Kennesaw sits north-west of Marietta along the I-75 and Barrett Parkway corridors, and its housing is a broad mix of 1980s-2000s subdivision development with an older historic core. That build profile determines what leaks turn up: pipe material tracks construction date closely, and foundation type decides how quickly a leak reveals itself. Kennesaw is served by Cobb County Water System, so the county's leak adjustment process applies once a leak is repaired and documented.

Housing in Kennesaw and what it means
Kennesaw's housing is a broad mix of 1980s-2000s subdivision development with an older historic core. Pipe material follows build date closely: roughly 1978-1995 means polybutylene is likely, the 1960s to 1980s often means copper run under slabs, and anything older can still carry galvanized steel supply and cast iron drains.
The leak profile here
The leaks most often found in Kennesaw:
- Polybutylene in the 1980s and early-90s subdivisions
- Buried service line leaks on the larger newer lots
- Irrigation leaks across extensive subdivision systems
- Galvanized and cast iron issues in the historic downtown core
In practice that means the same work we do across Marietta, done in Kennesaw: slab leak detection under concrete, water service line leaks between the meter and the house, pool leak detection, irrigation leaks and sewer and drain problems. A slab leak in Kennesaw behaves exactly as it does in Marietta, because the housing eras and the red clay underneath are the same.
| Most common leak type | Why, in this area |
|---|---|
| Polybutylene | Polybutylene in the 1980s and early-90s subdivisions |
| Buried service line leaks on the larger newer lots | Buried service line leaks on the larger newer lots |
| Irrigation leaks across extensive subdivision systems | Irrigation leaks across extensive subdivision systems |

The paperwork that decides whether you get money back
The part homeowners most often get wrong is not the detection or the repair. It is closing the job out with nothing in writing.
Both utilities want evidence the problem was corrected: a plumbing repair invoice, a receipt for parts, or at minimum a letter describing what was wrong and what was done. An insurer wants more than that, and wants it before the damage is cleaned up.
Photograph the meter reading, the damp, the opened area and the finished repair. Ask for a written leak detection report before the work closes, not after, because it cannot be recreated once the hole is filled in.

Describe the sound, the damp patch or the bill and we will tell you what it usually means in a Marietta home and what it takes to confirm it.
What actually happens on a detection visit
Leak detection is a process of elimination, not one gadget. The cheapest method that can answer the question is used first, and nothing is opened until the location is confirmed twice.
Pressure testing proves which line is losing. A locator maps where the pipe genuinely runs, which is frequently not where anyone assumed. Acoustic ground microphones pick up the hiss of pressurized water escaping through concrete and soil.
Then a second, independent method confirms it: thermal imaging for hot-side leaks, tracer gas for anything too small or too quiet to hear. Only then does the marking pen come out.
What it costs, and why guessing costs more
Detection in this market is normally a flat diagnostic fee rather than an hourly rate, and it is quoted separately from the repair, because until the leak is located nobody can honestly price fixing it.
The reason the diagnostic is worth paying for is arithmetic. Opening a slab, a wall or a driveway in the wrong place costs more than the diagnostic that would have avoided it, and the leak is still unfound afterwards.
Ask three things before booking: what the fee covers, whether it is credited against a repair, and what happens if no leak is found. The cost guide sets out the market ranges.
Which water utility bills you here
Kennesaw is served by Cobb County Water System, which allows a partial leak credit once per rolling 12-month period across no more than two affected months. You must supply your account address and number, a brief explanation of the leak, and a plumbing repair receipt, a receipt for parts, or at minimum a letter explaining what was done. Pool leaks also require the pool volume, and you remain responsible for the bill while the claim is processed.
Before you call anyone
Run the water meter test first. With every fixture and appliance off, any movement of the low-flow indicator means water is escaping. Closing the main house shut-off and re-checking then tells you whether the leak is inside the house or out in the buried service line. It costs nothing and it narrows the problem more than any other single step.
We work in Kennesaw from our Marietta base, so this is part of our regular service area rather than a long call-out. What a visit costs is the same here as anywhere else we cover: see what leak detection costs.
Frequently asked questions
Do you cover Kennesaw, GA?
Yes. Kennesaw sits north-west of Marietta along the I-75 and Barrett Parkway corridors and is within our regular service area from our Marietta base.
What leaks are most common in Kennesaw?
Polybutylene in the 1980s and early-90s subdivisions, along with buried service line leaks on the larger newer lots. Housing era and foundation type determine the pattern more than anything else.
Which water utility serves Kennesaw?
Cobb County Water System, so the county's leak adjustment process applies rather than the Marietta Power & Water one. Confirm by checking the utility name printed on your bill.
What if the leak cannot be found?
Ask that question before booking anyone, because the answer separates specialists from guessers. A reputable operator will tell you in advance what happens to the fee, and will document what was ruled out rather than leaving you with nothing.
Will my homeowners insurance pay for this?
Usually only as part of a covered loss, not as a standalone inspection. Where a leak has caused damage the policy covers, insurers commonly pay to locate it, reach the pipe and restore what was opened. Gradual deterioration is the exclusion that most often applies.
