How do you budget a major plumbing job?
Repipes and sewer lines are scope-driven — the method and what's underground decide the price. Our editors on the trade-offs.
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 material case
PEX installs faster, costs less, and flexes instead of splitting when a line freezes — a real edge in cold zones. Copper carries a higher price and a longer service life, and some buyers still read it as the quality choice; let your climate and how long you'll own the home make the call.
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.
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.
