Spring Radon Myths: What Winnipeg Homeowners Often Get Wrong

As the weather warms up in Winnipeg, many homeowners stop thinking about radon.

Windows are open. Fresh air is moving through the house. It feels like indoor air concerns have passed with winter.

But when it comes to radon, spring can create a false sense of security.

Here are a few common myths and what’s actually true.

Spring air can make your home feel safer, but radon levels don’t disappear.

Myth #1: “If I open my windows, radon isn’t a problem anymore”

Opening windows can reduce radon levels for a short time.

But it doesn’t eliminate the source.

Radon is a gas that enters your home from the ground through cracks, sump pits, and other small openings. As long as those entry points exist, radon can continue to enter the home, accumulating when it is closed up again.

What this means:
Fresh air can lower radon levels temporarily, but it does not solve the problem.

Myth #2: “Spring is a bad time to test for radon”

This is one of the most common misconceptions.

Radon can be tested at any time of year.

While levels are often higher in winter, a spring test can still give you a clear signal, especially if results come back elevated.

If radon levels are high in spring, it is often a strong indication they could be even higher in winter.

That is because homes are more sealed in colder months, which allows radon to build up more easily.

What this means:
You do not need to wait. Testing now still gives you useful, actionable information.

Should You Test for Radon in the Spring?

Yes, testing in the spring still gives you reliable information.

The most common mistake we see is homeowners waiting until winter to test. Radon levels can change throughout the year, but testing at any time will still give you a clear picture of your home’s levels.

If levels come back elevated in spring, it is often a strong indication that levels could be even higher during winter, when homes are more sealed, and radon tends to build up.

You do not need to wait for colder weather to take action.

Many homeowners start with a short-term screening to get a quick sense of their levels. If needed, a longer-term test can provide a more complete picture over time.

The most important thing is to test.

Myth #3: “Radon is only a problem in older homes”

Radon can affect homes of any age.

In fact, many newer homes are built to be more airtight, which can allow radon to accumulate more easily.

Some newer homes include a rough-in pipe for future mitigation, but that system is not active unless a fan is installed.

What this means:
Newer does not mean safer. Testing is still the only way to know.

Myth #4: “I’ll deal with radon later, when it matters more”

Spring is when many homeowners start planning renovations or spending more time improving their homes.

That makes it one of the best times to think about radon.

If you are finishing a basement, addressing radon early, whether through testing or mitigation, can save time, cost, and disruption later.

What this means:
It is easier to plan for radon now than to fix it after the space is finished.

The Bottom Line

Spring can make radon feel like less of a concern.

But the underlying risk does not change with the season.

If anything, spring is a good time to get clarity before your home is sealed up again next winter.
