When a home has a crawl space with vents, often we will find that those vents are blocked by earth, leaves or organic matter. They are at grade and, in many instances, the homeowner needs to put in wells at the vents. These can be pre-purchased in plastic or metal. Sometimes people make them of pressure-treated lumber. The wells are of little use when, over the years, the homeonwer than allows the wells to become full of debris which turns to soil and, once again, the vent is blocked and below grade. This information applies equally to wells at basement windows. Thanks for stopping by, Steven L. Smith
