Humidity can cause damage to items kept in a self-storage unit, particularly when the weather is hot and muggy. If you are considering moving your personal items into a self-storage unit, you may want to plan ahead for how to prevent humidity from causing damage and mold growth. Here are a few strategies you can use to combat humid conditions in your storage space.

Ensure Your Items Are Dry

Items that are already wet or damp can cause issues in your storage space, even if you have humidity controls put in place. Be sure to completely dry all pool toys, camping equipment, and other items that might normally be exposed to wet conditions before placing them into storage. If you've had your items stored in a basement or cellar previously, consider removing all of the items from the boxes they were stored in, and air them out before packing them away again. Basements and cellars can be damp places, and that means your items may have become moist or damp over time.

Install A Humidity Gauge

Installing a humidity gauge in your storage unit can be a great option for controlling humidity. These gauges will let you know when the humidity is higher, so you can take extra steps to protect your items. You can choose traditional gauges or electronics ones, and they can be hung from a shelf or beam in the storage space. Consider checking in on your unit regularly to assess the humidity, and make an extra trip after a severe storm.

Line The Floors And Walls

You can create a barrier against vapor in your storage unit by lining the floors and walls. Vapor barrier sheeting is ideal for this project, and it can be found at your local hardware store. This type of sheeting is also known as crawl space lining, as it is typically used to keep moisture and humidity out of crawl spaces. Simply roll out the sheeting and tape it in place to prevent making any permanent changes to the unit. If you can't find this type of sheeting, you can also line the walls and floors with cardboard to help absorb moisture. The cardboard, however, will need to be replaced once it has become damp.

Use Cedar

Cedarwood has a host of uses in storage units. It can repel certain insects, and it can also prevent unpleasant odors from overtaking your unit. Perhaps most importantly, it can also be used to absorb moisture. You can use cedar chips in your unit to provide all three benefits, and you can even build custom shelving units made out of cedar to organize your items. Be sure that any cedar you use for building shelves isn't coated or otherwise finished, as the coating and finish can impact the moisture-absorbing properties. 

Ask your storage facility if it offers climate-controlled units, as this can be another way to fight moisture and humidity. Climate-controlled units can sometimes come with humidity control as well as temperature control to protect your items.
