I'm about to clad the fascia boards on my house with UPVC fascia cladding
(10mm thick). The existing wooden fascia boards have a little wet rot in a
couple of places. So I'm thinking of treating those sections with some kind
of wood presevative prior to nailing the cladding in place. I just want to
make sure I don't use a preservative that's going to exude chemicals that
could affect the UPVC in any way. Any suggestions?

I would replace the affected woodwork, but there is no way I can do this as
I can't afford a scaffolding and am doing the job with a ladder only.

I'm wopndering if it's even necessary to treat the affected fascias,
because wet rot stops as soon as the wood is no longer subject to dampness,
I gather. Any views?

I suggest you post your question in uk.d-i-y. AFAIK, if you apply
preservative or paint, once it's dry it won't affect the PVCU.
However, neither will it cure wet rot. If you seal moisture inside the
wood then you may make any problem worse. So better to check with the
"experts" in the other group.
