Hi All, first post here, so apologies if this is in the wrong place! We moved into a new house last year - early 1980's, suspended chipboard floors throughout. Every internal doorway, upstairs and down, has an ugly strip of dark stained wood along the bottom; these are full width of the doorway and approx. 5" wide. First question: what are they called? I suspect either door- 'sill' or 'threshold', but have been unable to find any images online that are an exact match. Second question: we are soon going to put down engineered wood flooring in a couple of the rooms and want to remove the sills/thresholds/thingimy-bobs. If anyone has encountered these before, what am I likely to find beneath? will there be a gap between the chipboard flooring either side or will the chip' meet and the sill/threshold simply be fixed on top? I appreciate that I probably won't know for certain till I lift one and have a look, but if anybody has experience of these and can point me the right direction, that would be great.
