I let the front office know about door not closing properly and they didn’t take the time to confirm my issue with the door. I am not confident my items will be safe. They did tell me they will call and have a maintenance person go see, but could not tell me when.

As a college who goes home for the summer every year, I always look for a place to store away my school things. For two summers now I have been using CubeSmart self storage as I absolutely love working with them! From their great prices to amazing customer service every time I could not think of going anywhere else. I will definitely continue to use CubeSmart and hope that others will too! Thank you CubeSmart for everything!

When I arrived to move in my appliances I had movers with me who we're being paid hourly. They required an additional hour of time because the security gate was inaccessible to my new entry code and there was no one on the office. I had to go to the new apartment and have my movers take the storage appliances out of the front of the van to get to the apartment furniture, then reload the appliances and travel back to the storage facility. Not a good experience.

The space I booked thru Sparefoot was not the space that was reserved for me at CubeSmart. No one had explained to me prior to my reservation date that the 5'x10' space I reserved is actually TWO 5'x5' space next to each other. There was no other fine print in the reservation stating that fact, which is very misleading. I did not find out that was the case until I arrived at Cubesmart to fill out the paperwork, leaving me with no choice but to select another unit that fits my needs.

5' x 15' Storage Unit

It is approximately 75 square feet of space. This type of unit is good for the contents of a one-bedroom apartment with major appliances.

10' x 10' Storage Unit
It is approximately 100 square feet of space and about the size of a standard one-car garage. Holds furnishings of a one or small two-bedroom apartment with major appliances.

10' x 15' Storage Unit

It is approximately 150 square feet of space. Holds furnishings of a large two-bedroom apartment or smaller home. Great for storing large furniture and appliances.

10' x 20' Storage Unit
It is approximately 200 square feet of space. Holds the entire contents of a three or four-bedroom home up to 2000 square feet. Can also hold compact full-size vehicles and boats.

10' x 25' Storage Unit

Holds the contents of a large home, roughly 4 or 5 bedrooms, with large furniture, garage items, and major appliances.


What is the height of the storage units?

Storage units are approximately 8 feet high.


Do I need to rent a climate controlled unit?

If you have delicate items such as musical instruments, computers, pictures, antique wood furniture, it is recommended to select a climate controlled unit. Climate controlled storage units protect against rust, corrosion, mold, cracking, and warping.


What’s the difference between an indoor and an outdoor unit?An outdoor storage unit is one that has a direct access and usually drive-up accessible. An indoor unit is located within the building.


What items can't be put in a storage unit?

Most storage facilities will not let you store firearms, perishable items, liquids, illegal drugs, flammable and hazardous materials, live animals or plants.


Are my items insured while being in a storage unit?

You are responsible for the items that you store. Storage facility's insurance provides protection for the location that houses the storage units and not the contents of individual storage units. If your homeowner insurance doesn't cover your items, usually the facility manager will help you sign up with an insurance provider.


Can I use my renters insurance for a storage unit?

Anything your renter's insurance policy covers under usual conditions would be covered in your storage unit. Usually, renters insurance will cover items in a unit up to 10% of your policy limits, but the coverage does not include natural disasters. However, there may be exceptions to this, check with your insurance company to see if you're covered.


What do I need to bring with me when to rent a unit?

You will need a government-issued photo ID(driver’s license, state ID or passport) to complete your storage unit rental agreement.


Can I access my unit anytime I want?

Most storage locations are open 365 days a year, but access hours may vary. During access hours, usually between 6am – 10pm seven days a week, you can access your unit by using your individual gate code. During office hours, the company employees are available to answer questions and provide on-site support.


How long can I rent a unit?

Most rental contracts are month-to-month agreements and billed in one-month increments. No long-term lease is required unless the customer requests otherwise.
