How do you budget a major plumbing job?
Sewer lines and repipes don't come with a sticker price — the installation method and the condition of the ground move the number more than any material choice.
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 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.
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.
Skip the camera and you're budgeting a repipe or sewer line on guesswork. Get the inspection, compare trenchless against the dig on what it costs to make the property whole again, and choose pipe — PEX or copper — for the temperatures it'll live in.
