You have described what happens when the external seal (between brickwork or stone and window frame) has failed.
How old is the window? Has the stonework been sandblastered? does the silicone sealant pull away easily?
Removing the existing and resealing with a low modulas siicone on a backing rod should prevent water ingress. Around £140 for a standard back to back terrace house.
