Expert Plumbing Services in Washington, District of Columbia

Tens of thousands of District homes still take water through lead service lines. DC Water replaces lead lines free when encountered during capital projects, and the Lead Pipe Replacement Assistance Program can cover private-side replacement for qualifying owners — with a voluntary path for those who prefer not to wait. We identify your service material, explain where you stand, and perform full replacements including the private side, coordinated properly with the public side.

A century of water has thinned the supply lines in most old rowhouses — galvanized rusting from within, copper developing pinholes. Fading pressure, brown water after sitting, mysterious damp spots in party walls: the end-of-life pattern. We pressure-test to map the damage and repipe in full runs, because patching century-old pipe is a short story with an expensive ending.

In combined-sewer neighborhoods, a heavy storm can fill the city main and push water back toward the lowest drains in the house — the classic DC basement backup. Backwater valves stop the reverse flow; sump and ejector systems handle what gets in anyway. We install and service the full defense and verify it before storm season, not during.

Rowhouse laterals run short distances under small yards and tree-lined streets — and the old clay pipe has joints that roots were made to exploit. Backups that return after every clearing point underground. We cable and camera, show you the intrusion, and renew the lateral — trenchless where the tight urban lot allows.

Rowhouse additions, enclosed porches, basement kitchens and exterior-wall runs freeze in a hard Mid-Atlantic winter — and the thaw reveals the split. We thaw safely, repair with proper materials, and insulate and reroute the vulnerable sections so the next cold snap is uneventful.

Below-grade bathrooms and laundries depend on ejector pumps; English basements depend on sump pumps. A stuck float or burned-out motor announces itself at the worst moment. We service and replace both systems, verify check valves and alarms, and add battery backup where outages threaten.

The vertical stacks and building sewers in old rowhouses are cast iron near the end of its run — scaling inside, rusting through, leaking into party walls. Slow drains throughout, sewer odors, damp plaster: the pattern. Camera and inspection show the true condition; trenchless or targeted renewal fixes it without gutting the house.

In dense rowhouses, a leak can hide in a party wall or under a slab for months — showing only as a climbing water bill or a damp patch. Electronic listening and thermal imaging find it without opening half the house. We pinpoint, open once, repair, and verify.
