Leak Detection Frequently Asked Questions
Everything you need to know about leak detection and plumbing services at Delta Plumbing.
How do I know if I have a hidden water leak in my home?
You usually do not see the water itself. You see the side effects. A jump in your water bill that you cannot explain, a damp or warm spot on the floor, a musty smell that will not go away, mold or mildew showing up where it should not be, the faint sound of running water with every fixture turned off, low pressure at one or two faucets, or a green patch in the yard that stays green through a dry week. Any one of these is worth a phone call. Two or more usually means you have a hidden leak that needs attention before it gets expensive.
Why is my water bill suddenly so high?
In our experience, a sudden, unexplained jump in a water bill is one of the strongest signs of a hidden leak. A failing toilet flapper, a slab leak, a pinhole in a copper supply line, or a leak in the buried line between your meter and your home can all push a bill up by 30, 50, even 100 dollars in a single month. If your bill jumped and your habits did not change, do not pay it and forget it. Call us. The free leak detection visit will tell you exactly where the water is going.
What is a slab leak, and how worried should I be?
A slab leak happens when a copper or PEX line running underneath your concrete foundation cracks, corrodes, or shifts. Because the leak is underground, it can run for weeks or months before anyone notices. By that point you may be looking at warm or wet floor tiles, foundation cracks, mold inside the walls, and a much bigger repair bill. The good news is that with thermal imaging and acoustic locating, our team can find a slab leak without breaking up your floor to look for it. The earlier you call, the smaller the repair.
Is leak detection at Delta Plumbing really free?
Yes. For residential customers in our Metro Atlanta service area, the initial leak detection visit is free. That covers the technician’s time, the use of our acoustic and thermal imaging equipment, and a written report on what we find. If you decide to move forward with a repair, we give you a separate written estimate before any work starts. No surprises, no after hours surcharge, no pressure to commit on the spot.
Will you have to tear up my floors or walls to find the leak?
No. The whole point of professional leak detection is to skip the demolition. We use sound, heat, and pressure to narrow the leak to a precise location, often within an inch or two. Only after we know exactly where the leak is do we open a small section of wall, floor, or concrete, and only at that one spot. Most of our customers are surprised at how small the repair area ends up being.
What kind of equipment do you use to find leaks?
We use professional grade acoustic listening equipment, including the Aquaphon A200, to hear the sound of water escaping a pressurized pipe even through concrete. We pair that with thermal imaging cameras that spot the temperature differences caused by hot or cold water leaks behind walls, ground microphones for buried supply lines, and tracer gas for situations where acoustic detection alone is not enough. The combination is what lets our techs find leaks that other companies cannot.
How long does a leak detection visit usually take?
Most residential leak detection appointments run 60 to 90 minutes from arrival to written report. A simple in wall leak can be confirmed in under an hour. A buried supply line that runs from the meter all the way to the house can take longer, and commercial systems with larger pipe networks can take longer still. We will give you a realistic time estimate when we book the appointment so you can plan your day.
Can you find leaks under driveways, patios, or in the yard?
Yes, and we do this often in Metro Atlanta. We use ground microphones and acoustic locating equipment to listen for the sound of escaping water through asphalt, concrete, and soil. Once we pinpoint the leak, we can usually repair it with minimal digging. In many cases we can do a trenchless repair or replacement instead of trenching the entire line, which keeps your driveway, walkway, or yard intact.
Can you locate a gas leak, too?
Yes. If you smell gas, leave the home first and call your utility. That is the safety step that always comes first. Once the home has been cleared as safe, our licensed technicians can locate gas line leaks using combustible gas detectors and tracer gas, then make the permanent repair to bring the line back into code. Gas line work is a separate service from water leak detection, but we handle both under one roof.

Reliable, Licensed Leak Detection, Available Around the Clock
Our background-checked Atlanta leak detection technicians arrive on time and explain every job upfront with flat-rate pricing. No surprise charges. No shortcuts. Just honest leak detection service from a company Metro Atlanta homeowners have trusted since 1974. Full-service leak detection is available for homes and businesses 24 hours a day, 7 days a week.
A hidden leak in an Atlanta home rarely waits for business hours, and the longer it sits, the more it costs. Red Georgia clay holds moisture against your foundation, slab leaks quietly undermine pier-and-beam crawl spaces, and a slow drip behind drywall can rot framing in a matter of weeks. That is why we run fully staffed leak detection trucks 24/7 across Fulton, DeKalb, Cobb, Gwinnett, and the surrounding counties, dispatched with electronic amplifiers, thermal imaging, and tracer gas equipment that locates the leak without breaking up your floors or yard.
When we arrive, you get a real diagnosis and a flat-rate price before any work starts. Our plumbers are licensed in Georgia, drug-tested, and trained on the same equipment used by municipal water departments. Whether it's a slab leak in a Sandy Springs ranch, a main-line break under a Decatur driveway, or a slow rise on the water bill of a Buckhead high-rise, the number on your invoice is the number you'll pay. That's what fifty-plus years of serving Atlanta has taught us: do it right, do it once, and stand behind it.

Every Kind of Hidden Leak, Located Without Demolition
Unexplained high water bills, slab and foundation leaks, leaks under driveways and underground, gas line identification, and leaks behind walls and ceilings. Here is how we track down each one.
Slab Leak Detection
A slab leak happens when a copper or PEX line running underneath your concrete foundation cracks, corrodes, or shifts. Because the leak is underground, it can run for weeks or months before anyone notices. By then you may see warm or wet floor tiles, foundation cracks, and mold inside the walls, and the repair bill grows with every week.
With thermal imaging and acoustic locating, our team finds a slab leak without breaking up your floor to look for it. We open concrete only at the one spot we've confirmed. The earlier you call, the smaller the repair.
- Warm spots on tile or hardwood
- Cracks in the foundation or flooring
- The sound of running water with every fixture off
Underground, Yard & Driveway Leaks
We find leaks under driveways, patios, and yards often across Metro Atlanta. Ground microphones and acoustic locating equipment let us listen for escaping water through asphalt, concrete, and soil. That includes the buried supply line between your meter and your home.
Once we pinpoint the leak, we can usually repair it with minimal digging. In many cases a trenchless repair or replacement replaces trenching the entire line, which keeps your driveway, walkway, or yard intact.
- A green patch that stays green through a dry week
- Soggy spots or sinking soil
- A meter that keeps spinning with the water off
Leaks Behind Walls & Ceilings
A slow drip behind drywall can rot framing in a matter of weeks. Thermal imaging cameras spot the temperature differences that hot or cold water leaks cause behind walls and above ceilings, and acoustic equipment confirms the line. A simple in-wall leak can often be confirmed in under an hour.
Only after we know exactly where the leak is do we open a small section of wall, at that one spot. Most of our customers are surprised at how small the repair area ends up being.
- Stains, bubbling paint, or soft drywall
- A musty smell that won't go away
- Mold or mildew where it shouldn't be
Gas Leak Location & Gas Line Identification
If you smell gas, leave the home first and call your utility. That safety step always comes first. Once the home has been cleared as safe, our licensed technicians locate gas line leaks using combustible gas detectors and tracer gas, then make the permanent repair to bring the line back into code.
Gas line work is a separate service from water leak detection, but we handle both under one roof, including gas line identification before you dig or remodel.
- A sulfur or rotten-egg smell
- Hissing near a gas line or appliance
- Dead plants above a buried gas line
Found a leak sign? Let's pinpoint it before it spreads.
Damp drywall, a jumpy water bill or a warm spot on the floor. We locate the source without tearing things apart, with upfront flat-rate pricing.
See the Leak Before You Open the Wall
Water changes the temperature of whatever it touches. A leaking hot-water line warms the slab or drywall around it; a cold line cools it. Our thermal imaging cameras read those differences across a whole room in seconds, so we can trace a supply line through a wall or floor and spot where the pattern breaks.
Thermal imaging narrows the search. Acoustic listening then confirms it. The combination is what lets our techs find leaks that other companies cannot.
- Thermal imaging cameras spot heat signatures from hot or cold water leaks behind walls and under floors.
- Electronic amplifiers & ground microphones hear buried supply lines through soil, asphalt, and concrete.
- Tracer gas for situations where acoustic detection alone is not enough.
- Pressure testing confirms which line is losing water.
We Listen for the Leak, Even Through Concrete
We use professional-grade acoustic listening equipment, including the Aquaphon A200, to hear the sound of water escaping a pressurized pipe even through concrete. It's the same kind of equipment municipal water departments rely on, and it lets us narrow a leak to a precise location, often within an inch or two.
Why is my water bill suddenly so high?
In our experience, a sudden, unexplained jump in a water bill is one of the strongest signs of a hidden leak. A failing toilet flapper, a slab leak, a pinhole in a copper supply line, or a leak in the buried line between your meter and your home can all push a bill up by 30, 50, even 100 dollars in a single month. If your bill jumped and your habits did not change, don't pay it and forget it. Our high water bill audit tells you exactly where the water is going.
