Radon Testing in Champaign, IL

We provide certified, accurate radon testing for homeowners, buyers, sellers, and businesses across Champaign County. Because radon is invisible and odorless, professional testing is a genuine health screening for your household — not a formality.

Short-term testing

A short-term test runs 48 hours to about 7 days — the fastest way to a reading and the standard during real estate transactions. We use continuous radon monitors under closed-house conditions so the result reflects a true worst-case snapshot, not a lucky low reading.

Long-term testing

Radon swings with the seasons, peaking in winter when your home is sealed against the cold. A long-term test of 90+ days gives the most accurate year-round average — the gold standard when a short-term result lands near the action level.

What you get

• A certified continuous-monitor test placed and retrieved by a professional.
• A clear written report with your pCi/L reading and what it means.
• An honest recommendation — if you don't need mitigation, we'll say so.
• If you do, a flat-price quote on the spot with your test fee credited toward the work.
