I would like to share my experience with Mount Diablo Self Storage. For over 15 years I rented storage space for my business and personal use, and at times I had up to three units. They are always clean, professional and especially reachable which wasn’t the case from other companies I’ve used in the past. There’s nothing glamorous about storage, you just need everything to work when you need access and reach someone when you need them. By the way… Manager lives on site. Joe Dajani

I have used Mt Diablo Self storage. For many years when I need storage. They have a safe professional ran business. Else I would not return. But I do. No bugs came along while my things were stored here. Which I totally appreciate! No scary people hanging around. I always feel safe going here Even alone. The office staff is amazing and friendly professionally. 5 Stars is my truthful rating! 💞⭐⭐⭐⭐⭐
