With the unpredictable weather that the winter brings, it can sometimes get the better of our drywall causing it to crack, break and grow mold. The following article will outline the common types of damage to your drywall during the winter, and will detail how to prevent and repair that damage.

Cracks in your drywall

Most drywall can’t perform well in unheated homes during cold spells in the winter, and if it was poorly installed, there is a higher risk for it to crack. If you have noticed that your drywall has been cracking in scarcely used rooms, try getting a room heater and heat the room to about 10 degrees Celsius to keep the drywall from cracking in the future.

You can usually fix cracks with a drywall compound mixed with a joint compound. If you have cracks in the corners of your drywall, use a flexible, plastic drywall bead product. Keep the room warm every year during the winter to prevent further cracks from forming.

Drywall mold and water damage

Many people overlook mold during the winter because we think it’s too cold for mold to grow and live. Mold does need warmth, moisture, and food to survive – something that the winter provides behind our backs!

When it’s cold outside, we turn on the furnace to heat up the house. We also may use a humidifier to combat the dry air that winter provides. When that warm, moist air runs into cold surfaces like the basement wall or a window, condensation is formed. When you add any sort of carbon-based material, like drywall, mold will attach to it and eat away at it which promotes growth. Mold grows faster in winter than in summer because it’s more hidden away and doesn’t produce a musty smell that gives it away.

How to prevent mold growth in the winter

The most important thing to do is make sure your home is insulated properly. Since warm air rises, your attic should have great insulation to keep the warm air in your living spaces and not in your attic. Having an insulated basement will also prevent condensation from forming when the hot air meets its cold surface.

Always be on the lookout for leaks in your home. When snow and ice accumulate on your roof, you are at risk of having ice dams, which can damage shingles and allow melted snow to enter your home.

Another great tip is to invest in a dehumidifier to place in your basement. If you keep your basement below 60% humidity, you will have less of a risk of mold growing anywhere in your basement, including any drywall you have up.
