“Oh my goodness where do I begin? Ashley was and is Remarkable!! I needed help with a bike issue she was able to resolve this!!! Then I had an issue with my phone.. Well you guessed it Ashley helped resolve that issue also… Storage Masters isn’t just storage.. Customer Service is absolutely Spectacular!!! I highly recommend Storage Masters!!.”
“We are renting two storage units from the St. Charles location. The environment and hospitality is like being at home. Diane who manages this location make everyone feel like family. I can say enough good about this facility. Todd VanHoogstrate.”
“Easy move and Diane the manager was very helpful. We left a storage place that raised our rent by $80.00 after 1 year. To Storage Masters which was a much better deal. Diane helped us get the free truck to move and after moving provided free bottles of water that were really needed..”

“Very friendly service, Diane is the best. Very clean, secure and well lit facility in addition to excellent customer service. Great pricing. Five stars all....”

“I have used this location for several years and love it. The place is impeccably clean and I like the way they put little canisters of chemicals to control....”

“Service was excellent. The units were clean and well maintained. And the manager Diane was extremely kind, courteous and caring..”
