The process of renting our PortaBoxes
One of our main goals was to make the self storage process as easy as possible for you. Since an easy rental process is a staple of our services, you won’t have to spend your days connecting the dots and figuring out how to get ahold of our solutions. The entire process takes place in a couple of simple steps.
- First and foremost, contact PortaBox Storage to place an order for the number of PortaBoxes you need. Schedule the drop-off date and count on us to arrive with your delivery at the agreed time.
- When we position your Shoreline self storage units, we will leave the property and allow you to pack on your own time. Please take note that our PortaBoxes are at a ground level so you won’t need any special equipment for their packing. In case you need packing materials, such as locks and paper pads, just mention that to our team. We are one of the best suppliers of packing materials so we are fully equipped to provide assistance in this area, as well.
- Once the last of your items are safe inside our PortaBoxes, give us another call to schedule the pick-up date.

The last step is an optional one. You have two options – you can either decide to keep your PortaBoxes on your property or we can place them in our Newcastle, Seattle, or Lynnwood self storage facility. Our warehouses include a fire-alarm system and have no external entry points. There are only two parties who will be able to access our warehouses – our employees and you. Give us a 24-hour notice at any point in time and we will stage everything for your arrival.
Do you need your PortaBoxes shipped to a different location? PortaBox Storage has got you covered!

We will pick up your loaded boxes and drive them to your new home or headquarters.
