Please could someone offer some advice as to how I can fix this? Our cowboy builders haven’t covered all of the upstand with edpm so I now need to patch it.
What’s the easiest and best way to do this?
Thanks

Hi zoeanddan
Fit an extra piece of epdm to cover the flake board and take it up under what looks like a trim finisher, if the finisher can be removed fit the epdm strip under it.
