Storage FAQ

Temperature-controlled storage facilities use high-quality HVAC systems, dehumidifiers, and thermostats to maintain a consistent environment. These units typically stay between 55°F and 85°F year-round, helping to protect your items from damage caused by extreme temperatures. This helps minimize the risk of mold, mildew, rust, corrosion, yellowing, warping, and pest infestations.

Renting a unit is easy! You can call or text 608-849-6281, or email jarstorage1@gmail.com between 8:00 AM and 4:30 PM, Monday to Friday.

At JAR Storage, we offer a variety of unit sizes to suit your needs. Please note that availability may vary by location. Check out our Locations Page to find the right location and fit for you.

No! All our units are rented on a month-to-month basis, giving you the flexibility to store short-term or long-term, whatever suits you best.

A 5 x 10 holds the contents of a large closet or a dorm room. A 10 x 10 holds a one-bedroom apartment. A 10 x 20 holds a three-bedroom home or a car. Our 10 x 30 and 10 x 40 units handle a large home, a contractor's equipment, or a boat or camper on its trailer. Our storage unit size guide shows every size we rent, drawn to scale, with what typically fits in each.

If you are storing for more than a season, or storing anything you would not leave in an unheated garage all winter, choose climate control. Wisconsin swings from below zero in January to humid 90-degree days in July, and that cycle is hard on wood furniture, mattresses, electronics, photographs, documents, musical instruments, and anything made of leather or fabric. Our 27 climate-controlled units are at the Waunakee facility. Tools, outdoor equipment, vehicles and most boxed household goods do fine in a standard drive-up unit.

Yes. Our Blue Mounds / Mount Horeb facility has uncovered outside spaces sized 13 x 30 ft and 13 x 40 ft for a boat on its trailer, a travel trailer, a fifth wheel or a camper. Both facilities also have 10 x 40 drive-up units for enclosed storage. See our boat, RV and trailer storage page for what fits, and call ahead in late summer if you want a space for the winter.

Choose Waunakee if you need climate control, want the widest choice of sizes (ten, from 5 x 10 to 10 x 40), or live north of Madison, in DeForest, Middleton, Dane or Lodi. Choose Blue Mounds / Mount Horeb if you need outside space for a boat or camper, or live in Mount Horeb, Barneveld, Verona, Ridgeway or Dodgeville. Both rent month to month with 24/7 access, and the same office answers the phone for both.

The usual rules apply: no gasoline, propane or other fuels outside of a vehicle's tank, no fireworks, explosives, hazardous or flammable chemicals, no perishable food, no plants or animals, and nothing illegal. Vehicles should be drained of excess fuel and in safe condition. If you are not sure about an item, call us before you bring it.

Check with your homeowner's or renter's insurance agent. Many policies extend some coverage to belongings kept off the premises, and your agent can add a rider if yours does not. We recommend insuring anything you could not easily replace.

Yes. All units require a security deposit, which is returned when you move out with a 30-day notice and the unit is left clean and empty.

Soon. Our new dry portable storage units can be delivered to your home, job site or business, or kept at our facility. Call or text 608-849-6281 and we will let you know as soon as they are available.
