Do you leave your crawlspace vents open or closed? The great debate ends now.
If you guessed open, you are right. If you guessed closed, you are also right!
Crawlspace vents should be opened in the spring and closed in the fall. The reason being that you want to preserve any heat in your crawlspace in the winter. This will help protect your water pipes from freezing and keep your home a little cozier on those cold days. Once spring arrives, go ahead and open the vents to allow better air flow in the crawlspace and to eliminate moisture build up.
Adjusting the vents should take you 5-10 minutes total.
Usually, they will slide freely open and closed with your own hand strength.
Occasionally you’ll run into a stubborn vent that might be rusty or stuck. Use pliers or a wrench to grab the vent tab as close to the base as possible and gently tap on the wrench with a hammer.
The only time you shouldn’t close your vents is if you have high radon; an appliance that can build up fumes; or excessive water and moisture problems. If you have these issues, you have bigger problems than worrying about your vents being opened or closed. Consult with an expert to remedy those situations immediately.
