What kind of homes and basements does Wilmington have?
Trolley Square, Little Italy and Browntown have many early 20th-century brick rowhouses with brick or stone basements. The Highlands and Wawaset Park have larger homes on sloped lots. Areas near the rivers are low, with shallow groundwater.
What causes basement and foundation problems in Wilmington?
Rowhouse basement seepage
Shared brick walls and old drains let water into rowhouse basements during long rains; interior drainage is typical.
River-area groundwater
Low blocks near the Christina can take water through the floor when groundwater rises.
Sloped-lot runoff
Northern neighborhoods on hills send runoff to uphill walls and window wells.
Brandywine valley slopes
Homes on the hills above the Brandywine take steady runoff during long rains. Curtain drains uphill, clean gutters and downspouts piped well away from the house cut the volume of water reaching the foundation.

What do Wilmington homeowners ask most?
Do Delaware contractors need a license?
Contractors need a state business license from the Division of Revenue, and nonresident contractors must register and post a bond. The city issues building permits.
Why does my Wilmington rowhouse basement leak along the party wall?
Water often travels along shared walls from neighbors' downspouts or yards. Interior drainage on your side and talking with neighbors about gutters both help.
Do Wilmington rowhouses need a sump pump?
Not always. If water enters only during heavy rain through one wall, gutter and grading fixes may be enough. If the floor gets wet from below or water appears in several places, an interior drain to a sump is the more reliable fix.
