Marietta Leak Locators is a leak detection company based at 2722 Sandy Plains Rd, Marietta, GA 30066. We locate hidden water, slab, pool, sewer and gas leaks across Marietta and Cobb County using non-invasive methods, pressure testing, line tracing, acoustic listening, thermal imaging and tracer gas, so that the smallest possible area has to be opened.
What we do
Our work is locating leaks accurately. That means confirming a leak exists, isolating which system it is on, tracing where the pipe actually runs, and then narrowing the failure to a point that can be marked on the floor or the ground, verified with a second independent method before anything is opened.
We also produce written documentation of what was found. That matters more than most homeowners realise, and both Cobb County Water System and Marietta Power & Water require evidence a leak was repaired before applying a leak credit, and insurers work from the cause and location recorded at the time.
Methods and equipment
- Pressure testing: proving which line is losing before anything else happens
- Zone isolation: narrowing the search by closing valves in sequence
- Line tracing: mapping where the pipe genuinely runs
- Acoustic listening and correlation: ground microphones and correlators for pressurised leaks
- Thermal imaging: confirming hot-side leaks and mapping moisture spread
- Moisture mapping: reading moisture through finished surfaces
- Tracer gas: for leaks too small or too quiet to hear
- Video pipe inspection: for drain and sewer lines

A note on the information on this site
That includes the cost guide, the high water bill triage, and the two utility leak credit guides for Cobb County and Marietta Power & Water.
The guidance published here on water utility leak credits, insurance coverage and typical market costs is compiled from public sources and published third-party data, and is provided for general guidance. It is not legal, insurance or financial advice, and cost figures are market ranges rather than quotes. Utility and insurer terms change, so always confirm current requirements directly with Cobb County Water System, Marietta Power & Water, or your own insurer.
Frequently asked questions
Where are you based?
2722 Sandy Plains Rd, Marietta, GA 30066. We cover Marietta and Cobb County, plus the surrounding communities of Kennesaw, Smyrna, Acworth, Powder Springs, Austell and Mableton.
Do you repair leaks as well as find them?
Contact us to discuss what a particular job involves. Detection and repair are separate pieces of work and are quoted separately, because until a leak is located nobody can honestly price the repair.
Will I get documentation of what you find?
Yes. Written documentation of the leak location, the methods used and the probable cause is part of the job, because you need it for a water utility leak credit application and for any insurance claim.
