Is A Vapor Barrier Necessary In A Crawl Space?

Yes. In order to keep moisture out of your crawl space, you should install a vapor barrier. Furthermore, a moisture barrier is the bare minimum of protection that you should have installed in your crawl space to keep it dry. A vapor barrier might save you money on costly repairs.

Do Vapor Barriers Cause Mold?

No, vapor barriers do not cause mold to grow in crawl spaces, it is the opposite as they help prevent the growth of mold under your home. This is done but blocking a large amount of water vapor from evaporating from the soil and rising up into the crawl space and then being absorbed into the wood framing leading to mold growth and wood rot.

Is It Common To Have Condensation On My Vapor Barrier?

The accumulation of water and dampness in a crawl space is a very common problem. It is possible for puddles to form on top of a liner if the vapor barrier has been improperly constructed (see photo). It's natural to assume that having a moist crawl space is typical because it is a below-grade space under the house but the area should always be kept clean and dry to prevent structural damage and poor indoor air quality.

How Do You Install A Plastic Vapor Barrier In A Crawl Space?

• Create proper drainage around your home to prevent rainfall from entering. The easiest technique to reduce crawlspace moisture is to slope the soil away from your home by 1/2 inch every foot.
• Cover the dirt crawlspace with a polyethylene moisture barrier. Tape any overlapped seams. And fix the plastic about 6 in. up the wall. Keep the sheeting in place with landscape fabric pins.
• Insulate bare foundation walls with 1-1/2 in. of strong moisture-proof insulation. This in itself insulates the walls and moreover prevents rising damp from entering the crawlspace. 
• Insulate rim joists to stop air leaks.
• The interior of the foundation wall should be covered with a 6-mil plastic at a minimum to keep out moisture and pests. However, building codes in your area may need various specifics for termite management.

Can I Put A New Vapor Barrier Over Old?

Adding a new barrier to your crawl space is one method of making it more inviting. Plastic that is old and torn has lost its effectiveness; disregard it at your peril. The areas that have been torn do nothing to aid in the creation of a moisture barrier. This means that you have no control over moisture.
