Alright, friend. Let’s have a real talk about summer storage. I’ve been running 3D Self Storage for over a decade now, and every single summer, I see the same heartbreaking mistakes. Good people, with perfectly good stuff, who end up with a warped, mildewy, bug-infested mess because they didn’t know how to fight back against the summer swelter.

I’m not here to scare you. I’m here to give you the inside track. The stuff I tell my own family when they rent a unit. This isn’t from a corporate handbook; it’s from years of hauling ruined couches to the dumpster and wishing I could have warned the owners. Let’s make sure that doesn’t happen to you.

The Silent Killer Isn’t the Heat—It’s the Sweat

You’re worried about things melting. I get it. But let me tell you, the heat is just a loud distraction. The real ninja here is the humidity. That thick, muggy, soupy air that hangs around from June to August? That’s what ruins lives.

I had a customer, a lovely woman who stored her mother’s beautiful solid oak dining set. It was flawless when it went in. By Labor Day, the wood had swollen so much the drawers wouldn’t close, and a dark shadow of mildew was growing up the legs. The heat didn’t do that. The humidity did. It’s a brutal lesson to learn.

Your absolute, number-one, non-negotiable weapon?

A climate-controlled unit. Look, I own the place, and I’ll be the first to tell you—if you care about it, it belongs in climate control. It’s not just air conditioning. It’s a dehumidifier. It keeps the environment steady and dry, like a perfect spring day, all season long. It’s the difference between storing your wedding photos in your closet and storing them in a steamy bathroom. For your wood furniture, your electronics, your family photos, your important documents—it is quite literally the only choice.

At 3D Self Storage, we walk every new customer through this. It’s the first thing we talk about. We’d rather you have a smaller, climate-controlled unit than a giant standard one full of regret. Trust me on this.

Packing: This is Where You Build Your Fortress

How you pack is everything. This is your hands-on work. This is where you win.

Clean it like you’re expecting a royal inspection

I cannot stress this enough. That single Cheerio stuck under the seat of a kitchen chair? That’s a beacon for pests. The invisible film of soda on a plastic toy? They’ll smell it. Take everything outside, wipe it down with a simple vinegar and water mix, and let it dry completely in the sun. A clean item is an uninteresting item to bugs and rodents. This is your first, best defense.

Cardboard is for groceries, not for storage

Those old Amazon boxes are flimsy, and they absorb moisture like a sponge. Then they transfer that dampness right to your things. And if one gets wet, it collapses and takes the whole stack with it. You want clear, sturdy, plastic bins with locking lids. Every time. They’re stackable, they’re strong, and they create a fantastic seal. Plus, you can see what’s inside without having to play guessing games later. It’s worth the investment.

Label like a crazy person

“Misc. Kitchen” is a useless label. Your future self will curse your name. Be ridiculously, obnoxiously specific. “Winter Coats – John’s Parka, Sarah’s Peacoat” or “Holiday Decor – Glass Ornaments, FRAGILE.” When you need that one specific thing on a busy December night, you will send me a mental thank-you note.

Loading It In: It’s Strategy, Not Muscle

Don’t just chuck boxes in until the door won’t close. Think like a chess master.

Give your stuff some breathing room

Never, ever push your items directly against the wall. Concrete walls can “sweat” from the temperature difference between the inside and outside. Leave a good 3-4 inch gap around the entire perimeter of your unit. This allows for air circulation and stops moisture from wicking into your boxes and furniture. Your stuff needs personal space.

Build a pyramid, not a pile

The heaviest, sturdiest items go on the bottom, pushed toward the back. Think: washing machine, tool chests, solid wood dressers. Lighter boxes go on top. Plan it out. Create a center aisle so you can actually walk to the back of the unit without having to perform an archaeological dig. You will need to get to something eventually. Make it easy on yourself.

A couple of cheap pro-tricks

Toss a handful of silica gel packets (the “do not eat” kind from new shoes) into your bins of clothes or documents. For the whole unit, pick up a standalone moisture absorber like DampRid from the store. It passively pulls gallons of water right out of the air. It’s a fantastic backup soldier in your fight against humidity.

The “Oh Heck No” List: What to NEVER Store

Some things have no business being in a storage unit, period. Summer just makes the consequences worse.

• Anything that can explode or become a toxic mess: Gasoline for the lawnmower, propane tanks for the grill, paint thinner, aerosol cans of spray paint. The heat can cause pressure to build up and containers to fail. It’s a serious fire and safety hazard. Just don’t. Find another solution.
• Anything that smells like food: I don’t care if it’s canned goods, unopened bags of dog food, or that expensive bottle of olive oil from your vacation. You are building a five-star resort for pests. They will find a way in. They always do. It will be a disgusting, expensive nightmare to clean up.
• The truly irreplaceable: If it has more sentimental value than monetary value, a standard storage unit is not its home. Your grandmother’s quilt, your child’s baby book, your wedding album. For these priceless items, climate control is the only option. If you can’t afford to put it in climate control, you can’t afford to risk it in storage. Keep it at home.

Look, storing your stuff should make your life easier, not create a catastrophic time capsule of regret for you to open later. A little bit of smart planning and the right investment on the front end will save you money, heartache, and a major headache down the road.
