Winter Mold: What You Need to Know

When you suspect there's mold in your home, it's stressful, and not just because of the damage mold can cause. You might worry that mold inspection and remediation isn't covered by insurance, but there's a chance it is. In either case, it's worth it to get your mold problem inspected and taken care of.

Can Mold Grow When It's Cold Outside?

Mold can grow even at low temperatures. In the winter, mold usually grows in uninsulated areas of the home that are not heated. Heated air rises to cold, under-insulated places like the attic and can cause condensation, which allows mold to grow. Cold temperatures can slow down mold growth, but won't kill spores. If you have a mold problem in the winter, it'll get worse in the humid spring and summer.

Why Is Winter a Prime Time for Mold?

While winter isn't as humid as summer, mold can still grow in the winter. Besides condensation from heating, another common way for mold to grow in your home is from water damage caused by snow and ice. Mold grows quickly in wet conditions, so when the ice or snow melts, your home will be susceptible to mold growth.

When Should I Hire a Professional?

If you suspect mold, how can you be sure there's a problem? A professional mold inspector can help you find mold in hard-to-reach places and get you started on mold remediation.


Professional mold inspectors:

  • Use special equipment like infrared cameras and moisture sensors to find mold that can't be seen or smelled.
  • Send any mold found to a third-party lab to be tested, so you know what you're dealing with.
  • Assess your home for the cause of the mold.

Mold is quick to spread in high-moisture environments. If you already have some, soon you'll have more. A mold inspection can help you identify the extent of the problem.


Once mold is found, a mold remediation professional can help you come up with a thorough plan that assesses the entire scope of the mold and the root cause. Mold remediation is a thorough process that completely removes mold and addresses the reason the mold grew in the first place. This is the best way to manage existing mold and prevent future problems.
