Reserved our 5x15’ storage space online, and was promptly followed up on phone by Amanda asking if we had any questions. We missed our original move-in date due to an issue with our u-Haul on moving day, and were easily accommodated. Had a seamless payment and had our first load in the storage within 15 minutes of showing up. Highly recommend!

Would highly recommend Mini Mall Storage! I’ve never had any issues that weren’t quickly resolved and the staff are all very friendly and professional. I always have access to my locker when I need it (with my personal code to get in after business hours) and I was able to find a locker that perfectly fits all my things.

I’m so glad I decided to store my important belongings with Mini Mall Storage in Cornwall. I appreciated the fact that was able to speak to someone in person and not by telephone.

Everything is kept very clean and bright and I highly recommend Mini Mall Storage as an excellent place to store your belongings.

The unitwas great. The staff was very knowledgeable and helpful. I was finished with my unit the end of August. I phoned and left a message to say I was vacating. I was charged for September. I missed the part of the contract asking for 10 days notice prior to ending the contract. I was hoping for some leniency. I know a contract is a a contract. I was thinking a little discretion and they could refund September. No such luck. So be aware. Other than that it was a overall good experience. Kind regards to all Kevin M

The best part of renting storage here is the great customer service provided by Angela. She always goes above and beyond and is very friendly and professional. They should be thankful to have her as an employee because I would have probably found another storage option but she is the bright star.

When i rented the 10 x 20 it was great, then i moved to a 10 x 10, There are mouse droppings everywhere, the door does function properly, and i did point it out and was told it would be fixed. It was not. I have recently explored other places in Cornwall that have much more to offer at far less price. Even the overpriced insurance will not cover what happens here.Renters BEWARE ! And the prices I see on the website are far more upon signing.

So my hubby like second nature put the lock back on the unit after clearing it out. That was the 29th. So when we saw that they took another payment 4 days later even though it was empty. We called to see why, forgetting he put the lock back on. They tell us that that's why. Instead of just giving us a call and being honest good business owners. You tell me you checked for 4 days in a row,then take out another payment, knowing we had given you proper notice you could have given us a quick call. Simple and easy. Check your cameras you knew we had moved out. Very sneaky and dishonest way to do business. That money was donated to us because we were homeless due to a flood and we lost everything. That money was to help me get beds for my children. Never will I ever do business with Cornwall mini mall storage again or recommend them. Just terrible, feeling robbed.

Awful customer service. This location was closed without notice upon my moving day, so I had to scramble to find a new storage facility. I was issued a refund, after multiple separate calls and emails, but still was charged a nominal fee for a service I was unable to even use! Save yourself time and energy, use the uHaul storage on the other end of Cornwall. It is easier to access, safer to use, and the customer service is infinitely more professional.

Use to be a good place to rent with good honest people. Now the organization that runs it is a joke. I needed storage today. I went online and got a web rate of $176. PLUS insurance k that's new, but I can understand it. Plus a facility fee. What? Yes a facility fee. When asked about that I was told it's an environmental fee, carbon fee plus it's a fee to help with any of my storage "Needs'" while renting storage"answer questions and things like that plus to help pay for the facility. None of this was mentioned on the web site of course so that incredible web rate of $176 per month is actually over $250 per month. 1 star

Dealing with this company has been an exhausting and costly experience. We lost $20,000 worth of our inventory to them. Both our attempts to settle terms and make payment lead to terms being changed moments before payment was scheduled to go through, effectively jumping up the cost to us by 4x or more. This sudden change caused us to halt the payment, and as a result the situation was never resolved and we lost our vehicles. To their credit, there were very patient with us while we tried to resolve the situation, but in the end, they refused to adhere to their own terms, and so it was just delaying the inevitable.

These guys screwed me over hard. I assume it's a one-person show over there, because if the lady I talked to had a boss, they should know that she is losing business and costing them money. I assume that Angela owns the place, because only an owner could operate so irrationally against the interests of their own business. I rented from them for almost 5 years, and then my payments lapsed because of a cascading tragedy in my life. I was given a deadline to pay the past due and late fees. On the day of the deadline they wouldn't take my payment. They delayed my payment and then changed their story several times, ultimately set me up to have a call-in race against other tow companies to recoup my own property, which they refused to continue storing even with all debt paid off---- then I was told I had till the end of the day to arrange a tow... then I was told that they had already called companies to tow my vehicles off. The story kept changing all month long leading up to this, the "auction" that never happened... etc... No rational response was accepted, and that tells me that there was another agenda going on behind the scenes. I entrusted them with two extremely rare, valuable vehicles and they strait up lied to me, refused my money and took them.

If the stated goal of this organization is to achieve 5 star customer service, they are losing the battle in a big way these days. This was made abundantly clear yesterday when I tried to call a local number for my location and was re-directed to a central phone answering service. This was not after hours. I asked to be directed to my location so I could speak directly with Angela but instead got put in an automated phone queue where I had to answer questions to properly direct my call only to have have the call get lost in an endless loop, unable to connect. Frustrating. Customers want to have direct contact with the folks who are on site and custodians of their goods. When I deal directly with Angela, I always get 5 star service.

Have a Question?

A 10 x20 storage unit is around the size of a single car Garage. We recommend this size for more significant self-storage needs, like freeing up space to stage your home, during a remodel or in between moves.

A 10×10 is about half the size of a standard garage. With the capacity to hold a king-sized bed, larger bedroom furniture, and oh-so-many boxes, the options for this unit are expansive.

A 5×5 is about the size of a walk in closet. While it’s small enough to easily manage household clutter, seasonal decor, and boxes, it’s also great for appliances, small furniture, and odd shapes like camping gear or sports equipment. Think of it like a walk-in closet that isn’t attached to your bedroom.

To rent a storage unit with Mini Mall Storage, you’ll need a valid form of government-issued ID, such as a driver’s license, passport, or provincial ID.

We do not allow tenants to store stolen or illegal goods in our storage units. Additionally, we disallow flammable or hazardous items, combustible items or liquids, plants, perishable goods, or animals. For additional and more specific information about what you cannot store, please contact us.

Drive-up storage units allow tenants to drive up to, load, and unload their storage unit. This is especially useful for transporting large items. Drive-up storage units are tall, convenient, and located on the ground floor so that you don’t have to navigate stairs or elevators.

Absolutely! It’s important to us that your belongings are protected. Therefore, we require all tenants to hold a valid insurance policy. Get covered with your own insurance plan and provide proof of coverage with your policy number, coverage overview, start date, and expiry date. Alternatively, we offer tenants coverage through our Mini Mall Storage Protection Plan. Speak to your Storage Concierge Specialist to learn more.
