I have always gotten extra great care here at StorageMart. Tim, the manager, has repeatedly gone out of his way to help me feel welcome and to have the services and storage resources that are right for me. I am very pleased and impressed. It is rare these days to find a business that puts such a priority on taking great care of their customers.

The staff at this facility is extraordinary! They are always very helpful when I have questions or issues with my account. They keep the facility in top-notch condition and I feel very comfortable that my things are securely stored here. Thanks!

Beginning to end StorageMart and staff are great! Eden was wonderful in showing me units, explaining prices and sharing all of what StorageMart had to offer. I returned later to complete the rental papers with Tim and once again was very pleased with the customer service and professionalism that was displayed. Everyone here is willing to help and assist with all your needs while moving. You wont be disappointed when choosing StorageMart!

I've been happy with this place. Was given 24 hour access which is very helpful.

StorageMart in Norwich (formerly Big Box) is without doubt the best storage company I've ever used. Hassle free, helpful, super staff - and always a competitive rate, they work with your needs. Best guys in town.

I must admit to a personal bias - I have worked with the manager here (Tim Mauroni) while employed by the Mt. Diablo School District. On renting here, Tim led me through my options very carefully, determined that my needs were correct, explained my future options, and took me through all the paperwork ensuring that I fully understood each step. This a clean, well-maintained site...excellent security, flat carts available for moving multiple or bulky items, and as a bonus has elevator access. Overall, it earns the five stars posted.

I like the facility, clean and secure. Convenient location. Tim the manager is always helpful My only issue is that the price per unit goes up every three months. I am a long term user, I have 2 units and remain there because who wants to move two units. Please stop raising rates on long term, greater than a year at least, tenants.

I rented online before seeing the facility and my only complaint was that it was advertised as first floor but the unit ended up being on the third floor which is slightly more inconvenient. All in all it was a good experience - the manager was very professional and knew is company's policies/rules inside and out.

My first experience with a storage unit. I needed just a small space to store jewelry supplies & displays for the flea markets I do. I have a small indoor unit. I wasn't sure about getting an upstairs unit but I can park right next to the door, load and move things on their dollies, and the elevator is quick. It's not climate controlled but that doesn't matter for my supplies. The location is very convenient. Never crowded and has always been clean when I'm there.

The manager was very rude and he not very helpful. The lady that works on the weekend is very helpful and curteous. This is my second time storing in Storage Mart the place is clean. If not for the rudess of the manager everything is good.

Poor costumer service. I got there 15 min before closing time, and the guy said that he couldnt help me because it was too late.

the unit itself is exactly what you might be looking for in a mini storage. clean, personal lighting, secured and semi private. HOWEVER THE STAFF AND THE ADVERTISING ARE AT TOTAL ODDS WITH EACH OTHER. I rented here because it said 24/7 access (by reauest) THAT IS A COMPLETE LIE I HAVE EVEN ASKED (AKA requested it) AND STILL GET TOLD IT IS NOT AN OPTION. AND online it says till the 6th becore locked out. Tim gives you till the END OF THE FIRST... well today is the SECOND AT 1041 am AND WE ARE ALREADY LOCKED OUT. SO I FEEL HORRIBLY BAD FOR THE PEOPLE THAT GET PAID ON THE 3RD or any day that is not the 1st.... then we are all stuck paying for however many days each amd every month that we are unable to access our unit. As if it is not bad enough that Tim and his sidekick are out POLICING all tennants, complaining about use of hand carts, or visits per month others have or (the WORST) TIM CUSSING AT RENTERS FOR HAVING AN ARGUMENT ON PROPERTY!!! THE ARGUMEMT WAS BECAUSE SOMEONE (other renters that are ALWAYS BUDDYING UP WITH TIM) pushed their vehicle and that vehicle is not a stick shift so something got broekn when they did thay- and the couple was arguing because one lost the keys... because TIMS friends moved a vehicle (without permission and SNAPPED something on the couples suv) TIM then seizes this time to YELL AMD CUSS AT THEM SEPARATELY. I PERSONALLY SAW THE POOR GIRL MINUTES LATER amd she was BAWLING!! And yet he just sat thefe GLARING UNTIL SHE PULLED AWAY.... IF YOU ARE NOT 100%PERFECT OR IF YOU HAVE A 9-5 JOB FO NOT REMT HERE HIS ROID RAGE WILL GET YOU YELLED AT OR WORSE....

Everyone knows that moving can be a big pain in the Buns. Especially when life sometime throw's you a curb break-up, relocation with job or even a new place...
