Hi all. Looking for advice please...
Builders just completed a rear extension - block built cavity wall. They dot and dabbed standard plasterboard (paper backed) to all the walls in this area before the rear French doors were installed. The sides of the head and reveals were protected with plastic sheeting, but that's about it. The house is undergoing major renovations and has no heating currently. It was a wet period when this was done (a few weeks ago now).
After the doors were fitted, we returned to the house about a week later and noticed damp spots where the dabs had starting to leach through, all of which had black mould spots dotted across the surface. This was about 2 weeks ago.
We cleaned off the mould as best we could with an Anti-mould spray and damp sponge, and put a dehumidifier in the room plus a small convector heater. This seemed to keep the worst of the mould at bay over the weekend when we could be in the house running the heater and dehumidifier. But over the week when it's unoccupied, the mould returns. Not as bad as it was, but definitely coming back.
The builder claims this is entirely normal and admits no liability. That we should keep heating/dehumidifying and just carry on wiping any mould away as it appears until it's all dried out. Since some of the mould is ingrained into the board and doesn't wipe off (faint admittedly), that's not exactly plausible.
So... is our builder correct? Will I be wasting money in getting skimmed now if there's an inherent problem that won't go away with mould growth?
