Radon Mitigation Cost Factors
The cost of your radon reduction system in Chicago, IL, depends primarily on the following factors.
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 Chicago, IL | Description |
|---|---|---|
| Sealing the basement | $497–$5,711 | Half as effective; may require repeated resealing |
| Active suction soil depressurization | $1,242–$3,725 | Most common method; PVC pipe suctions gas from beneath foundation |
| Passive depressurization | $621–$3,104 | Vents radon through PVC piping using pressure differences; low efficiency at high levels |
| Wall-based systems | $621–$3,725 | Cinder block wall creates vented cavity to exhaust radon |
| Ventilation systems | $1,614–$3,104 | Two fans remove radon and vent it outside |
| Water mitigation | $1,490–$6,208 | Uses carbon and aeration to remove radon from water |
Cost by Home Size
The square footage of your house is another cost factor to consider when budgeting for a radon mitigation system. Often, it’s more expensive to install radon reduction systems in bigger homes because the additional space requires more materials. Plus, your contractor may have to spend more time setting up your system, which can drive up labor costs.
Cost by Home Age
Your home’s age can also play a role in your radon mitigation system costs. That’s because older properties often have more foundation damage than newer ones, which need to be addressed when adding a radon reduction system. In turn, this can increase your overall costs.
Radon Mitigation Pro Costs
Before wrapping up your radon reduction budget, be sure to factor in these final expenses.
Permits
Your contractor will need to pull permits before installing a radon reduction system at your home in Chicago. Permit requirements and costs depend on the specifics of your project, but you’ll need at least an electrical permit for this type of job. Your radon detection and reduction specialist in Chicago, IL, should obtain all necessary permits before getting to work.
Labor
Your radon mitigation pro may charge a flat fee or an hourly rate for labor. Either way, the cost should be outlined in your project quote. When hiring a radon mitigation specialist in Chicago, there are a few things to look for. Importantly, your pro should be licensed by the Illinois Emergency Management Agency (IEMA) and carry workers’ compensation and general liability insurance.
Safety Warning
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 more complex installations, you might need to bring in multiple professionals. Additional work involved in radon mitigation projects often includes:
Electrical work: Electricians can handle tasks like running new wiring or installing a radon fan. You can expect to spend between $162 and $504 when hiring an electrician in Chicago.
Encapsulation: An encapsulation pro can seal your crawl space to reduce radon levels in your home. Encapsulation can cost anywhere from $2 to $10 per square foot.
Foundation repair: If your radon mitigation pro discovers damage to your home’s foundation, you’ll need to bring in a specialist to fix it. In Chicago, foundation repair costs between $516 and $2,295.
Does a Radon Mitigation System Increase Home Value?
According to the American Lung Association, 33.5% of radon tests in Illinois come back at or above the Environmental Protection Agency (EPA) “action level.” Adding a radon mitigation system to your home in Chicago can reduce the risk of radon entering your home and getting you sick.
However, that isn’t the only benefit of radon mitigation. If you plan on selling your property, a radon mitigation system can make it more attractive to buyers—and earn you more money on the sale.
