    Read some helpful reviews of Diamond Self Storage, shared by real renters with genuine experiences and honest opinions.

    GO ELSEWHERE. Literally anywhere else. Absolutely by far to worst storage facility I have ever rented from. We left state to handle a family matter, ended up being gone for 1 entire year. After 6 months they double the cost. Paid well over $2,500.00 for the year and a half of service, got close to losing my unit several times (my fault) called every single month communicating we would pay and we weren't willing to lose our unit due to the sentimental items we neglectfully put within the unit. Finally arrived to clear out the unit and they had cut, and replaced my lock. They didn't just add a lock like the other units, they completely removed our lock to inventory our unit. They never informed me they removed my lock to inventory our unit. Of course we have to replace the lock before they will remove the lock from management. I am carefully making inventory of the unit to ensure nothing is missing. Received so much attitude from the staff when I arrived to clean out the unit, almost like they didn't want us to collect our belongings. Absolute garbage! ... Read more

    My experience with Diamond Self Storage has been flawless. Best rates in town, excellent customer service (Stephanie and Emma), an extremely safe and secure location, and the additional amenities/perks were unexpected. Thank you, Diamond, for going the extra mile. ... Read more

    My experience at Diamond Self Storage was a very easy process thanks to Wendy whom was the worker that helped me. She went over all the details very thoroughly regarding rules, regulations, and hour's of access. They offered up to $50 towards the rental of a Uhaul, and insurance options if you don't have renters or homeowners insurance.The unit was conveniently close to the gate, and was clean other than a cobweb or two. My only complaint was that the outside door to the access hallway of my unit sticks due to the concrete buckling under the door. They have had someone look into the problem. However, there is another outside door to the access hallway on the other side of the building. I do recommend if you are going to rent a unit to bring your own disc lock for your unit, or you can buy one from the storage office. ... Read more

    This is the second time I have rented a storage unit from this location. It was a good deal last time and it was even a better deal this time. The staff has always been very friendly and helpful. Today I dealt with Stephanie and she was very pleasant and very helpful and made the whole move-in process super easy. I got half price for one year for a 10x20 unit that no one could touch that price. I love the location and the ease of getting in and out of. Stephanie. Help me choose a location in the facility that worked really well for me. Last time I was here I rented a 10 12x35 unit to store my RV inside for the winter. I got a great deal and it was awesome. Can't recommend this facility enough. They have great security here. And that gives me peace of mind. ... Read more

    Signing up and getting situated was easier than sliding down, a greased ramp. Sara in the office is a darling, very helpful and accommodating. The facility is practically spotless and its clear they maintain high standards. One feature I really appreciate is that I can upsize my storage unit if needed and still maintain my half price offer for a year. ... Read more

    I've been storing here for years! The property is always kept clean and well kept. The security measures appear effective. The staff have been consisntrly friendly even remembering my name when I come inside the office to buy supplies or use the restroom etc. Inside the office, they've provided coffee or hot chocolate for those cold days, or sometimes cold bottled drinks on hot days ! These thoughtful gestures go along way to help make the customer feel seen and valued. Many different ways to pay monthly, which makes it easy to navigate. Special shout out to staff Stephanie who always welcomes me with a smile, assists me with my many questions and is overall a kind presence on site! Highly recommend storing here if you have a need for storage! ... Read more
