Remove plaster to allow bricks to dry out?

    Hi, in a room below a troublesome valley gutter which has leaked and had several attempted repairs over the years (I will post about the the roof repair on a different thread) I have discovered the paint was doing a remarkable job of concealing just how damp the walls beneath are.
    The walls are plastered with a grey (cement based?) plaster (not plaster board) and having removed a small section of plaster near the ceiling the brick behind is very wet.

    I have scraped a lot of the paint away and would say a 1.5 x section almost to the floor and a 0.75m 3/4 of the way down is damp. I have put a dehumidifier in the room.

    I know this is hard to answer but how quickly is the wall likely to take to dry (assuming the underlying leak is fixed), weeks, months a year?

    Would removing the plaster to speed up the drying process significantly? Then once dry getting a professional in to re plaster.

    Thanks

    Good idea, when treating failed DPC's it is normal practice to re-plaster half way up the wall as the plaster may continue to be hygroscopic (got a taste for water sort of waterholic!) and continue to give trouble.

    And if the plaster is grey all through to the bricks it'll be a lightweight bonding with a grey siraphite finish, so yes get it off.
