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
Compare the two methods on the finished bill, not the excavation quote. Trenchless costs more to install yet skips restoring everything a trench destroys, while a conventional dig looks cheap right up until you price setting the yard right again.
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
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.
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.
