This is a new, clean, secure,well managed and well maintained storage company. Chris answered all questions and helped us in several ways when we were stressed from a cross-country move. It's a great place and seems to be state-of-the art in security, records and billing. We've already told others about it.

**Outstanding Customer Service!** My husband and I rented a storage unit at Lake Helena Storage for the past two years, and we couldn’t have been happier with our experience! What really impressed us was how clean this place is and a great location. Also we want to express their kindness and appreciation for their customers. When it came time to move out which was a last minute decision, we learned there was a 10 day notice requirement. However, because we had been good renters, they graciously waived it for us. We sincerely appreciated that kind gesture. We would absolutely recommend Lake Helena Storage to anyone looking for a storage facility. Thank you! ??

Super easy process online, and with the staff over the phone. We were very happy with our experience! Clean, simple, effective, close to town, and kudos to staff who were very responsive and went above and beyond to make sure we had everything we needed. Be cognizant of access hours (it’s not 24/7) and that you need a security code to enter that is provided after paying online.
