When trying to improve the humidity of your crawlspace, there are many actions you might consider taking. However, some of the solutions used to improve a crawlspace are not recommended and might make the situation worse.
Relying on a Dehumidifier
You might want to dehumidify your crawlspace. But regardless of how powerful your dehumidifier is, it will never be able to dehumidify a crawlspace because your crawlspace is exposed to the outdoors. Getting a larger dehumidifier will simply increase your energy bills while having little impact on your humidity.
Not Solving Water and Mold Problems Before Encapsulating
Do not forget to eliminate mold and water issues before you encapsulate your crawl space. These problems will not automatically go away after your crawl space has been encapsulated and might be more challenging to solve afterward.
You may not realize that your home is not as great as it can be. You may find yourself often sneezing and not even realize that your sneezing is a result of your crawl space not being encapsulated. You may also notice that your home smells very differently after a crawl space encapsulation. Humidity contributes to mold growth, which can cause both of these problems. However, if you do not treat the mold problem before encapsulating your basement, you will not experience the full benefits of encapsulation.
Relying Only on a Vapor Barrier
Do not think that simply adding a vapor barrier will be enough to protect your basement. The vapor barrier will stop moisture from entering your crawl space from the ground, but it is not enough to stop moisture entering your crawl space overall.
Not Encapsulating Your Crawl Space
The costs of crawl space encapsulation are not as high as the costs of having wood-destroying insects infest your home and cause damage. Termites can cause such extensive damage that you may need to have your home condemned. However, crawl space encapsulation creates an environment that is not hospitable to insects.
You'll also save money on energy costs by encapsulating your crawl space. Without a crawl space encapsulation, heat can easily enter your crawl space and your air conditioner will have to work harder to make sure that your home stays cool. Depending on the size of your air conditioner, you may never have a home that feels cool enough even when you have the AC running constantly.
Because of all of these benefits, it's a good idea to encapsulate your crawl space. But also remember to take care of your mold problems beforehand.
