Crawl Space Vent Covers

Should you cover your Crawl Space Vents?

Much like the flood vents that they are meant to be affixed to, crawl space vent covers are a hotly debated topic in the energy efficiency and contracting business. There are two main viewpoints, each contradictory to the other, leaving many homeowners confused about what they should do for the health of their crawl space.

Opinions vary about Crawl Space Vents and Covers

There is the side of the argument that says crawl spaces shouldn’t be vented, and if they are, they should be as closed off and as sealed as possible. Studies have shown that vent covers help keep vented crawl spaces mold and rot free by preventing damp air to enter.

More than just protecting the home from mold, these vent covers protect the insulation from the damaging effects of the outside and help keep the humidity in the home above at an acceptable level, along with protecting the home from pest infestations.

On top of all of this, supporters of vent covers champion their ability to help lower energy bills. Unsealed vents allow unconditioned air to enter, forcing your system to work overtime to heat or cool the air for you, resulting in higher energy bills.

But still, those against them say that they block the airflow that allows the crawl space to dry itself, claiming that naturally occurring groundwater will have nowhere to go and will remain in liquid form. This groundwater in your home is a breeding ground for mold and pests, especially in the summer. In the winter, when the air is drier and the groundwater is frozen, vents can be closed to prevent extra cold air within the crawl space, limiting how much work the heating system will have to do.

Finding all the answers on your own can be frustrating, which is why it’s sometimes best to reach out to a professional for a second opinion. Get started today by searching for your local expert here at HomePro Match!
