Is mold prevention in the winter easier than in summer? Only marginally, it turns out. Seasonal outdoor conditions have little effect on mold growth inside the enclosed environment of a home. Airborne spores that spawn mold may infiltrate the house at any time of year. What's more, active mold growth can survive at temperatures far lower than typically maintained inside an occupied house during winter. Still, controlling certain factors specific to the cold season can at least reduce the odds of household mold contamination. Here are five ideas for mold prevention in the winter:
- Humidify sparingly. Winter air is often dry and irritating to certain individuals. To alleviate these symptoms, humidifiers are commonly utilized to add water vapor to indoor air. Many portable humidifiers do not allow specific relative humidity settings, however, and rooms may become over-humidified. Moisture is a primary trigger for active mold growth. Maintain indoor humidity levels at 60% or below to discourage mold.
- Run ceiling fans in the “reverse” (clockwise) mode for winter. A ceiling fan rotating clockwise pulls warm air upwards and pushes it across the ceiling and down walls and windows. This air circulation dries out condensation on these surfaces, particularly overnight, eliminating another source of mold-triggering moisture.
- Upgrade your insulation. Some houses have minimal or no insulation inside exterior walls. Condensation forms on and inside cold, uninsulated walls in contact with warm, moist indoor air. To prevent mold growth, wall insulation should meet current Department Of Energy recommendations for type and amount.
- Check the attic. While your roof shingles may shed summer rain effectively, the slow, stationary seepage from melting snow on the roof is another matter. Roof leakage due to snow melt or ice dams on the roof is a common cause of mold growth in the attic.
- Dry wet areas. Many parts of the house—windows, mirrors, plumbing pipes— tend to be chronically damp in winter due to ongoing condensation. Quickly removing moisture with a towel prevents these areas from becoming potential focus points for mold growth.
As winter sets in, taking proactive steps to prevent mold growth in your home is crucial. By controlling humidity, ensuring proper air circulation, upgrading insulation, checking your attic, and drying wet areas, you can significantly reduce the risk of having to call your local mold remediation company for help.
