How do you budget a major plumbing job?
Sewer lines and repipes don't come with a sticker price — the installation method and the condition of the ground move the number more than any material choice.
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 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 material case
PEX installs faster, costs less, and flexes instead of splitting when a line freezes — a real edge in cold zones. Copper carries a higher price and a longer service life, and some buyers still read it as the quality choice; let your climate and how long you'll own the home make the call.
The number one rule for a big plumbing job: confirm the scope with a camera before you price anything. From there, weigh trenchless against total restoration cost and pick materials suited to your climate.
