Is the price difference a dealbreaker?
A 11% spread (roughly $700) is significant enough to plan around, but not fixed — off-peak timing and sharper bidding in Houston typically recover some of it.

What plumbing pros earn in each metro
About 60% of a sewer line replacement bill goes to labor, so wage differences between these two metros matter more than almost anything else. These are real, government-sourced (BLS OEWS) installer wages, not estimates.
McAllen-Edinburg-Mission metro · about 22% below the US average installer wage.

Cheapest time for sewer line replacement in either city
True emergencies pay full rate. But planned projects — a repipe or sewer-line replacement — can be scheduled in a slower month for slightly better pricing and more attentive crews.
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 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.
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 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 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.

Should I choose where to live based on sewer line replacement cost?
Probably not. Yes, $700 is a real gap, but it's a one-time cost you can partly offset in Houston with off-season timing and tighter bids. Long-term factors like energy prices and home condition matter more than this one number.
