    I think the old chimney breast needs a lookin into. The redundant shaft (if I'm reading correctly) should be vented, otherwise condensation can occur, the water from which has to go somewhere. Best check this out as possibility, some sort of humidity sniffer lowered into shaft would give a good indication...bosshogg :)

    I need help. We recently started renting a house and noticed that after moving in, room started getting dark spots on the ceiling. When I brought it up to my land lord, they said that it had to be mold or mildew from the humidifier that I run everyone once in a while (and always with his door open). The stuff just appeared one day, doesn't mold take a while to accumulate? So any way, I gave my husband a bucket of bleach water and a washcloth yesterday and sent him in to take care of it.
