What Nasty Things Enter From A Poorly Sealed Crawlspace?

Posted on: 21 May 2019

Crawlspaces are not spaces that you use for living. You may venture down there once in a while to store something, but you probably don't visit every day. As such, if your crawlspace begins to develop leaks or is not built as tightly as is should be, you may not notice right away. But be assured — there are plenty of nasty things that can enter through a poorly sealed crawlspace, including the following.


Water belongs on your sink and in your pool — not on your crawlspace floors. A little water may not seem like a big deal, but water can be a precursor to the other issues discussed in this article. It attracts bugs, and it is an essential ingredient for mold and algae growth.

Carpenter Ants

These large ants love moist places like crawlspaces. In fact, they like to build nests within damp wood, eating away at it as they burrow away. Carpenter ants can do a lot of damage to the floor beams, ceiling beams, and wall beams in your crawlspace. They may also attack and wooden items, such as picture frames, that you may be storing in the area.


A type of termites called dampwood termites love moist wood in leaky crawlspaces. You'll know if these bugs are around since you will notice their mud tubes — tubes of mud that snake along the outside of wooden beams. Termites can cause a ton of damage to wood in a short period of time, and applying insecticides and baits to the area will only go so far if you don't also take steps to seal off the crawlspace.


Where there is water, there will soon be mold. A few spores can blow in through tiny gaps in the crawlspace, and before you know it, you will have a whole host of mold growing on multiple surfaces. Mold can cause sneezing and itching, not only for humans but also for pets. Bleach can kill it in the short-term, but you'll need to dry the crawlspace out to keep it from coming back.

If you are noticing any of the above invaders in your crawlspace, it's time to look online for a crawlspace encapsulation service on sites like http://www.permadrywaterproofing.com/. They can line your crawlspace with a plastic barrier to keep moisture, mold spores, and insects from entering. Then, the methods you employ inside the crawlspace to get rid of these pesky invaders will be more effective.
