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 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
Pricing a sewer or repipe off a hunch invites two bad outcomes: paying to replace pipe that's fine, or missing the section that's actually collapsed. A camera run through the line settles the question before a single dollar is committed.
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.
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.
