Which page first?
Standing water after storms points to drainage before anything else, so read the code guide's section on drains. Torn or missing plastic means the vapor barrier page. A musty smell with dry-looking plastic usually means the air needs drying, which is the dehumidifier page. Insulation lying on the ground belongs on the insulation page. If you plan to seal the whole space, the price list shows how the parts add up.
