When to Repipe Your Austin Home — Signs & Costs

Several signs indicate that your home's plumbing has reached the point where repiping is worth considering:

Recurring leaks in multiple locations. One leak is a repair. Two leaks in different locations within a year is a pattern. Three leaks is a system telling you the pipe material is failing throughout — not just at the spots you've fixed.

House-wide water pressure drop. If pressure has dropped at every fixture in the house — not just one faucet — the supply lines themselves are restricting flow. Galvanized pipe corrodes from the inside, and the corrosion buildup narrows the pipe interior over years, reducing flow throughout the system.

Discolored water. Rust-colored or brown water from hot water fixtures indicates corrosion inside the supply lines or water heater. If it clears after running the tap for a minute, the corrosion is in the supply lines, not the water heater.

Visible corrosion on exposed pipes. Check under sinks, in the utility room, and anywhere pipes are exposed. Blue-green staining on copper indicates corrosion at fittings. Orange-brown flaking on galvanized pipe indicates active rust.

A plumber or inspector identified galvanized pipe. If you've been told your home has galvanized supply lines, that's the most direct indicator. Galvanized pipe has a finite service life, and in Austin's hard water environment, that life is shorter than in softer water areas.

Galvanized steel pipe was the standard supply line material in homes built before the 1970s. It was coated with zinc to resist corrosion — but that zinc coating wears away over decades, and the steel underneath corrodes from the inside out.

The corrosion process does two things: it narrows the pipe interior (reducing water pressure) and it creates rough, pitted surfaces that trap scale from Austin's hard water. The combination of corrosion and scale buildup accelerates the narrowing and eventually causes complete blockages or failures at fittings.

East Austin's renovation market is where we see this most frequently — bungalows and 1970s homes being updated often have galvanized supply lines that haven't been touched since original construction. The renovation process exposes the pipe condition, and homeowners face a choice: repipe now as part of the renovation, or repipe later after the walls are closed up again. Doing it during renovation is almost always less expensive.

Galvanized pipe in Austin homes that's over 40 years old and hasn't been replaced is past its expected service life. If your home has it, a repiping assessment is worth scheduling.

Whole-house repiping replaces the supply lines throughout your home — the pipes that carry water from the main shutoff to every fixture, appliance, and hose bib. It does not replace drain lines (a separate system).

The process involves accessing the existing supply lines — which run inside walls, under floors, and through the attic in some Austin homes. Access holes are cut in drywall where needed. New PEX or copper supply lines are run to every fixture. The old pipe is removed or abandoned in place depending on location.

We work in phases to restore water service each day. You won't be without water overnight. After the new lines are in place, a pressure test confirms the system before we close the walls.

Drywall patching is typically not included in a repiping quote — that's usually handled separately by a drywall contractor or the homeowner. Ask your plumber what's included in the scope.

Whole-house repiping typically takes 1–3 days depending on the size of the home and the complexity of the existing plumbing layout. A 1,200 square foot bungalow with a straightforward layout takes less time than a 2,500 square foot two-story home with an attic-mounted water heater and multiple bathrooms.

We work in phases to restore water service each day. The final day includes a pressure test of the complete system and a walkthrough with the homeowner to confirm everything is working.

Plan for some disruption during the work — access holes in walls, water shut off during portions of the work, and noise from the work itself. We minimize disruption where possible and clean up the work area each day.

Whole-house repiping in Austin typically runs $4,000–$12,000 depending on home size, pipe material, and complexity. Here's what drives the range:

Home size. A 1,000 square foot home has fewer linear feet of supply line than a 3,000 square foot home. More pipe, more labor, higher cost.

Pipe material. PEX is less expensive than copper for both material and labor. Copper is more expensive but preferred by some homeowners and required in some situations.

Layout complexity. A single-story slab home with a simple layout costs less than a two-story home with an attic water heater and complex routing.

Access difficulty. Homes where supply lines run through finished walls and ceilings require more drywall access work than homes with accessible crawl spaces or open framing.

Permit requirements. Major repiping projects may require a permit from the City of Austin. Permit costs typically run $100–$300 and are part of the total job cost.

We provide a written scope and price after assessing the home — not before we've seen the actual pipe layout and condition. Call us to schedule a repiping assessment.
