    Helena Security Storage is great. I needed to get a storage unit ASAP and they answered the phone even on Sunday. It took me little to no time to sign up online and getting in was quick and easy. Highly recommend. ... Read more

    I have had my unit for quite some time. I have been satisfied with the secure facility. The new owners are very easy to get ahold of and very helpful with any questions. Id recommend security storage to anyone looking for a safe place to store their personal property! ... Read more

    I can’t say enough good things about this storage facility under the new ownership! The difference is night and day — everything is clean, secure, and so well maintained. The new management team is super friendly, professional, and really goes out of their way to help. ... Read more

    Impossible to get ahold of management let alone someone who speaks fluent English in addition to their poor attention to the property they are hiking the rental prices. Don't waste your time at this run down place, its had multiple break ins and absolutely no protection for your belongings. ... Read more

    The property is accessible always and never closes. It gives me peace of mind knowing that I can have access to my stored belongings or can bring items to store at any time of day for whatever reason. It has a pin code secured gate and security fence as well as cameras. ... Read more

    I got an email saying I moved out of my unit when I didn't a month before my actual date, and called to talk to someone and so far I have sat on hold for a half hour waiting to talk to someone. I have a 10×15 storage unit full of everything for a home for my 5 kids and I. Im a single mom. Potentially going to lose all of mine and my kids things ... Read more

    I don't know if Security Storage even reads this review. I don't know if their company even exist anymore . I have been trying personally and members of my family have been trying to get in touch with someone from security storage from the past 2 weeks. As of the writing of this review it is June 2nd 2021. I have called their phone number numerous times only to get answering machines. There is no email address that I saw on their website in order to get in touch with them. I've been trying to get in touch with them so I could access my items on their property. Either the gate code has changed are the gate is non-functional. I'm trying to get in touch with them this way hoping that they can actually read this review. But I would suggest not doing business with this company until you can at least get in touch with them. ... Read more
