Awesome storage facility just outside of the city. The spaces are clean, dry , and secure. I can drive inside the building to do all of my loading which is great when it rains or in the winter. The customer service is 2nd to none!!

I've been a customer for over 10 years and have upgraded my storage unit twice over that time. Staff is knowledgeable and always proactive on the logistics of moving and storing. I would recommend Castle to anyone needing a convenient, safe and easy-to-navigate storage facility.
