Preventing Winter Mold and Mildew

While winter weather is notoriously cold with low humidity, the climate inside your home is far more comfortable. In fact, your home environment has a warmer temperature and more reasonable humidity.

While these conditions make for a cozy space on the dreariest days, they also make your home hospitable to mold and mildew growth. Cleaning up this growth can be a chore, so preventing winter mold and mildew is a top priority.

Why Winter Is Prime Mold Season

Mold and mildew are common throughout the year, but they can be even more problematic in the winter months. One reason for this is because warm air from your heater can create condensation around heating vents, windows, and other areas. The heat and humidity in your home aren’t limited to these areas.

In fact, because the conditions are ideal for fungi to grow, you might spot growth in areas where you least suspect.

Common Winter Mold Hotspots in Your Home

Condensation is one of the top reasons for mold growth on windowsills and frames. This is because the temperature difference between the frigid indoors and your indoor space produce moisture. This same condensation effect can happen near heating vents throughout your home.

In addition, other areas of your home are perfect for fungal growth throughout the year. These include high-humidity areas like the laundry room, bathrooms, and basement.

How to Prevent Mold and Mildew During Winter

The best way to handle mold and mildew is to prevent them from growing in the first place. You might assume that cleaning your house regularly with bleach will keep the fungi away, but this isn’t the case. In reality, bleach just removes the color of the fungi.

Here’s how to prevent mold and mildew in the winter and throughout the year:

• Open the windows periodically. This improves air circulation to even out humidity levels in your home. In addition, it provides a route for mold spores to leave your home.
• Improve ventilation in your home. The exhaust fans in your laundry room and bathrooms should be used frequently. Each time you shower, bathe, or run a load of laundry, you should turn on the exhaust fans. Keep them on for at least 15 minutes after you’re done.
• Open the blinds. You might be inclined to keep the blinds and curtains closed on cold days. After all, they provide some level of protection against the cold permeating through the windows. However, they also trap cold air near the windows, which contributes to the condensation problem. Letting the sunlight in promotes even temperature distribution. Plus, natural sunlight can prevent mold growth.
• Clean regularly. Keeping your home clean is essential for keeping your home free of mold and mildew. While bleach isn’t recommended for killing fungal growths, white vinegar is effective and safe for use on many surfaces.

Long-Term Strategies for a Mold-Free Home

There are two main strategies for a mold-free home. First, you need to keep everything in your home as dry as possible. Mold needs moisture to thrive, and this includes humidity in the air as well as liquid water.

In addition to running the ventilation system, take a minute to wipe down the shower walls after showering. Wipe off the counter and sink in the kitchen and bathroom after each use. If you’re aware of a slow plumbing leak, fix it as soon as possible. Deal with condensation by increasing air flow.

Second, you need to keep everything as clean as possible. This involves regularly cleaning your home, including using vinegar to kill fungi. Ideally, the moist or high-humidity areas of your home should be cleaned weekly. Fungal spores can live in your air ducts, so change the air filters every few minutes. The air ducts should also be cleaned every three to five years.

When to Call a Professional

Small areas of mildew and mold growth can be cleaned by you or professional cleaners. If you’re dealing with a larger area of concern, it’s time to schedule professional mold remediation. This minimizes health risks to you and reduces the spread of mold spores throughout your home.

If you don’t have time to give housecleaning the attention that it deserves, it makes sense to hire a professional cleaning crew. Remember that mold and mildew have potentially serious health consequences. In addition, they can lead to thousands of dollars or more of property damage in some cases.
