We're having our house built in Ottawa Canada, the days before and after they close up the walls with drywall, it started raining heavily for days. We went to see the house this weekend and the floor has traces of water stain near the walls (but it's dry right now). We are suspecting the insulating material are wet since the vinlyl on the exterior of the house have not been put on. Would that be a problem later on? We have brought up the issue with the builder but they told us we should not worry since there is a plastic between the insulation and the wall so mold will not develop. But what about the wet insulation? We do not know much about construction so any knowledge you can provide will be greatly appreciated. thanks.
