Hilary at Freeup Storage in Black Diamond is a pleasure to work with! Her level of customer service is far and above what’s norm nowadays. The overall facility is clean, secure, reasonably priced, and they had lots of options for us to from. Thanks Freeup and Hilary for helping us manage our storage needs in between homes! Being able to quickly and easily store some of our belongings so we could sell our house, helped us sell our home quicker and for more money, because we were able to free up the clutter that may have turned buyers off.
And Hilary, thanks for helping our young adult son navigate his first storage experience as he awaits his new home being ready!Facility Amenities
