Hi all so my partner has a house that has rising damp so we took off rhe interior living room walls until bare brick. However the previous owners bricked up very poorly a fire place. We’ve now opened it up, they threw everything down the chimney when they took off the roof part and capped it. We’ve now got rid of all rubble and debris.

Got it back to the original tiled opening. However it’s damp. Even though it’s been closed for many years.

Could the screed be something causing damp here? Or would the damp in the opening dry up now. The interior of the chimney is dry.

The previous owners were DIYers and bad at that.
