For example, you might have some wood furniture that you will be storing for a long time. It might be smart to add some wood preserver oil to that furniture. Also, depending on the type of storage unit you have rent, climate control or non-climate control, be sure to plan how you will store your electronics if you have any.
As you start packing up your items, remember that these items will most likely shift during the move to the storage facility, and then again when you take them out of the storage facility. Be sure to tape those boxes securely so they won't break apart. Also as you're packing your items use plenty of bubble wrap, packing paper, and blankets.
When you get to your storage facility take a moment to look at the space you're working with and the items you need to store. It's almost like a game of Tetris. As you start moving your items into your storage unit, place the heavier and bulky items towards the bottom and the rear of the unit. While packing your unit, try your best to fit things as close as you can to one another in order to maximize your space. Keep in mind, as you move your items in, it is often smart to leave a pathway along the unit in order to grant future access to items in the back of the storage unit. This will help in case you ever need one item in the back of the unit later. Also, if you have your items label make sure to keep those labels facing out toward the door or the isle.
Finally, when you get everything packed in your storage unit, place a strong, secure lock on the door. We usually recommend disc locks. They prevent bolt cutters from getting around the lock bar, which provides your unit with more security.
Good luck and happy storing!
