What Our Clients Say


This comany provided exemplary service during our move. Not one thing was broken. Smaller crates allow to lift straight up with a forklift, so the crates are never tilted to the side. We did not realize the previous homeowner still had a car in the garage when we had our crates delivered and the driver was immediately available to move a crate and create access. Highly recommended!

Cindy Wynette


They are great! Excellent service. Affordable, And flexible. Awesome!

Sarah Sacry

Have had a big portion of my belongings packed up for months during a remodel. Needed some things from my portaboxes midway and they made it really easy for me to go down and go through my containers. Very happy.

Don Van Boerum

Great local company with personal feel to every interaction. Best price around. Easy to work with. The smaller containers where much easier to work with and loved the option to take back any we didn’t use without charge. Took the pressure off. Overall great experience.

Berkeley Shepherd

Portabox was stellar! They stored my items for two years and upon unpacking everything was in working order and exactly the way I’d left it (including my TV!). Their drop off and pick up service was easy and convenient as well! Love them, would highly recommend!!

Heather Boatwright

Great service, great container equipment. Setting up the rental was quick and easy. The storage container was weather-proof, and had no problems for the winter months that we had it. The cost to have the container right next to our back door was similar to having an off-site, remote storage unit, but without the inconvenience. The office staff, and the delivery and pick-up drivers were awesome, and were very professional. The drivers notified us in advance of their ETA, and were careful positioning the unit in our narrow driveway. I highly recommend PortaBox Storage.

Bob Duffin

Great company with honest, helpful folks and the best prices I could find in town. We rented 7 portabox units to hold most of our household items for 6 months in between moves. All belongings were safe and damage free. Delivery of the units right to our driveway was incredibly convenient. Everything from scheduling the loading to accessing the units while in storage to drop off of the units at our new home and subsequent pick up of the crates was extremely smooth and on schedule. No regrets and highly recommended.

Jon Grant

Very professional, timely and helpful. We needed to be out of the home we sold one week before we could move into our new home, and this solution beat renting moving trucks, storage units, etc. I will highly recommend PortaBox Storage to anyone similarly situated. We had no damage to the contents of the PortaBoxes other than what we may have caused ourselves in loading/unloading.
