In Capitol Hill, 1860s-1920s construction plus one of the largest historic rowhome districts in the US; galvanized, cast iron, lead services changes whether a slow drain is a local clog, a clay lateral with roots, or a supply material that is failing house-wide. Generic “plumber near me” pages skip that — we do not.

Utility note: Clay laterals under brick sidewalks, cast-iron stacks, and winter freeze on exposed runs are everyday DC patterns.
DC plumbing problems we see weekly
- Galvanized supply pipes from the 1920s–50s — rusted shut from the inside, killing water pressure one year at a time.
- Lead service lines — DC Water is replacing them block by block; we test, advise, and coordinate the private-side replacement.
- Original cast-iron stacks in row homes — 80+ years old and often one flush away from a very bad Saturday.
- Tree roots in clay sewer laterals — DC's street trees have opinions about your sewer line.
- Combined-sewer backups in low-lying blocks — backwater valves matter in Bloomingdale basements.
- Condo riser and shutoff coordination — we handle building management and access rules so you don't have to.
- Basement and cellar conversions with undersized ejector pumps — that apartment needs more than optimism to drain uphill.
