Items to Avoid Storing in Your Shed

Getting organized is such a great feeling and sheds are a perfect way to do that. A shed is great for overflow storage when you’ve run out of space in your closet, attic or garage. Although there are many items you can store in a shed, there are also many items you shouldn’t.

Items can be easily damaged or ruined in portable buildings that are not insulated or climate controlled as a result of temperature fluctuation and moisture. Items can also be damaged by unwanted guests such as rodents and bugs.
