Expert: David Deal Date: 1/19/2008 Subject: condensation on windows
Question I have what in Illinois is called an English Basement. In the lower level condensation forms on the lower area of the windows. Lowering the humidifier makes it to dry upstairs however my real question is this. Is there something I can put on the window area to stop the formation of water as it then runs down to an inaccessible area where mold is forming. Changing the setting on the humidifier works somewhat until the weather changes. Thank You. Andrew Giddeon.
Answer OK, first the condensation forms due to temperature differential between inside and outside with high humidity on the inside. First thought along those lines would be to lower hmidity OR increase air movement such as blowing air against the windows. Even running a ceiling fan can accomplish this goal.
You can also consider replacing the windows with double pane ones that will prevent condensation.
If it were my basement, I would install dehumidifier with digital reading and auto drainage. Use condensate pump if yuou cant install normal natural drainline. St it to 50%. Then I would increase air movement using a ceiling fan. If the condensation still exists, then seek air leaks or other sources for high humidity air. The ambant air in room is 50% so no condensation should occur.
Now, what is an English Basement, honestly have never heard that term but I am curious.
