    CarrieAnn was the BEST to talk with. First time storing dorm room items from across the country and she answered all my questions - even clarified if I needed it to be repeated or misunderstood. She provides all the details for what to expect when moving items in and out. Thank you!!! ... Read more

    Carrie Ann is always so pleasant! I was going to move my belongings out of Extra Space due to the pricing going up. But Carrie Ann in south windsor got me a great deal! Thanks to her I just switched locations rather than storage companies! She’s awesome and always has a smile. ?? ... Read more

    Had my car in here for less than a month, I set up several mouse traps. I would come by every 2 days to check on it, and always had a LEAST one dead mouse, sometimes 2. The structure is not very tightly sealed, there are openings of daylight in little walls between the garage doors. I tried sealing them with some aluminum duct tape, but they still get in some how. Also, after a major rainstorm last week, the cover on my car was all wet! So there is water coming in from the roof. Not good. So for now, I just brought my car back to my house. Thank god the first month was free! I would have been bitter if I had paid 150 bucks, to have water leaking in and non-stop mouse traffic. ... Read more

    Frequently Asked Questions

    The right storage unit size depends on what you plan to store and how much space you need to move around your items.

    5x5 or 5x10 units are great for smaller loads, such as chairs, lamps, small furniture pieces, boxes, books, and documents.

    10x10 or 10x15 units work well for larger furniture, bicycles, appliances, and the contents of a small apartment.

    10x20 or 10x30 units can typically fit the contents of a three-bedroom home, including large furniture and multiple appliances.

    If you’re unsure which size is best, a unit size calculator can help estimate the right fit based on the items you’re planning to store – helping you avoid paying for more space than you need.

    To open your storage unit door, start by unlocking it, whether it uses a traditional padlock or a Bluetooth-enabled smart lock. Once unlocked, grab the bottom handle and lift or pull up the roll-up door until it’s fully open.

    If you’re using the unit for the first time, make sure the lock is properly removed before opening the door to avoid damage.

    Security helps protect your belongings while they’re in storage and gives you peace of mind between visits. Many self storage facilities use a combination of features such as video surveillance, gated access, on-site management, and well-lit premises to help deter unauthorized access.

    Yes, most standard vehicles can be stored in self storage units. A 10x20 unit typically provides enough space for a car, while outdoor or designated parking areas may be available for larger vehicles.

    • Hazardous, flammable, or toxic materials
    • Perishable food
    • Live plants or animals
    • Cash, firearms, or irreplaceable valuables

    Always check with the facility at 688 Sullivan Avenue South for specific restrictions and recommendations.
