List of Top Storage Container Rental Companies in Washington

  1. Jump Box Mobile Storage

    Our Score:4.8 / 5
    • Verified
    • Local
    • Est. 2022

    Jump Box Mobile Storage belongs to the National Portable Storage Association. Few independent container companies in the region hold that membership. That standard shows up in how they run. They post rental pricing openly online and let you book a container without a phone call. Their drivers place units with a remote-control power unit that fits driveways and side yards most delivery trucks cannot reach. Few local operators run yards in as many Washington markets, from Puget Sound to the Spokane area and the Tri-Cities, so a container is rarely far from your site.

  2. Tri-Cities Mobile Storage

    Visit Website Pasco, WA

    Tri-Cities Mobile Storage has rented mobile units across the Pasco, Kennewick, and Richland area for more than twenty-five years. No other portable storage company working that market has lasted as long. Length of time matters here because projects rarely end on schedule. Reviewers describe renting a single unit for a quick remodel and others keeping one for years through stop-and-start construction, with the same family answering the phone the whole way. If your timeline is uncertain, that flexibility is worth more than a slightly lower monthly rate that comes with a rigid contract.

  1. Swiftbox Portable Storage

    Visit Website Snohomish, WA

    Swiftbox Portable Storage gives customers a choice most container companies do not. You can keep your loaded container parked at home, or have Swiftbox haul it to their guarded yard in Snohomish and still drop by for your things whenever you want, at no extra charge. That second option is rare among local providers. It suits a renovation or a flooded house, where rooms have to be cleared but the contents need to stay close. Owner Mike and his crew are known for sliding containers down steep and narrow driveways that defeat larger trucks.

  2. NWR Container Rentals, Inc.

    Our Score:4.4 / 5
    • Verified
    • Local
    • Est. 1991
    Visit Website Bellingham, WA

    NWR Container Rentals rents steel road plates, not only storage units and job-shack offices. Those plates are the heavy steel sheets that bridge open trenches and protect roadbeds during utility work, and almost no other container yard in the area stocks them. So a contractor can make one call for both a locked container and plate to cover an excavation. The family behind it has rented across Whatcom and Skagit counties since 1991. No other container outfit up here has been at it as long. It is a practical fit for site crews juggling storage and ground protection at once.

  3. Conseal Containers, LLC

    Our Score:4.3 / 5
    • Verified
    • Local
    • Est. 2003
    Visit Website Spokane, WA

    Conseal Containers keeps customers for fifteen years and longer. Several Spokane-area companies in its reviews call it back season after season for the same job sites. Few rental yards hold that kind of loyalty. It usually means the delivery shows up when promised and the driver can set a container neatly on a tight or cluttered site. Conseal has rented and sold cargo containers across the Inland Northwest for more than two decades, so it knows the region's harder-to-reach yards well.

  4. BlueBox Storage

    Our Score:4.0 / 5
    • Verified

    • Est. 2020
    Visit Website Vancouver, WA

    BlueBox Storage backs its containers with a layer of security that smaller providers rarely offer. Store your loaded container at their Vancouver yard and it sits behind a gated entrance under round-the-clock cameras, not on an open lot. For belongings you cannot replace, that monitoring changes the math. BlueBox pairs that yard with flat pricing and no add-on fees buried in the contract. Across southwest Washington's storage market, a quote that holds firm from first call to final pickup is harder to find than it should be.

  5. Whisman Storage Cargo Containers

    Our Score:3.9 / 5
    • Verified
    • Local
    • Est. 1993
    Visit Website Deer Park, WA

    Whisman Storage Cargo Containers reaches properties that stop other delivery trucks cold. Based north of Spokane in Deer Park, the company is set up to haul cargo containers down long gravel drives and out to rural acreage where access gets tricky. If your land sits well off the paved road, that capability matters more than a low quote you cannot actually use. Whisman has rented and sold containers across the Inland Northwest for more than thirty years. That is one of the longer runs in the regional market. Free delivery reaches select nearby areas and trims the cost on closer sites.
