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.
Mixed-humid moisture context
Homes can face both warm-season humidity and cold-surface condensation, while heavy rain, grading and foundation drainage can create separate water-entry problems.
How to read this: this is state-level orientation, not a claim that every home in Delaware has the same climate, construction or moisture risk. US states can span multiple climate regions. Diagnose the actual water pathway first.
