Water ingress on bay window - between ground and 1st floor
Posted by Daniel Murphy, on
There has been recurrent water ingress at the top corner of the bay on the ground floor of a double storey bay window. I've had 2 tradesmen attempt to solve the problem by filling in a crack over the window and by repointing the bay . Neither has worked over the past 3-4 years and stain is coming through again in the ground floor bay. Although there is a flat roof on the bay, that is on the upper floor. Looking to get some advice about a possible cause of the problem.
