Sewer Line Repair in Cohasset, MA
In Cohasset the sewer lateral — the run from the house to the public main — belongs to whoever owns the property, not to the utility. There are 3,109 occupied homes here, and across all the housing the median build year is 1964 — the best single clue to what the pipe is made of and how it tends to fail.
In short
Two materials are in play beneath a typical Cohasset property, whose housing dates from about 1964: clay, and the bituminized fiber laid next to it. The two fail in quite different ways, and a camera survey is what separates them.

What went in the ground around 1964
A lateral laid in Cohasset in that period is most likely Orangeburg or cast iron, with clay still going in at some depths. Which of the three you have is not something the build year can settle on its own. More on Orangeburg pipe.
What a camera survey should settle here
Three materials were going in the ground at once in these years, so the survey is identifying the pipe before it diagnoses anything. The full picture on Orangeburg pipe.
Cohasset is the 141st largest block of laterals we cover in Massachusetts, carrying about 0.2% of the 1,695,114 homes on our MA list, and its housing runs older than 56% of the MA towns we route. Age concentration matters on a lateral: where a whole street went in one season, the failures arrive in one season too.
83% of homes here are owner-occupied — 23 points above the MA 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 Cohasset ZIP codes is $187,060 — the relevant figure for a job no insurer and no utility is going to split.

Before anyone digs in Cohasset, get the run on camera — and ask what the pipe is actually made of, because the build year cannot settle it at this age. What the recording should show you.
