The majority of homes in central Virginia are built over crawlspaces. Most of us don’t want to think about our crawlspaces, and why would we? A crawlspace that has not been retrofitted has a dirt floor, is likely damp, may show signs of rotting wood, mold, mildew, critter infestation, radon--all kinds of unpleasant things. Like most unpleasant things, we want to block our crawlspace from our mind. But, there are some very important reasons why you shouldn't.
The Top 3 Reasons You Should Care About Your Crawlspace
Crawlspace air is bad. It’s cold in winter, it’s humid in summer, and if it’s damp, it’s likely filled with mold spores, fungus, and rot, which means it smells. This air seeps into your living space one of two ways, through the "stack effect" (warm air rising through all the small holes and cracks in your floor and pulling new air in behind it) and through your duct work if it is located in your crawl. This means you and your family are breathing bad air--unhealthy air that can lead to respiratory illnesses.
Radon. In December, we posted a blog about the dangers of radon, the second leading cause of cancer. As with unhealthy air, radon is a radioactive gas that can get sucked into your home through your crawlspace.
Higher energy bills: damp air takes more energy to cool in the summer and heat in the winter. And, again, if your duct work is located in your crawlspace and shows any signs of loose joints or crimpled seams, then you’re likely losing a lot of the air you’re paying to heat or cool to your crawlspace. To add insult to injury, your return ducts are also sucking in the bad crawlspace air.
The Truth about Vented Crawlspaces
According to Larry Janesky of Basement Systems, Inc., “Venting just doesn’t make sense unless the outdoor air is 70 degrees and 45% relative humidity day and night, year round.” In other words, vented crawlspaces in our area don’t make sense, and yet most of them are. While the vents are meant to allow air to flow through the crawlspace from front to back or vice versa, in reality the air flows up—into your living space.
There Are Solutions, and Weatherseal Has Them
Fixing your crawlspace is a home repair you can’t afford not to make. Controlling the air infiltration in your home is crucial to your family’s health, comfort, and your home’s energy usage. Encapsulating your crawlspace and bringing your duct work into conditioned space, remediating any mold, and mitigating radon if you have high levels are all services that Weatherseal provides. We also have moisture prevention services such as sump pumps, dehumidifiers, and gutters.
