How to Rent, Buy or Modify

1. Consult with a Container Sales Expert

Your first essential step is to have a conversation with a sales representative. They’ll guide you through the process and can provide you with a quote. Their expertise allows them to assess your specific needs and recommend the ideal container size and type tailored to you.

2. Prepare the Container Site

Once you’ve settled on the perfect container, it’s time to prepare its designated location. This preparation might involve clearing the area, ensuring a level surface and confirming that our delivery truck can access your preferred location. A properly prepared site ensures the safe and stable placement of your container, smoothing the delivery process.

3. Receiving Your Storage Container

After completing all the necessary preparations, it’s time to receive your storage container. We try to provide advanced notice before delivery, helping you plan around our delivery.

Whether you choose to buy or rent, these steps will ensure a smooth and efficient process, ultimately providing you with the convenience and peace of mind that accompanies hassle-free storage.

Touring the Container Yard

At Southwest Mobile Storage in Phoenix, Arizona, we understand that buying a container sight unseen can be difficult, or even dangerous. Some organizations list containers available for sale on sites like eBay or Facebook Marketplace, while they’re selling nothing more than false promises. These scammers can take your hard-earned money, so we advise coming down to our office and looking at our containers in person before making a decision.

Give us a heads-up so we can greet you appropriately, and our experienced container sales representatives will be happy to show you around.
