Try to use boxes that are a uniform size, they’re easier to stack
Store your boxes by heaviest & fullest to Lightest & Needed first then start to stack. Maximizing your space by stacking from the back of the unit, making your way to the front. Be sure you stack safely.
Leave small walkways between the boxes and furniture in your storage unit so you can easily get to the items you want without having to move anything around or re-stack boxes.
Stack the heavy boxes on the bottom and the light ones on top. If you’re storing a lot of boxes in your unit, make sure to fill them to the top, even if it’s just with padding or newspapers. Boxes that are only half full tend to collapse when stacking.
For your own safety pack your storage unit so that your most valuable items are at the back.
Start by placing a dust sheet on the floor to protect your goods. To protect your furniture and your appliances from weathering leave a space between your stuff and the unit’s wall allows for air to circulate within the unit. Laying plastic sheeting , old material or fabric on the floor and stacking boxes on top of wooden pallets can prevent condensation damage and protect them from dust.
If you’re storing a refrigerator in your unit leave the door ajar. This will prevent mold from growing inside.
Under no circumstances should you keep anything flammable or combustible in your storage building. This means no gasoline, oil, cleaning fluids or paint thinner. If you’re storing any machinery that runs on gas, drain the tank before you store it.
Store sofas and mattress on end. Stack chairs pad to pad so you may use for stacking boxes.
