Quick scheduling

We do not make you wait weeks for a test or an install date.

Locally owned

One shop, one service area, no franchise call center.

A one-time test tells you what your radon level was during that test period. A continuous monitor tells you what it is doing right now and how it changes across seasons, weather and even which windows got left open. For Des Moines homeowners who want an ongoing answer instead of a single number, that is the difference a permanently installed device makes.

We install the monitor in the right spot, set it up correctly, and walk you through reading it, so it is actually useful and not just a blinking light in the basement. Quick scheduling means we can usually get a device installed well before your next test window closes.

What a continuous monitor does differently

A continuous radon monitor samples the air on an ongoing basis, not once. That means you can catch a spike after a sump pump repair, a foundation crack, or a change in how the house is sealed up for winter, instead of finding out a year later when something prompts you to test again.

Where devices get installed

Same general rule as short-term testing: the lowest livable level of the home, away from drafts, exterior doors and HVAC vents that would skew the reading. In homes with a finished basement in Polk County, that is usually a corner of the main living space rather than a mechanical room.

Reading and maintaining your monitor

Most continuous monitors show a current reading and a running average. We explain what normal fluctuation looks like versus a reading that means it is time to call, and most units just need an occasional battery change or calibration check to keep giving you an accurate picture.

Who needs a permanent device versus a one-time test

If you already have a mitigation system installed, a continuous monitor is a good way to confirm it keeps working over the years rather than waiting for another scheduled test. If you have never tested before, we usually start with a standard short-term or long-term test first and go from there.
