Installing a Retrofit Elevator – A Step-By-Step Guide

We’ll plan and coordinate the entire retrofit elevator installation process, and a dedicated project manager will make sure that everything is completed on time and on budget.


We can help you gather information about suitable solutions for putting a retrofit home elevator in your building, as well as permits and subsidies, and make a rough cost calculation.


We can discuss your options for financing the project, help to identify how much might be covered by subsidies, and recommend alternatives for sharing the costs amongst residents.


We’ll determine the installation location of your retrofit elevator, create the architectural and engineering designs for the shaft, design the retrofit elevator cab interior, and make sure that all relevant permits have been processed.


We take care of all the necessary site preparations, the shaft and retrofit installation, and the final cleanup. Before we hand over your elevator, we’ll carry out a full lift safety and performance inspection.


Our total preventive maintenance services keep your elevator running reliably for its entire lifespan. If problems do occur, our skilled local lift technicians will get the elevator up and running again as quickly as possible.

The Right Elevator for Your Building - Let’s Make It Happen!



We can install an elevator in almost any building. The size and shape of your stairwell will determine whether the elevator will be installed inside or outside.

Installation options:

  • Inside the stairwell with the stairs on either side

  • In the middle of the staircase

  • Partly replacing the staircase, which is extended outside the building

  • In a pre-assembled shaft on an exterior wall; because the shaft is pre-assembled then lifted into place to save time and money.



We can create a solution that matches the interior design and architecture of any building. You can choose an elevator shaft material that matches both your building’s interior and the car wall and floor materials.
