How To Vent The Crawl Space Properly
Crawl Space Ventilation
This subject gets confusing only because it seems to be the entry point to sell you something. Honestly, if you are researching this subject you probably do need to buy something, but that is beside the point here. The question is; Should you vent a crawl space or is it better not to? The best answer is another question; What do we do with basements? What I am getting at is this, yes you need to vent your crawl space, but that does not mean you have to vent it to the outdoors. Look at how a home that is built on a basement is designed, no outside vents. Crawl spaces are no different if you employ all the other attributes of a basement as well.
The biggest key to getting the crawl space under control is making the environment controllable. This means closing up the outside vents and treating the space like it is part of the home. Of course you cant do that until you have a way to manage the moisture that escapes from the earth. That solution is called Crawl Space Encapsulation. Is this starting to sound complicated, well its not really. The link above will explain a lot about it and even though it can be technical to do properly it will put all your crawl space woes to bed for good.
So once that is done we still have to tackle the subject of proper Crawl Space Ventilation. Just like most basements need a dehumidifier, most crawl spaces need a dehumidifier. Even if you have a closed or conditioned crawl space like a basement. This is due to many reasons, mostly summer dew point in the area you live in.
