As colder weather approaches, it’s a good time to prepare your storage unit and belongings for the winter months. Even in Texas, temperatures can change quickly, and occasional freezes, moisture, and winter storms can affect improperly stored items.A little preparation can help keep your belongings organized and protected until you’re ready to use them again.

1. Use Plastic Storage Totes

Consider replacing cardboard boxes with sturdy plastic totes, especially for items you plan to store throughout the winter. Plastic containers provide an added layer of protection against dust and moisture and are easy to stack.Make sure everything is completely clean and dry before placing it inside a tote. Label each container so you can quickly find what you need later.

2. Keep Items Off the Floor

Whenever possible, use shelving or pallets to elevate boxes and other belongings. Keeping items off the floor can improve organization and provide extra protection if moisture finds its way into the unit.Place heavier containers on the bottom and lighter or fragile items toward the top.

3. Prepare Furniture for Storage

Clean and thoroughly dry furniture before putting it into storage. Instead of wrapping furniture tightly in plastic, consider using breathable furniture covers or moving blankets. These can help protect against dust while allowing some airflow.For tables and other furniture that can be safely disassembled, removing legs or other components may also save valuable storage space.

4. Drain Equipment That Contains Water

Freezing temperatures can cause water left inside hoses, pressure washers, lawn equipment, and other seasonal items to expand.Drain water from equipment before storing it for winter and follow the manufacturer's recommendations for long-term storage.

5. Remove Batteries

If you're storing battery-operated seasonal decorations, tools, toys, or electronics, remove the batteries first. Batteries left inside devices for extended periods can leak or corrode and potentially damage the item.Store batteries separately in an appropriate location.

6. Clean Before You Store

Don't put dirty or damp belongings into storage for several months. Clean outdoor equipment, camping gear, furniture, clothing, and other seasonal items and allow everything to dry completely.Avoid storing food, liquids, or other items that could attract pests or spoil.

7. Consider Climate-Controlled Storage

Some belongings are more sensitive to temperature and humidity changes than others. Electronics, photographs, important documents, musical instruments, wood furniture, artwork, and certain collectibles may benefit from a climate-controlled environment.If you're unsure whether an item needs climate-controlled storage, consider how it would handle several months of changing temperatures and humidity.

Prepare Now for an Easier Spring

Winterizing your storage unit doesn't have to be complicated. Spending a little extra time cleaning, organizing, elevating, and properly packing your belongings can make a big difference when it's time to retrieve them.And when warmer weather returns, you'll appreciate opening your storage unit to find everything organized and ready to use.Need additional storage space this winter?
