How do you budget a major plumbing job?
The price of a repipe or sewer replacement is set less by who does the work than by how it's installed and what the crew finds under the yard.
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.
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.
Start with a camera inspection so the scope is fact, not a guess. Compare trenchless against the dig's full restoration bill, not just the excavation, and choose pipe material for your climate.
