Read some helpful reviews of Sentinel Self Storage at 504 Industrial Drive, shared by real renters with genuine experiences and honest opinions.

No attendant at first storage location. Hard to find attendant at second location. Then he puts pound sign where star is supposed to go on card so we couldn't get out of gate. He said it was his first day at that location. Didn't offer lock but asked if I ever rented a storage unit before and I said no. This was his opportunity to make a sale . ... Read more

I needed a storage unit for all my personal belongings while seeking an apartment in Middletown. I had a large collection of books that I was particularly concerned about, and Sentinel Climate-Controlled storage was the perfect solution. I rented a 10'x20' CC unit for two months (second month free) and removed my stuff after six weeks when I got a place to stay. We had a huge amount of rain during this time - heavy thunderstorms, all-night downpours, repeated lines of showers, the works. The storage unit and the access aisle were bone dry - not a drop of water. The temperature and humidity in the unit were very consistent, and even the driveways around the facility drained quickly. Getting to know Pat and Elaine was an added bonus. They were friendly, helpful, and knowledgeable. This was my first experience with a storage facility, and it was totally positive. ... Read more

We are using Sentinel Storage while our home is being built. Our experience with this facility was excellent. Pat handled everything in a friendly, professional manner. The storage unit, as well as the entire premise, is neat and clean. I would not hesitate to recommend Sentinel Storage. Thanks, Pat, for all your help! ... Read more

I needed a storage unit in Delaware because I was moving up from Florida. When I called about Sentinel in Middletown I got someone on an 800 number that gave me all the wrong info. I was told someone in Delaware could come into the office on my behalf and reserve a unit for me, when my friend did so she was told by Miss Pat that we were given the wrong info. I then called Miss Pat explaining my situation that I would not be in Delaware until Sunday and I had to have my 26 ft moving truck returned on Monday morning. I was in a panic and very pressed for time. Thank god for Pat, she was so kind and put my mind at ease and was willing to come in on her day off and when the office was closed to help me get a unit. Pat went above and beyond the call of great customer service. She really saved me a lot of extra stress and from going somewhere else with my business. I would recommend Sentinel in Middletown to everyone!! Besides the wonderful ladies that work there it really is a nice, clean and safe storage business!! Thank you again Miss Pat for being such a caring person and willing to go the extra mile, that is so rare these days. Please give this woman a nice Christmas bonus!!! ... Read more

This particular storage facility provides self storage units of different sizes, ranging from 25 to 150 square feet. Space is not an issue! If you have more belongings to store, or simply bulkier items or even vehicles, you should go for larger storage units.

You already know how much stuff you need to put in self storage, so figuring out the unit size you need is the next step. Smaller units such as 5'x5' or 5'x10' spaces can usually be filled with the amount of items you would normally store in a closet: a few chairs and lamps, sports equipment, garden tools and some boxes.

Moving on to larger sizes, imagine the 10'x10' and 10'x15' units as similar to a bedroom or a living room – larger pieces of furniture, sturdier equipment and bicycles can fit here. Finally, a 10'x20' unit has enough space for the contents of a 3-bedroom house, while the larger 10'x30' space easily accommodates the contents of a loaded semi-truck.

Accessibility and quickness are key when it comes to storage, so drive-up storage units are generally regarded as very convenient. Pull your car right up to your storage space, load, unload, and you're good to go! However, if you're mostly storing temperature-sensitive items, you should rather consider indoor storage units.

Climate-controlled units maintain consistent temperatures and humidity levels all year round, making them perfect for all your sensitive items. Moisture and varying temperatures can damage a whole host of things, and that is why a lot of people choose to use climate-controlled units to store items like wooden furniture, electronics, artwork, documents and photographs, collectibles, antiques, etc. If the belongings you're storing are important to you, you should consider renting a climate-controlled unit.
