Shelf Self Storage: The Mistakes That Cost You

Find Out More →

If you've ever stood in front of a self storage unit thinking 'I've definitely rented more space than I need', you're not alone. Over the past few years, I've watched a lot of Shelf residents sign up for storage—some for house moves, others for overflow from those old mill conversion lofts round the valley—and the same mistakes keep coming up. The good news is they're easy to spot once you know what to look for.

Overestimating how much space you actually need

This is the biggest one. People look at their pile of boxes or furniture, make a rough guess, and rent a unit that's 50% bigger than necessary. Then they're paying for empty air month after month.

The reason this happens is simple: we're bad at visualising volume. That stack of boxes doesn't feel like much until you start loading them in, and a 50 square foot unit looks cavernous when it's empty. By the time you realise you've overpaid, you're already locked in for three months.

Before booking anything, actually measure what you're storing—not guess. Measure your furniture dimensions, count your boxes, stack them up in your hallway. Then add maybe 10% for breathing room. If you're storing furniture from a two-bed house, you're probably looking at 75-100 sq ft, not 150. If it's just seasonal decorations or a few boxes, you need far less.

Not thinking about access and what you'll actually need

You rent a storage unit thinking you'll just dump everything in there and leave it untouched for six months. Then life happens—you need that one box of winter clothes in July, or you want to grab the drill you know you packed somewhere.

If you haven't thought through how often you'll need access and what's actually in there, you'll end up with a unit that's packed so tightly you can't reach anything without moving half the contents. That's frustrating and it defeats the point of storage in the first place.

When you're planning what to store, think about frequency. Items you might need within the next couple of months should go near the front. Anything you won't touch—off-season clothes, old paperwork you're keeping for insurance, that box of vinyl records—can go deeper in. Label everything clearly so you're not tearing open boxes hunting for your passport.

Forgetting about moisture and protection

Shelf sits in the Colden Valley catchment area, which means we get our fair share of damp. If you've lived here long enough, you know how moisture can creep into things—basements, garages, sheds. Storage units aren't immune to this, especially if you're not thinking ahead.

People often store items without any real protection and then get surprised when boxes start to weaken or fabric gets musty. Books, photographs, vintage furniture—these things don't forgive dampness. Neither does electronics.

Use plastic boxes instead of cardboard where you can, especially for anything precious or irreplaceable. Add a small dehumidifier if you're storing items that matter. Wrap furniture in blankets or moving pads to protect it from dust and moisture. It costs a bit more upfront, but it's worth it when you open that box six months later and everything's in the same condition you left it. Find out more on protecting your items during storage.

Not asking about the actual cost before you commit

You get a quote, it sounds reasonable, and you sign up. Then the invoice arrives and it's higher than expected—insurance you didn't realise you needed, access fees, or a rate that goes up after the first month.

The confusion happens because people don't ask the right questions upfront. They hear a price per month and assume that's what they'll pay, without checking what else is included or excluded. Some facilities charge for vehicle access, some have different rates depending on unit size categories, and some have promotional rates that change after a set period.

Before you book, ask exactly what's included in the quote and what isn't. Does it include insurance? Are there access fees? What happens to your rate after the first month or year? Get it in writing. This article explains what actually drives the cost of self storage, so you can compare properly.
