How do you budget a major plumbing job?
Plumbing budgets for repipes and sewer lines hinge on two unknowns — the install method and the ground itself. Our editors break down the trade-offs.
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 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.
Get the camera inspection first, weigh trenchless against the full restoration cost — not just the dig — and pick pipe material for your climate. The scope, not the brand, sets the price.
