​Bathrooms, as we know, are warm, humid environments.  Because of this, it is important that they have a good system of ventilation which is designed to extract moisture and even odors out of the home.   This usually takes the form of a fan in the ceiling connected to a duct that comes out of the homes exterior.  There are a few reasons why this type of fan will not work effectively. 
 
One reason is that the duct connecting to the fan does not actually reach to the outside of the house, instead it might only be ventilated into the attic space.  While you may feel that this doesn’t affect the bathroom it can cause problems in the attic, creating an environment which will cause decaying of materials and mold.
 
Another reason a bathroom exhaust fan will stop working properly is if it becomes clogged with dirt and dust.  This is a problem easily fixed with safe and proper cleaning.
 
If you notice things like excessive moisture on the walls of your bathroom, metal fixtures starting to corrode, peeling or bubbling paint on the walls or high levels of humidity, these might be a sign that the ventilation system is not working.  Please feel free to contact us for your home inspection needs.
