Closing Crawlspace Vents this Winter

As colder weather approaches the Raleigh, NC area, certain preparations for homes must be made. Furnaces should be inspected, ceiling fans set to reverse, and windows and door frames caulked and sealed. But how does the crawlspace play into the winter checklist?

Crawlspaces are exposed to outdoor conditions, which can be problematic during harsh winters. Closing crawlspace vents in Raleigh is the best way to protect your home from the frigid cold, keeping it safe and comfortable all through the season. Contact us at Carolina Air Conditioning for more advice on readying your home for winter.

Why should I close my crawlspace vents?

There are multiple reasons to close the vents to your crawlspace during the winter, and they all have to do with the fact that vents are openings to the outdoors. When vents are left open, cold air is allowed to move into the crawlspace. This can freeze water lines, which cuts your home off from running water and can potentially cause serious damage. Once cold air is in the crawl space, it’s only a matter of time before it moves through openings and into your home, ruining your comfort and running up energy costs. A closed vent also keeps snow and rain out of crawlspace. Blocking of moisture is crucial to preventing mold and mildew from growing underneath your home. In addition, a closed crawlspace will prohibit animals and pests from sharing the warmth of your winter home.

How to close crawlspace vents in Raleigh, NC

If your vents have a lever that you push to close, you can prepare your crawlspace for winter on your own. However, other vents may require closer attention. Some require padding or foam sealant to be inserted. If a vent is without sealing mechanisms or mesh screening, it’s probably time to install new vents around the crawlspace. In addition, properly sealing and insulating crawlspaces will protect your home from seasonal weather and increase HVAC system efficiency. In any case, it’s a good idea to have your crawlspace inspected professionally before winter. Call your local Raleigh HVAC provider, Carolina Air Conditioning to inspect your crawlspace today!
