Absolutely amazing place! Michael was an amazing and even was able to get me a prorated refund! Wasn’t expecting it but it was a wonderful surprise!

Zach was great today. He’s really helpful and easy to talk to. Management is lucky to have him as an employee. His customer service skills are top notch.

Dawn was wonderful to work with! She was extremely helpful and kind as she showed me units and explained the process. I would absolutely recommend her and Guardian Storage!

The property manager, Tea, was outstanding! A lot of these storage facilities seem a bit shady to me… But Tea felt very honest, helpful, and warm. He went the the extra mile when he noticed on the security cameras that I got lost and instead of going home, because it was after hours, he found me and brought me to the correct unit. The facility itself is very clean and feels secure. I highly recommend.

Dawn was amazing and very helpful! Helped me get everything I possibly needed and made me feel very good about keeping my stuff at this establishment!

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

The staff was friendly, knowledgeable, and made the entire process easy from start to finish. I appreciated how straightforward the pricing was and how accessible my unit is whenever I need it. I feel confident storing my belongings here and would definitely recommend this storage business to anyone looking for a reliable and hassle-free option.

The manager James was very helpful and very thorough. I would recommend this facility to friends and family

Very clean facility. Staff was helpful and friendly. They went out of their way to accommodate my needs. Thank you for all of your help

Guardian Storage was incredibly accommodating during our time of need. We were preparing to move out of the Pittsburgh area for a short period to get additional support for our growing family, and having access to an on‑site truck made moving in so much easier. The staff was helpful, flexible, and attentive to every question and request we had.

Move‑out was just as seamless. Conversations about dates and timing were simple, and the entire process felt organized and stress‑free. We truly appreciated the level of service and support we received.

Highly recommend.
