Radon Testing

Radon Testing in Boulder, CO

Find out your radon level first. Decide after.

Every Radon Decision Starts Here

A test tells you whether your home needs a system at all. Boulder County sits in EPA Zone 1, and the county estimates about one in two homes here has an elevated level, so the EPA recommends testing every home, including homes that already have a radon fan.

You can test on your own. Boulder County lists the ReSource Tool Library at 6400 Arapahoe Road in Boulder and the CSU Extension office in Longmont as places to buy short-term kits, and most hardware stores carry them. The State of Colorado also gives out free mail-in kits while supplies last.

If you'd rather hand it off, or you need a number you can trust for a big decision, we place the test, read it and explain what the result means for your house. Call (983) 200-7452.

Types of Radon Tests

Different tests answer different questions.

Short-Term Tests

Two to seven days with the house kept closed. Quick, inexpensive and the normal place to start.

Long-Term Tests

Ninety days or longer, for a truer picture of your average across seasons.

Continuous Monitors

Electronic monitors that record hour-by-hour readings, useful when a result has to hold up, like in a home sale.

Post-Mitigation Tests

Run after a system goes in to document how far the level dropped.

How a Radon Test Works

Set the Test

Place it on the lowest level you live in, away from windows, vents and outside walls.

Keep the House Closed

Normal coming and going is fine. Leave windows and doors shut otherwise.

Get the Number

Results come back in pCi/L. The EPA says fix at 4.0 or above and consider fixing from 2 to 4.

Plan the Fix

If the level is high, we design a system for your foundation and give you a written price.
