The bathroom exhaust fan has a very important role. To remove excess moisture away from the bathroom. This is important to prevent water damage and prevent the growth of mold and mildew. Improper installation of the bathroom exhaust fan can lead to all kinds of problems, and in fact, is a common building code violation. Many homeowners might not even know that there is a problem with their bathroom exhaust fan. Here are some things to look out for and what you can do.

Signs There is an Issue

There are several things you should be on the lookout for if you suspect that your bathroom exhaust fan isn’t working properly.

In addition, if you notice any mold or smell mildew there could be excess moisture building up from improper ventilation.

Consider installing a timer that allows the exhaust fan to run for a specified time frame. To learn more contact Courtesy Plumbing today!
