Stop Guessing Where the Water Is Going
Valley homes are tough on plumbing. The water here is some of the hardest in the country, and it scours pipe from the inside year after year. Summer heat and monsoon moisture keep the soil under your slab moving. Somewhere in all that, a copper line develops a pinhole, and water starts going where it shouldn’t. Quietly.
PlumbSmart finds those leaks across Mesa, Phoenix, and the East Valley, in homes and businesses alike. Slab leaks, wall leaks, underground yard lines, fixtures, sewer lines. We use infrared thermal imaging, acoustic listening equipment, and pressure testing to pinpoint the source without tearing your house apart looking for it.

What Our Leak Detection and Testing Covers
If water is escaping somewhere it shouldn’t, we have a tool that can find it. Here’s what we test for across the Valley, in homes and businesses alike.
Slab Leak Detection
Warm tile, damp carpet, or a bill that won’t quit usually points under the slab. Slab leak repair starts with finding it exactly.
Pressure Testing
We isolate your lines and watch the gauge. A pressure drop tells us which section is losing water before we open anything.
Infrared Thermal Imaging
Moisture changes temperature. Our thermal cameras spot it behind drywall and under floors without cutting a single hole.
Acoustic Leak Detection
Escaping water makes a sound. Sensitive listening gear picks it up through concrete and soil, so we dig in the right spot the first time.
Sewer Camera Inspection
A video camera shows us roots, cracks, and buildup inside the line. Camera inspections are free right now, normally $250.
Underground Yard Line Leaks
Soggy grass or a hissing meter? We trace yard water line leaks without trenching the whole lawn.
Shower and Fixture Leaks
Drips behind the valve and trim that stain the ceiling below. We find them before all the tile has to come off.
Water Heater and Softener Leaks
Tanks, fittings, and softener heads fail quietly in a garage corner. We catch it before the floor does.
High Water Bill Investigations
When the bill doubles and nothing looks wrong, we test the whole system, meter to fixtures, and find where the water went.
How Our Leak Detection Works
Four steps, no surprises. You know the price before any repair starts.
Same-Day Visit
Tell us what you’re seeing. A licensed plumber comes out, often the same day, with no trip charge.
Pinpoint the Leak
Infrared, acoustic, and pressure testing narrow it down to one exact spot, marked and explained.
Upfront Flat Quote
You get one clear, flat price for the fix to approve before we start. The bill matches the quote.
Repair, Test, Warranty
We make the repair, retest the line to prove it holds, and back the work with our lifetime warranty.
Watch a Sewer Camera Find the Problem
This is real PlumbSmart camera footage from a Valley sewer line. Tree roots found a small opening, moved in, and built a blockage that was backing up the whole house. Three minutes of video, and there’s no arguing about what the problem is or where it sits.
That same inspection, normally $250, is free right now. If you’ve never seen inside your sewer line, this is the time.

Every day it runs, the damage and the bill grow. Most detection visits happen same day.
What Does Leak Detection Cost in Mesa?
Honest answer: it depends on how well the leak is hiding. A dripping fixture takes minutes to confirm, while a slab leak under the master bedroom takes real equipment and real skill to isolate. What never changes is how we price it. There’s no charge just to come out, and once we know what we’re dealing with, you get one flat quote to approve before any repair begins. No meter running, no surprise at the end.
Find It First, Then Fix It Right
Detection is half the job. Once we know exactly where the water is going, the same technician can quote the fix on the spot, from a pinhole repair to a full reroute. Our leak repair team handles it all, and you approve one flat price before anything starts.
And when a home’s pipes are failing in more than one place, we’ll tell you straight. Sometimes a whole house repipe beats chasing leak after leak through fifty-year-old copper. We’ll show you the numbers both ways and let you decide. You get the honest version, not the expensive one.
Why Arizona Homes Hide Leaks So Well
There’s no basement here to catch a drip. Water lines run under the slab and inside the walls, so a leak can run for months with nothing to show for it but a bigger bill. The first clue is usually indirect: warm tile, a musty closet, a water meter that won’t sit still when every faucet is off.
By the time water shows at the surface, it’s been working on your foundation for a while. That’s why we treat the small signs seriously, and why an early detection visit is some of the cheapest plumbing money you’ll ever spend.

Leak Detection Questions, Answered
How Much Does Water Leak Detection Cost in Mesa?
It depends on how deep the leak is hiding. A fixture leak we can see right away takes less time to pin down than a slab leak under the living room floor. What stays the same is how we price it: no trip charge to come out, and a flat, upfront quote you approve before any repair starts. Many customers tell us our bids come in well below the big-name companies. Call 480-654-8865 and we’ll take a look.
How Do You Find a Leak Without Tearing Up My House?
With the right tools instead of a sledgehammer. Our technicians use infrared thermal imaging to spot temperature changes behind walls and under floors, acoustic listening equipment to hear water escaping inside pipes, and pressure testing to confirm which line is losing water. That means we can mark the leak’s location precisely, so any opening of walls or floors happens in one small spot instead of five guesses.
What Are the Signs of a Hidden Water Leak?
A water bill that jumps without explanation, the sound of running water when everything is off, warm spots on a tile floor, a musty smell, soft or stained drywall, low water pressure, or a water meter that keeps spinning with every fixture closed. In Arizona, where most homes sit on a concrete slab, you rarely see the leak itself. You see the side effects first, and the earlier you act on them the smaller the repair.
Why Are Slab Leaks So Common in Arizona?
Most Valley homes are built on concrete slabs with the water lines running beneath them. Our water is some of the hardest in the country, and over the years it wears copper pipe from the inside while the soil under the slab expands and contracts through summer heat and monsoon moisture. Add hot water lines that flex with every use, and pinhole leaks become common as homes age. If we confirm one, our slab leak repair team handles it start to finish.
What Is the Free Sewer Camera Inspection?
Exactly what it sounds like. We run a video camera through your sewer line and show you what’s down there: tree roots, cracks, bellies in the line, or buildup that’s heading toward a backup. It’s a $250 inspection that we’re currently offering free, and there’s no obligation attached to it. Just mention the offer when you book.
What Is Pressure Testing and When Do I Need It?
Pressure testing isolates a section of plumbing and watches whether it holds steady. If the pressure drops, water is escaping somewhere in that section. It’s how we confirm a suspected slab leak, check a yard line, or verify a home’s plumbing before a sale or remodel. It’s also the test that proves a repair worked before we call the job done.
Do You Repair the Leak After You Find It?
Yes, and that’s the point of doing both under one roof. The technician who locates your leak can quote the repair on the spot, from a simple fixture fix to a slab leak reroute or a yard line replacement. You get one flat price, one company to deal with, and a lifetime warranty on the work.
How Long Does Leak Detection Take?
Most leak detection visits wrap up within a couple of hours, including testing and marking the location. Tricky leaks, like a slab leak under a large home or an underground yard line, can take longer to isolate. We’ll give you an honest read on timing when we see the situation, and same-day appointments are available most days.
Will Insurance Cover My Water Leak?
Every policy is different, so we won’t pretend to speak for yours. What we can do is document everything: a detailed invoice, photos of what we found, and before and after photos of the repair. Customers tell us that paperwork makes the insurance conversation a lot easier. Check with your carrier about coverage for sudden water damage versus the plumbing repair itself, since policies often treat those differently.
Is Your Work Guaranteed?
Yes. PlumbSmart backs its repairs with a lifetime warranty. If something we fixed does not hold up, we come back and make it right. We’ve held an A+ rating with the BBB since 2012 and zero complaints with the Arizona Registrar of Contractors, and we intend to keep both.
What Areas Do You Serve?
We cover Mesa, Phoenix, Tempe, Gilbert, Chandler, Scottsdale, Queen Creek, Apache Junction, Fountain Hills, and the surrounding Valley communities. Not sure if you’re in range? Call 480-654-8865 in Mesa or 623-250-2238 in Phoenix and we’ll let you know.
What Should I Do if Water Is Leaking Right Now?
Shut off the water at the main valve, usually near the hose bib at the front of the house or at the meter box by the street. Then call us. We run a 24-hour emergency line at 602-256-9181, because a burst line at 2 a.m. can’t wait for business hours. Shutting off the main stops the damage while a tech heads your way.
