A storage container is more than a passive shell—it’s a protective environment for your belongings, tools, equipment, or workspace. Like any structure, it benefits from periodic maintenance to prevent damage and prolong service life. Here are some actionable tips and best practices for maintaining your container and protecting what’s inside.

1. Routine Inspections

• Perform visual checks every few months (or more often in harsh weather).
• Examine roof, walls, seams, corners, and undercarriage for rust, dents, cracks, or signs of stress.
• Inspect welds, seams, and door edges for separation or weathering.
• Watch for signs of moisture, mold, leaks, or water intrusion.

2. Roof & Drainage Care

• Keep the roof clean—remove debris (leaves, branches, snow) that can cause pooling or extra weight.
• Repair dents or indentations that hold water. Even small “dimples” accumulate moisture and speed corrosion.
• Check roof end caps and gutters (if installed) to ensure water sheds correctly.

3. Door, Hinges & Seal Maintenance

• Clean door gaskets and seals to remove dirt, grit, or debris that can wear down rubber.
• Apply lubricant (e.g. a silicone-based lubricant) to hinge pins, locking rods, and sliding components to prevent rust and stiffness.
• Test door alignment—if doors bind or sag, correct the alignment before seal damage worsens.
• Replace any torn or cracked rubber seals or gaskets early to prevent leaks.

4. Rust & Corrosion Management

• Where paint is chipped or edges are bare, sand lightly, prime, and repaint to isolate bare steel.
• Use rust-inhibitive primer or coating in touch-up areas.
• Keep base plates, corner posts, and threshold zones clear of contact with soil or vegetation to reduce galvanic corrosion.
• Avoid direct soil contact by elevating container slightly using blocks or piers.

5. Interior & Floor Care

• Keep interior dry and ventilated; avoid trapping moisture under stored materials.
• Use pallets or raised shelving to prevent wood-to-steel contact that holds dampness.
• If floorboards (marine-grade plywood) are damaged or weak, patch or replace locally before you risk structural issues.
• Clean spills or chemicals promptly—some substances degrade flooring or coatings.

6. Ventilation & Moisture Control

• Good airflow helps reduce condensation, which can lead to interior rust or damp damage.
• If using the container long-term, consider installing passive vents or desiccants to reduce humidity.
• Monitor for water infiltration after rain or storms; address leaks quickly.

7. Seasonal & Preventive Tasks

• Before winter or rainy seasons, review doors, seals, flashings, and patch any suspect wear.
• After storms or snow events, check roof and walls for new damage or bearing stress.
• Lubricate hinges and locking mechanisms annually (or more in heavy use).
• Wash exterior occasionally to remove salt, grime, or pollutants that accelerate corrosion.

8. Addressing Damage Early

• Small dents or surface rust spots are easier to fix early—delay invites deeper damage.
• For larger damage (bent panels, structural compromise), consult a qualified technician or container specialist.
• Document repairs and keep logs to track maintenance history.

Why Maintenance Matters

Regular upkeep increases your container’s lifespan, preserves warranty conditions, and keeps your stored goods safe from weather, pests, or structural failure. For container owners, it’s a way to protect your investment. For renters from NWR, it helps avoid damage or extra fees at return.

Whether you rent or own, caring for your container is critical. Rest assured our fleet is maintained to high standards—your additional upkeep will help extend their life and protect your contents.
