We are having a problem with our bath window leaking. We had replacement windows put in a few years ago. Ever since then, our bath window leaks. The insulation around the window is soaked. The sill and quarter round going around the window showed water spots. That's how we found out it was leaking. On the outside portion of the house, there are ice sickles hanging from the bottom portion of the bath window. There are also ice sickles coming down the siding of the house from where the exhaust vent is and the attic vent. We thought it might be the warm moist air coming from the bath meeting the cold air outside and causing the window to leak, or the insulation to get soaked. We don't know though. Can anybody please help us. Wallside Windows pulled the window again, only to tell us that it's not the window itself leaking. Please help me. We live in Michigan where it's really cold right now.
