Hi there. Maybe someone can help me. I have recently bought a house. I am doing it up gradually and at the moment I am wondering how to deal with gaps under the door frames. There had been dry rot and the frames were cut because the bottoms of them were rotting- not sure if that was cos of dry rot of just moisture of touching floor. I have gaps under the frames. On some gaps the gap is between the frame and the subfloor and on other doors it is between the frame and the actual flooring- tiling. I am wondering what is best to use to fill the gaps. Will decorator's caulk do?
