Once storage stretches past a couple of months, time, temperature, and humidity become the real risk, not handling. A unit that works fine for a three-week gap between closings is a different situation entirely across a Minnesota winter and the summer that follows. Daymakers Moving & Storage runs climate-controlled storage alongside its moving work, and Bloomington, MN moving company crews prepare a long-term load differently from the start, since almost nobody opens the unit as soon as they originally planned to. Deciding the likely duration honestly before anything goes in changes nearly every decision that follows.
What a longer stay changes actually
Short-term storage is a logistics problem. You are holding a household for a few weeks, access matters more than anything, and the main risk is not being able to reach the box you need. The prep is light because nothing has time to go wrong.
Long-term storage is a preservation problem instead. Months of seasonal cycling work on materials in ways a few weeks never will; adhesives soften and reset, fabrics take on whatever is in the surrounding air, and anything organic that went in unnoticed has time to become a real issue. The load also gets packed for stability rather than for access, since you are far more likely to need the whole unit emptied at once than to need one item from the middle of it.
Why climate control decides the outcome here
Minnesota puts storage through a genuine range. A non-conditioned unit follows the outside temperature, which means deep cold for months followed by heat and humidity, and it is the swing between them rather than either extreme that causes the damage. Materials expand and contract repeatedly, and wood joints, veneers, instruments, electronics, and anything with adhesive in it are the first to show it.
Humidity control matters as much as temperature. Damp air condenses on cold surfaces when conditions shift, and a concrete floor in an unconditioned unit will sweat under anything sitting directly on it. Climate control storage with humidity control, dust suppression, pest management, and around-the-clock security is built into every unit, and that’s the difference between opening a unit after eight months to find what was left versus finding a problem.
Build an inventory you will still understand later
Memory does not survive eight months. Number every box, list the contents against that number in a spreadsheet or a notes app, and photograph the room as each section is loaded so you have a visual record alongside the list. Label boxes on two sides rather than the top, because once the unit is stacked, the tops are the only surfaces you will not be able to see.
Keep a simple map of where things sit in the unit, even a rough sketch showing what is against the back wall and what is near the door. This is also the point to record serial numbers and photograph anything valuable, which is what your insurer will ask for if you ever need to make a claim. Check whether your policy covers goods in storage at all, since many do not, or cap it far below what a full household is worth.
Worth doing before the unit is sealed
- Number, list and photograph every box as it is packed
- Record serial numbers and condition photos for electronics and valuables
- Note which items you may need early and keep them nearest the door
- Confirm with your insurer whether stored goods are covered and to what limit
- Set a calendar reminder to check the unit and review the lease term

What should not go into long-term storage?
Anything perishable, flammable, or pressurized is out, and most facilities prohibit it outright. Food, opened liquids, paint, fuel, propane, aerosols, and cleaning chemicals all belong somewhere else, and the food rule is stricter than people expect, since a forgotten pantry box is how a pest problem starts in a building that houses other people’s belongings.
Some items are permitted but still unwise. Personal documents, passports, jewelry, medication, and irreplaceable photographs should stay with you rather than sitting in a unit you may not visit for months. Batteries should come out of anything that holds them, since a leaking cell inside a remote or a toy will ruin whatever it is sitting in. Plants do not survive, and candles will not keep their shape through a warm spell.
How the load gets built for months
Weight goes low and to the back, with case goods upright, mattresses flat where the unit allows it, and everything raised off the concrete on pallets or boards. Sofas and mattresses get breathable covers rather than sealed plastic, since plastic traps whatever moisture was present when the piece was wrapped and holds it there for the duration. Boxes go in sturdiest first with nothing crushing the layer beneath it, because cardboard that holds for three weeks will fail under the same load after six months.
Air needs somewhere to go. A gap along the walls and a channel through the middle keeps the unit from becoming one sealed mass, and it also leaves you a path in when you do visit. When the same crew handles both the move and the storage, the load can be built in the right order from the truck rather than restacked later, which our post on what full-service moving and storage covers explains in more detail.
Check in, and plan the exit before you need it
Visit once a quarter if you can. A fifteen-minute look tells you whether anything has shifted, whether cardboard is holding, and whether the seasonal change has left any sign on the surfaces you can reach. Rotate a mattress to a different edge while you are there and open a cabinet or two to move some air through them.
Book the move out earlier than feels necessary, since unloading a full household from storage into a home takes a crew and a truck, and the same calendar pressure that fills moving season fills storage retrievals along with it. What to handle thirty days before a move works just as well running in reverse.
