We operate a self storage facility in Helena, Montana, serving customers from Helena, East Helena, downtown Helena, and surrounding areas. Our location at 3425 Allied Drive, near Highway 12 between downtown Helena and East Helena, provides convenient access to storage units and vehicle parking. Customers can rent spaces in different sizes according to what they need to store, including personal belongings, boxes, seasonal decorations, sports equipment, furniture, appliances, business materials, equipment, and larger household contents. Our drive-up units allow renters to bring a vehicle directly to the unit entrance, reducing the effort required to move stored items. We also offer RV and boat storage, with both covered and uncovered options available depending on current inventory. Month-to-month rentals give customers a flexible way to manage storage for moves, home projects, seasonal changes, and business use.

The facility is accessible daily from 7:00 AM to 10:00 PM and uses keypad entry to help manage access. Fencing, gated entry, security cameras, and 24-hour video monitoring are included as part of the facility's security features. Customers can manage payments online and rent available units through the website. Our storage options are intended to provide practical space when belongings, equipment, vehicles, RVs, or boats require a dedicated location outside the home, garage, driveway, or workplace. To determine which unit or parking option is currently available, customers can check online or contact us directly at (406) 227-6652.

Self Storage Our self storage service is designed for homeowners and renters seeking additional room for furniture, seasonal decorations, sports equipment, and household possessions. When these belongings can no longer fit comfortably in closets or garages, a storage unit provides an organized place for them while allowing more space to remain available throughout the home.
RV & Boat Storage We provide covered and uncovered outdoor parking for RVs, boats, campers, and trailers at our fenced and gated facility. Keypad access, security cameras, and daily access from 7:00 AM to 10:00 PM support convenient vehicle storage.

Havent had any issues since I started using a rental unit several months ago. Units are clean and accessible and management is always easy to communicate with.

Really no complaints. I've been renting off and on from security storage for years and always have found them easy to deal with. Their prices are reasonable and the place is well taken care of. They have security cameras all over the place so I feel like my possessions are secure. I would advise anyone to use this facility.

These guys have been amazing for me since 2019. No muss, no fuss, and they worked with me when I lost my job and was behind on payments for a month. Really great local folks who love Montana and the Helena community.

This facility provides excellent value and is remarkably easy to use, making it the perfect arrangement for my needs. The new ownership is highly responsive and accessible, and the manager, Tyler, was a pleasure to speak with.

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.

After another storage place in town tried to over charge me, security storage's reasonable rates and excellent customer service were like a breath of fresh air
