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 diagnosis-first case
Pricing a sewer or repipe off a hunch invites two bad outcomes: paying to replace pipe that's fine, or missing the section that's actually collapsed. A camera run through the line settles the question before a single dollar is committed.
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
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.
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.
