When it comes to transporting modular homes over long distances, maritime freight offers a reliable, efficient, and scalable solution. At SeaTac Marine, we specialize in moving modular buildings safely and cost-effectively between Washington and Alaska, using decades of experience with shipping from Seattle to Alaska and complex cargo logistics.
Whether you're a project manager, homebuilder, or government agency planning a modular deployment, you likely have questions about how freight shipping works for modular units. Below, our team answers the most frequently asked questions to help you navigate the process with confidence.
SeaTac Marine is equipped to handle a wide range of modular structures, including:
We’ve successfully moved single-wide and double-wide modular units, as well as custom-built configurations, all tailored to the needs of Alaskan communities and industries.
Proper preparation is key to protecting your modular home for ocean shipping. Modular homes are inspected, sealed, and often shrink-wrapped or otherwise weatherproofed before loading. SeaTac Marine Service’s marine terminal services include staging and securing the units at our Seattle location before they're loaded onto our barge.
We also coordinate with overland carriers on both ends to ensure seamless handoff and minimize delays.
Our marine terminal is equipped with high-capacity forklifts, cranes, and roll-on/roll-off (Ro-Ro) capabilities designed specifically to handle modular freight and oversized and heavy cargo. The method used depends on the size and construction of your modular home, as well as the vessel type.
SeaTac Marine’s experience with Washington to Alaska cargo shipping ensures your structure is moved using the most secure and efficient method available.
