HomePlumbingLeak Detection

Hidden water leak detection in Dayton & Cincinnati.

Water is going somewhere and you cannot see it. We listen for it and look for its heat, so a leak under your slab or inside a wall gets narrowed to inches before anyone cuts anything open.

Most people find a leak on the water bill before they find it on the floor. We find it without tearing up the house.

WHAT WE DO

Find it, fix it, verify it.

How do I know if I have a hidden leak?

Run the house dry: turn off every fixture and appliance that uses water, then watch the meter for fifteen minutes. If the dial moves at all, water is going somewhere. That test costs nothing and it is the first thing we will ask whether you tried.

Do it before you call. If the dial moved, you have your answer and we can skip straight to finding where.

Why did my water bill double with no leak I can see?

A leak that never reaches a visible surface still runs through the meter. The usual culprits are a toilet flapper passing water silently, an irrigation line, a slab leak under the floor, or a service line between the meter and the house. All four are invisible and all four bill.

Find your symptom in the left column. It usually names the location before any equipment comes out of the van.

Leak symptoms, likely location, and how each is found.

Can you find a leak without opening walls?

Usually. Acoustic listening equipment picks up pressurized water escaping a line through drywall, tile and concrete, and thermal imaging shows where a hot line is heating the floor above it. That narrows the search to inches, so when something is opened, it is one small access hole and not a wall.

What is a slab leak and how bad is it?

A slab leak is a supply line failure under the concrete floor of a house built on a slab. Signs are a warm patch of floor, an unexplained bill, or the sound of running water with everything off. Left alone it saturates the soil under the foundation, which is the expensive part, not the pipe.

We find it with thermal imaging first. No concrete gets opened until we know which foot of pipe we are opening it for.

What gets documented when a leak is found?

The source and the moisture readings are photographed before the repair, and the line is pressure-tested afterward. That record is what a claim or a future buyer asks for, and it is produced whether or not anyone ends up needing it.

How fast can a leak be found and fixed?

Detection is usually one visit, and most leaks get located and repaired in the same appointment unless the fix means opening a slab or replacing a run of line. Most calls are handled the same day. Call (844) 584-7399, or the emergency line if water is moving right now.

LEAK QUESTIONS

What else do homeowners ask about hidden leaks?

Turn off every fixture and appliance that uses water, then watch the meter for 15 minutes. If it moves, you have a leak. The test is free and it is the fastest answer you can get without anyone coming out.
In most cases, yes. Acoustic and thermal detection narrows a hidden leak to within a few inches before anything is opened, so a repair usually means one small access point rather than an exploratory demolition.
A toilet flapper that passes water silently can waste about 200 gallons a day, which is why a bill can double with nothing visible anywhere in the house.
It can be condensation, a leaking T&P valve, or the first sign of a tank failing at the bottom seam. All three look the same on the floor and only one of them is harmless, so it is worth a look before the tank opens up.
Both, under Ohio plumbing license #13557. The line gets pressure-tested after the repair, before anyone leaves.
