A hidden leak shows up on your water bill long before you see it on a ceiling. BF Plumbing & Drain locates hidden leaks across North Atlanta with electronic leak-detection equipment so the repair is targeted instead of exploratory. We find leaks behind walls, under slabs, in attics, in yards, and inside appliance hookups — and then we fix them.
Accurate location is half the job. The other half is choosing the right repair. We do both — and we'll tell you honestly when a single repair is enough versus when the system is approaching the point that repiping is the better long-term spend.
Signs of a hidden leak
Hidden leaks reveal themselves in indirect ways:
- Water bill is up with no change in usage.
- Water meter dial moves with everything shut off.
- Warm spot on the floor (hot supply leak under slab).
- Sound of running water in walls or ceilings.
- Mildew smell, peeling paint, or stains on ceilings or walls.
- Hardwood cupping, tile cracking, or carpet damp.
Our leak detection process
Finding a leak quickly and without unnecessary damage:
- 1
Confirm there's a leak
Meter test with everything off, isolation between hot and cold systems, narrowing to interior vs. exterior.
- 2
Acoustic and ground microphones
Pressurized supply lines produce a distinctive sound at the leak point that proper equipment can localize through wall, floor or slab.
- 3
Thermal & moisture meters
Where temperature differential exists (hot vs. cold lines), thermal imaging confirms the location. Moisture meters track the leak's spread.
- 4
Pinpoint and mark
We mark the exact location on the surface before any cut. The smaller the access, the smaller the restoration.
- 5
Report and repair plan
You see what we found and what the repair options are. We can perform the repair immediately or schedule it.
What leak detection costs in North Atlanta
Flat-rate detection fee, separate from any repair. Drivers:
- Leak location difficulty — yard vs. slab vs. wall vs. attic.
- Number of accessible test points.
- Whether thermal imaging and tracer gas are required.
- Coverage area — a single room vs. whole-home isolation.
- Same-day vs. scheduled appointment.
- Whether the detection fee is credited toward the repair (it often is).
Leak conditions across North Atlanta
North Atlanta is a patchwork of housing stock and soil conditions, and that drives a lot of plumbing decisions. Subdivisions built in the 1990s and early 2000s across Canton, Woodstock and Holly Springs typically run builder-grade PVC and CPVC that's now reaching end-of-life on fittings and shutoffs. Older homes in Marietta, Roswell and Kennesaw still have cast-iron drains and copper supply that scale up and pinhole. Newer construction in Acworth, Ball Ground and Cumming sits on red clay that shifts seasonally and stresses underground lines.
We work in this market every day, so we know which neighborhoods have shared sewer easements, which water utilities require a permit pull, and which inspectors want to see specific fittings. That local knowledge shortens the job and keeps it code-correct the first time.

Frequently asked questions
How accurate is electronic leak detection?
On supply leaks under pressure, often within inches. Drain leaks are harder because they only run when fixtures are used — we may need to add tracer dye or thermal contrast.
Can you find a leak in a slab?
Yes. Acoustic and thermal tools localize slab leaks reliably. We mark the surface and cut only what the repair requires.
Is leak detection covered by insurance?
Sometimes — many policies cover the detection cost when it's part of a covered claim. We provide documentation that supports the claim.
What if no leak is found?
Sometimes the meter movement is from an irrigation leak, a stuck toilet flapper, or another non-mainline source. We isolate until we either find the leak or rule everything out.
