Continuous Radon Gas Testing ($300)
Radon is a colorless, odorless radioactive gas and the second leading cause of lung cancer in the United States. It cannot be detected without a test, and it is found in elevated concentrations in a significant percentage of Illinois homes. Every professionally conducted test is recorded with the Illinois Emergency Management Agency.
No trip surcharge when bundled with a home inspection! (No surcharge even without an inspection).

Is Radon Testing Worth It for You?
An honest breakdown of the pros, cons, and when the risk justifies the cost.
Pros
- Elevated levels found before closing put the seller on the hook — you can negotiate for mitigation or a price reduction before you own the home.
- A professionally monitored test carries full weight in negotiation.
- Mitigation costs are predictable: under $2,000 for a full basement, approximately $3,000 with a crawl space.
Cons
- Short-term test kits are available at hardware stores for under $30. If you are willing to test after purchase and absorb any mitigation cost yourself, the pre-purchase test may not change your decision.
- If levels come back low, the investment yields no financial return.
When the Risk Is High
- The home has a basement (radon accumulates in lower levels)
- The home is in a zip code with elevated radon history — use our radon zip lookup tool above for local data specific to your address
- The home has been closed up for an extended period
When the Risk Is Low
- Slab-on-grade construction with no basement
- You are in a low-radon area, willing to self-test after purchase, and mitigation cost would not affect your decision
