3 Reasons Crawlspace Moisture Occurs
Your crawlspace isn’t the most inviting place to visit. Trust us, we’ve seen our fair share of crawlspaces that wouldn’t make it on a brochure. But, unfortunately for many home owners, the side effect of an improperly sealed crawlspace is something no one needs: Crawlspace moisture.
So with so many homes built upon a crawlspace, it’s not uncommon to see crawlspace problems related to moisture. These include:
- Musty odors
- Condensation, or sweating on ductwork
- Condensation on pipes
- Hardwood floors buckling
- Humidity problems in living areas
Depending on where you live, these problems usually show up when the weather gets warm, which amps up the problem.
But why does this happen? It comes down to three main reasons.
- Excess Water: Look for standing water in your crawlspace. If you find it, you have one of two problems: drainage issues, or leaky plumbing. Both of which you never want in a crawlspace. This usually happens when ground water isn’t diverted properly, the ground slope is off, or there is not enough exterior water-proofing to prevent water from entering your dwelling.
- Evaporated Moisture: This one is bit more tricky, but is no less common. What happens is the ground, which is typically covered by a protective plastic to prevent moisture, has too much water under it, and the heat from the warmer months causes it to evaporate. The same thing can happen with your walls too. A well installed vapor barrier usually fixes the problem.
- Unsecured Vents: When outdoor air is introduced into your crawlspace the relative humidity increases. So if an outdoor vent is letting this air into your crawlspace you will get extra moisture that you don’t need. Take a walk around your home and check for air leaks. Not confident on how to do this? Time to call a professional.
