Why a quote looks high (or low)
- Permits, inspection and surface/landscape restoration may be excluded.
- Pipe material (PEX vs. copper) changes both cost and longevity.
- Scope is often unknown until a camera inspection confirms it.
Get an apples-to-apples bid

- Compare pipe material on equal terms.
- Require a camera inspection so the scope is confirmed before work.

Budget about $250 for the Plumbing permit most Ann Arbor jobs like this require — and note it already sits inside the estimate above, not on top of it.
What affects whole-house repipe cost the most?
Replacing a home's water supply piping — typically swapping old galvanized or failing pipe for PEX or copper. That's the baseline — the price moves from there. Your cold climate zone plays a part, but equipment/material grade, the size and complexity of the home, and local labor rates weigh in just as heavily.
How do you budget a major plumbing job?
The price of a repipe or sewer replacement is set less by who does the work than by how it's installed and what the crew finds under the yard.
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 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.
Confirm the scope with a camera before anyone quotes a number, then judge trenchless against a dig by its total cost with the yard restored — and spec PEX or copper to match your winters. Do that and the price tracks the actual job, not a label.
