The basement is a common place for many homeowners to store away unused items.  From holiday decorations and old furniture to gadgets and keepsakes, it can often become the dumping ground for our clutter. However, you'll be surprised to learn there are just some things you should never store in the basement. In fact, incorrect storage will probably do more damage than good to your precious belongings. 

Much like the reasons for things you should never store in the attic, basements are prone to fluctuating temperatures, and humidity throughout the year. As a result, damp conditions in the basement could destroy any valuable items stored there. 

So, before you tackle the task of decluttering your home, here are common things you should never store in the basement. Just be sure not to make any of these decluttering mistakes while doing so! 

Plus, here are 7 things you should never store in your garage, and 7 things  you should never store in the shed — but probably are!

1. Old family photos or keepsakes

Whether you have family collectibles, documents or precious photo albums that you want to preserve, never store these in the basement. Big changes in humidity and temperature may ruin the prints or make photos stick together. If you want to preserve those vintage photographs or prints, be sure to store them in a waterproof box/container on a shelf in a dry area. Once moisture gets to them, these will be permanently damaged. So don’t risk it! 

2. Books

Similarly, if you want to hold on to your classic books, or simply lack bookshelf space for your growing collection, avoid storing books in the basement. Not only can the pages become discolored from traces of humidity, but can also attract silverfish.  

Silverfish are tiny (and fast-moving) insects that thrive in dark, damp environments like basements and attics. They live on starchy substances, such as the glue that binds books, and are capable of destroying books, wallpaper, carpets and clothes with their droppings. In which case, you’ll definitely need to know how to get rid of silverfish fast. The best way to store books is in a cool, dry place, away from sources of heat and moisture.  

3. Toys

While the basement may seem like the obvious place to dump children’s toys — this is not a good idea. Plush toys, fabric-made dolls or any other stuffed toy are likely to attract dust mites, other types of  insects, or even mice should they happen to find their way into the basement. 

The same applies if you want to store any delicate or natural fabrics, which could attract moths. If you don’t want your favorite toys or winter sweaters ruined, make sure these are secured in airtight boxes/containers, and in a dry, cool place other than the basement.

4. Wooden furniture

Whether you’re storing excess chairs or tables, or perhaps you want to restore/update antiques, wooden furniture should not be stored in the basement. Any moisture or condensation from your basement can cause wood furniture to crack or warp, especially if the wood hasn’t been treated. What’s more, damp conditions can lead to rotting wood, which could ruin your vintage pieces of furniture.  

5. Rugs or carpet

If you have rolled-up rugs or leftover carpet, avoid storing these in the basement. Not only can the humidity and moisture form mold spores or mildew within the fabric, but can also become a warm haven for mice and other pests! 

Plus, don’t consider laying them out flat on the floor either, as moisture will seep through underneath. The best method is to wrap the rug in a protective plastic or sheet, before storing upright, and off the ground in a well-ventilated area. 

6. Electronics

We’re always upgrading our electronic devices, and often stash old laptops, computers, games consoles or any other gadget into storage. However, storing electronics in a humid basement could cause them to overheat, or stop working altogether. 

Instead, store old electrical items in a cool environment that is well-ventilated. Or better still, you can recycle, donate or sell old computers and devices. After all, what’s the likelihood that you’ll end up using them again?

7. Food supplies

While it’s quite common for households to stockpile on pantry supplies, never store them on the basement floor. If not stored correctly, perishables can easily spoil from humid temperatures during warmer months. What’s more, the heat will essentially cook your tinned foods before you’re ready to actually eat them!

It’s best to always store tinned food, drink and other dried items in airtight containers or plastic bags, in a cool, dry area. Keep boxes off the ground by placing them on shelves or even pallets. This is also handy in the case of potential flooding, to avoid your food supplies from being damaged. More importantly, you don’t want to provide the perfect feast for mice or any other pests in the basement.
