How much should this gap actually matter?

Cheapest time for sewer line replacement in either city
An actual emergency always pays full rate — there's no negotiating room. But a planned repipe or sewer-line job can be timed to a slower month, where crews have more attention to give and a little more room on price.
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 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 material case
In freeze-prone regions PEX has the advantage: cheaper, quicker to run, and forgiving when temperatures drop. Copper asks for more up front but outlasts it and can nudge resale with certain buyers. The tiebreaker is your weather and your timeline in the house, not a blanket rule.
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.
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.
