Why do my windowsills keep getting wet, then end up with black mold on them?

Joe M asked:


We live in Wisconsin, where it is very cold from November-March. I realize that condensation is causing the wood on the windowsill to get wet; is this due to the quality of our windows? Is there anything that I can do to stop this (possibly caulking between wood and windows)? Any way to clean the black mold off of the wood? Will sanding the wood and re-staining clean this up?
