Using a storage unit can make life much easier, whether you are moving home, freeing up space, storing business stock, or keeping seasonal items out of the way. But many people make simple mistakes that can lead to damage, wasted space, stress, and extra cost.
At Big Top Self Storage, we want customers to get the most from their storage space. A little planning goes a long way. Here are ten of the most common mistakes people make when using storage units, and how to avoid them.
Mistake one, choosing the wrong size unit
One of the most common errors is renting a unit that is either too small or far too large. A unit that is too small can become overcrowded and difficult to access. A unit that is too large means you may be paying for space you do not need.
Before moving in, make a list of what you plan to store. Think about furniture, boxes, awkward shapes, and whether you will need room to walk inside the unit. Big Top Self Storage can help you choose the right size, so you only pay for the space that works for you.
Mistake two, packing without a plan
It is easy to throw everything into boxes and hope for the best, especially during a busy move. But poor packing can cause breakages, make items hard to find, and waste valuable space.
Pack by category, label every box clearly, and keep similar items together. Heavier boxes should go at the bottom, lighter ones on top. Try to think ahead about what you may need to access first.
Mistake three, using weak or unsuitable boxes
Old supermarket boxes or damaged cartons may seem like a cheap option, but they often collapse under pressure or become hard to stack safely. This can damage the contents and make the whole unit unstable.
Use strong storage boxes that are designed for stacking. Uniform box sizes also make the unit easier to organise and safer to load.
Mistake four, failing to protect furniture and fragile items
Many people place furniture, mirrors, glassware, and electronics into storage without enough protection. This can lead to scratches, dents, chipped corners, or worse.
Wrap fragile items carefully, cover furniture properly, and use protective materials between stacked goods. Drawers and doors should be secured, and delicate items should never be left exposed.
Mistake five, not labelling boxes
Unlabelled boxes quickly become a problem. What seems obvious on move in day may be impossible to remember a few weeks later. This often leads to people opening multiple boxes just to find one item.
Clear labelling saves time and frustration. Write on more than one side of each box and be specific. Kitchen items, winter clothes, business files, and spare bedding are much more useful labels than misc.
Mistake six, blocking access to important items
People often place everything tightly into the unit without thinking about future access. Then when they need one document, one suitcase, or one seasonal item, they have to unload half the unit.
A better approach is to create a simple layout. Keep the items you may need sooner near the front. Leave a narrow walkway if possible. That small bit of planning makes a big difference later.
Mistake seven, storing items that should not be stored
Not everything belongs in a storage unit. People sometimes try to store perishable food, wet items, or anything that could leak, spoil, or cause damage to surrounding belongings.
Make sure everything is clean, dry, and suitable for storage before moving it in. If you are unsure, Big Top Self Storage can advise on best practice so your unit stays safe and your belongings stay protected.
Mistake eight, forgetting to clean items before storage
Dust, moisture, crumbs, and dirt can all create problems over time. Clothing, furniture, appliances, and kitchenware should be properly cleaned before going into storage.
This is especially important for fridges, washing machines, and anything fabric based. A clean item stored correctly is far more likely to come out in the same condition it went in.
Mistake nine, wasting vertical space
Many customers focus only on floor area and forget how much room they have upwards. This often leads to underused space and a cluttered layout.
Stack safely and make the most of the height of the unit. Use shelving if appropriate, place sturdy boxes at the base, and build upwards carefully. Good organisation can help you fit more into the same space without making the unit chaotic.
Mistake ten, not thinking about insurance and peace of mind
Some people assume their belongings are automatically covered, without checking what protection is in place. It is always worth understanding your insurance position before storing valuable items.
Taking a few minutes to review cover can save major stress later. Peace of mind is a big part of using self storage properly, especially for important personal or business belongings.
