3 Tips for Preventing Mold Growth by Controlling Humidity

Mold requires three things to grow: moisture, warmth, and food. Winters in the northeast are not exactly known for their tropical bent, but there are still ways that mold can grow in your home during the winter. Poor insulation, water leakage, and home heating can create the perfect conditions for mold growth in your attics or walls. Here are some tips to keep the insides of your walls clean, and not looking like bread that was left in the pantry for too long.

  • Control the humidity in your home. Some of us use humidifiers to prevent our homes from becoming bone-dry due to heating. But humidifiers can sometimes raise humidity too high. While 60% is alright during summer, over 40% humidity in winter is enough for water to start condensing on your windows– a good sign that they’re working, but a bad sign for mold prevention). Condensation on your windows can drip onto your walls and soak in.
  • In the same vein, try to vent bathrooms to the outside. Hot showers create a good deal of steam, and keeping it inside in the winter can create paradise for mold spores. Venting your kitchen may also be a good idea if you’re cooking up a storm. Keep in mind that venting to the attic will just relocate the problem from your walls to your attic; so be sure to vent outside.
  • Try to not store anything mold uses as food in humid parts of your home. This includes fabric and paper items like clothing, towels, books, and magazines. If you can’t control the humidity in those rooms, try to remove the items to a drier part of the house.

Controlling humidity indoors can go a long way in keeping mold from spreading through your walls. Check back for more ways to prevent mold growth this winter!
