The good news is that if you’re willing to condition your crawl space, you can reap the benefits. These are a few of those benefits.
Reduced Allergy Flareups
A small but significant benefit of a conditioned crawl space is that you’re less likely to have allergy flareups. Dust mites, mold, mildew, and other moisture-related issues can trigger allergies, which means it’s common for allergy sufferers to have a hard time in moist homes. You might not even realize that this is what’s causing your allergy flareups.
When you take steps to avoid moisture in a home’s crawl space, you can also reduce allergies for yourself and people in your family. This benefit alone can be worth it for many allergy sufferers, as mold and dust mite allergies can feel unbearable. Some allergy sufferers don’t even realize they’ve been having allergies until those allergies are gone.
Even if you don’t have serious allergies, it’s not fun for anyone to have coughing or sneezing fits, no matter how infrequently they occur. Wouldn’t you rather reduce the amount of coughing and sneezing you have to deal with, even if the amount you’re dealing with is already relatively low?
Perhaps the largest benefit of conditioning your crawl space is the energy savings. Advanced Energy has performed research to suggest homeowners may expect 15%-20% energy savings with an encapsulated crawl space versus an unencapsulated crawl space. It might not seem like much at first, but this is actually a huge amount.
When you do the math, you’ll realize that this can add up to huge savings over the time you live in your home. For many families, an unsealed and vented crawl space is wasting the monetary equivalent of up to 20 full tanks of gas every year. That’s enough savings to potentially offset the cost of encapsulating your crawl space.
Crawl spaces contribute to excess heating and cooling bills year-round because the outside temperature more easily comes into your home. That’s not the only way it impacts your bills, however. It also increases the relative moisture in your crawl space. High-moisture air is much more difficult to condition, which means you’ll probably turn the thermostat up and end up with a higher energy bill.
