Installing a crawl space vapor barrier is essential for preventing moisture from seeping up through the ground and into your home. It's basically a heavy-duty plastic sheet laid over the soil inside your crawl space, which stops dampness from rotting wood or feeding mold. You'll want to overlap seams and tape them tight against walls to seal everything properly. It's a simple job that makes a huge difference in air quality and keeping your underfloor dry.
