Leak Detection and Repair
Leak Detection and Repair Phoenix AZ You Can Count On
When water shows up where it shouldn't, our leak detection and repair Phoenix AZ team tracks it down fast using acoustic listening gear, thermal imaging, and pressure testing.

Service overview
Leak Detection and Repair Phoenix AZ Done Right
Leak detection and repair Phoenix AZ is the process of locating water escaping from your plumbing system, confirming the exact failure point, and fixing it without tearing your home apart. We start with a pressure gauge on the main line, then use acoustic listening equipment and thermal imaging to isolate the leak. Once we know where it is, we open the smallest possible access point, repair the pipe, and pressure-test the line before we close anything up.
Phoenix homes need this service more than most. Our water runs hard and hot, and the ground shifts with the clay soil. Copper pipe from the 1970s and 1980s develops pinhole leaks, and slab leaks show up as hot spots on the floor or a water bill that jumps $80 in one month. If you're searching for leak detection and repair Phoenix AZ near me, we run 24/7 water leak repair Phoenix AZ calls across the Valley with no overtime charges.

Practical benefits
Why Phoenix Homeowners Call Us First
A leak doesn't get better on its own. It gets more expensive. Here's what you get when you call us instead of waiting another month.
Stop the Water Bill Bleed
A slab leak can waste 10,000 gallons a month before you notice. We locate it the same day and stop the loss. Most customers see their next water bill drop back to normal within one billing cycle.
Minimal Access, No Demolition
We don't jackhammer a whole room. Acoustic listening and thermal imaging pinpoint the leak within 6 inches, so we open one small section of floor or wall. You keep your tile, your cabinets, and your weekend.
Same-Day Water Leak Repair Phoenix AZ
Most calls booked before 2 p.m. get same-day water leak repair Phoenix AZ service. We carry copper pipe, PEX pipe, and fittings on every truck, so we finish the repair in one visit instead of scheduling a return trip.
Protect Your Foundation
Water under a slab softens soil and shifts the foundation. A $400 repair today prevents a $12,000 foundation job later. We test the entire line after the fix so you know there's no second leak waiting.
How service works
How Our Leak Detection Process Works
Five steps, no guesswork. You'll know what we found, what it costs, and how long it takes before we pick up a tool.
Phone Intake
You call (602)533-0560 and tell us what you're seeing: a hot spot on the floor, a spike in the water bill, a sound behind the wall. We ask three or four questions, give you a ballpark range, and book a two-hour arrival window. No dispatch fee.
Tools and methods
Tools and Methods We Use
Acoustic Listening Equipment
Picks up the hiss of pressurized water escaping a pipe under a slab. We use it to narrow the leak to a 6-inch circle before we open anything.
Thermal Imaging Camera
Shows temperature differences on floors and walls. Hot-water leaks glow on the screen, and it also reveals hidden moisture behind drywall.
Pressure Gauge
Confirms there's a leak and which side of the system it's on. We hold pressure for 30 minutes after every repair to verify the fix.
RIDGID Sewer Camera
Inspects drain and sewer lines for cracks, root intrusion, and joint failures that cause underground leaks.
Milwaukee Pipe Cutter and Soldering Torch
Clean cuts and solid joints on copper pipe. We solder or crimp every repair and pressure-test before closing up.
Hydro Jetting Machine
Clears grease, scale, and roots from drain lines so we can inspect the pipe wall for the cracks that cause leaks.
Drain Snake and Auger
Handles smaller clogs and lets us check the trap and drain connections for the slow leaks that warp cabinets.
Pressure Isolation Testing
We shut off every fixture and pressurize the main line. If the gauge drops, there's a leak on the supply side. If it holds, the problem is on the drain side or a fixture. This takes 15 minutes and saves hours of guessing.
Acoustic Pinpointing
We walk the line with a listening disc and mark the loudest point on the floor. Copper pipe under a slab makes a distinct hiss at 40-60 PSI. We confirm the spot with thermal imaging before we cut.
Thermal Mapping
The thermal camera shows hot and cold spots on floors and walls. Hot-water slab leaks show up as a warm patch. Cold-water leaks show up as a cool patch. We use it to confirm what the acoustic gear found.
Uniform Plumbing Code Compliance
Every repair is done to Uniform Plumbing Code and International Plumbing Code standards. That matters for permits, inspections, and resale. We pull permits when the job requires it.
Post-Repair Pressure Verification
After the repair, we re-pressurize the line and hold it for 30 minutes. If the gauge moves, we keep working. You don't pay until the line holds steady and the meter stops.

Where this service fits
When to Call for Leak Detection
Your water bill jumped $60 or more in one month with no change in usage.
We pressure-test the main line, then walk it with acoustic and thermal gear to find the source. Most hidden leaks show up in under 30 minutes of scanning. You get a located leak, a repair quote, and usually a same-day fix. Next bill drops back to normal.
You hear running water when every fixture in the house is off.
That sound is almost always a slab leak or a toilet fill valve. We isolate the fixtures first, then scan the slab if the fixtures check out clean. We find it, fix it, and pressure-test the line. The sound stops and stays stopped.
There's a warm spot on the floor, or the tile feels loose in one area.
A hot spot on the floor is a classic hot-water slab leak. We confirm it with thermal imaging, mark the spot, and open one small section of floor to repair the line. One small repair, no full-room demolition. The floor goes back down and the hot spot is gone.
Your water meter keeps spinning after you shut off every valve in the house.
That confirms a leak on the main line or under the slab. We pressure-test to isolate which side, then scan the affected run with acoustic gear. We locate the leak, repair it, and verify the meter stops. You know exactly where the water was going.
You're buying or selling a Phoenix home and the inspection flagged moisture.
We run a full leak inspection, document the findings with photos, and give you a written report you can hand to the buyer, seller, or agent. Clean paperwork for the transaction, plus a repair quote if something needs fixing before closing.

How Leak Detection Runs in Phoenix
Phoenix is hard on plumbing. Our water is mineral-heavy, the ground shifts with clay soil, and summer attic temperatures hit 140 degrees, which cooks supply lines and shut-off valves. Copper pipe from the 1970s and 1980s develops pinhole leaks, and slab leaks are common in ranch homes from that era. We handle leak detection Phoenix AZ calls every week in neighborhoods like Arcadia, Coronado, and Maryvale, where the housing stock is older and the pipe is at the end of its life. If you're searching for slab leak detection Phoenix Arizona or underground leak detection Phoenix AZ, we run acoustic gear and thermal cameras on every truck. We also work to Arizona ROC Plumbing License standards and pull permits when the job requires it, so your repair passes inspection the first time.
Willo Historic District
1920s and 1930s homes with original galvanized pipe that's often been partially repiped. We check the transition joints first.
Arcadia
Ranch homes from the 1950s and 1960s with copper pipe that develops pinhole leaks. Slab leaks are common in the older sections.
Maryvale
Mid-century builds with original copper and clay sewer lines. Root intrusion and slab leaks are the two most common calls.
Desert Ridge
Newer construction with PEX pipe. Leaks here are usually at fittings or from irrigation line breaks, not the pipe itself.
Ahwatukee Foothills
Homes built on sloped lots, which means underground leaks can travel before surfacing. We use acoustic gear to trace the path.
Hard water with high mineral content
Scale builds up inside copper pipe and shortens its life. Pinhole leaks show up years earlier than they would in softer water.
Clay soil that expands and contracts
The ground moves with every wet and dry cycle, which stresses buried lines and causes joint failures. Underground leak detection Phoenix AZ calls spike after monsoon season.
Summer attic temperatures above 140 degrees
Supply lines and shut-off valves in attics degrade faster. We check attic runs on every leak call, even when the leak is under the slab.
Monsoon season from June through September
Heavy rain saturates the soil and reveals existing underground leaks. We run extra crews during monsoon to handle the call volume.
Problems we solve
Leak Problems We Solve Every Week
Most Phoenix leak calls fall into four buckets. Here's what we see, what happens if you wait, and how we fix it.
Slab leak under the foundation
We locate the leak with acoustic listening and thermal imaging, open one small section of floor, repair the copper or PEX line, and pressure-test before we pour new concrete. Most slab leak repairs finish in one day. Water softens the soil under your slab, which shifts the foundation and cracks tile. A $400 repair today prevents a $12,000 foundation job later.
Pinhole leaks in aging copper pipe
We repair the failed section first, then give you an honest read on the rest of the line. If repiping makes more sense, we quote it with no pressure. If a patch will hold, we patch it. One pinhole is a warning. Two or three in a year means the whole run is failing, and you'll be patching forever until you repipe.
Hidden wall leak behind tile or drywall
We use thermal imaging to find the leak without tearing out the whole wall. Then we open a small access panel, repair the pipe, and check the surrounding framing for water damage before we close up. Water runs down the inside of the wall, rots the framing, and grows mold. By the time you see a stain, the damage is usually $2,000 or more.
Underground leak in the main service line
We run underground leak detection Phoenix AZ calls with acoustic gear and a pressure gauge on the main. Once we mark the spot, we dig one hole, repair the line, and backfill the same day. The leak runs 24/7 under your yard, driving up the water bill and eroding the soil around the line. Left alone, the line eventually fails completely.
A practical standard for every visit.

Notes from local customers
What Phoenix Customers Say
Our water bill jumped $90 in one month and we had no idea why. The tech found a slab leak under the hallway in about 25 minutes with a listening disc. He opened one small square of floor, repaired the copper, and pressure-tested it twice. Bill's back to normal and you can't even tell where they worked.
Called at 11 p.m. with water coming up through the garage floor. They had a tech here in about 70 minutes. He shut off the main, found a burst line, and had it repaired by 2 a.m. No overtime charge, which I honestly expected. Straight shooters.
We manage six duplexes in Phoenix and use these guys for every leak call. They show up when they say, they document everything with photos, and the pricing is the same every time. Last month they caught a hidden leak in a wall that two other companies missed.
Leak detection in Phoenix AZ runs $180 to $450 for a standard residential call, depending on whether it's a slab leak, a wall leak, or an irrigation line. If we do the repair the same day, we often roll the detection fee into the repair cost. You'll get the full number before we start.
The four biggest signs are a water bill that jumps more than $50 in one month, a hot spot on the floor, the sound of running water when every fixture is off, and a water meter that keeps spinning with the main shut off. Any one of those means call us. Two or more means call today.
Yes. We run 24/7 water leak repair Phoenix AZ calls, including nights, weekends, and holidays. Call (602)533-0560 and we'll dispatch the nearest crew. Most emergency calls in Phoenix get a technician on site within 60 to 90 minutes.
We pressurize the line with a pressure gauge, then walk it with acoustic listening equipment and a thermal camera. Copper pipe under a slab hisses at 40-60 PSI, and thermal imaging shows the temperature difference. We mark the spot, open one small access point, repair the pipe, and pressure-test before we close up.
