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 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
In freeze-prone regions PEX has the advantage: cheaper, quicker to run, and forgiving when temperatures drop. Copper asks for more up front but outlasts it and can nudge resale with certain buyers. The tiebreaker is your weather and your timeline in the house, not a blanket rule.
The method case
Trenchless runs a higher per-foot rate, but the savings hide in what you never have to rebuild — no torn-up driveway, no re-sodded lawn, no ripped-out patio. Open-cut digging only wins on price when there's almost nothing on top of the line to put back.
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.
