Using a self-storage unit is a great way to create more space at home, keep your items secure, or manage a transition like a move or renovation. But if you're not careful, common storage mistakes can lead to lost time, damaged items, or even extra costs.
Before you start searching for storage units near you, it’s important to know what to avoid before you start storing. Here are the top 10 mistakes people make when using self-storage—and how you can avoid them.
1. Not Choosing the Right Size
The first mistake most people make when selecting a unit is renting one that’s too small, only to realize later that they need more space. Others overpay for a unit that’s larger than necessary. Using Granite Mountains' storage size calculator will help you estimate the right self-storage unit size to fit your needs.
2. Skipping Temperature Control for Sensitive Items
Electronics, artwork, wood furniture, and important documents can warp or degrade in extreme temperatures. If you’re storing items long-term or during hot months, opt for a temperature-controlled unit to avoid damage to your valuables.
3. Using Weak or Damaged Boxes.
Old, flimsy boxes are prone to collapse or tear. Invest in sturdy boxes or plastic bins to ensure your belongings stay safe, especially when stacking. Visit our office to purchase some new, sturdy boxes as well as other packing necessities.
4. Failing to Label Boxes
When it’s time to retrieve an item, you won’t want to dig through a pile of unlabeled boxes. Ensure that each box is clearly labeled on multiple sides and maintain a master list of the contents within each box.
5. Packing Without a Plan
Randomly tossing items into your unit can lead to wasted space and damaged belongings. Store heavier items on the bottom, lighter ones on top, and keep an aisle for easy access.
6. Storing Prohibited Items
Avoid putting anything flammable, perishable, or illegal in your unit. Granite Mountain provides a list of prohibited items. When in doubt, just ask!
7. Neglecting Insurance
Don’t assume your belongings are automatically covered in the event of an accident. Some renters' or homeowners’ insurance policies may cover storage, but if they do not, Granite Mountain offers self-storage insurance through our partnership with Bader for just pennies a day.
8. Overlooking Security Features
Not all storage facilities are equal. Look for storage units with gated access, security cameras, lighting, and no foot traffic. Our self-storage facility in West Valley City provides round-the-clock surveillance to enhance your peace of mind.
9. Not Using Pallets or Shelving
Keeping boxes directly on the floor can expose them to ground temperature changes. Use pallets or shelves to elevate items and improve airflow inside your unit.
10. The Importance of Regularly Checking Your Unit
Even the most secure units benefit from an occasional check-in. Visit your self storage unit every so often to ensure everything looks good and adjust your organization if needed.
