MM slash DD slash YYYY

When you store your things with PortaBox, you become part of our family tradition of quality and commitment for over 100 years.

24-Hour Monitoring

Our locally owned and operated warehouses are equipped with security and fire protection systems to ensure maximum protection for your possessions.

Safer than Mini-Storage

The general public is not allowed into the warehouse so your belongings will not be disturbed or vandalized by neighboring units as is possible at Mini-Storage facilities. Only the individuals you authorize using your unique password and photo ID are allowed access to your containers.

Private Access Area

An Access Area is set aside for you so you can securely and conveniently access your containers.
