Harbor-area groundwater
Canton and Federal Hill near the harbor have shallow groundwater and fill soils that keep basements damp.
Rowhouse shared walls
Party walls carry water from one house to the next; one neighbor's leak can show up in another's basement.
Brick and stone deterioration
Soft historic brick and lime mortar erode with moisture and need careful repointing.
Sewer backups in storms
Older sewer systems can surcharge in heavy rain; backwater valves protect floor drains.
