Why a quote looks high (or low)
- Pipe material (PEX vs. copper) changes both cost and longevity.
- Scope is often unknown until a camera inspection confirms it.
- Permits, inspection and surface/landscape restoration may be excluded.
Get an apples-to-apples bid
- Ask whether trenchless or dig fits your situation and why.
- Clarify who owns the city-side portion of the line.
- Confirm permits, inspection and restoration are included.
- Require a camera inspection so the scope is confirmed before work.

How do you budget a major plumbing job?
Repipes and sewer lines are scope-driven — the method and what's underground decide the price. Our editors on 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.
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.
