If it's exterior, then it's no good. Pine is not a good choice for exterior. A year, maybe two I'm guessing and it's got blue rot. Once water gets in there, it's over.
There really isn't a species of wood that should not be used outside.Craig,
Please tell me what species of wood you use for your Millwork, and where it comes from. I'll be glad to fill you in on why it shouldn't be used outside from there.
