One wall of my house is rendered and due to change of ground level I now need to patch up the render as there is exposed brick.
The plot is sloping so the damp proof course is about 60cm above the ground and currently there is no drip bead, the render is bridging the DPC but no damp issues inside. Currently there is a crack in the render where the DPF is.
I'm not sure whether to fill the (hairline) crack with flexible filler and just patch the lower area (i.e bodge it) or cut out a long section to install some drip bead. My worries about cutting out render to install drip bead is that I might end up with hairline cracks above and below the beading where I've repaired the render...also I'm not sure if there is much point installing the bead if I'm going to render the bricks under it anyway? The house had been clad in some horrible fake stone previously so I doubt the brick finish can be restored, so the lower section will need to remain rendered...
Any advice welcome.

Bridging a DPC isn't recommended, but YMMV if it works...
