Sentry Storage - Greenback

A pain free experience. Management always ready with an easy smile, professional, happy to help attitude. Clean space. Easy access in and out. Willing to work with folks. Do yourself a favor. Avoid the other storage facility to the east of this location. Cannot recommend highly enough! Hey guys.. really appreciate ya!

Horrible conditioned units with spiders, webs, etc. inside and around handles of units yet that I understand and more of a FYI as I understand it’s what I signed up for with outside units. Yet the main reason for 1 star is because they are a scam by “advertising” such great online one to get you to move in then increase rent on you. I have only been in my unit a little under a year and have had two price increases…then the just let you know it’s in the fine print. Yet I’m aware and have heard of storage places doing this but prior to this spot I had a space that I’ve had for probably 10 years which I barely just had a second raise yet 2 rate increases in less than a year…no thank you! - STAY AWAY

As always, the management was friendly and courteous. I have been a renter at Sentry Storage - Greenback for about nine years and they are always helpful and recognize me on sight. This visit was no different; my needs were taken care of with efficiency and ease. I consider the managers to be friends.

The owners are wonderful, and we’ve only had great experiences here. The ease of access, cleanliness, and quality of space was great. We always felt like our things were secured and safe!

⭐️⭐️⭐️⭐️⭐️ Absolutely the Best Storage Experience Ever! Sentry Storage has been nothing short of amazing. From the very first phone call to moving in, every single interaction I had with their team was professional, kind, and genuinely caring. They truly are the best people in the world to do business with. The staff went above and beyond to make sure I had exactly what I needed, explained everything clearly, and made the process stress-free. The facility itself is spotless, secure, and very well-maintained — I immediately felt confident that my belongings were in the safest place possible. What really sets Sentry Storage apart is their customer service. They don’t just treat you like another rental, they treat you like family. It’s rare these days to find a company that values people the way they do. If you’re looking for storage, don’t waste your time anywhere else. Sentry Storage is hands-down the best choice you can make. I couldn’t be happier with my experience, and I will recommend them to everyone I know!
