We have just removed our rotting 1970s wooden porch frame from front of 1918-built semi. Mostly good; however, now small gap in ceiling and lathes exposed. This was previously “inside” as inside porch. Obviously patched in recent decades with gypsum-based plaster as repair now evident...
Anyone tell me what the black cable is? I need to fill the hole below (mice ingress); there is a cable in the hole. I’d like to identify it (and insulate appropriately) before I fill gap with mortar.
Any help appreciated!
