Why is the interior of our exterior sheeting wet?
Renovation on master bath, took drywall off, then vapor barrier and insulation, house is a very well built ( we built it) 30 yr old home, two story, and noticed inside of exterior sheeting wet? Also whether related or not, have had dark dirty water migrating down outside of vinyl siding, in area of this bathroom. Just had siding replaced 5 yrs ago from aluminum siding. Had typar placed as well, have had many contractors look, seems many suggestions, but no solid reasons why?
Have checked attic, ventilation there, moor venting, etc all good. After one contractors advise, I installed a 12 X 12 stack vent and sealed off large ( 24 x30) gable end vents I had as he said the new theory was to discourage cross venting and encourage soffet venting up Thru to peak. We are confused, frustrated and cannot seem to get anyone to solution?
Can you help?
Trust me, ask 10 people ( contractors) and get 10 different answers :0(
There is more I could say, but will wait to answer verses bore you right now.
