One verified local quirk shapes our work: San Francisco's Hetch Hetchy water is famously soft Sierra snowmelt, but its very low alkalinity makes it mildly aggressive to metal pipe. In a brand-new copper system that's harmless; in a 110-year-old galvanized system in the Richmond District, the Sunset District, Noe Valley, or Bernal Heights, it accelerates the internal corrosion already underway.
Victorian & Edwardian Home Plumbing Specialists
Old-house plumbing fails in predictable ways: galvanized supply lines that have narrowed to a pencil's width with rust, original cast-iron drains with bellies and cracks, lead-bent closet flanges, and fixtures mounted to framing no modern manual recognizes. We repipe with modern materials, rebuild drain systems, and replace fixtures while preserving the period character of your home.
We also handle the era-specific surprises — like finding a long-abandoned gas line, cloth-wrapped wiring near your pipes, or a sewer lateral made of materials no one manufactures anymore.
Sewer Lateral Replacement for Aging City Lines
Your sewer lateral runs from your home to the city main under the street, and in San Francisco that often means a century-old clay or cast-iron pipe under a sidewalk, a mature street tree, and a very expensive stretch of pavement. Roots love the joints in old clay pipe, and shifting fill soils crack them.
We camera-inspect the line first, then recommend trenchless replacement or lining wherever the layout allows — which avoids tearing up sidewalks and keeps the city's permit process simpler. When open trench is unavoidable, we handle the excavation and restoration properly.
24/7 Emergency Service in a City of Old Pipes
Burst risers in apartment buildings, sewage backing up into garden-level units, water heaters failing in cramped closets — San Francisco emergencies come with access challenges, and our techs are used to them. We serve the Richmond, the Sunset, the Mission, Noe Valley, Haight-Ashbury, Bernal Heights, and the Excelsior around the clock.
Every job starts with upfront pricing, and we explain old-house options in plain language before any work begins.
Frequently Asked Questions
Should I repipe my Victorian's galvanized lines?
If your water pressure is low, the water runs discolored, or you're opening walls for a remodel anyway, repiping is usually the right call. Galvanized pipe has a 40–60 year life and most San Francisco installations are far beyond it — replacing it now prevents the emergency later.
How do I know if my sewer lateral needs replacement?
Recurring backups, gurgling drains, soggy spots in the yard, or roots found during a cleaning all point to a failing lateral. A camera inspection shows the pipe's true condition and lets us quote trenchless options accurately.
Is San Francisco's water hard on pipes?
It's soft, not hard — but its low mineral content and low alkalinity make it slightly aggressive to old metal pipe, speeding corrosion in aging galvanized systems. Modern copper and PEX handle it fine, which is another reason repiping old stock pays off.
Do you work in apartment buildings and flats?
Yes — much of our San Francisco work is in multi-unit buildings, in-law units, and TICs. We coordinate with building access requirements and keep common-area disruption to a minimum.
