How do you budget a major plumbing job?
There's no fixed price for a repipe or sewer job until you know the method and what's below the yard. Our editors on how to think about the scope.
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.
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 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.
