Our Pittsfield, MA, self storage facility provides convenient solutions for both residential and business storage. Drive-up units are available in sizes from 5x5 to 10x20, giving customers the ability to stop beside their unit and load or unload without using elevators or traveling through lengthy hallways. Those needing a more controlled environment can select indoor, climate-controlled units measuring up to 5x15. Stable temperature and humidity can be especially useful for furniture, electronics, photographs, and records. We also offer commercial storage, record storage, and portable storage, together with online payment options and customer service. Daily access hours run from 6:00 AM until 10:00 PM, while select drive-up units provide 24/7 access for added flexibility.

Downing II serves customers in Pittsfield as well as Dalton, Lanesborough, Lenox, Richmond, and surrounding Berkshire County communities. Straightforward road access makes the facility manageable to reach, even when customers are towing a boat or moving an RV or trailer. Vehicle parking ranges from 8x15 to 10x40, providing space for cars, RVs, boats, and trailers. Each parking space offers drive-up access, making it easier to pull in, connect, and leave when needed. The property is fully fenced and secured by a gated entrance, helping control access to the grounds. We built this location to provide simple, accessible storage for household belongings, business materials, and larger vehicles.

After calling over 3 companies without success. I finally found someone that answers the phone, Kevin is a very helpful and kind person, explaining me everything about the space I needed to rent, sometime that human touch is so easier!!! The space was clean and I got what I needed.

The staff at Greylock storage have been courteous and helpful each time that I have come to remove items from my storage unit. I have been renting a storage unit for about 6 years now. I have not had any instances of theft or other damage to my items.

I forgot to call when we got our new Greylock debit cards I September. Susan was wonderful- I didn't incur a late charge and she handled it all so well for me. It was greatly appreciated ... It's so nice to deal with "nice" people!!!

My family have mentioned me to check out Mullen's when I moved here. And I'm glad I did, they manage to have a storage unit available for me at the last minute during the start of COVID pandemic.
Units are at a fair price, the staffs are super friendly, helpful and always keeping me posted with rent, days that'll be closed and if there anything going on it the building.
I have no interest looking for a different storage

Mullen's storage has given me all the personal attention I could possibly need, deals effectively and efficiently with problems, keeps in contact and has never once disappointed me. I have had many storage places in many states over the years and Mullen's by far is the best.
