Question do we need barrier for crawl to stop window condensation

HI
this past month we started getting water dripping off the windows especially when the blinds were closed at night. last year we had this problem when our hot water heater broke and caused mold problems inside we took care of that with a mold remediator and it was fine until a month ago. we were told at our inspection we should put a 6 mil moisture barrier in the crawl. Right now it is sand with plastic underneath. we went down there when discovered the windows were wet again the sand was damp/wet no reason for it. We put a heater & demumidifier down in crawl seemed to dry it up a bit & help windows no water in dehumidifier except maybe a 1/4 cup. what can we do to stop this problem. will the plastic help alone and or shouold we also insulate how & where. please help
thanks

Window condensation can be an indication of too much moisture in the home. Moisture barriers (plastic on the ground) is an established method of controlling the amount of moisture that enters the home. What this explicitly implies is there are a variety of sources of moisture and just as many methods to control the amount of moisture that the home may have.

For example, all materials absorb and expel moisture. some materials absorb faster arid expel slowly moisture. While others do the exact opposite. If your water heater saturated the wood surrounding it, this wood would expel the moisture slowly. This would provide the moisture in the house for the condensation on the windows.

Now this may or may not be the cause for the condensation on your windows, but by what you describe, it seems more likely to be the cause than having a 6 mil plasic sheet over the sand in your crawl space.

sorry about the 2nd post, there is no insulation in crawl, my husband cleaned out all the builders junk & put down the 6mil plastic he hasn't taped it yet but the 1st. night no moisture on windows thanks for that help you said to keep vents shut. To keep house warmer should we insulate walls & seal vents for good? this won't cause moisture problem in future will it. thanks again for your help
