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
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.
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.
