We have T1-11 siding that is looking the worse for wear: some rotted

the studs?


How old is the house?

What would be involved in replacing it by Hardie-Plank? *Not* installing
the H-P over the T1-11. Insulation between the joists, plywood over the
joists, then Tyvek housewrap, then the Hardie-Plank?


I've seen 20# roofing felt used as a moist wrap - before Tyvek house
wrap came about.

Would it be possible to replace one panel at a time, or would I (or a
contractor) have to do a whole wall in one go?

Am I missing anything?

How long to do the entire house?
