Possible Culprits for Your Storage Unit Smelling Funky 

Having a storage unit is incredibly convenient, but sometimes there can be unpleasant odors that arise from it. If you are experiencing an unpleasant smell in your storage unit, it’s important to identify the source and take action to eliminate it. Here are seven possible culprits for your storage unit smelling funky:

Mold and Mildew:

This is one of the most common culprits for a smelly storage unit. Mold and mildew thrive in moist environments, so if there is any moisture or humidity in your storage unit, it can lead to mold growth. This can cause an unpleasant musty smell that can be difficult to get rid of. To prevent this from happening, make sure to keep your storage unit dry and well ventilated.


Another common cause of a funky smell in storage units are pests, such as rodents or insects. These critters may enter your unit if there are any cracks or openings that they can squeeze through. Once inside, they can leave droppings and urine which can lead to an unpleasant odor. To prevent this, make sure to seal any openings in your storage unit and regularly inspect for signs of pests.

Spilled Items:

If you have stored liquids or food items in your unit, there is a possibility that they may have spilled and caused an unpleasant smell. If this is the case, be sure to clean up the spill thoroughly and consider storing these items in sealed containers to prevent future spills.

Old and Musty Furniture:

If you have stored old furniture in your unit, it may be the culprit for the funky smell. Old and musty furniture can emit a strong odor that can permeate through your storage unit. To avoid this, consider thoroughly cleaning any furniture before storing it or opt to store it in a climate-controlled unit.


If you have stored any chemicals in your unit, they may be the cause of the unpleasant smell. Some chemicals can emit fumes that can linger and create an odor. If possible, avoid storing chemicals in your storage unit or make sure they are properly sealed to prevent leaks.

Stagnant Air:

If you haven’t accessed your storage unit for a while, the air inside may have become stagnant and developed an unpleasant smell. To prevent this, make sure to visit your unit regularly and open it up for some fresh air.

Human Error:

Lastly, sometimes the culprit for a funky smelling storage unit can simply be human error. If you forgot to clean out perishable items before storing them or accidentally spilled something, it can lead to unpleasant odors. To prevent this, always double check the contents of your unit before closing it up and consider using air fresheners or deodorizers to keep it smelling fresh.

By identifying these possible culprits for a smelly storage unit, you can take the necessary steps to eliminate the odor and ensure that your items remain in good condition. Regular maintenance and proper storage techniques can go a long way in preventing unpleasant smells in your storage unit. Remember, a little effort now can save you from dealing with a funky smelling unit later on! So, make sure to keep these culprits in mind and take proactive measures to keep your storage unit smelling fresh and clean.
