Facility Amenities


If you’re here, chances are you have more things than you have space for. Whether you want to reserve a self-storage unit for years with Castle Storage or you have never rented a unit before, we’re here to work with you on anything you need during the entire process.

You may also have a few questions in your mind right now. For instance, is the facility equipped with an up-to-date security system? When self-storage renters call, do they talk to knowledgeable managers who are actually on-site? The answer is yes to both of these questions.

Also, if life was simple, everything would happen the right way at the right time. Since it's not, we have an after-hours emergency line - so that any time you run into problems or have questions that can’t wait until business hours, our team is right here for you.
