wet patches in corners of window when it rains Post questions and find answers on glazing, double glazing, upvc glazing, conservatory glazing, fixtures and fittings etc....

[chris135135]

I have recently had double glazing fitted and have noticed that every time we have heavy driving rain a damp patch appears on the plaster in both bottom corners of the window. The glazier has looked at it and found no obvious gaps. He suggested keeping the windows shut but the rain still comes through.
Can anyone advise me why this should be happening. Should I insist the frame is removed and refitted to check for any faults?

You should certainly tell them you are NOT satisfied and you want it fixed and pronto before the weather gets any worse. How they do it is there problem - if that entails removing the frame completely thats up to them. TBH its not your place to tell them how to do it just that you want it sorted.

The water is comin through the external sill it has not been sealed that's why the water is comin back into the house!!L

The previous poster is correct the water is coming through the cill, however, the cause is probably that the cill is not level or leaning towards the outside as it should be , but leaning inwards
