My house is a north london victorian semi. The floorboards under the
carpet are in a sorry state but what's more, where the back of the
living room used to be a kitchen, there is a small area that has
tiling rather than floorboards (I don't know what is under the tiles).
I want a new wooden floor (now that we have a dog, carpets are not
such a good idea) and I'm tempted to just lift the skirting boards,
lay a new floor over the old one, then put the skirting back. Is this
ok with regards to ventilation etc - any issues with doing this? Or
is the only way to replace / fix the existing floor?
If I can overlay a new floor, is it ok to nail the boards to the floor
