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 material case
PEX is cheaper, faster and freeze-tolerant; copper costs more but lasts longer and some buyers prefer it. Match the material to your climate and how long you'll own the home.
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 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.
