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.

Thank you Melissa and your team for outstanding service over the 18 months that we stored our furniture in your facility. We were out of the country and you responded promptly to any request, including receiving more furniture that we had purchased and sent to our storage. This service made it possible for us to plan for our big move to France. Thanks again as you went above and beyond what I expected a storage facility to provide.Vidan and Alison Gonthier

We are moving to a new house. With many, many things to do, I was able to reserve, and pay for our unit at 4:30am which was very convenient. A quick stop in the office during business hours finalized things and I went and checked out the unit. It was clean, dry, had an interior light, and definitely ready for us to put our overflow items there for a few months.I created a small amount of office confusion by both requesting a coupon from the web site (which creates a lead that they follow up on by calling you), and reserving on line. The follow up call on the lead was a bit disconcerting because the voice mail made me think my reservation was somehow incomplete.If I were to improve two things, I would install more lighting over each unit to make it easier to see your lock so inserting the key at night was easier. My cell phone flashlight works, but it isn't as convenient as more lighting would be.I also would consider switching to 24/7 access. Right now with 6am - 10pm an interval that I am working I can not get into the facility.

Great location. Very clean. Competitive pricing. Friendly staff.We have used them twice in the past 7 years to store our property as we moved homes. Each time they were helpful in selecting the right size, the right location within their units, and answering any questions we had. The property is very clean both outside and inside their units. We utilized their carts to move items in and out of the buildings. They were well-maintained and always available. We highly recommend Guardian for any of your storage needs!
