    I had a great experience working with Stephen W at Extra Space Storage in New Castle, Delaware. From the moment I walked in, he was professional, knowledgeable, and genuinely focused on helping me find the right unit for my needs. Stephen made the entire process smooth and stress-free—he took the time to explain all my options, answered every question thoroughly, and made sure I felt confident in my decision. It’s clear he takes pride in providing excellent customer service. If you’re looking for storage in the area, I highly recommend asking for Stephen.

    I am extremely disappointed with my experience at Extra Space Storage and would not recommend this facility. The biggest issue is what feels like a classic bait-and-switch on pricing. The introductory rate seemed reasonable, but it increased significantly not long after moving in. The way the pricing is structured feels misleading — low to get you in the door, then raised once you’re committed. On top of that, management has threatened customers with fees and even collections over throwing away trash in the dumpster area. Simply disposing of trash became an issue, with warnings about additional charges. The tone of communication is aggressive and intimidating rather than professional or customer-focused. Snow removal has also been poorly handled. After a horrible snowstorm, the property was not properly cleared. Drive lanes and access areas were inadequately plowed, creating unsafe and inconvenient conditions for tenants trying to reach their units. Basic property maintenance should not be this inconsistent, especially when customers are paying steadily increasing rates. Another major frustration is that the site will close access for “maintenance” with nothing more than a paper sign taped to the door. No advance notice, no proper communication — just a sign. Meanwhile, customers are still charged full price even when they cannot access their units. Between the surprise rate hikes, threats over trash disposal, poor snow removal, and lack of communication about closures, this has been a very disappointing experience. I would strongly advise others to carefully consider whether this is the kind of business they want to deal with before signing a contract. ... Read more

    Got my storage less than a year raised the price a couple times I was told it may raise every year not multiple times a year? I should've researched more but mom was dying got storage a few months then she passes and they raise the price then we're trying to deal with everything boom price increase again geez. I really was hoping I would like this place because they were friendly but with the beginning had to climb flights of stairs with all my items because the elevator didn't work and it wasn't one time it was multiple days I came the last time I could not take stuff back that's why we took stairs when elevators were broken. Just watch out for price increase not a little either like almost double and sometimes over double it's crazy yeah they try to help lower it but I mean when u are increasing let's just give example say 100 increase then 100 increase again and that's less than a year 200 increase in less than year u see how that's just so much money. Again I was just giving example but you get my point it adds up way more than a dollar store .25 increase just so unhappy ... Read more

    We were with them a little while but the last few months were not good. First I went in to add stuff to my unit, however the elevator near my unit was broke down. Then several weeks later I had to get something from my storage unit and there were signs hanging up saying the the bathroom was not working. Finally a couple of weeks after that I received a notice that my locker rent was going to be raised. I expect a little each year, but they were going to almost double the cost, which is excessive. I was able to find a different climate controlled locker not far from here for a little more than half of what I was paying. ... Read more

    Leasing a storage locker turned out to be a surprisingly smooth and positive experience! From the initial inquiry to moving my belongings in, the entire process was handled with professionalism and care. The facility itself is clean, well-lit, and feels very secure, which immediately put my mind at ease about storing my valuable items. The staff I interacted with were incredibly helpful and friendly. They patiently answered all my questions, explained the different unit sizes clearly, and helped me find the perfect fit for my needs and budget. The paperwork was straightforward, and the move-in process was quick and easy. Having access to my belongings whenever I need them is a huge convenience, and knowing they are safe and protected gives me real peace of mind. If you're looking for a reliable and hassle-free storage solution, I highly recommend checking out this facility. It definitely exceeded my expectations! ... Read more

    Stephen and Satara are wonderful employees who have assisted me with all my needs. I have to give a big shout out to Stephen because he has helped me on more than 1 occasion and initially set me up. I am so appreciative of the staff and have used other storage facilities that can not touch this site. Thank you both for your great customer service and assistance ?? ... Read more
    Jahmahl H. - 20 February 2025
    Was here for almost 2 years. We lived in Newark so the drive was quick and easy down Rt 1 so super accessible. No complaints about anything, the place was well kept and had no real issues at all. Our rental for our 5x9 unit jumped about $50 when we decided to move out, which is the only real reason for us leaving, but assuming that’s just the new cost of storage units these days now. Satara in the office was super nice getting everything squared away for the move out. Would consider this location again if we moved closer and pricing was a little less expensive, but please know you’re getting a nice place for the price. ... Read more

    The employees here are very helpful, they were very nice and assisted a lot every time we needed anything. The units are easy to use and I liked the security of it. But we had our unit for only three months before our price DOUBLED ($80 to $160 for 5x10). I know the price we registered for was promotional, but doubling for a small unit is crazy!. We decided to move out and while we were in the office waiting for help, we overheard an employee saying their algorithm is what doubles the price, but they can “work with us”. However I was constantly receiving calls about my payments being late (times are hard, sometimes I have to wait until payday). When they called me, they should’ve noticed that my price doubled and offered to help. When moving out, we noticed a bunch of our stuff had mold on it. Any fabric material that wasn’t in a container was covered in mold. Mold growth for only being in a unit for six months is horrible. So much for climate control. We moved down the street to a unit for $55/momth, please save your money. I gave two stars simply because their customer service is top notch. ... Read more
