Repiping a House Cost (2026)

By HomeCost Guide · Updated October 2026 · national average for a full repipe of a typical 2-bath home, per HomeGuide and Angi

Repiping a house costs $4,000 to $15,000 for most American homes, with a national average of about $10,000 according to data published by HomeGuide and Angi. That wide spread exists because a repipe is really two jobs bundled together: replacing every water supply line in the house, and then repairing the drywall, plaster, and flooring that gets opened up to reach them. A small one-bath ranch repiped with PEX can land near the bottom of the range, while a large two-story home repiped in copper — with extensive wall patching — can push past $20,000. Material choice is the single biggest lever on price. PEX tubing is the budget option and the most common choice today; copper costs roughly twice as much installed but carries the longest track record; CPVC sits in between. Most plumbers also quote by fixture count — expect $450 to $800 per fixture for a full repipe — which makes it easy to sanity-check any bid against your home's size. This guide breaks down what each material costs installed, the hidden line items (permits, drywall, water main upgrades), and the questions that separate a fair quote from an inflated one.

1. Repiping a House Cost (2026) cost breakdown

Published averages cluster around $10,000 nationally, but working plumbers consistently report PEX repipes coming in 30–50% below copper for the same house. Quotes above $20,000 usually involve large homes, difficult access (slab foundations, plaster walls), or extensive finish repair — ask for those line items broken out separately before accepting the bid.

Where the money goes: labor vs materials vs fees

• Labor$3,000–$8,000The crew's time is the largest line item — typically 2 to 5 days for a 2-bath home. Expect the high end in expensive metros and for homes with plaster walls, finished basements, or slab foundations that slow access.
• Pipe and fittings$1,000–$5,000Material swings with your choice: PEX tubing and fittings for a typical home run $1,000–$2,000, while copper pipe and soldered fittings can reach $4,000–$5,000 before a single wall is opened.
• Permits and inspections$150–$500Most cities require a plumbing permit plus a pressure-test inspection for a whole-house repipe. Your plumber usually pulls the permit — confirm it's included in writing rather than billed later as an extra.
• Drywall, texture and paint$1,000–$4,000The restoration tail is the most underestimated cost. Plumbers cut access holes in walls and ceilings; many do basic patching but not texture matching or repainting. Get a clear answer on who finishes the walls.

2. Signs your house needs repiping

Signs your house needs repiping

• Rusty, brown, or yellow water from taps — especially hot-water taps — signals corroding galvanized or iron pipe.
• Water pressure that has faded over the years, caused by mineral scale narrowing old pipes from the inside.
• Two or more pinhole leaks within 12 months; every repair is a warning the system is failing house-wide.
• Visible corrosion, flaking, or dimpling on exposed pipe in the basement, crawlspace, or utility room.
• Galvanized steel supply pipes 40–50+ years old — their typical service life is about 50 years, and they're on borrowed time past that.
• A sudden jump in the water bill with no visible leak, which can mean a supply line leaking inside a wall or under the slab.

3. How a whole-house repipe works

How a whole-house repipe works

1. Inspection and fixture count. The plumber walks the house, counts fixtures (sinks, toilets, tubs, hose bibs, water heater), checks access routes, and identifies the existing pipe material. This visit produces the per-fixture math behind your quote.
2. Material selection and written quote. You choose PEX, CPVC, or copper. A proper quote lists the material, fixture count, permit fees, and exactly what wall repair is included — not a single unexplained lump sum.
3. Permit and scheduling. The plumber pulls the municipal permit. Most repipes run 2–5 consecutive days; water is shut off during work hours but usually restored each evening.
4. Installation. Crews run new supply lines through attics, crawlspaces, or alongside old pipes, connecting each fixture. Old pipes are normally abandoned in place rather than torn out, which saves demolition cost.
5. Pressure test and inspection. The new system is pressurized and checked for leaks, then the city inspector signs off. Never skip this — it validates both the workmanship and your warranty.
6. Patching and restoration. Access holes get patched with drywall. Confirm beforehand whether texture matching and repainting are included or left to you or a separate drywall contractor.

4. What affects the cost

Number of fixtures

Plumbers price repipes by fixture count more than square footage, because every sink, toilet, tub, shower, hose bib, dishwasher, and washing-machine hookup is a separate pipe run with its own connections. A 1-bath ranch with 6 fixtures is a fundamentally smaller job than a 3.5-bath house with 14 fixtures — the $450–$800 per-fixture rule of thumb captures this directly. Count your own fixtures before getting quotes; it takes five minutes and instantly tells you whether a bid sits in the right neighborhood or has been padded.

Pipe material: PEX vs copper vs CPVC

Material is the biggest single cost lever. PEX is cheapest installed — flexible tubing snakes through walls with fewer fittings and less labor — and it's now the default in most markets. Copper costs roughly double installed: the pipe itself is pricier and every joint is soldered by hand, which is slow, skilled work. CPVC lands between the two. Copper's advantage is a 70-plus-year track record and no plastic-taste concerns; PEX's is cost, speed, and freeze resistance. Price both materials if you're torn — the gap for one house is often $4,000–$6,000.

Home size and number of stories

A two-story home costs more than a ranch of equal square footage because vertical runs, upstairs bathrooms, and longer pipe paths add both material and labor. Multi-story repipes also mean more ceiling penetrations between floors and trickier fishing of lines through finished walls. Plumbers commonly add 20–40% for a second story versus a single-level home with a similar fixture count, so don't compare quotes across different house shapes without adjusting.

Access: basement, crawlspace, or slab

Homes with a basement or tall crawlspace give plumbers open access to run new lines underneath — fast and comparatively cheap. Slab-on-grade homes are the expensive case: supply lines often run through or under the concrete, so crews must cut the slab, tunnel beneath it, or reroute lines overhead through the attic. Attic reroutes are standard practice in warm climates and add labor but avoid concrete work; expect slab homes to price 25–50% higher than the same house on a crawlspace.

Wall and ceiling finish repair

The plumbing is only half the invoice. Every access hole needs drywall, tape, texture matching, and paint — and plaster walls or custom textures like knockdown or orange peel cost far more to restore invisibly than flat drywall. Some plumbers include basic patching; few include texture and paint. Ask for the finish scope in writing, and budget $1,000–$4,000 for restoration if it's excluded — or get a separate drywall bid so the number is real instead of a guess.

Local labor rates

Plumbing labor varies enormously by metro. In high-cost coastal markets a repipe crew bills $150–$250 per hour; in lower-cost regions the same crew might run $75–$125. Because labor is the majority of a repipe's cost, geography alone can swing the total $3,000–$5,000 for an identical house. Always compare quotes from local plumbers — national averages are a starting point, not a price tag, and a 'cheap' national figure means nothing in San Francisco or Boston.

Condition of the old system

Working around the old pipes adds cost when they're badly corroded, encased in concrete, or made of materials like polybutylene that insurers dislike. Most repipes abandon old lines in place, which is cheap — but if local code or your insurer requires removal, or if corroded galvanized sections must be cut out to make clean connections, add labor hours. A thorough pre-quote inspection should flag this; a plumber who never looks in the crawlspace before quoting is guessing.

Water main and shutoff upgrades

Many older homes still have a galvanized or undersized water main, a seized main shutoff valve, or no pressure regulator. Plumbers often recommend replacing the service line to the meter and adding a regulator and new shutoffs while the system is open — sensible work, but it's a $1,000–$3,000 add-on that may not sit in the base quote. Ask whether the bid covers the house only or includes the service line, and make it a deliberate decision rather than a day-of surprise.

Permits, inspections, and code upgrades

A repipe permit typically costs $150–$500, but the inspection can trigger code upgrades: water hammer arrestors, an expansion tank on the water heater, or updated shutoff valves at each fixture. These are small-ticket items individually ($50–$200 each) that accumulate across a whole house. Reputable plumbers disclose likely upgrades in the quote; vague bids that 'exclude code-required items' are where surprise change orders come from — get the exclusions listed, not just the inclusions.

Planned project vs emergency

Emergency repipes — after a burst pipe floods a home — cost more than planned projects because you're paying for priority scheduling and often water-damage mitigation alongside the plumbing. A planned repipe booked 2–4 weeks out lets you collect three quotes and schedule around your life. If your pipes are aging but intact, the cheapest repipe is the one you plan before it becomes urgent; every year of delay also risks the kind of leak that turns a $10,000 repipe into a $25,000 plumbing-plus-restoration bill.

5. Saving money & hiring right

Questions to ask your contractor

• Are you quoting PEX, CPVC, or copper — and can you price all three so I can compare?
• How many fixtures did you count, and what per-fixture price sits behind this quote?
• Is the permit fee included, and will the work be inspected and pressure-tested?
• Exactly what wall, ceiling, and floor repair is included — patching only, or texture and paint too?
• Will you abandon the old pipes in place or remove them, and why?
• What warranty do you offer on labor and materials, and is it in writing?

6. How costs vary by state

Repipe costs track local plumbing labor rates more than material prices, so high-cost coastal metros run 20–40% above the national average while the Southeast and parts of the Midwest run 15–30% below. Slab foundations — standard across Texas, Florida, and Arizona — add their own premium regardless of labor rates.
