For water damage in Downtown Wilmington (ZIP 19801), call the 24/7 line to get a local restoration crew dispatched for extraction, drying and repairs. Older rowhomes in Quaker Hill, the East Side and Southbridge often have stone foundations, cast-iron drains and shared walls, and low blocks near the Christina drain into combined sewers, so sewer backups and leaks that spread next door are common.
ZIP code 19801 is the center of Wilmington: the Market Street and Rodney Square business district, the Riverfront along the Christina River, and older residential neighborhoods such as Quaker Hill, Trinity Vicinity, West Center City, the East Side and Southbridge. The city’s PO box and business ZIP codes, including 19850 and 19899, are based here as well.
Most homes downtown are brick rowhomes built from the mid-1800s into the early 1900s. They often still have stone or brick foundation walls, cast-iron drain stacks, galvanized supply lines and plaster walls, and every one of them shares a party wall with a neighbor. A leak that starts in one house rarely stays there for long.
The low ground near the Christina is the other factor. Southbridge and parts of the East Side sit close to river level, and the oldest parts of the city are served by a combined sewer system that carries stormwater and wastewater in the same pipes. During a heavy downpour, water has fewer places to go, and basements are where it ends up.

What Causes Water Damage in Downtown Wilmington & Riverfront?
Shared Party Walls
Rowhomes and converted apartments share walls, joists and sometimes roofs, so one failed supply line can reach the house next door.
Original Plumbing
Cast-iron stacks, galvanized supply pipe and old clay laterals crack and corrode with age, and the leaks usually start inside walls.
Low Ground Near the Christina
Southbridge and riverfront blocks sit close to river level, so storm runoff and high water reach basements and ground floors first.
Combined Sewer Backups
Older blocks drain into combined sewers, and heavy rain can push wastewater back up through basement floor drains.
Rowhomes Need a Careful Approach
Drying a 120-year-old brick rowhome isn’t the same as drying a 1990s condo. Plaster on lath holds moisture longer than drywall, old-growth heart pine floors can often be dried flat instead of replaced, and stone foundation walls wick groundwater for days. Before anything is torn out, ask the restoration team how they’ll dry the historic materials and how they’ll check the neighboring wall and the unit below.
