Slab Leak Detection and Repair in Canton and Ball Ground, GA
A leak under the slab does not announce itself. The water bill does.
A slab leak is a pressurized water line or a drain line leaking under the concrete foundation of the house. There is nothing to see, which is why most Cherokee County homeowners find out from a water bill that doubled, a warm patch on a tile floor, or the sound of water running when every tap is off. Performance Plumbing locates slab leaks without tearing up floors to look, and repairs them with the least demolition the job allows. No service call fee for the visit, the location marked before anyone cuts concrete, and a flat rate quote in writing.
What we do
- Slab leak detection with pressure testing, acoustic listening equipment and thermal imaging, so the leak is pinpointed to the foot before any concrete is opened.
- Spot repair through the slab: open the floor over the leak, repair the line, close and restore the concrete.
- Rerouting the failed line through the walls or attic when the pipe under the slab is too far gone, which often beats cutting the floor at all.
- Whole home repiping when the slab leak is the third leak in a system that has reached its age. See repiping.
- Basement and crawl space leaks, which in Cherokee County are often the same job under a different floor.
- Drain line leaks under the slab, found with a camera and repaired the same way.
The signs you have a slab leak
- A water bill that jumped with no change in how you live.
- The sound of running water when every fixture is off.
- A warm or hot spot on a floor, which usually means the hot water line.
- Damp carpet, cupped hardwood, loose tile or a musty smell with no visible source.
- Low water pressure at every tap.
- Cracks appearing in the foundation, the drywall or the tile grout lines.
- Mold or mildew at the base of walls in the lower level.
- Water surfacing at the edge of the foundation outside.
The meter test is the one you can do yourself: shut off every fixture, read the water meter, wait thirty minutes, read it again. If it moved and nothing is leaking in the yard, the leak is likely under the house.
Why slab leaks happen in Cherokee County homes
Most of the slab leaks we repair are in homes from the 1970s through the 1990s with copper lines run under the slab. Copper reacts with the minerals and acidity in our water and soil and pits from the outside in, especially where the pipe rubs against gravel or rebar as the slab moves. North Georgia red clay swells and shrinks with the seasons, which shifts the slab and stresses the joints under it. Older homes may have galvanized steel that has rusted through, and homes from the polybutylene era have plastic lines that crack at the fittings. A pressure reducing valve that has failed makes all of it worse by pushing street pressure into pipe that was never designed for it.
Locate first, then the smallest honest fix
We do not cut concrete to look for a leak. We isolate the hot and cold sides, pressure test each, listen for the leak with acoustic equipment, confirm it with thermal imaging where the floor allows, and mark the spot. From there we recommend one of three things: a spot repair through the slab when the leak is a single point in an otherwise sound line, a reroute overhead when the line under the slab is pitted along its length, or a repipe when the slab leak is one of several failures in an aging system. You get the reasoning and a flat rate quote for the option we recommend, and the alternatives if you want them.
What slab leak repair costs, and why we do not print a number
A leak at a single point under a laundry room floor is a very different job from a hot line that has pitted under a tiled master bath. What moves the quote: where the leak is, what is on the floor above it, whether a spot repair or a reroute is the right fix, whether the line is hot or cold, and how much of the system has reached the same age. We locate the leak, show you, and give you one flat rate quote with nothing added later. There is no service call fee for the visit, and financing options are available for reroutes and repipes.

Slab leak questions, answered
How do you find a slab leak without digging up the floor?
We isolate the hot and cold lines, pressure test each side, listen for the leak with acoustic equipment and confirm with thermal imaging where the floor allows. The leak is marked on the floor before anything is opened.
Is a slab leak covered by homeowners insurance?
Policies vary. Many cover the damage a sudden leak causes and the access to reach it, but not the pipe repair itself. We document the leak location and the repair so you have what the adjuster needs.
Can a slab leak be repaired without breaking the slab?
Often, yes. Rerouting the failed line through the walls or attic avoids the floor entirely and is the better fix when the pipe under the slab is pitted along its length rather than at one point.
What is the warm spot on my floor?
Almost always a hot water line leaking under the slab. The warm water heats the concrete above it. That is the most common way Cherokee County homeowners find a slab leak.
How urgent is a slab leak?
Urgent. Water under a foundation erodes the soil that supports it and feeds mold in the walls above. The repair is far cheaper than the foundation and mold work that follows a leak left for months.
Do you charge a service call fee to find a slab leak?
No. We come out, locate the leak, and give you a flat rate quote before any work starts. If you decide to hold off, you owe us nothing.
Should I repair the slab leak or repipe the house?
One leak in an otherwise sound system is a repair or a reroute. A second or third leak in copper from the same era means the rest of the system is on the same clock, and a repipe is usually the better spend. We show you the pipe and the reasoning before you decide.
What about leaks under a basement or crawl space?
Same detection, usually an easier repair because we can reach the line. Many Cherokee County homes sit on basements and crawl spaces rather than slabs and we handle both.
Do you offer financing for slab leak repair?
Yes. Financing options are available for reroutes and repipes. Ask when you call, or see our financing page.
Which areas do you cover?
All of Cherokee County, including Ball Ground, Canton, Holly Springs, Hickory Flat, Woodstock and Waleska, plus Jasper and Big Canoe in Pickens County and the Cumming area in Forsyth County.
