What affects sewer line replacement cost the most?
Replacing the main sewer line from the home to the municipal connection (trenchless or traditional excavation). From there, a handful of specifics push the final number up or down.

How do you budget a major plumbing job?
There's no fixed price for a repipe or sewer job until you know the method and what's below the yard. Our editors on how to think about the scope.
The material case
In freeze-prone regions PEX has the advantage: cheaper, quicker to run, and forgiving when temperatures drop. Copper asks for more up front but outlasts it and can nudge resale with certain buyers. The tiebreaker is your weather and your timeline in the house, not a blanket rule.
The method case
Compare the two methods on the finished bill, not the excavation quote. Trenchless costs more to install yet skips restoring everything a trench destroys, while a conventional dig looks cheap right up until you price setting the yard right again.
The diagnosis-first case
The estimate is only as honest as the inspection behind it. Push a camera down the line first and the scope becomes a documented fact — no padding for problems that aren't there, no ambush once the trench is open.
Confirm the scope with a camera before anyone quotes a number, then judge trenchless against a dig by its total cost with the yard restored — and spec PEX or copper to match your winters. Do that and the price tracks the actual job, not a label.
