    Read some helpful reviews of Extra Space Storage, shared by real renters with genuine experiences and honest opinions.

    We closed our account on Saturday, Sept. 28th with confirmation in hand. Since the office is closed Sundays, the system bumped the move-out date to Monday, Sept. 29th—which we never agreed to. We returned the lock and key on the 28th (our billing cycle end date) and called the next morning to confirm the account was settled. Later that evening, I received a call from a worker (Diana) who was immediately rude, dismissive, and threatening. She claimed we now owed a full month’s rent ($151) because the system showed 9/29 as the move-out date. When I questioned why my online confirmation clearly was able to select 9/28, she refused to listen and simply repeated “collections” over and over. My husband then called and got the same hostile treatment. She refused to speak to him unless he three-wayed me in to “authorize” him, even though he’s a registered account contact (which we later confirmed). Once she finally spoke to him, she suddenly offered that we could pay for just one day — but only in cash. That option was never offered to me, and a “cash only” requirement for a corporate storage facility is beyond questionable. When my husband went in person to the Seabrook location to settle this, he overheard Diana’s boyfriend sitting in the office, insulting us out loud with profanity (“those disrespectful motherfers”) while she laughed and agreed.* Completely unprofessional and unacceptable conduct. And the final proof of their dishonesty? The receipt they gave us shows the close date as 9/27. Meaning we were right all along, and all the harassment, collections threats, and cash-only demands were completely fabricated. This is one of the most unprofessional and shady business experiences we have ever had. From fabricated billing to harassment and profanity in front of customers, this location is an embarrassment to the Extra Space brand. Consumers beware: Do not trust this facility. They will manipulate dates, threaten you with collections, and treat you with open disrespect. Take your business anywhere else. ... Read more

    Easy to get moved in! James was on the site and was very helpful and polite. The facility is very nice and clean. It’s a place I recommend to anyone that is looking for a place to store any of your possessions. Ask for James and he surely will take care of you! ... Read more

    There is never a cart available. I walked the entire facility yesterday and not one cart was to be found. Before I signed a rental agreement I was assured there would be carts available at all times; carts were available initial move in but I have not seen once since. Also, my rent went from 145 to 225 and there isn't one additional benefit or amenity to warrant that type of increase and I've only been there about since April. ... Read more

    I had an amazing experience with this storage company. I called and spoke to James, he helped get me set up so when I walked in it was a quick and easy process. He also gave me a promotional deal for a free month! When I got to the office, Dayna was so helpful! I actually needed a different size than I booked so she showed me the units and quickly got me what I needed and also found a promotion for me. I would recommend this location and company. ...

    DayNa was AMAZING! She went over and beyond to make sure I got a good rate for my storage rental. They were having technical difficulties when my daughter and I went earlier in the day and she stated she would call me back later on in the day to finalize everything. DayNa NOT ONLY found me a good rate she found one at a different location. I thank her! Her customer service went beyond my expectations! Way to go DayNa and Extra Space Storage for EVERYTHING!! ???????? ... Read more

    I have been checking out different locations lately & came across the Seabrook location. Immediately after walking in, I was greeted by Dayna. She was very professional & very kind!

    I have rented an INDOOR unit #1030 here for several months. I paid $122/m starting out. Now $156/m. Only to return here and find all my belongings covered in rat poop and pee. I do not recommend anyone to rent from here if you have valuable items needing stored. That $1,676.00 that I just paid for rats to live, poop and pee all over my belongs. ... Read more
