Due to Termite and (believe it or not) Raccoon damage, my house sill
plate might need changing. The sill plate has certain sections that
have been eaten away at… none of these locations is under a rafter
location.

So, the question is, if my sill plate does NOT have rot and is NOT
disintegrating due to termites, is it possible to patch the sill
plate? Or should I undertake the expensive task of replacing it?

Thanks,
Raj
