elevator installation
A contractor that installs elevators during construction, replacement, or additions to an existing building.
An elevator installation company is a contractor responsible for installing elevators in a building, either at the initial construction stage, when replacing older elevators, or when adding new elevators to an existing building.
The work can establish the first elevators in a new building or change elevator provision in an existing one. Replacement and addition are both included, rather than limiting the role to original construction.
An elevator manufacturer supplies the major hardware. Installation concerns fitting the elevator in the building, while elevator finishing concerns paneling, doors, ceilings, and custom finishes.
