Fitting a new kitchen so pulled up the Laminate flooring that has been down since we moved in in 2005. Under the laminate was a mouldy underlay, and under that plastic sheeting on top of the original wooden floor boards. (house from C1900). Needless to say they were damp in places, but worse there is a lot of active woodworm in at least the boards (and probably some beam). Floor is a suspended timber floor, and walls are 1m thick stone, rooms about 3.5mx3.5m I can get the structure treated, but need to remove any damaged boards, im looking at probably 60% removal. I see I have 3 options 1, replace the remove boards with modern whitewood floor boards. 2, pull up all the floorboards and replace with MR chipboard panels 3, go for a mix of chipboard and original flooring. The plan is to lay Modern Vinyl tiles on the floor when its back down. Any thoughts or is it literally a coin toss decision?
