Sewer Line Repair in Mount Holly, NJ
The pipe between a house in Mount Holly and the public main is the owner’s, and on cast iron it is a run that loses capacity slowly rather than failing suddenly. There are 9,597 occupied homes here, and across all the housing the median build year is 1981 — the best single clue to what the pipe is made of and how it tends to fail.
In short
Cast iron on the house side with early PVC beyond it is the usual arrangement under Mount Holly properties, whose housing typically dates from 1981. Iron corrodes along the bottom of the pipe, so a survey looks at the invert rather than at the seams.

What went in the ground around 1981
A lateral laid in Mount Holly in that period is most likely cast iron on the house side and early PVC beyond it. Cast iron corrodes along the bottom of the pipe, so capacity is lost gradually rather than suddenly. More on cast iron laterals.
What a camera survey should settle here
On cast iron the recording should dwell on the bottom of the pipe, where corrosion channels and scale collect. The full picture on cast iron laterals.
Mount Holly is the 97th largest block of laterals we cover in New Jersey, carrying about 0.3% of the 3,313,875 homes on our NJ list, and its housing runs older than 19% of the NJ towns we route. Age concentration matters on a lateral: where a whole street went in one season, the failures arrive in one season too.
74% of homes here are owner-occupied — 11 points above the NJ figure. That matters more on a lateral than on almost any other pipe in the house: the run from the building to the main is the property owner’s to repair, and a landlord and a resident owner do not find that out at the same speed.
Median household income across Mount Holly ZIP codes is $107,165 — worth holding next to a repair that falls entirely on the property owner.

Before anyone digs in Mount Holly, get the run on camera — and ask what the bottom of the pipe looks like, because scale along the invert reads as a blockage. What the recording should show you.
