What to Know About Winter Mold

Updated: Feb 17, 2022

Rain, snow, sleet, hail. The wet and cold of winter have arrived. This is the prime time for mold growth due to all the extra moisture. To keep the yuck and headache of mold at bay, there are some simple solutions that can offer prevention.

Watch for Leaks & Make Repairs Quickly

Common areas to check for leaks include windows, exterior-to-interior doorways, and areas by skylights and swamp coolers. Be sure to carefully check seals around windows and doors.
Regularly check around plumbing and underneath sinks. These are spots where leaks often stay hidden.
Be observant of pipes, windows, and walls. Extra moisture can quickly be absorbed by drywall and wood creating a perfect environment for mold growth. If you notice condensation accumulation, dry the area immediately. If you have a basement, check it often for signs of moisture.
Do not wait to make repairs. If you see a leak or have a suspicion there may be a problem, fix the damage immediately to avoid the risk of water damage.

Ventilate

Always use exhaust fans or open a window in bathrooms, kitchens, and laundry rooms when moisture is present.
Check that your clothes dryer is in working order and properly venting to the outside.
Set ceiling fans to turn clockwise. This pulls cold air up and pushes warm air down. It also helps to circulate air, preventing condensation on walls, windows, and doors.

Keep Humidity in Check

Keep humidity levels in the home below 40 percent. Monitor humidity levels and temperature consistently. Areas that are too moist run the risk of possible mold growth. There are tools available to help you keep things balanced between the various rooms in your home.

Properly Insulate

Be sure to winterize your pipes. If temperatures are dropping below zero. Pipes should be insulated both inside and outside. This will prevent possible cracks and breaks.
Wall insulation should meet the Department of Energy recommendations for type and amount. It may be necessary to upgrade your insulation. Minimal or no insulation inside exterior walls means possible condensation formation and extra moisture along. Moisture along with wood and dust creates a perfect breeding ground for mold.

Mold can begin forming in as little as 24 hours and spread even more quickly. The winter months require some diligence in avoiding possible mold growth but, limiting this type of disaster is possible with some simple preventative measures.
