Holiday Decorations + Damp Basements = A Perfect Storm for Mold

How to Protect Your Home (and Keepsakes) from Hidden Mold Growth

The holidays bring out the best decorations — and sometimes, the worst conditions for mold.

If you’re pulling dusty boxes of lights, ornaments, or fabric decorations out of a cool, humid basement, you might be welcoming more than just festive cheer. Cardboard boxes, fabric decorations, and stored clutter can absorb moisture, and once humidity rises above 60%, mold can begin to grow — not just on storage boxes, but on your keepsakes, walls, and even in the air.

At Lew Environmental, we help homeowners and property managers stay ahead of mold and moisture issues — before they become costly problems. Here’s how to protect your home, your air quality, and your holiday spirit.

Mold Prevention Tips for Holiday Storage

Swap Cardboard for Plastic

Cardboard absorbs moisture quickly, making it a perfect breeding ground for mold spores. Switch to sealed plastic storage bins to keep contents dry and protected year-round.

Keep Boxes Off the Floor

Avoid storing bins directly on concrete or near exterior walls where condensation and cold spots are common. Use shelves or pallets to lift storage off the floor.

Control Basement Humidity

A dehumidifier can make a huge difference. Aim to keep relative humidity below 60% to prevent mold growth. Consider using a humidity monitor to keep tabs on conditions.

Inspect Decorations Before Use

As you bring boxes upstairs, inspect them for musty odors, visible mold, or dampness. If you spot mold, it’s safest to toss the box and its contents rather than risk bringing spores into your living space.

Make This Holiday Season a Healthier One

Whether you’re storing decorations or dealing with long-term basement moisture issues, a few proactive steps now can protect your home all winter long.
