Keystone Plumbing Co.

Keystone Plumbing Co. has served West Philadelphia since 2003, developing specific expertise in the Victorian-era and early 20th century rowhouses that characterize the Cedar Park, Spruce Hill, and Cobbs Creek neighborhoods. These homes were designed around steam heat and gravity drain systems — technologies that require a different skill set than modern plumbing. Steam radiator repair and balancing is something few plumbers in Philadelphia will touch. We've invested in the training and tooling to diagnose steam system problems — banging pipes, cold radiators, water hammer, boiler flooding — and we understand the physics of one-pipe versus two-pipe systems. Repiping old galvanized steel supply lines to copper or PEX is a frequent project in our service area. We work efficiently in occupied rowhouses, completing most repipes in two days with a planned water-off window of under four hours.
