Basement exhaust fans are quite common in homes that have moisture problems.  Without a basement fan your basement literally holds in all of the moisture that is introduces via the walls and floor and drain pipes.  While having these fans does solve the moisture problems, you must make sure that the fan is properly turned on and off at the correct times.

Moisture is often a common problem when dealing with basements, especially in today’s newer homes that do no breath due to the advances in home insulation technology.  You should always make sure that your basement has enough air flow and circulation.  You can get basement air circulation by using a basement exhaust fan.

You must make sure that everyone in your family is aware that the fan needs to be turned on in certain circumstances.

It is highly recommended to install the fan so that when the basement light is activated, the fan is automatically activated.  Now this is for use if you have condensation problems when someone is perhaps washing something in the wash basins or running the laundry facilities.

You don’t always need to have basement exhaust fans, it really depends on the situation.  For a general condensation, you may easily get away with using non-active vents.  These vents are pretty much a hole drilled in the basement wall and venting to the outside.  There are usually a couple of these such vents that will be placed throughout the basement.  They usually do have louvers on them, so you can close them if you need in the winter months.

Maybe one of the simplest things you can do(again, remembering that different types of moisture problems can be treated with different remedies) is to have a fan active that is just your standard fan.  This fan can be any fan that you may have around your house.  This will not move moisture to the outside of the home, but it will stop moisture from collecting and creating moist or wet spots in your basement.

If you have any signs of moisture in your basement, it would be advisable to figure out where the moisture is coming from and use some of the fan techniques mentioned in this article.  I’d venture to say that most of us do need a basement exhaust fan to control moisture.

Emergency Basement Exhaust Fansemergency basement blower fan

Emergency basement exhaust fans really come in handy when you have a sewer back up, a sump pump that fails or some other form of emergency which involves large amounts of water or moisture in your basement.  The blower to the right is the Stanley High-Velocity Blower Fan.

I’ve had to use mine at least 4 times this year alone, not to mention how many times my neighbors have asked me to use it.  This particular model is a high velocity blower.  I’m not sure if you can tell by the picture, but the head actually swivels on that, so you can get pretty much any angle you want out of it.

After what I have been through this year with our basement, I definitely would recommend some sort of basement ventilation and/or an emergency basement exhaust fan for emergencies.
