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.
We are currenty going through a system update please call for unit availability

I have been a customer for 15 years and I love the staff as well as my unit knowing my stuff is protected. I feel like they are my family in Iowa lol.

I have had a unit with them for many years now. It was easy to get and the staff have all been friendly, professional, knowledgeable and very accommodating. When I no longer needed a large unit, it was a simple process to get into a smaller one. Since I am not currently residing in Waterloo, so being able to pay online saves me a lot of hassle. I have just recently closed out my unit here due to moving cross country, and that process was absolutely easy as well. I appreciate what they have done over the years.

I came from out of town to help family, and the staff in the office was really helpful about directions and procedures that would apply to my situation. She took plenty of time to answer all of my questions. The storage unit was clean and the area felt safe and secure. I would recommend this facility!
