A curved track stairlift is the most expensive of the stairlift options. This is because the track has to be tailor made to your stairs. The cost is worked out on the length of the track and the number of bends. A specialist survey is required to ensure that the measurements are taken correctly. The stairlift can be fitted on either the inside or the outside of the stairs, depending on the layout of your staircase.
A deposit is taken when a curved stairlift is ordered as the manufacturers are building a track specific to your stairs. The balance is paid when the installation is complete.
