I can’t say enough good things about this storage facility under the new ownership! The difference is night and day — everything is clean, secure, and so well maintained. The new management team is super friendly, professional, and really goes out of their way to help. ... Read more

Impossible to get ahold of management let alone someone who speaks fluent English in addition to their poor attention to the property they are hiking the rental prices. Don't waste your time at this run down place, its had multiple break ins and absolutely no protection for your belongings. ... Read more
Keely B. - 19 November 2024
The property is accessible always and never closes. It gives me peace of mind knowing that I can have access to my stored belongings or can bring items to store at any time of day for whatever reason. It has a pin code secured gate and security fence as well as cameras. ... Read more

I got an email saying I moved out of my unit when I didn't a month before my actual date, and called to talk to someone and so far I have sat on hold for a half hour waiting to talk to someone. I have a 10×15 storage unit full of everything for a home for my 5 kids and I. Im a single mom. Potentially going to lose all of mine and my kids things ... Read more

I don't know if Security Storage even reads this review. I don't know if their company even exist anymore . I have been trying personally and members of my family have been trying to get in touch with someone from security storage from the past 2 weeks. As of the writing of this review it is June 2nd 2021. I have called their phone number numerous times only to get answering machines. There is no email address that I saw on their website in order to get in touch with them. I've been trying to get in touch with them so I could access my items on their property. Either the gate code has changed are the gate is non-functional. I'm trying to get in touch with them this way hoping that they can actually read this review. But I would suggest not doing business with this company until you can at least get in touch with them. ... Read more

Frequently Asked Questions

There is a wide array of amenities available for the storage units that Security Storage - 3425 Allied Street has to offer. These amenities include 24 hour access, Onsite Manager, Security Camera, Gate, Parking, Online Payment and RV Storage. Most of these amenities can prove to be very useful depending on what you need to store. For example, climate-controlled units can come in handy for keeping sensitive items, drive-up access can make your loading and unloading process easier, and extra security measures will ensure your items are kept safe at all times.

The storage units offered by Security Storage - 3425 Allied Street can satisfy all of your storage needs. Different sizes here range from 50 to 400 square feet. You can go for smaller units if you don't have a lot of items to store, while choosing a larger space is recommended in case you need to store a lot of furniture, bigger items or even vehicles.

The unit size that you should choose obviously depends on how much stuff you need to store. On the one hand, you should think of smaller units (5'x5' or 5'x10') as closets – they can be used to store chairs, lamps, moving boxes and sports equipment, along with smaller pieces of furniture, books and documents.

On the other hand, the 10'x10' and 10'x15' spaces are good for storing larger items of furniture, bicycles and a larger number of possessions. If you need even more space, then 10'x20' and 10'x30' units can easily accommodate the contents of an entire 3- or 4-bedroom house.

Storage units offered by Security Storage - 3425 Allied Street come at a variety of prices, starting from $50 per month for typically smaller units. However, larger spaces can set you back up to $195 a month.

We know that when it comes to self storage, there is nothing more important than quickness and accessibility. Drive-up access is an extremely convenient amenity, as you can park your vehicle right next to your unit, making it significantly easier to load and unload the items you will use storage for. However, drive-up storage units tend to be outdoors, so you might consider indoor storage spaces with climate control if you're looking to keep temperature-sensitive items in peak condition.

Yes, you might, depending on what you need to put in storage. Climate-controlled spaces keep temperatures and humidity levels consistent all the time, which means they are perfect for storing sensitive items. Seeing that a whole host of things can be damaged by varying temperatures and excessive moisture, many people choose to rent climate-controlled units for personal items such as documents, photographs, paintings, collectibles, electronics, wooden furniture, antiques and even vehicles. If you're looking to store such items that are valuable to you, consider renting a climate-controlled unit!
