Crawl space encapsulation seals the dirt under your house so damp stops rising into the rooms above. Bare soil gives off water all day. The stack effect (opens in a new tab) then pulls about 40% of that air up into your ground floor, which is the same path the EPA describes for indoor air quality (opens in a new tab).
Akron makes it worse both ways. Summer air pulled through open vents hits cool pipes and turns to water. January air through those same vents freezes your supply lines and pushes the heating bill up. Wet fiberglass insulation has already stopped working by then.
We lay a 20-mil liner across the floor and up the walls, sealed at every seam and post. The rim joists get sealed and insulated. Then a dehumidifier holds the air under 55% damp all year. If the wood down there has already gone soft, crawl space repair comes first, and the seasonal walkthrough tells you which one you need.
