Wood Basement Walls Wet at One Time
 
The basement is 1/2 block and 1/2 wood walls, the wood walls being on the walkout side, none of the wood is below grade. The walls had insulation put in and it was just sitting there, no vapour barrier. The mice got in and made a mess and insulation eventually fell out in many places. There are no signs of water entering from the outside but the walls have been wet and are greyed, mold? The house was heated for 2 winters with just this pink insulation and no vapour barrier ... could this be from condensation build up? Brand new house basically abandoned, last 8 years. I want to fix it up to sell but am concerned about the source of
the moisture but as I said .. it doesn't seem to have come from outside at
all. thanks:huh:

Welcome to the Forum!

if you could edit your profile to include your location it would certainly help in getting useful responses as location determines how buildings are to be constructed.

This house is located just east of Minneapolis, MN on the Wisconsin side. Another site mentioned moisture in the walls due to the high humidity of the area but there was no vapour barrier on the inside of these walls to trap the moisture so I am leaning towards condensation on the walls due to temperature variance but I don't know. The place was housewrapped so could that have trapped moisture within? I noticed the corner beads in some rooms is getting rusty too..:whistling2:

Pictures? They would help a lot.

Thanx

tape up a 2.0 x 2.0 pc of plastic sheeting for a few days & check where the moisture collects,,, between the plastic & the wall, its being transmitted thru the walls,,, on the face of the plastic, its condensation from room air

Okay pictures were posted under photos? Good idea about putting up some test plastic, thanks. Thanks for your patience. :eek:

"The walls had insulation put in and it was just sitting there, no vapour barrier."
"The house was heated for 2 winters with just this pink insulation and no vapour barrier ... could this be from condensation build up?"
" I noticed the corner beads in some rooms is getting rusty too." No drywall in basement on the walls, just insulation w.o. vapor barrier. Yet corner bead is rusting under the drywall texture.... I'm confused. The moisture is from the gas furnace or the moving air is lifting moisture from wet areas to spread it on the colder walls where it condenses to water from vapor. Due to temp diff., as you said correctly; http://www.buildingscience.com/docum...bout-diffusion

The corner beads upstairs, sorry for the confusion. Thanks for the feedback.
