If you've got an unfinished basement, you're probably using it for one reason: storage. However, keeping any prized possessions or little-used items in a damp, dark, temperately fluctuating dungeon might not be the piece-of-cake solution you think it is. In fact, keeping all that stuff in your home's lowest level can irrevocably tarnish your valuables and—in some cases—even put your home at risk of major disaster. So, read on to learn all about the items you should never store in your basement.

Your beloved family photo albums won't be long for this world if you're keeping them in the basement. "Your photos will not survive humid environments and over time, even dryness will make them brittle," says Karin Socci, a Master Certified KonMari Consultant and owner of The Serene Home. "It's far better to transfer the media to cloud-based formats so that you will have images that are easy to share."


financial paperwork things you shouldn't store in your basement

The deed to your house, your car title, and your tax return should be stored somewhere safe—but your basement isn't that place. "Documents should not be kept in either the attic or the basement," says professional organizer Susan Santoro, founder of organizing website Organized31. Instead, keep them in a home office (or desk).

Family Heirlooms

If you've got family heirlooms you're hoping to pass on, it's never a safe bet to store them in the basement. "Your basement may have never flooded up until now, but that's no guarantee it will never happen," says Socci. "A pipe could burst or unusual weather activity could cause unexpected flooding. If you have ever witnessed the aftereffects of a flooded basement, you know that water and mildew spare nothing."

Humid environments, like basements, are prime real estate for mold and mildew, meaning you won't want to store bedding down there unless it's well-sealed. After all, you probably don't want to press your face and body against something that's been invaded by potentially-harmful mold spores, which can cause everything from headaches to respiratory distress.


children with tons of toys, things you shouldn't store in your basement

Your children's or grandchildren's beloved toys have no business in your basement. Firstly, there's the ever-present risk of mold and mildew. Secondly, basement storage means you're risking water damage courtesy of burst pipes. Thirdly, the brutal cold and intense heat you may find in a basement without an HVAC system can also cause the batteries inside electronic toys to burst. And lastly, two words: pest damage.

Putting your bike in the basement may keep it out of the way, but it can also make it unusable when you need it. The temperature fluctuations in your basement can cause your tires to lose pressure, so it's best to store it in a more climate-controlled space when possible.

Pet Food

Dog Eating Food From a Bowl, things you shouldn't store in your basement

If you're storing pet food in your basement, you're asking for pests to make it their home. Bags of dog or cat food can easily be opened by mice and the humidity in your basement may even shorten the shelf life of bags of kibble.

Canned Food

Those cans may not need to be refrigerated, but that doesn't mean they don't need a climate-controlled environment. According to the United States Department of Agriculture, cans that accidentally freeze in a basement have the potential to cause health problems for those consuming them, and cans that have been frozen but have subsequently thawed outside of a refrigerator are no longer safe for consumption.

Brass and Woodwind Instruments

While you may want your kids' instruments to stop cluttering up the living room, the basement isn't the right place to store them. "The basement is the worst place to store an instrument," says Lucas Workman, a brass repair technician at Siegfried's Call, a New York-based horn outfitter. "The big enemy when it comes to storing instruments is humidity. That moisture just stays and it can even affect the finish of the instrument. The residual water in them can grow into mold. The pads and the fabric in woodwinds can start to crack."


bottle of wine things you shouldn't store in your basement

If you want to keep your wine delicious and drinkable, your basement—with its fluctuating temperatures—isn't the place to do so. Temperature changes and humidity can cause your wine to change dramatically in terms of both color and flavor, so it's better to keep it in a drier, more consistently cool part of the house.

If your basement is home to your furnace, it's probably a good idea to keep spare gas cans somewhere else. As a general rule, anything combustible, like gasoline, should be given wide berth from potential fire hazards like furnaces.

Cat Litter

Surprisingly enough, cat litter is yet another product you're better off keeping out of the basement. In addition to potentially clumping when it's exposed to moisture like the humidity in your basement, if you're actually letting your pet use your basement as a bathroom, the ammonia in their urine becomes potentially combustible when stored too close to your furnace.

That pricey cord of firewood won't do much good to keep you warm if it's kept in your basement. In addition to potentially attracting pests, the humidity in your basement can make that wood damp—and less than ideal for starting a fire.

Propane Tanks

The temperature fluctuations in your basement make it a poor choice for storing propane. Propane tanks can explode if left in extreme heat, so if your basement gets unseasonably warm, they could potentially explode. In one notable 1983 incident, in Buffalo, New York, six people—five of them firefighters—were killed and 70 more were injured from a fire and explosion caused by illegally stored propane.


dvd player, things you shouldn't store in your basement

If you're storing your DVD collection in the basement, let's hope you've got streaming subscriptions, because those discs won't last long. The temperature fluctuation in your basement can easily cause those DVDs to warp and become unplayable.


Vinyl, things you shouldn't store in your basement

Can you store your records in your basement? Sure—if you don't care if you can hear the songs when you're ready to play them. Not only are their cardboard sleeves a picnic for pests, that vinyl can warp and crack in your basement's extreme temperatures.
