I had an excellent experience at this Public Storage location, thanks to Tsegab and Carlton. From the very first day I opened my storage unit, they have always been helpful, professional, and kind. Today, when I arrived and there was ice in front of my unit, they immediately stepped in to help me without hesitation. Their customer service is truly outstanding. They go above and beyond to make sure everything runs smoothly and that customers feel supported. I am so glad I chose this location for my storage needs. Highly recommend! ... Read more

So-fun F. - 28 January 2026

I've been with this PS for 20+ years. This year my rent went up $100 a month to almost $500 a month. I knew it was a long shot but I went in to ask if anything I can do for a decrease, based on how long I've been there. Carlton, the manager there was fabulous. He was patient with me as we looked at solutions and keeping my unit with PS vs having to relocate all my 10x15 unit. PS did keep my current rate for six months, so no increase, and Carlton helped me reserve a new unit just four doors down from my current one, so while I have to move things - it's a good thing as I need to organize and purge - and saving almost $300 a month with my rate increase. Carlton was patient, and thoroughly explained everything and went above and beyond to ensure my new unit was near my current one, making the upcoming move easy. I was ready to move to another facility at around the same cost as my new rate, and am so happy that I won't have to go that route. I'm only giving this five stars to Carlton and his amazing customer service, not only to me, but to other customers I saw him interact with while I was on the property. I don't like some of PS policies and I don't like their $100 rate increases, but I do like Carlton and will stay because of him. ... Read more

I had the most helpful and courteous experience at the Public Storage location on E Diamond. We are a retired military family who have had the need of external storage on/off for the last 20yrs. Thru out those years it’s just been short direct to business customer service. But as of today we experienced exceptional customer service by Carlton and his co-worker (sorry I can’t remember his name at the moment) but he was equally exceptional. What made it exceptional was the compassion and non judgmental attitude towards our situation of feeling overwhelmed by needing space again after all these years. It might not mean a lot to most people but good help is hard to find and even more rare these days are engaged staff. Hats off to the 2 great employees at Diamond Rd in Gaithersburg your attention to details and approachable attitude was well received and I hope other customers take the time to acknowledge your efforts. ...

I had an absolutely wonderful experience at Public Storage, thanks to the exceptional customer service provided by Tsegab and Wendy. From start to finish, they went above and beyond to make sure every detail was handled with care and precision. Both were incredibly knowledgeable, professional, and genuinely kind. They made the process smooth, stress-free, and even enjoyable. It’s rare to find such attentive and thoughtful service these days, and I truly appreciate the extra effort they put into ensuring everything was perfect. I highly recommend this location — and a big thank you again to Tsegab and Wendy for making it such a positive experience! ... Read more

Matt S. - 20 March 2025

This has been one of the most frustrating experiences I’ve encountered. I have rented 2 spaces in this location and 1 of it is on the 3rd floor, and when I arrived to drop off 8 boxes, the elevator was out of service. The storage manager suggested I carry the boxes up the stairs and assured me they would notify me once the elevator was repaired. However, I never received a follow-up call. Four weeks later, after hearing nothing, I returned only to find the same issue. Finally, after 12 days, I received a voicemail stating the elevator was operational. Yet, when I went back, it still wasn’t working. I’ve left multiple voicemails because no one asnwers the calls and since then with no response. This ongoing issue has caused significant delays in my moving process. I need someone to call me ASAP ... Read more

What unit sizes are available at Public Storage - 501 East Diamond Avenue?

This particular storage facility provides self storage units of different sizes, ranging from 25 to 300 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.

What type of storage unit do I need?

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.

Why should I consider renting a climate-controlled unit?

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.
