Cost to Repipe a House: 2026 Price Guide

I’ve repiped more than 600 houses in 20 years, and the first question is always the same: what is this going to cost me? The honest answer for 2026 is that a full PEX repipe runs $4,000 to $15,000 for most single-family homes, with a typical two-bathroom house landing right around $7,500. Copper pushes that number up by roughly 40 to 60 percent. Everything else in this guide — square footage, bathroom count, access, permits, drywall — explains where inside that range your house will fall, and why two quotes on the same street can differ by $4,000 without either plumber doing anything wrong.

If you are still deciding whether you need this job at all, read my breakdown of the signs your house needs repiping first. A repipe is major surgery. You want to be sure the diagnosis is right before you spend five figures. But if the signs are there — repeated pinhole leaks, rusty water, galvanized pipe — patching leak after leak is the most expensive way to own a house, and this guide will show you the math.

How much does it cost to repipe a house in 2026?

Here is the pricing I see on real invoices across typical residential work this year. These are full-service numbers: labor, pipe, fittings, valves, permit, and pressure testing included. Drywall patching and paint are usually extra, and I break those out separately below.

Repipe scope	PEX cost	Copper cost
1-bathroom house or condo	$4,000–$6,500	$6,000–$10,000
2-bathroom house	$6,000–$10,000	$9,000–$15,000
3-bathroom house	$9,000–$15,000+	$13,000–$22,000+
Average whole-house repipe	~$7,500	~$11,000–$12,000
Permit	$200–$800	$200–$800
Drywall patching (if added)	$300–$1,500 extra	$300–$1,500 extra

The per-square-foot view is useful when you are comparing quotes. Installed PEX runs $3.50 to $7 per square foot of living space. Installed copper runs $8 to $14 per square foot. Understand what that number hides, though: plumbing cost follows fixtures, not floor area. A 1,200 square foot house with three bathrooms costs more to repipe than a 2,000 square foot house with one and a half baths. Every toilet, tub, shower, sink, hose bib, and water heater connection is a run of pipe, a set of fittings, and labor hours. When a contractor quotes you purely by square footage over the phone without asking about bathrooms, that is a guess, not an estimate.

Access is the second big driver. A single-story ranch on a crawl space is the cheapest repipe there is — my crew can run new lines underneath and make short cuts up through the floor. A house on a slab costs more because everything must go through walls and the attic. A two-story house with finished ceilings on the first floor costs the most, because reaching the pipe means opening drywall in rooms people actually live in. Same pipe, same fixtures, very different labor.

What drives the cost of a repipe up or down?

Start with bathroom count, because that is how every experienced estimator actually prices the job. Each bathroom is a fixture group: toilet, lavatory, and tub or shower, plus the drain-side work is untouched but the supply side needs hot and cold runs to every point. One bathroom might be 8 to 10 supply connections. Three bathrooms plus a kitchen, laundry room, and water heater can be 30 or more. More connections means more pipe, more fittings, more holes, and more testing.

Second is the pipe material, covered in the next section. Third is your local labor market. A repipe in a high-cost metro can run 30 to 50 percent above the national ranges in my table, and rural areas with fewer licensed shops sometimes pay more too because there is no competition. Fourth is code requirements: some jurisdictions require a new main shut-off, backflow prevention, expansion tanks, or upsizing the water service line while the system is open. Those are legitimate add-ons, but a good contractor lists them as separate line items so you can see exactly what you are paying for.

Fifth, and most often underestimated, is restoration. The plumbing quote and the finished-wall quote are two different things. Opening drywall is fast. Patching it, taping, sanding, texturing, and painting it back to invisible is skilled finish work that takes days. Budget $300 to $1,500 extra for patching on a typical job, more if tile has to come out in a bathroom. Ask every bidder one direct question: does your price include patching, and to what finish level? Get the answer in writing.

Should you choose PEX or copper for your repipe?

I install both, and I will give you the same answer I give my own family. For most houses, PEX wins on cost, speed, and freeze resistance. PEX expands slightly when water freezes inside it, so a hard freeze that would split copper often leaves PEX unharmed. It is quiet — no water hammer bang at 2 a.m. — and because it comes in long flexible coils, a run from the manifold to a bathroom might have zero fittings hidden inside the wall. Every hidden fitting is a future leak point, so fewer fittings is a genuine reliability advantage, not just a labor saving.

Copper has real advantages too. It has a 70-plus-year track record, it is rigid and neat in exposed mechanical rooms, rodents do not chew it, and UV light does not degrade it. Some older inspectors and some local codes still favor it. Where I steer people to copper: exposed runs in a basement or utility room, houses with a known rodent problem in the walls, and short partial repipes where tying into existing copper is cleaner. Where I steer people away from copper: whole-house jobs on a budget, freeze-prone vacation homes, and houses with aggressive water chemistry that has already eaten one set of copper pipes from the inside. If your water pitted the last copper, it will pit the next copper.

Before you hire anyone for a job this size, read my guide on plumber vs handyman — a repipe is permitted, inspected work that belongs to a licensed plumber in every state I know of, full stop.

How long does a whole-house repipe take?

Plan on two to five days for the plumbing work. A one-bathroom, single-story house with good access can be done in two days. The average two-bath house takes three days: day one for running new lines, day two for tie-ins and fixture connections, day three for pressure testing, inspection, and turning the system fully live. Three-bathroom and two-story houses run four to five days, especially if the water service from the street is being replaced at the same time.

Your water will be off in stretches, not for the whole job. On most of my repipes, the house has water every night. There is typically one planned shutdown of four to eight hours when we cut over from the old system to the new one. Fill the bathtub before that day — you will want water to flush toilets manually — and plan showers around it. If anyone in the house depends on medical equipment that uses water, tell your plumber before scheduling, not the morning of the shutdown.

Do you need a permit to repipe a house?

In almost every jurisdiction, yes. A whole-house repipe is a permitted job, and the permit typically costs $200 to $800 depending on your city and the scope. The permit buys you an inspection, and on a job where 95 percent of the work gets buried inside closed walls, that independent inspection is genuinely valuable. The inspector pressure-tests the system, checks pipe sizing, support spacing, and protection plates where pipes pass through studs.

Treat an unpermitted repipe quote as a red flag. It will be cheaper — the contractor skips the fee and the inspection wait — but you inherit the risk. Unpermitted plumbing surfaces at resale when a buyer’s inspector finds shiny new pipe and asks for paperwork you do not have. It also matters for insurance: a water damage claim on a system that was installed without a required permit gives the insurer an argument you do not want to have. Every quote I write includes the permit as its own line. Ask for the same.

How can you keep your repipe cost down without cutting corners?

The legitimate savings are in access and timing, not materials. If your basement ceiling or crawl space is coming out for another project anyway, schedule the repipe then — open access can cut labor by 20 percent or more. Clearing furniture and storage away from walls where we will cut saves billable hours; my crew moves furniture carefully, but we are expensive furniture movers. Being flexible on scheduling helps too: a shop will often sharpen its price for a job that fills a gap week rather than one that must start Monday.

Get three written quotes, and make each bidder quote the same scope: same material, same fixture count, permit included or not, patching included or not. The lowest number on mismatched scopes is meaningless. I have won jobs where I was $1,200 higher because my quote included patching and permits and the cheaper one included neither — the homeowner did the honest math and realized the cheap quote was actually the expensive one.

What happens if you put off a repipe your house needs?

The costs compound. One pinhole leak repair runs $250 to $600 with access and patching. Homeowners who call me after the fourth or fifth leak have often spent $2,000 to $3,000 on spot repairs — a third of a repipe — and still own a failing system. Meanwhile every slow hidden leak is feeding mold, rotting subfloor, and swelling your water bill. The other real risk is the big failure: a burst supply line can put thousands of gallons into a house in a single day and turn a planned $7,500 repipe into a $25,000 insurance event with remediation, flooring, and a family in a hotel.

That is why I tell people to treat the decision as a timing question, not an if question, once the pipe has reached the end of its life. Galvanized pipe installed in the 1960s is not going to have a good decade. Polybutylene is not going to heal. Plan the repipe for a season that suits you, get the quotes in writing, line up the patching, and do it once, on your schedule, instead of at 11 p.m. on a holiday weekend at emergency rates.

When should you call a pro about repiping?

Call a licensed plumber for a repipe assessment when you have had two leaks in a year, when your water runs rusty after sitting, when pressure has dropped across the whole house, or when you know your pipe is galvanized or polybutylene and you are planning to stay in the home. A good assessment visit costs little or nothing, takes an hour, and should end with three things: identification of your pipe material and its condition, a written scope with a fixed price, and an honest answer on timing — including “you can wait two years” if that is the truth. If a contractor will not put the scope and price in writing, keep calling. I am Dan Reeves, licensed master plumber. I have opened enough walls to know exactly what failing pipe looks like, and the homeowners who do best on this job are the ones who planned it instead of having it planned for them by a burst pipe.
