Hello
After heavy rain we get water dripping though the tops of window frames.
I think that water is getting through the outside bricks into the cavity, running down the inside of the cavity and seeping though the windows.
Our pointing is not the best and yesterday I patched up the worst of it.
On chipping the loose stuff out I was a bit alarmed by what I saw. Once the hard, brittle pointing is out the remaining mortar is very sandy and soft enough to brush out by hand.
Is it feasible that the water is simply 'soaking through' the wall once it gets behind any cracks in the outer pointing?
Should I be worried about the soft mortar behind, or is it likely to be localised as a result of the poor pointing in that area?
Thanks for any advice.
