Our bathroom borders the hallway, a bedroom, the dining room, and an outside laundry room. The long side of the shower is against the dining room. The water controls are on the laundry room side and the hallway is against the other end of the shower.
We recently had a HVAC unit installed innour 1973 brick home. It never had one. We have now noticed our dining room and hallway paneling buckling. We tore it out to find condensation and mildew/mold growing? The plywood under the tub was wet as was the 2x4 studs. No insulation in interior walls but on the laundry room side there is pink/paper backed insulation. R19 I believe? 2×4 walls. Attic doesn't leak and nothing wet wet up there.
For a month orbso, we had some paneling and insulation out of the laundry wall to install a new tub drain. We are thinking the hot outside air came through this hole and under/around the shower causing it to condensate? 100 degree summer days. I put new insulation around plumbin and reinstalled laundry paneling. We put up clear plastic sheeting 1.5 mil where indoor paneling had been removed. Still much condensation on plastic.
We took plast c down and ran fans on wet wood under tub to dry everything out thinking that might be the cause. Haven't reinstalled plastic or paneling in hall or dining yet. I sprayed foam insulation around tub drain pipe to crawlspace. I put new insulation under floors near bathroom. No leaks under house.
New AC keeps house about 72 and there's a vent blowing near dining room wall. Another vent in bathroom. House is cold. Bathroom vent fan is.working.
Attic is insulated all over with blown in type. No gaps. Outdoor laundry room ceiling is seen in attic and it has dropdown ceiling with blown type on ceiling and pink Batts on side walls.
1. Any suggestions on cause or fix?
2. Should I insulate around shower before installing new hall and dining paneling? If so, what type and if paper backing which way should paper face?
My assumption was.
Plumbing work let air in wall and caused condensation. Then wood got wet so when wall put back, water trapped inside wall. Plastic sheeting sweating because water trapped in wall and cold AC blowing on plastic. Now that all is dry, should be ok to put paneling back with maybe insulation batts?
Any ideas anybody? I can compress pics and send if needed.
