Sorry to hear that Gofergal. I had a leak in our new house and the builder treated the carpets immediately. Mold build up can cause health problems (especially black mold) and it needs to be taken care of immediately. The builder steamed cleaned the carpet and applied an anti mold agent. I'm not sure if the dealer is going to go that far to fix your leak. Try looking at http://www.traskresearch.com/oxymold.htm ...good luck!
