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 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 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.
Scope, not brand, is what sets a plumbing price. Confirm it with a camera inspection, compare trenchless against the full cost of a dig — landscaping included — and match pipe material to your climate.
