Today we will talk about certain practices that keep moisture out of your crawlspace.


To Vent or not to Vent That is the Question

For many years it has been considered best practice for a home to have vents in its basement or crawlspace. It was thought to prevent moisture build up. However, more recent research has found that it is actually better to leave the crawl space or basement unvented to prevent moisture build up! The more you know about new research the better when it comes to your home.


Ground Humidity Issues

The EPA says that 80% of moisture in the home comes from underneath it. If you have high moisture ground under your home then you should definitely have some really great vapor barrier put under your home. Even if you don’t live in a terribly wet area using vapor barrier is a great way to protect you home.


If you have very bad ground humidity issues, such as living somewhere with a high water table, then you might need to go with more extreme measures. If you have a constantly wet basement or crawlspace you may need to consider putting in a sump pump. This will drain the water towards it and pump the water away from your home. It is a great option for those with a lot of moisture under the home.



If you have a home that has mostly soil underneath it rather than slab, you may want to consider having your crawlspace water-proofed or encapsulated. This is a great way to keep moisture out of your home. This may be a great option for your home if moisture is a real problem. The great thing about waterproofing or encapsulating your crawlspace is that this area will become a usable storage space because your items will be safe. It also helps your home conserve energy by blocking the passage of air.
