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 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.
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.
