Serving Mercersburg &
Western Franklin County

Mercersburg is one of Franklin County's most storied communities — a small borough with deep American history, a tight-knit community, and homes that span from 18th-century structures to modern builds along the outskirts. It sits in the far western corner of Franklin County, close to both the Maryland and West Virginia borders.

Out here, nearly every property draws from a private well. The groundwater in western Franklin County is heavily influenced by the area's limestone and shale geology — producing hard, mineral-rich water that puts real stress on water heaters, pressure tanks, and fixtures over time. We see the effects on almost every job we run in this area.

Keystone PHS serves Mercersburg and the surrounding western Franklin County communities. Same flat rate any time of day, upfront pricing before we start anything, and we never leave a job unfinished. Call us — we'll be there.

Historic Borough HousingMercersburg's older homes have unique plumbing challenges — aging supply lines, original fixtures, and systems that need experienced, careful updating.
Western Franklin County WellsWell systems are nearly universal in Mercersburg's surrounding townships — pressure tank health and pump performance are critical.
Hard Mineral WaterLimestone and shale geology in western Franklin County produces very hard water that scales water heaters and damages appliances.
Close to Our Coverage AreaMercersburg is well within our service zone — same-day response is the standard, not the exception.

Common Questions from
Mercersburg, PA Customers

Real questions we hear from homeowners in Mercersburg and Franklin County, answered honestly.

Older Mercersburg homes — particularly those in the historic downtown — often have galvanized steel supply pipes that have been corroding from the inside for decades, reducing water pressure and eventually failing. We also frequently see original shut-off valves that no longer actually shut off, and water heaters that have failed prematurely because of the area's hard water. We handle all of it.
Yes — the majority of properties in and around Mercersburg and the surrounding townships are on private wells. Municipal water serves the borough core, but most of the surrounding area is on well systems. We service both, and we're very familiar with the well conditions in western Franklin County.
