Why whole-house repipe quotes vary — and how to compare them fairly
When two quotes for one project diverge by thousands, the cause is usually what each one includes, not markup — here's how to read the difference.
Why a quote looks high (or low)
- Scope is often unknown until a camera inspection confirms it.
- Trenchless vs. traditional dig is a major price difference.
- Permits, inspection and surface/landscape restoration may be excluded.
Get an apples-to-apples bid
- Require a camera inspection so the scope is confirmed before work.
- Compare pipe material on equal terms.
- Ask whether trenchless or dig fits your situation and why.
- Clarify who owns the city-side portion of the line.

Do I need a permit for whole-house repipe in Missoula?
The estimate above already covers the Plumbing permit Missoula generally requires for this job, so the $225 or so it costs won't land as a surprise.
What affects whole-house repipe cost the most?
Start with the fundamentals — replacing a home's water supply piping — typically swapping old galvanized or failing pipe for PEX or copper. 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
Pricing a sewer or repipe off a hunch invites two bad outcomes: paying to replace pipe that's fine, or missing the section that's actually collapsed. A camera run through the line settles the question before a single dollar is committed.
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 method case
Compare the two methods on the finished bill, not the excavation quote. Trenchless costs more to install yet skips restoring everything a trench destroys, while a conventional dig looks cheap right up until you price setting the yard right again.
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.
