The capitals can definitely be applied subsequently. They are also applied by the window manufacturer. However, there is a difference whether this is done in a workshop or in the installed state in your house. The window profile is degreased with PVC cleaner or the surface is slightly removed and the capital is glued on. This is much faster in the workshop than at the construction site, i.e. it will certainly be much more expensive. If in doubt, ask your window manufacturer if this will be more expensive, and if so, how much.
