Should you vent your crawl space?


IMG_0729

If your home has a crawl space with plastic laying loosely on the floor and insulation above your head inside the floor joists – you are wasting energy, have poor indoor-air-quality, and could be growing mold.

In our mixed-humid climate, we should seal and condition our crawl spaces. There should not be insulation inside of the floor joist, but should be on the walls and on the floor if possible. There should be a small supply from your heating and cooling system to create positive pressure. These strategies reduce your annual energy use, protect your indoor-air-quality pushing moisture and radon out, and protects against critters getting into your home.
