If you own an older home in Evansville — especially in neighborhoods like Riverside, the Old Siegel House area, or anywhere near downtown — there's a decent chance your plumbing is working against you. Many homes built in Vanderburgh County before the 1980s still have their original galvanized steel supply lines. Those pipes were built to last 40 to 50 years, and most of them are well past that mark now.
A whole house repipe replaces every supply line in your home at once. It's not a small project, but it's often the right one. Here's how to tell if you need one.
Warning Signs Your Home Needs a Repipe
Discolored or Rusty Water
If you turn on the tap and see brown, yellow, or reddish water — especially first thing in the morning — your pipes are corroding from the inside. Galvanized steel reacts with minerals in Evansville's water over decades, and that rust ends up in your glass, your shower, and your washing machine. A water filter at the tap masks the problem but doesn't fix it.
Low Water Pressure
Galvanized pipes narrow over time as mineral buildup and internal corrosion restrict flow. If your shower feels weak, your washing machine takes forever to fill, or pressure drops when someone runs a second faucet, your pipes are likely the bottleneck. This is common in older Evansville homes — the fix isn't a new showerhead, it's new pipe.
Frequent Leaks and Pinhole Leaks
One leak is an annoyance. Two or more in a year is a pattern. Pinhole leaks — tiny corrosive holes in aging pipe walls — signal that your plumbing is failing systemically. Patching individual leaks costs $150 to $400 each time, and you'll keep patching until the whole system gives out. Eventually, you're paying more to chase leaks than a repipe would cost.
PEX vs Copper: Which Material Is Right for Your Repipe?
When you repipe a house in Evansville, you've got two realistic options: PEX (cross-linked polyethylene) or copper. Each has tradeoffs.
PEX Repiping
PEX is flexible tubing that runs through walls with minimal cutting. It resists corrosion and scale buildup, handles Vanderburgh County's hard water well, and doesn't conduct heat the way copper does. PEX repiping is typically 30 to 40 percent cheaper than copper because installation is faster and requires fewer fittings.
Copper Repiping
Copper has been the standard for decades. It's rigid, durable, and has a proven 50-plus-year lifespan. It's also more expensive in both material and labor. Copper is worth considering in historic homes where code requirements favor metal, or if you plan to stay long-term and want maximum resale value.
What Does a Whole House Repipe Cost in Evansville?
Pricing for a whole house repipe in the Evansville area depends on your home's size, the number of fixtures, wall access, and the material you choose. In 2026, typical ranges are:
- PEX repiping: $4,000 to $8,000 for a 1,500 to 2,500 sq ft home
- Copper repiping: $8,000 to $15,000+ for the same size home
Homes with finished basements, multiple bathrooms, or limited wall access will trend higher. Older two-story homes in Riverside often cost more than ranch-style homes on the east side due to additional plumbing runs and harder-to-access walls.
What to Expect During the Process
A whole house repipe typically takes 2 to 5 days depending on home size and complexity. Here's the general timeline:
- Day 1 — Preparation: Plumbers assess your home, protect floors and furniture, and identify access points in walls and ceilings. Most cuts are kept small and strategic.
- Days 1-3 — Pipe Replacement: Old supply lines are removed or abandoned, and new PEX or copper is routed through walls, floors, and ceilings. Your water is off during work hours but restored each evening.
- Final Day — Inspection and Patching: A Vanderburgh County plumbing inspector verifies the work meets code. Wall and ceiling cuts are patched, and fixtures are reconnected and tested.
You can usually stay in your home during the repipe, though water access is limited during working hours. Many homeowners plan to be out during the day and return in the evening when water is restored.
Don't Wait for a Catastrophic Failure
The most expensive time to repipe a house is after a major leak floods your floors or a burst pipe damages walls and belongings. If you're seeing discolored water, dropping pressure, or recurring leaks in an older Evansville home, get an inspection now. A plumber with repiping experience can scope your lines with a camera and tell you exactly what condition they're in.
Whole house repipe costs are predictable. Water damage repairs are not.
