- Permits, inspection and surface/landscape restoration may be excluded.
Get an apples-to-apples bid
- Require a camera inspection so the scope is confirmed before work.
- Compare pipe material on equal terms.
- Clarify who owns the city-side portion of the line.
- Ask whether trenchless or dig fits your situation and why.

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 method case
Trenchless runs a higher per-foot rate, but the savings hide in what you never have to rebuild — no torn-up driveway, no re-sodded lawn, no ripped-out patio. Open-cut digging only wins on price when there's almost nothing on top of the line to put back.
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.
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.
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.
