Brea

September 1, 2026

They get you with the intro rate and then raise it every renewal. Each year, my unit rate has doubled. I do not believe it is properly temperature controlled based on mold findings in my previous unit. The only elevator in the facility was broken for many days, something to consider if you have a unit on the upper level. On a positive note, Dustin is so helpful! I do not need a response saying to call the number; I understand the business model well. I live out of state and will not be using Extra Space Storage anywhere else based on my experience at the Mequon location.

We are truly sorry to hear about your experience at our Mequon Extra Space Storage facility, Brea. We understand your frustration regarding the rate adjustments and the issues you encountered with temperature control and mold in your previous unit. We also regret the inconvenience caused by the elevator being out of service. We are glad to hear that Dustin was helpful during your time with us. We appreciate you sharing your feedback and regret that your experience has impacted your decision to use Extra Space Storage in the future.
