Hi everyone - I am new to the forum. We have been renovating an old stone cottage, and the builders we used covered the house with vandex. All has been ok for a couple of years, however following the torrential rain, we have had some ingress of water above the windows (now filled).
Is this problem likely to get worse over time, as I have been told we should have used a breathable lime render (but this is time consuming and expensive to apply, which is maybe why our builder did not use it) I did email our builder, no reply ...
Is the only way round the problem to hack all the render off and re-do?
