New Castle grew up on the Delaware River, and parts of town still sit on low ground behind colonial-era dikes. Streets near Battery Park and the land along the Broad Dike and Gambacorta Marsh are the first to see water when a storm tide meets heavy rain.
How river and tidal water gets in
Floodwater rarely arrives through the front door first. It comes up through the cellar floor, seeps through old brick walls and backs up floor drains as the ground fills.
- Groundwater rising through basement slabs and cellar floors
- Seepage through brick and stone foundation walls
- Surface water at low doors, window wells and garage slabs
- Floor drains pushing water back during storm tides

Why floodwater is handled as Category 3
Outside water carries soil, fuel, sewage and whatever it crossed on the way in. The flood crew treats it as black water: porous materials it touched come out, silt is shoveled and washed out, and every hard surface is cleaned and treated before drying starts.
Drying brick, slab and old framing
Brick cellars and slabs hold floodwater for days. The drying team uses desiccant and LGR dehumidifiers with air movers and logs readings daily. For flood coverage and maps, see FloodSmart and the FEMA flood maps page.

Tidal and River Flood Cleanup questions in New Castle, DE
Still dealing with tidal and river flood cleanup?
Floodwater keeps soaking into brick, slab and framing. The flood crew works around the clock once the water drops.
Is tidal floodwater really Category 3?
Yes. Floodwater from outside carries soil, fuel and sewage, so it is handled as black water from the start.
Does homeowners insurance cover river flooding?
Most homeowners policies exclude flood. Flood coverage usually comes from a separate flood policy. Check with your own insurer.
Why does the cellar take so long to dry?
Brick and stone hold water deep in the masonry. Desiccant dehumidifiers and daily readings bring it down over several days.
Do walls have to be cut after a flood?
Drywall touched by floodwater is cut above the water mark. Plaster may be cleaned and dried in place depending on readings.
Can I pump the basement myself?
Pumping a flooded basement too fast while the ground outside is saturated can stress foundation walls. Wait for outside water to drop.
What about the furnace and water heater?
Appliances that sat in floodwater need a qualified technician's check before use.
