Hands down best storage unit facility in the area. Customer service is top notch always friendly and helpful.

If you’re looking for secure, reliable storage in the Boulder, Superior, Lafayette, Louisville, or Broomfield area, stop scrolling. Guardian Storage in Superior is it.

I’ve used storage units in half a dozen states, and nothing has come close to the experience I’ve had here. It’s clean. It’s safe. It’s actually affordable. But what really makes this place shine is the people. Especially Sam.

Sam is the kind of guy you want on your team when you’re juggling a move, navigating a life pivot, or just trying to keep your stuff from becoming someone else’s problem. He’s sharp, down-to-earth, genuinely funny, and totally on point. You can tell he’s done this before. He brings real knowledge and calm energy to the chaos that usually comes with moving.

Each time I came in, whether I was a mess or just needed a quick question answered, Sam treated me with respect, professionalism, and kindness. He makes the process feel easy. His coworkers were also friendly, present, and ready to help. Shoutout to the whole team for being solid humans.

And let’s talk about the business center for a second. It’s actually useful. Fast Wi-Fi, comfortable seating, and amenities you don’t expect at a storage place. I’ve even worked remotely from there mid-move. It’s that good.

Bottom line: If you need a top-rated, climate-controlled, secure storage unit near Boulder or Broomfield that’s well-run and staffed by genuinely helpful people, Guardian Storage in Superior is hands down the best self-storage experience I’ve had in Colorado. Whether you’re downsizing, moving, or just need extra space, this place delivers. Ask for Sam. You’ll walk away impressed

Was wonderful in helping me get a storage unit, easy, quick and fast. Thank you so much!!! I will keep coming back here.

Absolutely amazing! The property manager Tioni was friendly and helpful upon my arrival. This location is very clean and the amenities are great! I will be back! Thank you Tioni and Guardian for fantastic service! 😊

I was hesitant to rent a storage unit. Kenzie came highly recommended at Guardian Storage in Frederick, my experience has been very professional and pleasant. I would strongly recommend Guardian Storage. THANKS Kenzie

Spotless, secure facility and always friendly professional service. Been leasing here for almost 3 years and never an issue. Special thanks to Property Manager Tioni!

Dave is always very helpful and goes out his way to outstanding customer service. I am a long time customer and it is because of employees like Dave that I enjoy being a customer and recommend Guardian Storage to my family and friends.

Master class in Customer Service!
I filled out the interest form at about 2am.

I got a call about 9am.
I politely asked them to call me back in an hour and they did.

They answered all my questions and calculated my price for the time I needed to use the facility.

I went and toured the facility, EXTREMELY clean, great lighting and just an overall positive feel.

I told them that I actually booked a storage company before I found them and that I would go see that place and comeback if I didn’t like the other place.

Needless to say that I came back and I am happy that I did!

It cost only little more than the other storage place but the price difference was nothing when comparing the two locations and the customer service was PHENOMENAL!!!

I have been using Guardian storage on and off for years. Always great customer service and the management is hands on with making sure all my needs are met for any situation. Thank you for delivering me a safe carefree place to store all of my important items.

This is by far the best and cleanest storage place I’ve ever been. Highly recommended. John, the manager is attentive and responsive
