrical permit from the City of Columbus. Here, electrical permits for residential properties run between $140 and $275.
Labor
Radon detection and reduction specialists in Columbus, OH, should include their labor rates in their project quotes. Depending on the contractor, it could be listed as a flat fee or an hourly rate.
Licensing and Certification
Radon mitigation professionals in Columbus must be licensed by the Ohio Department of Health (ODH). And while it’s not legally required, it’s also smart to hire a pro who’s certified by either the National Radon Proficiency Program (NRPP) or the National Radiation Safety Board (NRSB).
Angi Tip
Exposure to radon over a long period of time can cause serious health problems, including lung cancer. Lowering radon in your home requires professional knowledge and skills only available by hiring a radon mitigation pro.
Additional Pros to Consider Hiring
For some radon mitigation projects, you’ll need to bring in multiple contractors to handle different parts of the job. This often includes:
Electrical work: A licensed electrician can hook up your radon fan, install new wiring, and make sure your system’s electrical components are working correctly. In Ohio’s capital, hiring an electrician costs between $145 and $446.
Foundation repair: You might also need a specialist to fix cracks or other damage to your home’s foundation. In Columbus, the average foundation repair job costs $2,290 to $8,678.
Encapsulation: Your radon mitigation contractor might recommend encapsulation—which involves sealing your crawl space—to stop radon from getting into your house. This can add thousands of dollars to your project total.
Does a Radon Mitigation System Increase Home Value?
Radon poses serious health risks throughout Ohio, but it’s a particular issue in the Columbus area. In fact, one ZIP code in nearby Licking County has the highest levels of radon in the country, according to a study from Harvard University.
If you live in Columbus, installing a radon mitigation system is a good way to protect yourself from this dangerous, cancer-causing gas. But it’s also an investment in your home’s marketability. If you sell your house, many buyers will appreciate that it has a working radon reduction system—which can help you earn more money on the sale.
