Should I Seal Off My Foundation Vents?

Find out whether you should seal off your foundation vents. If your house is designed to have a vented foundation, you should definitely have the vents. If your house has a moisture problem, sealing off the vents is not the solution. Instead, look at drainage conditions around the perimeter of your foundation. Make sure your gutters are clean and free-flowing and that the downspouts are extended far away from the foundation. Also look at the grading; make sure the soil is sloping away from the house.
