Radon Mitigation services & cost guide for Naperville, IL
What you'll pay in Naperville depends mostly on your foundation, whether the basement is finished, and where the fan can go. These ranges help you sanity-check a quote.
| Service | Typical range (estimate) | What drives the price |
|---|---|---|
| Radon test (short-term kit or licensed tester) | Kits ~$15–$40; professional test ~$150–$300 (estimate) | DIY vs. licensed tester; real-estate deadlines |
| Sub-slab depressurization system (most common) | ~$1,000–$2,500 (estimate) | Basement vs. slab vs. crawlspace, number of suction points, fan location, finished basement |
| Crawlspace membrane + venting | ~$1,500–$3,500+ (estimate) | Crawlspace size and access |
| Sealing cracks/sump lid (add-on) | ~$100–$500 (estimate) | Number of openings; sealing alone rarely fixes radon (per EPA) |
| Fan replacement on an existing system | ~$300–$700 (estimate) | Fan model, labor |
These are estimates, not quotes. Ranges are rough national/regional estimates compiled from public cost guides and EPA's note that cost depends on house design and the reduction method; they are not prices from any specific Illinois contractor. Ask any contractor for a written, itemized quote before work starts.
