Bathroom fans

Bathroom stays wet despite exhaust fan

Q.  Every time we take a shower, the walls just get very wet and sometimes the water runs down the walls. We have a very good ceiling fan. We are at our wits end, what could be causing this problem? Any advice would be greatly appreciated.

A.    Have you checked that the fan exhausts outside through a gable wall? And that the outlet is not blocked? If the fan exhausts in the attic itself, or through a soffit, gable or ridge vent, it is not doing its job and you should have that taken care of. Your family may also be taking some long or very hot showers; that will overwhelm the ability of the fan to keep up with the moisture generated by the showers.
