What does wind and watertight mean for shipping containers?
Wind and watertight means a shipping container is fully sealed against rain and draughts. The doors close properly, the roof, walls and floor have no holes, and water cannot enter under normal weather conditions. A wind and watertight container protects stored goods from the UK climate but is not guaranteed to be airtight or brand new.
What “Wind and Watertight” Actually Means
When you see wind and watertight listed on new and used shipping containers, it refers to the container’s ability to keep out the elements, not its cosmetic condition.
A wind and watertight container will:
- Have solid steel walls, roof and doors with no daylight visible inside
- Close securely with working door seals and locking bars
- Prevent rain, surface water and wind-driven moisture from entering
Scratches, dents and surface rust are normal, especially on cheap shipping containers UK buyers often choose for storage. These do not affect the wind and watertight rating as long as the structure remains sealed.
Why Wind and Watertight Matters for Buyers
For most UK buyers, wind and watertight is the minimum acceptable standard when buying shipping containers for sale UK-wide.
It matters because it solves real storage problems:
- Protects tools, stock and equipment from rain and damp
- Provides reliable secure storage in all seasons
- Performs well in exposed UK sites like farms, yards and construction projects
- Keeps contents dry without the cost of a brand-new container
If you are using containers for long-term storage, container hire, or basic workshops, wind and watertight is usually all you need, paired with anti condensation methods, these units are perfect for affordable, reliable storage.
Wind and Watertight vs New “One Trip” Containers
Many customers ask whether wind and watertight is the same as new. It is not.
Here is the key difference:
- Wind and watertight containers are used units that remain structurally sound
- New one trip containers have typically made one sea journey and are close to showroom condition
Both can be ISO-certified and suitable for storage, but used wind and watertight containers offer much better value if appearance is not critical.
What Wind and Watertight Does Not Mean
It is just as important to understand the limits.
Wind and watertight does not mean:
- Airtight or humidity-controlled
- Condensation-free without ventilation
- Guaranteed rust-free
- Fully refurbished
Condensation is a common issue in steel storage containers, especially when warm air meets cold steel. This is normal and can be managed with vents, airflow and good storage practices. – See Our Guide On the Top 5 Natural Ways On How To Control Condensation In A Shipping Container
How Wind and Watertight Containers Are Checked
Reputable suppliers inspect containers before sale.
A proper wind and watertight check includes:

- Door operation and seal condition check
- Roof integrity inspection, especially for pinholes
- Internal light test to detect daylight ingress
At Bosh Boxes, every container is checked before container delivery UK-wide, so buyers know exactly what they are getting.
