Altitude & Attics—Smart Storage in Denver Homes

In Denver, our homes often come with quirky storage spaces—uninsulated attics, partially finished basements, and garages that swing from freezing to scorching. Storing your seasonal items in these areas can work if you plan for the temperature swings and altitude quirks. Here’s how to store your stuff safely and smartly.

Know the Risks

Denver’s dry air and major temperature fluctuations can be tough on certain materials. Heat can warp plastics and crack rubber; cold can damage electronics; and paper, photos, or fabric stored in non-climate-controlled spaces can degrade faster.

Use Airtight, Labeled Bins

Choose clear, hard plastic bins with secure lids to protect from dust, pests, and moisture. Label all sides and keep a seasonal inventory list so you're not hunting next year. If your storage area is particularly dusty, make sure to get bins that are weathertight to keep the elements out.

Elevate Off the Floor

In basements or garages, always keep bins off the concrete floor. Use shelves or pallets to avoid water damage during snowmelt or unexpected leaks.

Avoid Cardboard for Long-Term Storage

Cardboard absorbs moisture and can attract pests—especially in attics or garages. It’s great for moving, but not long-term stashing.

Store Smart by Season

Rotate items out twice a year: spring/summer and fall/winter. Keep snow gear, décor, and camping equipment accessible when you actually need them.

Know What Can Handle Temperature Swings

Clothing, outdoors gear, and gardening supplies can all manage the high highs and the low lows for the most part. Family photos, food, medications, power tool batteries, and sunscreen should all be kept inside in a climate controlled environment.

Final Thoughts:

You don’t need a walk-in attic to make seasonal storage work—you just need a solid system.
