Read some helpful reviews of Diamond Mine Mini Storage at 4400 Horner Street, shared by real renters with genuine experiences and honest opinions.

I've been a customer at this facility for many years. Management has always been wonderful people. This time, is no exception. Ana, the new property manager, has been so helpful, so kind, understanding and patient. I have always been sad to see the management change, but am extremely happy with Ana and her team. No complaints and nothing but praises from me She has helped me consolidate multiple storage units to save more money and helped make the transition easy. During the consolidation of the units, she offered for us to use equipment they had on site to make it easier for us. Thanks for being awesome guys! That means you too Wally ?? ... Read more

Been associated with this storage for 5 years and counting. Impeccable service, clean units all the time no matter the weather. I recommend EVERYONE here, they have the best rates compared to any other storages I've looked at. Private mailboxes are perfect for when I get packages so they don't get left at my doorstep and potentially stolen. Cheaper than the post office too. 11/10 rating. ... Read more

I have rented here for over a decade. We came here the first time because they had one of the best security records in the state (my ex knew how to figure that stuff out) and they have always been the kindest, most accommodating people. Very flexible and understanding, and very helpful. Clean, secure environment, well lit and handled with great care. Can't say enough nice things about them. ... Read more

Frequently Asked Questions

Storage units available at Diamond Mine Mini Storage - 4400 Horner Street include the following amenities: Indoor, 24 hour access, Drive-Up Access, Retail Available, Onsite Manager, Truck Rentals, Security Camera, Gate, Parking, Credit Cards Accepted, Enclosed, Multi-Level Storage, Online Payment and RV Storage. Depending on what you need to put away in storage, you can discover there are some things you absolutely need, so make sure you check with the facility manager that you'll find everything you need on site.

You already know how much stuff you need to put in self storage, so figuring out the unit size you need is the next step. Smaller units such as 5'x5' or 5'x10' spaces can usually be filled with the amount of items you would normally store in a closet: a few chairs and lamps, sports equipment, garden tools and some boxes.

Moving on to larger sizes, imagine the 10'x10' and 10'x15' units as similar to a bedroom or a living room – larger pieces of furniture, sturdier equipment and bicycles can fit here. Finally, a 10'x20' unit has enough space for the contents of a 3-bedroom house, while the larger 10'x30' space easily accommodates the contents of a loaded semi-truck.

Accessibility and quickness are key when it comes to storage, so drive-up storage units are generally regarded as very convenient. Pull your car right up to your storage space, load, unload, and you're good to go! However, if you're mostly storing temperature-sensitive items, you should rather consider indoor storage units.

Climate-controlled units maintain consistent temperatures and humidity levels all year round, making them perfect for all your sensitive items. Moisture and varying temperatures can damage a whole host of things, and that is why a lot of people choose to use climate-controlled units to store items like wooden furniture, electronics, artwork, documents and photographs, collectibles, antiques, etc. If the belongings you're storing are important to you, you should consider renting a climate-controlled unit.
