Here are some essential tips for long-term storage:

1. Pack your items carefully: Use sturdy cardboard boxes instead of plastic bags, check for moisture, sell or throw away what you can, make copies of important documents, and wrap fragile and valuable items individually in soft packing paper.
2. Use clear containers: Use sturdy, clear containers to hold your things while they are in the long-term storage unit. Clear bins that have strong sides and a lid are often the best way to store things. That way, you can see into the bins to find out what you packed and how it is arranged.
3. Label your boxes: Clearly label all of your boxes with their contents and the date they were packed.
4. Stack and label boxes correctly: Make sure boxes are stacked and labelled correctly to avoid damage to your belongings.
5. Dismantle bulky furniture: Dismantle bulky furniture to reduce the risk of damage and save space.
6. Keep items off the floor: Keep all moving boxes, containers, and furniture off the floor whenever possible. Improperly storing your items, even for the short term, can result in unnecessary damage.

I hope these tips help you with your long-term storage needs!
