How do you budget a major plumbing job?
Big plumbing jobs are unpredictable by nature — the method chosen and what's actually underground move the price more than anything else. Our editors weigh in.
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
The estimate is only as honest as the inspection behind it. Push a camera down the line first and the scope becomes a documented fact — no padding for problems that aren't there, no ambush once the trench is open.
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.
