Sewer Line Repair in North Hampton, NH
The pipe between a house in North Hampton 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 2,057 occupied homes here, and across all the housing the median build year is 1985 — 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 North Hampton properties, whose housing typically dates from 1985. 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 1985
A lateral laid in North Hampton 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.
North Hampton is the 53rd largest block of laterals we cover in New Hampshire, carrying about 0.5% of the 436,947 homes on our NH list, and its housing runs older than 26% of the NH towns we route. Age concentration matters on a lateral: where a whole street went in one season, the failures arrive in one season too.
89% of homes here are owner-occupied — 18 points above the NH 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 North Hampton ZIP codes is $136,170 — the relevant figure for a job no insurer and no utility is going to split.

Before anyone digs in North Hampton, 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.
