There is a certain level of strategy that goes into storing your items efficiently. Organization is key, and there are quite a few approaches to using your space like a professional. First, gather all the materials you think you will need; tape, markers, packing materials, and towels. Then prepare your unit by placing a protective cover or tarp on the floor under your goods. If your location has a history of heavy rains or flooding, consider placing your storage items on boards or pallets to protect them from water. Any concrete floor can become cold and produce condensation causing items to become damp.
