The worst leaks are the ones you can't see. A pipe behind a wall, under the slab, or out in the yard can run for weeks — quietly rotting framing, feeding mold, and inflating your water bill — before anything visible gives it away.
We find those leaks without tearing your house apart. Using electronic and acoustic equipment, we listen for and pinpoint the exact spot before we open anything up. That means a small, targeted repair instead of guesswork and drywall demolition. Whether it's a slab leak, a leak inside a wall or ceiling, or a break in the underground service line, we locate it precisely and fix it right.
Signs You Have a Hidden Leak
Hidden leaks announce themselves indirectly. Any of these is worth a call:
- A water bill that jumped for no reason you can explain
- The sound of running water when every fixture is off
- Warm spots on the floor, or a section of slab that's oddly warm underfoot
- Damp, discolored, or bubbling patches on walls or ceilings
- A musty, mildew smell that won't go away
- Low water pressure that's crept in over time
- Cracks in the foundation or unexplained shifts in the floor
The Water-Meter Test You Can Run Now
Before you call anyone, there's a simple check that tells you whether water is escaping somewhere. Turn off every fixture and water-using appliance in the house. Then go find your water meter and watch the dial or the small leak indicator.
If it's still moving with everything shut off, water is going somewhere it shouldn't — you have a leak. For a slower confirmation, write down the meter reading, avoid using any water for an hour or two, and check it again. A number that climbed with no usage is proof. Our guide on how to detect a hidden water leak walks through this step by step, and a leak that's also dragging down your pressure lines up with the culprits in our post on low water pressure causes.
Once you know a leak exists, finding exactly where it is is our job — and that's where the right equipment saves you a fortune in unnecessary demolition.
- Shut off every fixture and appliance in the home
- Watch the meter's leak indicator for movement
- Or record the reading, wait, and check for a change
- Any movement with everything off means you have a leak
How We Pinpoint the Leak
The old way to find a hidden leak was to start cutting and hope. We don't work that way. We use electronic and acoustic listening equipment that hears the specific sound of water escaping a pressurized pipe, even through concrete and drywall. That lets us narrow a leak down to a small area before we ever open anything.
Slab leaks — pipes running under the concrete foundation — are among the trickiest, and they're exactly where non-invasive detection pays off. Instead of jackhammering across the floor, we find the one spot that matters. Same with a leak inside a wall or ceiling: we locate it, open just what we need to, make the repair, and leave you with a small patch instead of a gutted room.
Underground service-line leaks between the meter and the house get the same treatment. We trace the line and pinpoint the break so any digging is minimal and targeted.
Repair, Repipe, or Emergency
Finding the leak is half the job; fixing it right is the other half. Sometimes it's a single spot repair. But if we're finding leaks in old galvanized or aging copper — common in Indianapolis's historic neighborhoods — a spot fix may just be the first of many. In that case we'll be straight with you about whether pipe repair or a repipe is the smarter long-term move, and our post on the signs you need repiping covers when patching stops making sense.
Some leaks are quiet; others are emergencies. A line that lets go and floods a room is exactly the kind of thing our 24/7 emergency team handles day or night. And if what looks like a plumbing leak turns out to be the sewer line, we can run a camera and move into sewer line repair instead. We work in homes all over the area, from Meridian-Kessler to the suburbs, so we know the pipe you're likely dealing with before we arrive.
Where Indianapolis Homes Spring Leaks — and Why
The cause of a leak usually ties back to a home's age and our climate. In older neighborhoods, galvanized supply lines corrode from the inside until they pinhole, and decades-old copper can develop the same. Winter is its own hazard — a pipe in an unheated crawlspace, garage, or exterior wall can freeze, split, and only reveal itself when it thaws. Slab homes hide leaks under concrete, where a failed line can run unseen for months.
Catching leaks early protects both your home and your wallet. If yours traces to corroded, failing supply lines, spot repairs may give way to pipe repair and repiping for a lasting fix. Our guide on finding a hidden leak walks through the warning signs, and in freeze season, a little prevention keeps a small drip from becoming a burst-pipe emergency.
What Affects the Cost of Leak Detection & Repair
Detection and repair are two parts of one job. We quote clearly and upfront once we understand the situation. What shapes it:
- Where the leak is — an accessible wall vs. under a concrete slab or underground
- How much detection work it takes to pinpoint the source
- The repair itself: a single spot fix vs. replacing a run of pipe
- The pipe material and the age of the plumbing
- Whether the leak has caused damage that needs addressing too
Pinpointing the leak first is what keeps the repair small and the bill honest. You'll get a clear price before we open anything up — no surprise demolition.

Leak Detection & Repair across Indianapolis & Central Indiana
Hidden leaks turn up in every kind of home, and where we look depends on how it was built. In older Indianapolis neighborhoods like Meridian-Kessler and Irvington, aging galvanized and copper lines corrode and weep behind plaster. In slab-built ranches around Greenwood and Fishers, we chase leaks under concrete before they surface. We cover Marion, Hamilton, Hendricks, and Johnson counties, bringing the right tools to find water no matter where it's hiding.
