How much should this gap actually matter?
That 4% gap is small — for sewer line replacement it's usually less than the spread between two local contractors' quotes, so the metro matters far less than who you hire and when you buy.

What plumbing pros earn in each metro

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?
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 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 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
Trenchless repair costs more per foot but saves your driveway, landscaping and the restoration bill. Traditional dig is cheaper upfront only if there's little to tear up and rebuild.
Skip the camera and you're budgeting a repipe or sewer line on guesswork. Get the inspection, compare trenchless against the dig on what it costs to make the property whole again, and choose pipe — PEX or copper — for the temperatures it'll live in.
