You should change the seals periodically when you clean the windows or paint the windowsills, during summer or early in the fall. Many people tend to leave weatherproofing too late in fall or winter when they notice a draft and cold from the windows. But this affects the quality of the work.

It matters where you attach your seals

Correctly weatherproofed windows, doors and their joints reduce the feeling of draft and so reduce the energy spent on heating the apartment.

Their correct maintenance also affects living comfort and saves money when you won't have to change the whole window. Correctly maintained frames also help when attaching the weatherstrips, which may detach from dirty or extremely curvy frames.
