    Hi,
    Recently moved into a 1950s detached house which is a renovation project.
    All of the windows were replaced by the previous occupant with UPVC ones. The issue is that the upstairs upvc window appeared to be not sealed and all the plaster below the window had blown. I have removed the plaster and as the house is Brick built with a cavity removed the 3 layers of inner bricks below the window as these were soaking wet. I have now found that the concrete ledge under the window has a gap between the bricks and the ledge with what appears to be a corroded and rotted bitumen type DPC which has been allowing water ingress and soaking the bricks. As the gap is only a few mm and the house has now got upvc windows could I simply remove the DPC then fill both sides of the gap with high quality sealer or would it still require a DPC before relaying bricks and plastering
    Thanks in advance
    Dave

    Does an upstairs window, or anything else upstairs, require a DPC? I was under the impression that damp is not going to rise above about a yard or so.

    DPC is required wherever a cavity is closed at cills and jambs.
