Storage units are a convenient way to create extra space, but some items should never be stored away. At Winchendon Self Storage, we want to help you keep your belongings safe and protected.

1. Food & Perishables

Food can spoil, create odors, and attract pests. Avoid storing perishable foods or anything that could invite rodents and insects.

2. Flammable or Hazardous Materials

Gasoline, propane, fireworks, paint thinner, and other hazardous or combustible materials are generally prohibited and can create serious safety risks.

3. Valuables & Irreplaceable Items

Cash, jewelry, passports, important documents, and irreplaceable sentimental items are better kept somewhere secure and accessible. If you couldn't replace it, think twice before storing it.

4. Wet or Damp Belongings

Moisture can lead to mold, mildew, and permanent damage. Always make sure furniture, clothing, mattresses, and other belongings are completely clean and dry before storing them.
