Damp ingress after repointing.

[Johnykp]

Hi,
We recently had our 1888 built house re-pointed, the wrong pointing(cement) was already there when we bought the house, we were seeing a number of damp areas appear, so we go our builder to pick it all out and re-pointed it with lime. He showed us a few areas that the old cement pointing had fallen out etc.

He finished the new pointing about 6 months ago. However we have noticed some damp coming through on the gable end on 2 levels. Now, the cable end went quite a few months being exposed between the picking and pointing( the builder was doing it all himself and had other jobs on the go) so it was open to the elements. Any ideas what could cause this?

He's a highly regarded builder and did the front of our house pointing 2 years ago with no issues, he used the correct materials aswell. My thought is could be left over moisture from when the cable was exposed and these points are where it's 'escaping'?

We have also had a massive downpour of snow and the resulting melting.

The builder thinks ventilation may be causing it?

The areas in green are roughly where the dampness is on the inside.

Thanks

Your builder appears to have done a decent job too so not a pointing issue. Parapet walls however, are the work of the devil.

You can treat wall with storm dry as that may help.

What's on top of the chimney, is it in use/ capped off etc?
