We were extremely pleased with Guardian, the security and cleanliness of the facility and the friendly professionalism of the staff. It was also a benefit having the opportunity to utilize their truck free of charge when we moved in, and after the year, at a very reasonable rate, to move to the home we bought.

I stored at Guardian in Superior, CO for 5 years. They were always very helpful, always friendly and easy to reach on the phone. Guardian sells supplies necessary for moving which is very convenient when you don't think of rope as something you may need during your move, they have rope! Security is good. If you forget to lock your unit or do it incorrectly, you will be called and your storage unit will be secured again. The grounds and interior storage units are kept immaculately. A bottle of water is handed over with a smile after loading and moving. I had a great experience using Guardian!

Melissa was very helpful. We were set up with a storage locker quickly and were able to start moving items in the same day. The lockers were very clean, the place felt very secure, and we had no problems entering or leaving the facility. Carts were available for loading heavy items from your vehicle to locker. Price was very competitive. Highly recommend this facility.

This business truly deserves 5 stars! From the start employees were very professional and courteous, but they went above and beyond to help when my moving crew failed to show up and when my phone was missing in the back of the moving truck.A. provided water along with encouraging words and assistance with finding my phone. She also helped me to get the ramp to the truck back in place. I so appreciated this help because I have physical limitations for certain things.M. offered a way that I could save some money which made me feel the company has integrity and is willing to provide service that truly meets customer's needs.I highly recommend Guardian Storage Superior.
