April showers bring May flowers, but they also have the potential to bring mold & mildew to your crawl space if there isn’t adequate ventilation and a vapor barrier. It’s a good idea to take a look at your crawl space as we head into damper weather, and make sure there is adequate ventilation in your foundation walls, and those vents are open. A good vapor barrier with overlapping sealed seams will also protect your home from moisture coming up from the soil beneath your house.
