Why a quote looks high (or low)
- Scope is often unknown until a camera inspection confirms it.
- Pipe material (PEX vs. copper) changes both cost and longevity.
- Permits, inspection and surface/landscape restoration may be excluded.
Get an apples-to-apples bid
- Ask whether trenchless or dig fits your situation and why.
- Confirm permits, inspection and restoration are included.
- Require a camera inspection so the scope is confirmed before work.
- Clarify who owns the city-side portion of the line.

How do you budget a major plumbing job?
Big plumbing jobs are unpredictable by nature — the method chosen and what's actually underground move the price more than anything else. Our editors weigh in.
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
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 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.
