MRM,respectfully I think if he pulls the trim from around the windows on the inside
the only thing he will see is drywall. Maybe in Florida they drywall differently but
I know in The Pacific Northwest drywall butts right up to the casing and the trim
is attached to the top of the drywall.The only way he is going to see any rough
framing is by pulling sheetrock which I don't believe is very practical. I do agree
with you that trying to find area's of air infiltration is a good place to start. Also if
this years winter is much colder than last year that could be a factor.
