Drying out wet patches in wall

[nicknoal]

Hi all,

I recently had a problem with my roof and gutters that were leaking water into my house and has caused the below water marks in one of the bedrooms.
The gutters and roof have now been fully replaced and so the main problem has been resolved.
However I’d like to know what would be the best way to dry out and deal with these water marks that have been left behind?

I expect I’ll have to re-wallpaper the walls, but what about the plaster above the picture rail? How would it be best to try this out?



Much appreciated!

Remove wallpaper to speed drying , but will take weeks/months or more to dry completely depending on how severe the leak.

Thanks for the advice

If I managed to balance a fan heater at that height and faced it at the damp area, would it speed up the process?

No radiator in room?

Dehumidifier?

Would be if ( marginal) help with surface damp but not deep in brickwork.

We spent many years sub contracting to a specialist insurance contractor.
Standard practice is industrial dehumidifier plus large fans to keep air movement.

Yes this was my initial thoughts but I was hoping to save on the cost of the dehumidifier

But I suppose you make a good point that the damp would also be in the brickwork and not just the surface plaster

Would a Dehumidifier be best recommended to cure the issue then?

I doubt your situation calls for a dehumidifier as it removes moisture from the air. You don’t seem to have a lot of damp so won’t be a lot of damp air .

By way of an update I took the first layer of wallpaper off last night as per your advice which uncovered some significant mould. The interesting thing is though that the mould only appears to be on the remains of the wallpaper and the plaster behind seems to be dry.
So Im hoping that when I remove the remaining wallpaper the bulk of the mould will be gone.

I’ve also had a bed in here for around 2 months and when I moved the bed there was even worse mould that only went up to the level of the mattress.

Do you know what will have been causing this mould around where the bed was? I assume it would have been due to a lack of air flow but it seems a lot from only 2 months?

Yes lack of ventilation , damp walls.
