How do you budget a major plumbing job?
Plumbing budgets for repipes and sewer lines hinge on two unknowns — the install method and the ground itself. Our editors break down the trade-offs.
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.
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.
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.
