DampDeck combines factual geography with a source-led state moisture profile. Because states can span multiple climate regions, the profile is orientation rather than a city-level climate claim.

Cold / humid-season moisture context

Winter condensation on cold surfaces can coexist with basement seepage, roof leaks and warm-season humidity. Air sealing or weatherization without adequate ventilation can also change indoor moisture behavior.

How to read this: this is state-level orientation, not a claim that every home in Iowa has the same climate, construction or moisture risk. US states can span multiple climate regions. Diagnose the actual water pathway first.

Guidance basis: US EPA moisture and mold control guidance; US Department of Energy Building America climate-region framework. Reviewed September 2026.
