Self Storage in Waterloo, IA
Some self-storage renters have no problem fitting their schedules around business hours, but for many others, 24-hour access provides a lot of benefits. RV owners, for example, are able to hit the road early any day of the week and return late after a nice weekend trip. But Castle Storage offers plenty more useful amenities, such as top security. Only authorized renters are allowed to use their own code to enter the property. What’s more, the area is kept safe through a variety of security cameras.
We’re confident that even if you are planning to have your possessions here for a long minute, you will have no issues because we always take good care of our customers. Whether you are making space in your home or planning to relocate, we’re here to answer any of your questions. And no worries if you have never rented a unit, either - we will gladly help you select the right fit for your self-storage needs. Call us today or visit us during office hours!
