We proudly serve residential and business customers from Cornwall, Lancaster, Martintown, and the surrounding communities with affordable, heated self storage services and excellent customer service. Our convenient location in Downtown Cornwall makes us an especially great choice for residents living in Ultra Vista Towers, Adolphus Court Apartments, and Sunset Tower Apartments. We are also just around the corner from Water Street Condos, The Cotton Mill Condos, and the Knox City Center.

Our business customers enjoy the convenience of 24/7 access to their equipment, supplies, and document storage. It doesn't matter what your operating hours are, unlike many self storage facilities with limited access hours, your unit is always available!
