Venting a crawlspace comments

Yesterday, I was speaking with a home owner in Nanaimo, and he was trying to figure out why his crawlspace was still musty smelling, even after he increased his venting (as recommended by his neighbour). Subsequently, he placed batt insulation in the ceiling of the crawlspace to keep his floors from becoming too cold. And the musty smell was still there. This is just another example of how bad advice can cause a homeowner to waste money installing products that don't work. We're off to inspect his crawlspace next week....
