    Vapor barrier

    My parents have this vapor barrier on their crawl also. It is still damp. Their water pipes sweat a lot and i am guessing i need to stop that by putting insulator wrap on it. I made sure their TWO vents were open as one had plastic closing it. Not sure if that is right. I also made a screen door 2x3' instead of the plywood to help with air circulation. I just did that this fall and i put the plywood door up in the winter. They are located in northern michigan. Any other suggestions?
    Thanks

    thanks for all the replies..
    Guess I gotta do it myself =( if I want to be sure it's done well...

    Besides the 6 mil clear plastic stuff, any one have other suggestions on what to use?

    BTW, we did redo all the downspouts to drain out to the street over the summer and have a french drain on the uphill side of the house that drains to the street, this year the crawl space is damp, but no standing water, like last year!
