Why a quote looks high (or low)
- Trenchless vs. traditional dig is a major price difference.
- Permits, inspection and surface/landscape restoration may be excluded.
- Pipe material (PEX vs. copper) changes both cost and longevity.
Get an apples-to-apples bid

- Confirm permits, inspection and restoration are included.

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
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 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.
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.
