Shipping Containers – Top Frequently Asked Questions (FAQ) – Part 4
Each week we answer new customer questions about buying, renting, and maintaining shipping containers. In this Part 4 edition of our FAQ series (updated for 2025), we cover lifespan, condensation, insulation, weather-tightness, and container-home use so you can make confident decisions.
16. What is the expected life of a shipping container?
A new one-trip container used for storage can last up to 50 years with proper care. A used container—already having served years at sea—can typically deliver 20–25 additional years after delivery if you maintain the roof coating, door seals, and paint.
- Maximize lifespan with periodic washing and paint touch-ups.
- Keep the roof free of standing water and debris.
- Position the container on a well-drained pad (gravel or concrete).
17. Is condensation a problem in shipping containers?
Condensation forms when warm, moist air contacts cool steel. It’s more likely if the container sits on damp ground, has roof dents that hold water, or is poorly ventilated.
How to reduce condensation
- Elevate the container on gravel or concrete to reduce ground moisture.
- Ventilate on dry days (open doors, add vents as needed).
- Store goods that are dry and consider moisture absorbers for sensitive items.
18. Can a shipping container be insulated?
Yes. You can use factory-insulated reefer containers for temperature-controlled storage, or add insulation (spray foam, rigid board, panels) during a modification. For residential or office use, always consult local building codes and a qualified contractor.
19. Are shipping containers weatherproof?
Containers graded Wind and Water Tight (WWT) are effectively weatherproof for storage and general use. Avoid “As-Is” units unless you’re prepared for potential repairs (holes, delamination, damaged seals, bent bars).
20. Can a shipping container be used to build a house or an office?
Absolutely. Container architecture continues to grow for homes, offices, retail and hospitality. Containers are strong, modular, and can be stacked or combined to create larger footprints. Work with experienced fabricators and ensure all modifications meet code.
