    Hi all

    Recently moved into a new property (1960) semi detached house with no issues until we started painting and noticed a small area of ?damp (I’m a total diy novice) which had peeling/ flakey paint so we covered the area with damp seal which lasted about 3 weeks until it bubbled. What should we do ? I’ve took the damp seal off and sanded the area.

    Can you also post a picture of the outside area.

    From the photo it is not very clear to see any damp, is there a musty smell present, the outside porch wall may be a clue, have you checked the condition of the porch flat roof etc?

    No musty smell but before I put the damp seal on the area was flakey and efflorescence coming through. Below links are after I put it on and after 3 weeks scrapped bubbles off

    Is the pillar supporting the front porch roof actually tied in to the main wall (ie do its bricks go into the wall) or is it just
    resting against the wall?

    If it's not tied in, I'd suspect rain water is being trapped between the pillar and the wall and coming through into the hallway.
    Re-pointing should sort it out, unless the leak is from the porch roof.
