- Permits, inspection and surface/landscape restoration may be excluded.
Get an apples-to-apples bid

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 diagnosis-first case
The estimate is only as honest as the inspection behind it. Push a camera down the line first and the scope becomes a documented fact — no padding for problems that aren't there, no ambush once the trench is open.
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 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.
Underground surprises, not the plumber's brand, are what blow up a repipe or sewer budget. A camera inspection pins down the scope, a trenchless-versus-dig comparison should count the restoration bill and not just the trench, and the pipe material ought to suit your climate.
