Mold Can Grow In Your Home Even In Winter

Are you concerned about possible winter mold infestation? Discover how you can prevent this problem.

While numerous people think that mold problems disappear during winter, the fungus is a year-round issue.

It thrives in environments between 60 and 80 degrees and grows wherever there’s humidity or moisture. Mold can be problematic during winter since it can grow in your attic, walls, and other hard-to-reach places.

If you’re concerned about possible mold growth during this season, check this out.

Why Mold Grows During Winter

Although summer brings the ideal settings for mold growth, this doesn’t imply you should ignore the fungi in your home throughout winter.

Indoor environments create conditions that promote the growth of mold spores. This is because we usually close our homes during the cold season.

As a result, moisture remains trapped, increasing the levels of humidity. During this season, people engage in various activities that increase the likelihood of mold development.

For instance, people close their doors, windows, and whatever else with the aim of preventing cold from entering their homes.

By closing everything and insulating yourself, you actually produce a suitable environment for the fungus. It’s also likely that you turn the thermostat up, creating a warmer air to combat the winter air.

The downside to having your home too encapsulated with insulation is that it prevents warm air from escaping.

Moreover, the insulation traps in the humidity and condensation for a longer period during this season because people don’t open their homes to the external environment as much.

Areas to Watch for During Winter

While it’s true that heating systems generally make indoor air drier during winter, certain areas of your home may experience intensified humidity levels due to the lack of ventilation. You’ll notice that kitchens and bathrooms are particularly vulnerable to this issue. Other areas include:

  • Windows

Rain and cold typically characterize the winter season. Furthermore, excess moisture arises during this period.

The excess humidity can cause fungal development and you’ll typically discover the fungus on windows after shutting them all winter.

On windows, the fungus is detectable as black mold, which can potentially spread to other areas of the home, causing extensive damage. This can further lead to extra remediation costs.

You may discover mold on windowsills, most of which are aluminum or wooden. While mold needs the presence of humidity and organic matter to grow, you’ll frequently find it on aluminum and wood windowsills. This is because the fungus survives on the organic matter found in household dust.

  • Drywall

Drywall comprises a paper backing, which may promote mold development in the presence of sufficient moisture.

Drywall mold is especially difficult to remove. If the fungus is visible, there’s a high chance that cleaning won’t be worth it and you’d be better off removing and replacing the drywall.

If you discover that only a portion is affected, you need to cut out the affected area, taking care not to disturb the spores.

On the other hand, if you discover the mold on the surface, you could simply clean it using water and common household detergent. Ensure you dry the cleaned surface to avoid mold growth from recurring.

Tips on Preventing Mold during Winter

  • Ensure your humidity level indoors is below 40% during this season. If you decide to use a humidifier as most people do during this time, ensure it doesn’t generate excess humidity.
  • Eliminate potential sources of mold development by cleaning and vacuuming regularly. Pay close attention to areas such as the bathroom and others that are likely to produce considerable moisture.
  • Consider a dehumidifier for your basement. Cool basement walls and floor can be a source of moisture accumulation and the equipment will control humidity levels.

Are you in the habit of closing virtually everything during winter? If so, your home is at risk for mold development. Nevertheless, these invaluable tips will help you prevent the problem.
