I have just finished painting one of our bathrooms which has a skylight. Tonight I thought I saw what looked like water stains at the base of the skylight running down the wall. Upon closer inspection that is what I found along with small bits of ice where the condensation had ran down the pitch of the window and dripped down off of the skylight on to the walls. How can I stop this from happening? The moisture was on the majority of the molding around the skylight. I live along lake Michigan in Wisconsin, it is of course winter and our current temp is in the single digits I keep the house between 68 and 70 degrees. The skylight faces west and the heat register in the bathroom is also on the west wall under the skylight. The bathroom has not been used for a while so there have been no hot showers or baths to steam it up. The house is a ranch, I don't know much about the skylight other than it was installed when the house was built and hopefully right. Thanks in advance!
