Repiping a house typically runs from several thousand dollars into the tens of thousands, driven mainly by the size of the home, the pipe material used, and how much drywall, flooring or ceiling needs to be opened up and repaired afterward. A single-story home with crawl-space access costs far less than a multi-story home built on a slab.
Why a Repipe Costs So Much More Than a Single Repair
A normal plumbing repair fixes one point of failure. A repipe replaces the entire supply system, which means every wall or floor the old pipes run through has to be opened up, the new lines run, and then everything patched and finished again. Most of the total bill is not the pipe itself, it is the labor to access it and the repair work afterward.
How we actually vet the plumbers on our lists
For a job this disruptive, we weight review consistency more heavily than the overall star rating when we research plumbers for our Top 5 lists. A plumber with years of steady, positive reviews for larger jobs, not just quick callouts, is a stronger signal than a high average built mostly on small repairs. We also check whether a business is upfront about permits and inspections for whole-home work, since skipping that step is one of the clearest shortcuts a bad contractor takes.
The Biggest Cost Driver: Pipe Material
PEX is generally the least expensive option and flexible enough to snake through existing walls with less demolition. Copper costs more in materials and labor but has a long track record and is often preferred for exposed runs. CPVC sits somewhere between the two. The right choice depends on your local code, your water pressure, and what the rest of your home's plumbing already uses, so this is worth discussing directly rather than assuming cheaper is automatically the better call.
How Much of the House Actually Needs to Come Apart
A home with an accessible crawl space or basement lets a plumber run most new lines without touching finished walls. A home on a slab, or one where pipes run through multiple stories, usually needs more drywall opened up, which is where costs climb fastest. Ask any quote to specify exactly how much wall, ceiling or flooring will be cut into, and whether patching and repainting is included in the price or billed separately.
Signs Your Home Might Actually Need a Repipe
- Recurring pinhole leaks in different spots. One leak is a repair, several over time across the house points to failing pipe.
- Discolored water, especially after periods of not running a tap. Often a sign of corroding galvanized pipe.
- Persistently low water pressure throughout the home. Can mean narrowing, corroded pipe interiors rather than a single blockage.
- Your home still has original galvanized steel pipe. Most galvanized systems are well past their realistic service life.
Questions Worth Asking Before You Agree to a Repipe
Ask how many days the job will take and whether you will have any running water during that time, whether the quote is a fixed price or subject to change once walls are opened, and who handles the drywall patching and paint matching afterward. A plumber who has done this work many times will have clear, specific answers to all three.
Older homes with galvanized or lead-containing supply lines are also a water-quality issue, not just a plumbing one. The EPA's guidance on drinking water is worth a look if you are not sure what your home's original pipe material actually is.
This is exactly the kind of job worth getting more than one opinion on. Our Top 5 plumbers list is independently researched town by town, from Prosper, TX to Midtown Manhattan to Atlanta, GA, so you are starting from a shortlist that has already been checked for a genuine local track record.
