Somewhere lurking at the back of my mind (and possibly nowhere else) is a clause in strata law that says lot owners have a duty to care for any common property that forms part of their lot.
Regardless of that, the simplest answer is for you to tell the owner who want their parquetry repaired that if she’s not happy with your offer she can take you to Fair Trading – which you’ll be happy to do.
As for the person who wants the new floor, tell her you will pay the same amount towrads the new floor as you would have for the repairs, once it is laid to your satisfaction (re insulation etc) provided they take ongoing responsibility for its maintenance from here on in .
