How to Properly Keep Your Storage Unit Dry

Renting a storage unit can be a great solution for storing your belongings when you don’t have enough space at home. However, one common concern when using storage units is keeping your items dry and protected from moisture damage. To ensure your belongings stay in their best condition, here are some essential tips on how to properly keep your storage unit dry.

1. Choose the Right Storage Unit

When renting a storage unit, it is crucial to select the right one that will help minimize the risk of moisture damage. Look for units with climate control features such as temperature and humidity regulation. These units are specially designed to maintain a consistent environment, reducing the chances of moisture-related issues. Climate-controlled units are particularly useful for storing sensitive items like furniture, electronics, and artwork.

2. Use Moisture Absorbers

Moisture absorbers, such as silica gel packets or desiccant bags, are an effective way to keep your storage unit dry. These small pouches contain absorbent materials that can soak up excess moisture in the air. Place them strategically throughout your storage unit, especially around items that are more susceptible to moisture damage. Remember to regularly check and replace the moisture absorbers to maintain their effectiveness.

3. Monitor Humidity Levels

Monitoring the humidity levels in your storage unit is crucial for preventing moisture-related problems. Investing in a hygrometer, a device that measures relative humidity, can help you keep track of the moisture levels. The ideal humidity range for a storage unit is around 30% to 50%. If the humidity exceeds this range, it’s advisable to address the issue promptly by using dehumidifiers or humidity control systems.

4. Use Plastic Sheets and Covers

To provide an extra layer of protection against moisture, consider covering your items with plastic sheets or covers. Plastic is impermeable to water, helping to shield your belongings from any potential leaks or condensation. Be sure to wrap items individually and seal them tightly to prevent moisture from entering. Additionally, using plastic bins instead of cardboard boxes can further protect your items from moisture damage.

5. Elevate Your Items

One effective strategy for keeping your belongings dry is to elevate them off the ground. Moisture can seep through concrete floors, potentially causing water damage to your items. To prevent this, use pallets or shelving units to elevate your items. This will help create an air gap between your belongings and the floor, reducing the chances of moisture damage.

6. Maintain Proper Ventilation

Proper ventilation is crucial in preventing moisture buildup in your storage unit. Ensure that air can circulate freely by leaving enough space between items and not packing your unit too tightly. Consider using fans or dehumidifiers to improve airflow and reduce humidity.

7. Regularly Inspect and Maintain

Regular inspections are essential for identifying any signs of moisture or water damage in your storage unit. Make it a habit to check your unit periodically, focusing on walls, ceilings, corners, and floors for any signs of moisture, mold, or leaks. If you notice any issues, report them to the storage facility management immediately. Additionally, perform routine maintenance on your unit, such as sealing cracks or gaps, to prevent moisture intrusion.

8. Choose a Dry Season for Storage

If possible, consider renting a storage unit during a drier season. Avoiding the rainy or humid seasons can significantly minimize the risk of moisture-related issues. However, keep in mind that even during dry periods, it is still essential to follow the above tips to ensure your items remain protected.


Keeping your storage unit dry is crucial for preserving the condition of your belongings. By choosing the right storage unit, using moisture absorbers, monitoring humidity levels, using plastic covers, elevating your items, maintaining proper ventilation, regularly inspecting and maintaining, and choosing a dry season, you can minimize the risk of moisture damage. Always remember to prioritize the protection of your items and take the necessary precautions to keep them safe and dry.
