How much does it cost to fix a pinhole copper leak in Phoenix?

An accessible single-leak pipe or fitting repair starts at $495. Access drives the price more than the pipe does, so a leak behind tile or up in a ceiling costs more than one under a sink — we confirm the number before we start. If the leak turns out to be under the slab, a slab leak spot repair on a pressurized line starts at $895. If we need to make the home safe first, an emergency shutoff and make safe starts at $295.

Is the leak located and quoted before you start the repair?

Always. We locate the leak first, then give you a firm repair quote before any work begins. You'll never get an open-ended bill. The locate is priced from our pricebook — a full system pressure test and isolation starts at $345, a thermal imaging leak scan starts at $395, and a static line test on a sewer line starts at $395. So is the repair: an accessible pipe leak repair on a single leak starts at $495, a meter box and yard line repair on a single break starts at $895, and a full water service line replacement starts at $3,495. If the leak is under your slab, that's a different process — see our slab leak pricing page.

What Does Leak Detection & Repair Cost in Phoenix?

Q: How much does leak detection cost in Phoenix?

A standard service call and diagnostic starts at $89, and a virtual video diagnostic starts at $49. A full system pressure test and isolation starts at $345, and a thermal imaging leak scan — locating a hidden leak without tearing into your home — starts at $395. After-hours or emergency diagnostics start at $189. We locate the leak and quote the repair upfront before any work begins, because every leak is different.

Q: How do you find a hidden leak without tearing up my house?

We start non-invasively — a full system pressure test and isolation, starting at $345, tells us whether the leak is on the supply side and which section is losing water. A thermal imaging leak scan, starting at $395, narrows it down further before we open anything. That means we open one accessible section instead of guessing across a wall, and we'd rather spend the time locating it precisely than tear out drywall hoping to find it.

Electronic Detection · Pinhole & Supply-Line Repair · Main Service Lines · Updated May 2026

A leak you can see is a leak you can quote. The hard part with hidden leaks is finding them — and the honest truth is that no two leaks cost the same. A pinhole in an exposed copper line under the sink is a different job than a supply line buried in a ceiling or a service line running across your yard.

So here's how we do it: we locate the leak first, then hand you a firm repair price before any work starts. The numbers below are the real starting prices from our pricebook — for the locate, the response work, and the repair itself — presented as "starts at," not a flat rate, because the right number depends on where the leak is and how we have to get to it. Access, drywall repair, and surface restoration are separate line items, and they're on your quote before we start. Pick the situation that sounds like yours.

Don't Know Where It Is — Find It

Leak Detection

From $345

A pressure test and a thermal imaging scan narrow a hidden leak down before we open a single wall. The right first step when you've got high bills or wet spots and no source.

See detection breakdown ↓

Found It — Make It Safe, Then Fix It

Response & Repair

From $195

Shutting the water down, documenting the damage, coordinating mitigation — then the repair itself, quoted upfront once we've located it and can see the access.

See response options ↓

Yard, Meter, or Sewer Line

Buried Line Testing & Repair

From $395

A static line test on the sewer starts at $395. A single break at the meter box or yard line starts at $895, and a full water service line replacement at $3,495. Locating it precisely saves the most digging.

Leak Detection

Finding the Leak Before We Open Anything

A leak that's behind drywall, under a cabinet, or in a ceiling can run for weeks before you see a stain. We find it without guessing. A pressure test isolates whether the leak is on the supply side; a thermal imaging scan then narrows down where the water actually is. That means we open one accessible section instead of tearing into a wall hoping to get lucky.

Virtual Video Diagnostic

A video call where you walk us through what you're seeing. Cheapest way to find out whether you need a tech out, and sometimes we can tell you it's nothing over the phone.

Starting at

From $49

Standard Service Call & Diagnostic

A tech on site to look at it in person. After-hours and emergency diagnostics start at $189 — if it can safely wait for regular hours, we'll tell you so rather than sell you the emergency call.

Starting at

From $89

Full System Pressure Test & Isolation

We pressurize and isolate the system to confirm whether you actually have a leak and which section is losing water. Frequently the first thing we do before quoting anything else.

Starting at

From $345

Thermal Imaging Leak Scan

Scanning walls, ceilings, and floors with a thermal camera to find where the water actually is. This is the locate — the repair is quoted separately, upfront, once we know what reaching it involves.

Starting at

From $395

Why We Locate Before We Cut

Tearing out drywall to "go look" is how you end up with three holes and a bigger repair bill. Spending the time to pinpoint the leak first usually means we open one spot, fix it, and patch one patch. We'd rather lose the bid than do it wrong — and doing it wrong starts with guessing where the water is coming from. If the leak turns out to be under your concrete slab, that's a separate process — see our slab leak detection & repair pricing →

Response & Repair

Once We Find It — Access Drives the Price

Once the leak is located, the repair cost comes down to one thing more than any other: how hard it is to get to. A pinhole in an exposed line under a sink is quick. The same pinhole behind tile or up in a ceiling means opening, repairing, and patching — and the patch is part of the job. An accessible single-leak repair starts at $495; harder access moves it up, and we confirm your number before we start rather than after. The detection and response work around it is priced below.

Click each option to see what the job involves and when it applies.

Make Safe

Emergency Shutoff & Make Safe

Starting at

From $295

Water actively running where it shouldn't be. We get it shut off and isolated, cap or valve off the failed section, and get the rest of the house back in service so you're not living without water while the repair gets scheduled.

Water shut off and the failed section isolated
Capped or valved off so the rest of the house stays usable
System pressure-checked before we leave it overnight
Best for: an active leak that can't wait for the full repair

When this appliesThe priority is stopping the water, not finishing the repair the same hour. Making it safe first means the repair gets done properly rather than in a panic.

Common

Pipe & Fitting Leak Repair Phoenix Classic

Starting at

From $495

The tiny corrosion leaks that Phoenix's hard water and high pressure produce in copper lines, plus the failed fittings and split sections that come with them. We cut out the bad section and replace it. An accessible single-leak repair starts at $495. Where the pipe is behind finished surfaces or more of the line is compromised, the number moves — and we quote it before we start.

Accessible single-leak repair starts at $495
Remove and replace the failed pipe or fitting
Inspect the surrounding line for additional corrosion
Pressure-tested after the repair to confirm it's sealed
Firm number given to you before we start — always

The honest caveatIf we're finding multiple pinholes across the same copper system, patching one at a time can become a money pit. We'll tell you straight if you're better served by repiping a run rather than chasing leaks — and we'll never push that if a simple repair will hold.

Document

Moisture Mapping & Documentation

Starting at

From $345

Mapping how far the water actually traveled through drywall, framing, and flooring, with meter readings and photos written up. This is the piece that matters when an insurance claim is involved — a documented map of the wet area beats an argument about it later.

Moisture meter readings across the affected area
Photos and a written record of what's wet and how far it spread
Gives you something concrete to hand your insurer
Best for: leaks that ran a while before anyone noticed

Why this is worth doingThe wet area is almost always bigger than the stain you can see. Mapping it means the drying and repair scope match reality instead of the visible spot.

Mitigation

Water Damage Mitigation Coordination

Starting at

From $195

When a leak has soaked drywall, framing, or flooring, drying it out properly is a restoration job, not a plumbing one. We coordinate the handoff — getting a mitigation crew in, sharing what we found and where the water went, and making sure nothing falls between the two trades.

Mitigation crew scheduled and briefed on our findings
Our leak documentation handed over so nothing gets re-diagnosed
Plumbing repair sequenced around the drying work
Best for: leaks that soaked materials, not just a wet spot

Worth catching earlyWet framing that never gets dried out becomes a much larger problem than the leak that caused it. If the water sat, coordinating mitigation now is cheaper than the repair later.

Located First, Quoted Upfront — Every Time

Every leak is different, so we don't pretend to flat-rate them sight unseen. We locate the leak, look at how we have to reach it, and give you a firm number before we touch anything. If a small accessible repair will hold, that's what we quote — we don't inflate it into a behind-wall job. We'd rather lose the bid than do it wrong.

Leak out in the yard? See main service line ↓

Main Water Service Line

The Yard Line — Meter to House

The main water service line is the buried pipe that carries water from your meter to the house. When it leaks, you'll often see it as a soggy patch in the yard, an unexplained jump in your water bill, or water pooling near the meter. This is the big-ticket leak repair — and the one where pinpointing the leak before digging saves the most, because every foot of trench costs money.

Static Line Test — Sewer

Filling and holding the buried sewer line to see whether it actually holds water. The standard way to prove a buried line is leaking — or prove it isn't — before anyone breaks ground on a yard.

Starting at

From $395

Full System Pressure Test & Isolation

For the pressurized side — the meter-to-house water line. We isolate sections to confirm the loss is out in the yard rather than inside the house, so the digging happens where the problem is.

Starting at

From $345

Meter Box & Yard Line Repair — Single Break

Repair of a single leak between the meter and the house, with excavation up to 3 feet deep in accessible native soil, including the pipe repair and backfill. Additional breaks on the same line are quoted before we proceed. Surface removal and restoration are separate line items.

Starting at

From $895

Water Service Line Replacement — Good, Better, Best

When the line is too far gone to patch, we replace it. Good starts at $3,495 for an open-trench replacement up to 40 feet at a depth up to 3 feet with permit and inspection; Better at $4,995 up to 60 feet with an upsized line, new main shutoff and surface restoration to grade; Best at $6,995 up to 80 feet with a pressure regulator, concrete and landscape restoration, and a lifetime workmanship warranty. Beyond the included length it's $65 per additional linear foot.

Starting at

From $3,495

Why the Starting Prices Move on This One

A buried line repair depends almost entirely on what's between the leak and the surface. Depth, soil, length of the run, and what's on top — grass, concrete, pavers, a driveway — all move the number, and they move it a long way. A single break repaired at 3 feet in native soil starts at $895; a full replacement of a long, deep, or paved-over line starts at $3,495 and climbs with length and restoration. Deeper digging, rock, or caliche is charged from our excavation adders, and length past the package is $65 per additional linear foot. What we can price flat upfront is the testing that tells us which one you're looking at. We locate the leak, assess access, and give you a real number before any digging starts. Note: if the leak is under your home's concrete slab rather than out in the yard, that's a different job — see slab leak pricing →

Why Phoenix Homes Leak

Hard Water + High Pressure = Pinhole Leaks

Phoenix is hard on plumbing for two reasons that stack on top of each other. The water here is hard and mineral-heavy, which is corrosive to copper over the years. And municipal pressure across much of the Valley runs 80–120 PSI — well above the 60–70 PSI a residential system is built to live with comfortably.

High pressure forcing hard water through aging copper is exactly the recipe for pinhole leaks and premature pipe failures. It's why we see so many of them out here, and why a pressure regulator is sometimes the smartest money you can spend to slow the next leak down. We'll tell you if yours is running hot.

Leak Detection & Repair — FAQ

How much does leak detection cost in Phoenix?

A standard service call and diagnostic starts at $89, and a virtual video diagnostic starts at $49. A full system pressure test and isolation starts at $345, and a thermal imaging leak scan — locating a hidden leak without tearing into your home — starts at $395.

How do you find a hidden leak without tearing up my house?

We start non-invasively. A full system pressure test and isolation, starting at $345, tells us whether the leak is on the supply side and which section is losing water. A thermal imaging leak scan, starting at $395, narrows down where the water actually is before we open anything. That means we open one accessible section instead of guessing across a wall — we'd rather spend the time locating it precisely than tear out drywall hoping to find it.

How much to fix a pinhole copper leak?

An accessible pipe leak repair on a single copper, PEX, or galvanized supply line leak — in an attic, wall cavity, or crawlspace, pressure test included — starts at $495. Drywall access and repair are separate line items, and access moves the total more than the pipe does, so we confirm your number before we start. If the leak turns out to be under the slab, a slab leak spot repair on a pressurized line starts at $895. If the water has to be stopped first, an emergency shutoff and make safe starts at $295. And if we're finding pinholes all over the same aging copper, we'll tell you honestly whether repiping a run beats chasing leaks.

Why do Phoenix homes get pinhole leaks?

Two reasons specific to the Valley. First, Phoenix has hard, mineral-heavy water that's aggressive on copper over time. Second, municipal water pressure here often runs 80–120 PSI — well above the 60–70 PSI a home plumbing system is happiest at. High pressure plus hard water accelerates corrosion and produces the pinhole leaks and premature pipe failures we see constantly in older copper systems. A pressure regulator is often the cheapest fix to slow it down.

How much does a buried yard line leak cost to fix?

The testing is priced upfront: a static line test on a sewer line starts at $395, and a full system pressure test and isolation on the pressurized water line starts at $345. For the repair itself, a meter box and yard line repair on a single break — excavation up to 3 feet in accessible native soil, pipe repair and backfill — starts at $895. When the line is too far gone to patch, a full water service line replacement starts at $3,495 up to 40 feet, $4,995 up to 60 feet, and $6,995 up to 80 feet with restoration, plus $65 per additional linear foot. Depth, soil, and what's on top of the line — grass, concrete, or a driveway — move it from there, and surface restoration is a separate line item. We locate the leak first so we dig where the problem is rather than trenching the whole line. If the leak is under your home's slab rather than in the yard, see our slab leak pricing →
