Hi, everything in our house was re-done so new floors/walls throughout. We have a new tiled hallway you can see in the picture, the wall is a brick wall which was PVA'd and new plasterboard/skimmed and with new skirting. As you can see from picture there is a layer of damp that has appeared (on this internal wall) with a little patch on the other side of wall (in living room). Is this to do with the weather as it's been so hot and just a couple of days of damp weather brang it out or maybe not having the heating on for a couple of months now? Anyway I'm planning to remove skirting, cut out the damp strip, put a membrane against the brick wall and re-attach new plasterboard and get it skimmed and then re-apply skirting. Any advice or alternative? Hoping it doesnt appear anywhere else on the ground floor!

Radiator is on other side of wall, pipes from this go below floor boards in living room. There used to be the main water pipe coming in under the floor but this burst (probably 20 or more years ago now) so the pipe now comes in and is fed up and through the ceiling of the ground floor towards boiler in bathroom. Potentially water from old burst pipe causing damp?
A long shot, but? there are a couple of Ifs
Is the affected wall plasterboard?
if it is plasterboard, does it have a Foil backing?
If yes to both above, then there is a Possibility of Condensation forming on the rear foil face of the plasterboard and running down to cause the damp line.
Another possible cause is that the plasterboard is touching the Concrete Floor behind the Skirting and is being affected by dampness on the Concrete, if the floor is indeed Concrete?

It looks like rising damp - is there a DPC in that wall?
Are the floors on either side of the wall solid or suspended?
If either floor is solid is there a membrane below the solid concrete?
Moisture that cannot evaporate thro the tiled floor might find its way to rising up the nearest DPC free wall - only a possibility.
If i understand: you PVA'ed a bare brick wall in the hall
then you fixed plaster board -How, by dot and dab?
then you skimmed the p/b?
What you propose might simply shift the damp tide mark higher up the wall.
Why not carefully check all the house walls for signs of damp?
