If a pipe bursts in your Kennesaw home, close the main shutoff and keep clear of wet electrical. A plumber can cut out the damaged section and splice in new pipe. Call the number on this page to be connected with a local plumber in Kennesaw.

Kennesaw doesn't run its own water system; Cobb County Water System serves the city. Cobb owns and maintains the line from the main to the meter, and the pipe from the meter to the house is the property owner's. For a broken line at the meter or in the street, call Cobb's emergency number, 770-419-6201. The median Kennesaw home dates to 1998 and only about 11% predate 1980, so freeze breaks here usually involve attic, garage or exterior-wall lines. Permits come from the City of Kennesaw's Building Services Department, which enforces the 2024 International Plumbing Code with Georgia amendments and takes all applications online.
What to do right now
- Shut off the water at the main valve, usually near where the line comes into the house. If the house valve fails, the meter box holds a second valve that needs a meter key.
- Document the leak with pictures and a short video before you start drying anything out.
- Clear the area, soak up standing water and start fans if it is safe to do so.
- Open a downstairs tap and an outside spigot to empty what is left in the system.
- Put the water heater on hold: pilot setting for gas, breaker off for electric.
Reading the signs
| Symptom | Likely cause |
|---|---|
| Warm spot on the floor | Hot water line leaking under the floor or slab |
| Soggy strip of lawn toward the house | Break along the line from the meter |
| Water pouring from a pipe joint | A fitting pushed apart by freezing or high pressure |
| Low pressure everywhere, suddenly | A major break on the main line or service line |
| Water bill jump with no change in use | An unnoticed break leaking for weeks |
Why repair bills vary
- Upgrades done at the same visit, such as insulating the run or moving it away from an exterior wall.
- When you call. After-hours and holiday service usually carries a higher rate than a scheduled daytime visit.
- Where the pipe sits. Exposed runs are quick to reach; pipes behind cabinets, tile or ceilings add labor.
- The number of repairs. One crack is a short job; several along an outside wall add up.
- Digging. If the failure is on the buried line to the house, the job includes excavation.
- Pipe type and condition. Brittle or corroded pipe near the break may need a longer section replaced.
