Radon testing in Windsor-Essex
There are three ways to test a home in Windsor-Essex: a long-term kit, a library (opens in a new tab) monitor, or our test by mail.
Health Canada (opens in a new tab) only goes by a long-term result, one that runs at least 91 days. A long-term kit or our test by mail gives you the number to act on.
At least 91 days

Essex County Library (opens in a new tab) lends a digital radon monitor for up to 3 weeks, usually in the colder months. It's a short look, not a long-term test. We haven't confirmed whether City of Windsor residents can borrow one. We also couldn't confirm whether Windsor Public Library lends them.
How our test by mail works
Our test is long-term. It uses an alpha track detector (or dosimeter), and an independent lab analyzes it. It's $300 plus HST, with shipping both ways included. That covers the detector, the lab fees and a written result.

We email you the written result, then call to go over it with you. How long the result takes depends on the mail getting the detector to the lab.
What a kit or library loan can tell you
A long-term kit gives you a number
A long-term kit, run for at least 91 days, gives you a number you can compare with Health Canada (opens in a new tab)'s guideline of 200 Bq/m³.
A library monitor gives you a short look
The library monitor shows you a reading over a few weeks. Health Canada says short-term results aren't right for deciding on a fix. So if a short reading comes back high, follow it with a long-term test.
Where to put it
Either way, put it on the lowest level you live on, in a room you use more than 4 hours a day. Keep it at least 1 m from vents, windows and doors.
If it comes back above 200
If a long-term result comes back above 200 Bq/m³, here's what to do next.
- 1The test, off the floor, on the lowest level you live on.
- 2At least 1 m from doors, windows and vents.
When to have a professional test
A professional test makes sense when you want a certified pro behind the result, such as before you sell. Ours comes by mail, and we go over the written result with you. How our test by mail works.
Testing around a home sale
Health Canada says to test before you sell or after you buy.
After a system goes in
To check it worked. Every system we put in comes with a 91-day lab test after the install. C-NRPP (opens in a new tab) also suggests your own long-term test in the next heating season.
Already have a kit or library result?
We'll quote a fix from it, with no retest needed for the quote. If it was a short test, Health Canada still says to base the decision on a long-term one.
Our radon professional is C-NRPP certified for residential radon measurement and residential mitigation. The measurement certificate, 202897, is on the C-NRPP registry, so you can check it before you book (opens in a new tab).
Ask for a test by mailShort test or long test?
If you're only going to run one test, we'd make it a long-term one. Health Canada says the fall or winter is the best time. That's when windows stay shut. Short vs long radon tests covers where and when to test.
What your number means
Health Canada says to fix it if your long-term result is above 200 Bq/m³. What your radon number means covers the rest of the scale, and got a high result? covers what to do next.
Ask for a radon test by mail
Tell us about your home and when you'd like to start, and we'll call you to set up the test. We answer every call and form message ourselves, within 24 hours.
