For many homeowners and businesses in the Pacific Northwest, the rainy season poses storage challenges. Moisture, humidity, and runoff can damage belongings if storage containers are not prepared correctly. Whether you rent or purchase a container from NWR Storage Containers, taking a few preparation steps ensures your items stay safe and dry.

Why Rainy Weather Matters for Containers

Even though storage containers are constructed to be airtight and weatherproof, ensuring proper placement and preparation enhances performance in wet conditions. This matters especially for long-term storage of belongings such as furniture, equipment, fabrics, and tools.

Choose the Right Site

The first step is proper site selection:

• Level the ground:Standing water can pool on uneven ground and find its way into bottoms or door seams.
• Ensure drainage:A slight grade away from the container helps water flow outward rather than toward the container’s base.
• Avoid flood paths:Be mindful of gutter runoff or natural drainage routes that could channel water toward your container.

Elevate the Base

If your site is expected to stay wet for long periods, consider placing the container on wood blocks, gravel, or a compacted stone base. These supports:

• Keep the container off soil that may retain water.
• Reduce corrosion risk at the base.
• Improve airflow underneath.

NWR often recommends wood blocks for surface protection and stability.

Seal Doors and Gaps

Check door seals and weatherstripping before storing valuable items:

• Wipe or replace worn rubber seals around container doors.
• Inspect for dents or misaligned doors that might allow water intrusion.
• Use a container with a custom lockbox system(offered by NWR on many units) for enhanced security and seal protection.

Interior Precautions for Moisture Control

Even in a tightly sealed unit, moisture can build inside due to condensation — especially when temperatures change frequently during the transition seasons.

To mitigate interior moisture:

• Use pallets or shelving to lift items off the floor.
• Place desiccants or moisture absorbers in the container.
• Allow airflow periodically by slightly opening doors on dry days (if contents are secure).

Packing Tips for Rainy Season

• Wrap furniture and fabric itemsin breathable covers.
• Use plastic binswith tight lids for smaller items.
• Label everything clearlyso you can access boxes without unpacking the entire container.

Routine Checks During the Rain

Even after preparation, it’s smart to:

• Inspect the container after heavy storms.
• Look for standing water or damp spots near doors.
• Adjust positioning or add drainage solutions if necessary.

Common Rain-Related Mistakes

• Placing containers in low spotswhere water pools.
• Packing items directly on the floorwithout elevation.
• Assuming airtight equals moisture-proof:Airtight containers still need airflow and internal moisture control.

Preparing your storage container for the rainy season protects your belongings and extends the life of your unit. With proper site selection, elevation, sealing, and moisture management, a container from NWR Storage Containers can remain a safe, dry storage solution even in wet climates.
