When the temperatures rise, so do the risks to your stored items. Whether you're stashing away furniture, electronics, seasonal clothing, or anything in between, summer heat and humidity can do real damage. At Bolt Storage, we want to make sure your belongings stay protected and in great shape no matter the weather.

Looking for secure storage this summer? Find a Bolt Storage location near you and rent in minutes online or by phone.

‍

Here are our top tips to help you store smarter this summer:

1. Choose Climate-Controlled Storage When Possible

If you’re storing sensitive items like electronics, wooden furniture, important documents, or anything that could warp, melt, or mold, a climate-controlled unit is a must. It helps keep the temperature and humidity consistent, which protects against extreme heat and moisture.

Tip: Look for our climate-controlled units at select Bolt Storage locations. They’re a smart investment, especially for long-term storage during hot months.

2. Don’t Store Items That Can Be Damaged by Heat

Some items just aren’t summer-storage friendly. Avoid putting the following in your storage unit during peak heat:

  • Candles (they melt)
  • Vinyl records (they warp)
  • Aerosol cans (they can explode)
  • Perishables or food (they attract pests)

If in doubt, leave it out—or ask our team if your item is safe to store. Explore how Bolt Storage protects your items with top-notch security in this post all about our safety features.

3. Use Plastic Bins Instead of Cardboard Boxes

Humidity and heat can break down cardboard quickly, leaving your items vulnerable. Clear plastic storage bins with tight-fitting lids help protect your belongings from moisture, pests, and dust.

Bonus: Clear bins make it easier to find what you need when it’s time to unpack.

4. Prep Appliances & Electronics Carefully

If you're storing appliances or electronics, clean and dry them thoroughly first. Moisture left behind can lead to mildew or corrosion. Remove batteries (they can leak), and store cords neatly in labeled bags.

For fridges or washers, leave the doors slightly open to prevent mold and odors.

5. Elevate Items Off the Floor

Even in the best storage units, summer storms or humidity can cause condensation. Use pallets or shelving to keep boxes and furniture slightly elevated and promote airflow.

6. Cover with Breathable Fabrics

Plastic wrap can trap moisture. Instead, use cotton sheets or furniture covers that allow air circulation while protecting from dust and scratches.

7. Label Everything Clearly

Summer storage is often temporary (think: summer break, seasonal cleanouts, or moves). Make your life easier by labeling each bin or box with the contents and room it belongs to. This will save you time when unpacking later.
