Anyone here with experience making a crawlspace moisture-resistant (with plastic membranes or other means)?
Please read the question carefully before answering. Not looking for speculation or even helpful links to things I can find myself on the web. Looking for personal experience. (Funny anecdotes accepted as well.)
Reason for the question is a client with a damp crawlspace, dirt floor, and an overly-humid house. (Older house, vents installed, but no circulator, dehumidifier, etc.)
