Rainfall, Storms & Seasonal Moisture in Washington, DC

Washington, DC experiences seasonal rainfall patterns and storm events — and when soil around a foundation gets saturated works into structures through any pathway available. The process is cumulative — but the damage it causes get more expensive the longer they continue.

Foundation Types Common in Washington, DC Properties

Clay-heavy soils, common in many Washington, DC communities, retain moisture longer and create sustained lateral pressure against foundation walls.

Washington and surrounding Washington, DC communities feature housing ages and foundation types. Properties built decades ago throughout Washington often lack adequate below-grade moisture protection. Our Washington, DC technicians know the failure patterns specific to the housing stock in this part of DC.
