Kennesaw homes are mostly from the 1990s and 2000s, so repiping here usually means replacing polybutylene or a failing copper or CPVC branch rather than old galvanized. A plumber replaces pipe from the Cobb County meter to the fixtures. Call the number on this page to be connected with a local plumber in Kennesaw.
Kennesaw at a glance
The median Kennesaw home was built in 1998, and about 11% predate 1980, according to Census survey data. Houses from the late 1980s and early 1990s are the ones most likely to have polybutylene; later homes more often have CPVC or PEX, where problems tend to be isolated.
Cobb County Water System supplies Kennesaw with water bought from the Cobb County-Marietta Water Authority and disinfected with free chlorine. Cobb owns the line up to the meter, and the owner has the rest. Kennesaw Building Services enforces the 2024 International Plumbing Code with Georgia amendments, and all permits are applied for online.
First steps to take
- Find the main shutoff and make sure it turns, so you can stop water quickly if a pipe lets go.
- Write down every leak you've had, with dates and rooms, along with any past repairs.
- Look at the pipe beside the water heater and under a sink and note the color and material.
- Look up your home's service line material at cobbcounty.gov/WSLI so you know what feeds the house.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Soggy patch between meter and house | Failing buried service line |
| Leak returns near the same fitting | Corrosion at joints spreading along an old run |
| Blue-green stains at joints | Copper fittings corroding |
| Weak flow everywhere, worst upstairs | Galvanized pipe narrowed by internal buildup |
| Stains on a ceiling under a bathroom | Leak on a supply branch above |
| Gray plastic pipe or fittings that crack | Polybutylene nearing the end of its life |
| Water heater outlet pipe rusted through | Mixed metals corroding where they meet |
What moves the number up or down
- Phased or all at once: doing one branch now and the rest later spreads cost but adds trips.
- Access obstacles: built-in cabinets, finished ceilings or a tight crawl space slow the routing.
- Wall and ceiling finishes: plaster, tile backsplashes and finished basement ceilings take more care to open and close.
- House size and fixture count: every bathroom, kitchen, laundry hookup and hose bib adds runs and fittings.
- Pipe material: PEX usually takes fewer labor hours than soldered copper, and CPVC sits somewhere between.
- Extras done at the same visit: new shutoff valves, a pressure-reducing valve or water heater connections add parts and time.
- Foundation type: a crawl space gives open access underneath, while a slab pushes new lines up into walls and the attic.
- Number of stories: upstairs bathrooms mean longer vertical runs and more places to open walls.
- Patching after the work: some quotes include drywall patching and others stop at rough repair, so ask.
