Water from behind Mastic

[newts]

Op has confirmed its a timber framed building which I confirmed from the picture.

Ground floor outer skin is stone work and the first floor outer skin is Cement board with a K rend

If weep vents where needed LABC would of specified them which is part of the 25yr certificate

Op needs to contact LABC to try and solve the issue.

What's the outer leaf actually made of? (blocks, bricks or something else) Are there any cavity vents?

Brick with timber frame. It has a membrane which cannot be punctured from inside otherwise it effects integrity of the house.....so they say.

It would appear from post above that it's brick outer leaf?

Logged a case with them on 26th Feb but they haven’t even started to review it yet. The K rend extends down to ground floor window and under lintel

From a builders point of view I would wait for LABC to investigate the issue.

I have only had dealings with NHBC which I have found to good in the past.

I wish you luck and hope you get it resolved.
