Depending on the complexity of the model, installing a stairlift can take anywhere between 1 to 6 hours. A rail that fits the length of your stairs will need to be installed, and the technician may already have this prepared beforehand, or arrive with a longer piece of rail which they will cut to fit the measurements.
After the installation has been completed, the technician will show you how to operate your stairlift and the functions of all the different buttons. Always engage a professional to install your stairlift - do not take a risk with an item that can compromise your safety if installed incorrectly.
