Leaks Around Window

[tooj]

Whenever it rains heavily damp a;pears around the double glazed window over our stairs.
We have had it resealed professionly more than once but after a coiple of storms it leaks again, the paper around t gets soaked and a towel on the sill
needs wringing out. We can't see where its coming in. We asked our insurers and theydon't
want to know saying is wear and tear. The local window people don't know whats causing it.
It has been suggested that its coming through the brickwork but we can't see anything nd we don't know any reliable builders to ask. Anybody any suggestions what we should do next
please.

[The Builder]

I just thought I'd mention that 60 years is most likely before many of the steel lintels shown in my link above were available.

Certainly before combined lintels were around. Probably two pre-cast concrete lintels, one for each leaf.
The tray would then be old-style bitumen felt . This gets quite brittle with age, and deteriorates easily.

Let's see anyway.
