So I was running Ethernet around the house, and there were a couple of places where the top plate holes were incorrect and I had to redrill (holes no bigger than a 3/4 an inch). I got everything drilled right and ran....however what should I plug the other couple of holes with? (Just to get them filled). I doubt it did much structural damage (since it's just a single hole), but I still feel like I should "fill" them with something?
Is there some sort of wood filler? Or something? I know I should use fire-retardant foam where the ethernet cables come through...but right now just concerned with the holes that are just open.
