Plumbing Repair vs Replacement: What to Expect

The Hidden Cost Behind Your Walls

Plumbing issues strike fear into the hearts of homeowners because the damage is often invisible until water starts pouring through a ceiling drywall. While fixing a leaky faucet is a cheap Saturday project, addressing degrading pipes in an older home requires major capital. When do you stop patching and bite the bullet on a full repipe?

The Case for Repairing (Spot Fixes)

If your home was built after 1990 and utilizes copper or early PEX tubing, isolated leaks are usually just bad joint connections or frost damage. A licensed plumber will typically charge a standard service call fee ($150-$250) plus an hourly rate to cut out the bad section and solder/crimp a new piece in.

Spot repairs are smart if the rest of your system is sound. A $400 repair bill is infinitely better than an $8,000 repipe.

The Case for Repiping (Full Replacement)

You absolutely must consider a full whole-house repipe if your home was built between 1950 and 1980 and still utilizes Galvanized Steel Pipes or defective Polybutylene tubing. Galvanized pipes literally rust from the inside out, choking water pressure and eventually bursting. Polybutylene degrades and fractures without warning.

2026 Repiping Costs

A full whole-house repipe requires tearing open your drywall to access the vertical stacks. The national average in 2026 for a 2-bathroom, 1,500 sq ft house ranges from $4,500 to $8,000 using modern PEX tubing.

If you demand copper piping instead of PEX, expect the price to jump to $8,000 to $12,000+ due to the massive increase in raw material costs and the labor required to solder hundreds of joints.

The "Hidden" Drywall Bill

Here is the shocker most homeowners do not realize: plumbers do not repair drywall. They will cut massive 3-foot squares in your living room walls to pull new PEX pipes through the studs. Once the county inspector signs off on the plumbing, the plumbers leave. You must then hire a separate drywall contractor and a painter to patch all those holes, which frequently adds another $1,500 to $2,500 to the total project cost.
