Is the price difference a dealbreaker?

Cheapest time for sewer line replacement in either city
You can't time an emergency, but you can time a repipe or sewer job — and doing it in a slower month means slightly better pricing and a crew with the bandwidth to do it right.
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 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 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 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.
Scope, not brand, is what sets a plumbing price. Confirm it with a camera inspection, compare trenchless against the full cost of a dig — landscaping included — and match pipe material to your climate.
