FAQ — container modification

- Cost depends on scope (cutting, insulation, mechanical), container size and transport. Request a free detailed estimate with line items and options.
- Can a container be modified for the Quebec climate?
- Yes. Insulation, thermal bridges, ventilation and openings are designed for harsh winters and temperature swings.
