The cost to add a roll-up door depends on opening size, container height, framing, seals, installation location and optional power. As a Canadian example observed September 13, 2026, PortableStorage.ca advertises a steel-slat roll-up door at $1,800 including installation at its site. The page does not publish the door size or a complete list of inclusions, so this is not a Canada-wide average or a quote for a particular project; confirm the door, frame, transport, tax, permits, electrical work, structural design and site work in writing.

Normalize roll-up door quotes before comparing them
Door size changes more than material quantity
Shop installation and field installation are different jobs
Electrical operation creates a second scope
Use a quote-validity checkpoint
Turn advertised prices into the same project scope
Provide the finished opening, container type, wall location and address. Ask each supplier to separate the door, frame, installation, seals, security, power, transport, tax and professional or permit costs.
