- Scope is often unknown until a camera inspection confirms it.
Get an apples-to-apples bid

How do you budget a major plumbing job?
Plumbing budgets for repipes and sewer lines hinge on two unknowns — the install method and the ground itself. Our editors break down the trade-offs.
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.
The method case
Trenchless repair costs more per foot but saves your driveway, landscaping and the restoration bill. Traditional dig is cheaper upfront only if there's little to tear up and rebuild.
Scope, not brand, is what sets a plumbing price. Confirm it with a camera inspection, compare trenchless against the full cost of a dig — landscaping included — and match pipe material to your climate.
