- Clarify who owns the city-side portion of the line.
- Confirm permits, inspection and restoration are included.

How do you budget a major plumbing job?
Repipes and sewer lines are scope-driven — the method and what's underground decide the price. Our editors on the trade-offs.
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 diagnosis-first case
Never budget a sewer or repipe job from a guess. A camera inspection confirms the real scope and stops you paying for work you don't need — or being blindsided by work you do.
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.
Get the camera inspection first, weigh trenchless against the full restoration cost — not just the dig — and pick pipe material for your climate. The scope, not the brand, sets the price.
