PINPOINT BEFORE YOU DIG
Leak Detection in Chattanooga, TN
A rising water bill, a warm spot on the floor, or a sound of running water with everything off, tracked down before anything gets opened up. Water actively causing damage right now is a same-day, even 24/7 emergency call, not a wait-and-see.
Why a Chattanooga leak is often hidden rather than obvious
A supply leak in this city rarely announces itself the way it would in a house with a simple slab and a shallow yard line. Between hillside lots with basements, crawl space homes on grade. Slab houses further out toward the county line, the pipe run from the meter to the house and the pipe run inside the walls can each hide a leak for weeks before it shows up as a stain, a soft spot, or a bill that suddenly does not match the season. Add limestone-influenced water moving through older galvanized pipe in the historic neighborhoods and the leak is sometimes at a corroded joint that was never going to be visible without acoustic or thermal equipment.
The good news is that a real leak almost always leaves a measurable trace even when it is not visible. A meter that keeps turning with every fixture in the house shut off is proof water is going somewhere. From there the question is whether it is going into the yard, under the slab, or inside a wall, not whether a leak exists at all.
Reading the signs before we arrive
| Sign | Likely cause | What to do |
|---|---|---|
| Meter spins with everything off | Confirmed leak somewhere on the property | Note the time and re-check it in fifteen minutes |
| Warm spot on a slab floor | Likely a hot water line leaking under the slab | Do not walk on it repeatedly, mark the spot |
| Green patch or soggy ground in the yard | Leak on the line between the meter and the house | Photograph it, especially after a dry stretch |
| Sound of running water with taps off | Often a toilet fill valve or a hidden supply leak | Check each toilet tank first, it is the most common false alarm |

Call (423) 810-4269.How we actually find it without opening the whole house
Acoustic listening equipment picks up the specific sound pressurized water makes escaping a pipe, and it works through slab, drywall. Most flooring, which is why the vast majority of leaks get pinpointed to a small target area rather than a room. For a leak that acoustic equipment cannot isolate cleanly, thermal imaging can show the temperature difference a hot water leak leaves behind under flooring. Tracer gas is the fallback for a leak that is genuinely quiet.
None of this replaces the meter test as the starting point. Shutting off every fixture and watching the meter for fifteen minutes tells us whether we are chasing a real leak or something else, like a running toilet, before any specialized equipment gets involved. This Keeps the diagnostic cost proportional to the actual problem.
Older neighborhoods versus newer construction
In North Shore, St. Elmo, and the other pre-war neighborhoods, a leak detection call frequently ends at a pinhole in galvanized supply pipe that has been quietly narrowing and corroding from the inside for decades. Further out in the newer subdivisions built on the ridges and toward the county line, the leak is more often a fitting failure or a nail through a PEX line during some other renovation, a different problem with a different fix. This Is part of why we ask about the age and construction of the house before diagnosing anything over the phone.
QUESTIONS
Frequently asked
How do you find a leak without tearing out drywall or flooring?
Acoustic and thermal equipment locate the leak to a small area first, so any opening we make is targeted rather than exploratory. There are cases, mostly slab leaks under thick or layered flooring, where a small access opening is genuinely the only reliable way to confirm the exact point. We will tell you that plainly before doing it rather than after.
My water bill went up but I cannot find anything wet anywhere.
That is actually the most common leak-detection call we get. It usually means the leak is under the slab, in the yard line, or inside a wall cavity where it has not surfaced yet. The meter test is still the right first step, and from there acoustic equipment narrows the search.
Is a leak on my side of the meter or the water company's?
Everything from the meter to your fixtures is your responsibility; the line from the main up to the meter is the utility's. If the leak turns out to be on their side, we will tell you that rather than charge to fix something outside your property.
Could it just be a running toilet?
Often, yes. A worn flapper or fill valve can waste hundreds of gallons a day without any visible sign. Checking every toilet tank is one of the first things we do before assuming a bigger leak.
