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 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.
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.
