Having the opportunity to rent a storage unit online was something I’d never heard of. It was easy. It was quick. It was convenient. On the day that I got there, Tim greeted me to make sure that I knew where everything was. He walked me up to my unit, opened it and showed it to me. There are flatbeds that you can use there. There’s an elevator. It was very convenient. Choosing to rent here was definitely a great decision. ... Read more

I couldn’t be happier with my experience at StorageMart! From the moment I walked in, the staff was incredibly helpful, professional, and genuinely friendly. I had the pleasure of working with Rachel, and she truly went above and beyond to make the entire process smooth and stress-free. Her knowledge, patience, and warm personality made a lasting impression—she’s a true asset to the team! The facility itself is spotless, well-lit, and very secure. I love knowing that my belongings are being stored in such a clean and safe environment. The climate control works perfectly, which was important for some of my more sensitive items, and I really appreciate the easy access hours. What really sets this place apart is the attention to customer care. Every interaction was positive, and any questions I had were answered quickly and thoughtfully. It’s rare to find a business that treats you with this much respect and professionalism these days. If you’re looking for reliable, top-notch storage with amazing service, look no further.

Frequently Asked Questions

There is a wide array of amenities available for the storage units that StorageMart - 5115 Clayton Road has to offer. These amenities include Indoor, 24 hour access, Drive-Up Access, Retail Available, Onsite Manager, Contactless Renting, Security Camera, Gate, Credit Cards Accepted, Keyless Unit Access, Multi-Level Storage and Online Payment. Most of these amenities can prove to be very useful depending on what you need to store. For example, climate-controlled units can come in handy for keeping sensitive items, drive-up access can make your loading and unloading process easier, and extra security measures will ensure your items are kept safe at all times.

The storage units offered by StorageMart - 5115 Clayton Road can satisfy all of your storage needs. Different sizes here range from 25 to 600 square feet. You can go for smaller units if you don't have a lot of items to store, while choosing a larger space is recommended in case you need to store a lot of furniture, bigger items or even vehicles.

The unit size that you should choose obviously depends on how much stuff you need to store. On the one hand, you should think of smaller units (5'x5' or 5'x10') as closets – they can be used to store chairs, lamps, moving boxes and sports equipment, along with smaller pieces of furniture, books and documents.

On the other hand, the 10'x10' and 10'x15' spaces are good for storing larger items of furniture, bicycles and a larger number of possessions. If you need even more space, then 10'x20' and 10'x30' units can easily accommodate the contents of an entire 3- or 4-bedroom house.

We know that when it comes to self storage, there is nothing more important than quickness and accessibility. Drive-up access is an extremely convenient amenity, as you can park your vehicle right next to your unit, making it significantly easier to load and unload the items you will use storage for. However, drive-up storage units tend to be outdoors, so you might consider indoor storage spaces with climate control if you're looking to keep temperature-sensitive items in peak condition.

Yes, you might, depending on what you need to put in storage. Climate-controlled spaces keep temperatures and humidity levels consistent all the time, which means they are perfect for storing sensitive items. Seeing that a whole host of things can be damaged by varying temperatures and excessive moisture, many people choose to rent climate-controlled units for personal items such as documents, photographs, paintings, collectibles, electronics, wooden furniture, antiques and even vehicles. If you're looking to store such items that are valuable to you, consider renting a climate-controlled unit!
