Overall positive experience.

Hard to be jazzed about a storage unit. Everything was fine. Based on customer service standards these days, delivering to expectation is a rarity. All went well. No reason to go anywhere else.

Clean, climate controlled storage

We had a unit for almost two years. Everything was just as clean and preserved as it was when we originally stored it. Property and unit were clean and climate control worked beautifully. Staff was friendly and efficient.

Patricia Ford Aug 10, 2020

Very convenient and a great staff..

Having to store all of my belongings in between closing on the sale of my house, and before the closing on my new house presented a problem. Sentinel Storage was close by and I was allowed to start my month on any day. I needed to store my things beginning on the 18th of July and I could get into my new house yesterday.Also, when I realized I needed another storage unit, the staff found another one as close as possible to the one that I had already rented.

A wide array of units, anytime availability, and superb customer service

Sentinel Storage was able to meet all of my storage needs on very short notice. With plenty of units on offer, an incredibly friendly and helpful staff, accessibility for both cars and trucks, and the best rental terms in the area, they provided by far the best storage experience I have had both in Delaware and across the country. Absolutely recommended for anyone in need of extra space.

I had a great experience with Sentinel Storage. The units are easily accessible by car or truck.

Convenient location, easy access, friendly staff, clean property

Deborah helped with sizing the unit based on our belongings coming from Illinois. The property is clean and is easily accessible. We chose an environmental unit due to diversity of household goods being stored for a period of time until new house construction was completed. It is conveniently located in Middletown, DE with easy access to Highways 71, 299 & 301. Thanks for a great experience.

I always felt our possessions were safe and well cared for

We have been with Sentinel Storage for over 2 years and have worked primarily with Debra throughout that time. Because we travel a lot and are Florida residents, communication has been key. Debra always made sure we were aware of any changes in price or other policies during our 2 years there. When we talk to Debra in person she has always been professional and personable. I always felt she had our best interest in mind. I would recommend this facility. I felt safe whenever I was there and always felt out possessions in storage were safe as well.

Sentinel Self Storage is absolutely amazing!

I have used lots of storage companies over the years, and you come to expect poor service and trashy/dirty facilities as the norm. Sentinel however is not that at all. From the first moment I walked into the office it was clear that this company takes their business seriously. The office is clean and the customer service was amazing, very clear on what you are paying for and why, plus really great pricing. The grounds of the storage facility were super clean, and the unit itself was spotless. Can’t say enough good things about this company. I hate doing reviews or surveys, but with the experience I had I felt they’ve earned it.
