Moved into a house which has had woodworm in the suspended ground timber floor, mostly in the kitchen but some of hallway too. Half of the kitchen subfloor is broken-up chipboard anyway, so just replacing the lot.
Originally there would have been 170x22mm finished size T&G timbers running all the way through the kitchen, under the stud wall into the entrance hallway, so plan A is to dovetail existing non-rotten boards in the hallway. However, seems getting equivalent replacements isn't going to happen.
Plan B is to use something like WBP ply or HardieFloor (looks fancy---has anyone tried it?) in the kitchen, stop at the joist that supports the stud wall between kitchen and hallway (admittedly there wasn't a joist under it before, but there will be!). Then deal with the hallway separately, at least will have a kitchen again.
Plan C is to replace all the way through with different size T&G, somehow propping up the staircase and multiple door frames whilst doing it. Doesn't sound like a lot of fun.
What's going to be the result of doing something like B, i.e. having a joist down which the floor isn't interlocked? Okay with beaucoup noggins to the surrounding joists or a definite no-no?
If I did need to do it, how does one replace a floor that has a staircase on top, ideally without getting a staircase on my head?
