What are common storage unit mistakes?

Common storage unit mistakes include renting wrong size, leading to paying for unused space or overcrowding that damages items. Many people fail to declutter first, storing junk they will never use. Poor packing is frequent, using weak boxes, not labeling, and not creating inventory, making retrieval difficult. Not using vertical space and failing to disassemble furniture wastes space. Many forget to protect items, not using pallets to keep off floor, not covering mattresses, and not using climate control for sensitive items like wood furniture, electronics, and photos, resulting in mold or warping. Forgetting insurance is mistake, assuming facility covers loss. Choosing facility based only on price without checking security, lighting, and access hours can lead to theft or inconvenience. Procrastinating on organization, stacking heavy boxes on fragile ones, and storing food or hazardous materials that attract pests are common errors. Finally, keeping unit indefinitely without periodic review leads to spending thousands on items worth less than storage fees.
