Radon testing
Northern Illinois and southern
Wisconsin sit on a lot of radon.
We have run 2,385 of these. The
readings are hourly across 48 hours of closed-house conditions, measured against the EPA
action level of 4.0 pCi/L — a result you can hand to anybody, under our IEMA licence.
How it works.
Forty-eight hours, closed-house conditions, and a report you can hand to anybody.
01Monitor placed at the inspection
02Closed-house conditions for 48 hours
03Hourly readings, not a single average
04Collected and analysed
05Report the same day it comes off
06Result against the EPA 4.0 action level
A continuous monitor records every hour, which is what makes the result defensible — a single
number from a charcoal kit cannot show that a window was opened halfway through.
What it costs.
It depends on the house, so the quote gives you the real number. Here is the honest
version of what moves it.
One monitor
Covers most homes — a single lowest-level living space.
Additional device
Sometimes
A large or split-level foundation may need a second. We tell you at placement, at the
house, not afterwards on the invoice.

IEMA licensed
Illinois requires a licence to measure radon for a real estate transaction. We hold it.
