How to pack your items for climate-controlled storage

Pack items for climate-controlled storage with care to ensure their preservation. Begin by cleaning and thoroughly drying all items to prevent mold and mildew.

Use sturdy, high-quality boxes for packing, and label each box clearly. Wrap fragile items in bubble wrap or packing paper. Use furniture covers or blankets for larger pieces.

For added protection, place silica gel packets inside boxes to absorb any residual moisture.

Stack boxes strategically, with heavier ones on the bottom.
