The units are clean and well-maintained, both inside and outside, and moving equipment is available at every building.

I truly appreciate their outstanding service. I've been with Mount Diablo Storage for many years, and I love this place. Pam

Other places I went to would literally say we don't do Uhaul after 3pm and say sorry - try tomorrow! To add insult to injury (hehe) my battery on my car died when I was in the parking lot. This time, the owner himself (I think he owns the place) came out and fixed my car! Man he really saved the day, I would have been so ... (explicit language) These guys here are no-nonsense people.. if you come in with a boorish attitude, they aren't going to put up with that, and I applaud them for that.. but if you are nice, they go out of their way to take care of you.. and so they did for me! The owners daughter was just as helpful, nice, cordial and professional when I returned. They understood my messy moving situation since another uhaul store refused to honor my reservation and left me stranded.. I am not going to say it was the Vallejo Uhaul.. that would be very mean for me to do.. it has to remain a secret! Anyway, for as long as I live in the Area, Fort Knox really went above and beyond to accommodate me and make sure I had a truck to move with. And they really didn't have to, that's why I give 5 star rating

Today I scheduled a locksmith to come out to remove my broken lot, scheduled with the un professional property manger Jasmine yesterday and when I knocked on the door to let her know I was here her good for nothing lazy boyfriend, baby daddy or who ever he is had an attitude and cursed me out for knocking on the door. If you wasn't being lazy you would have not been asleep at 1230p. Regardless of me disturbing that piece of crap, there is no reason to be un professional and and disrespectful. Jasmine with her unprofessionalism made excuses for him and was just as rude. If you don't like your job, then quit and don't take a job where you live and work at the same place. These employees need to be fired for the way they treat customers because if they did this to me today, they have done it to other customers as well. I wouldn't had had to hired a locksmith if when I filled out a request to get my lock cut off, they did it in a timely manner. The DM failed to come out twice, guess they were waiting to the first so they could collect more went on the crappy storage unit, I don't think so.
