Climate-controlled storage in Waunakee
27 of our 184 Waunakee units are inside a climate-controlled building, in 5 × 10, 8 × 9, 10 × 10 and 8 × 18 sizes. The building has an indoor unloading zone, a staging area and wide hallways, so you load and unload out of the weather.
Wisconsin swings from below zero in January to humid 90-degree days in July. That cycle is hard on wood furniture, mattresses, electronics, photographs, documents, musical instruments and anything made of leather or fabric. 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. Tools, outdoor gear, vehicles and most boxed household goods do fine in a standard drive-up unit.
Climate-controlled units are only at this location. Our Blue Mounds / Mount Horeb facility is drive-up and outside storage only.
