Find It Before It Finds Your Foundation
Leak Detection in Alpharetta, GA
A hidden leak can run for months inside a wall, under a slab, or beneath the yard before anything visible happens. By the time drywall stains or the floor feels warm underfoot, the repair is bigger than it needed to be. Licensed technicians at bluefrog Plumbing + Drain of Alpharetta locate water and gas leaks precisely, so the fix stays small and your home stays intact.

What Is Leak Detection?
Leak detection is the use of specialized equipment to find hidden leaks in a plumbing system without opening walls or breaking concrete to go looking. Our Georgia-licensed technicians in Alpharetta start by confirming a leak actually exists — checking water pressure and watching the meter with every fixture closed — before locating it. Confirming first and locating second is what keeps this from turning into exploratory demolition.
What Every Homeowner Should Know About Hidden Leaks
Precise Diagnosis, Then a Plan.
Methods We Use
Our technicians locate leaks with:
- Acoustic listening equipment that hears water escaping a pressurized line
- Electronic amplification to narrow the location down to a specific point
- Infrared thermal imaging to read temperature differences behind walls and under floors
- Video camera inspection for sewer and drain lines
We walk you through what we found and show you the evidence before quoting anything. Pricing is provided upfront, in writing.
Types of Leaks We Handle
Supply line and fixture leaks, water heater connections, slab leaks under concrete foundations, underground breaks in main water lines and irrigation systems, and gas line leaks located with equipment built specifically for safe gas inspection. Slab-on-grade construction is common throughout Alpharetta, Roswell, and Cumming, and a slab leak is one of the few plumbing problems that genuinely requires this equipment — there's no reliable way to find one by looking.
Why Early Detection Pays
A leak losing a steady drip wastes hundreds of gallons a month while it works on your subfloor, framing, and foundation. Standing moisture inside a wall cavity grows mold, which turns a plumbing repair into a remediation project. Finding a leak in week two instead of month six is usually the difference between a spot repair and a claim.
Common Signs of a Hidden Leak
- A water bill up 10% or more with no change in usage
- Damp patches on walls, ceilings, or baseboards
- Musty odor or visible mold
- Water running when every fixture is off
- Warm spots on the floor, a classic slab leak sign
- New cracks in the foundation or driveway
- A patch of grass greener than the rest of the yard
- A water meter that keeps moving with the main shut off

Find Hidden Leaks Before They Cause Damage
Slab Leak Detection
A leak under a concrete slab shows itself as a warm floor, an unexplained bill, or the sound of running water with nothing turned on. We locate it acoustically and with thermal imaging so the repair opens the smallest possible area of your floor, rather than chasing it across the room.
Underground & Main Line Leaks
Between your meter and your home, a break can run for weeks without surfacing — North Georgia clay absorbs and moves the water instead of pushing it up. We pressure test the line and pinpoint the break before any digging starts.
Gas Leak Detection
A sulfur or rotten-egg smell, hissing near an appliance connection, or an unexplained jump in gas usage all warrant an immediate call. We locate gas leaks with equipment made for the job. If you smell gas strongly, leave the home first and call from outside.

Questions that Alpharetta homeowners ask about leak detection
Leak Detection FAQsThe clearest signs are a warm spot on the floor, the sound of running water with every fixture turned off, an unexplained increase in your water bill, and new cracks in the floor or foundation. You may also notice damp carpet or flooring with no source above it, or a water meter that keeps moving after the main is shut off. Any of these warrants professional leak detection promptly.
Cost depends on property size, how accessible the plumbing is, and how complex the leak is to isolate. A leak in an accessible supply line is straightforward; a slab leak or an underground main line break requires more equipment and time. bluefrog Plumbing + Drain of Alpharetta provides upfront pricing before detection begins, and we confirm a leak actually exists before starting so you aren't paying to search for a problem that isn't there.
The most common causes are abrasion where a pipe rubs against concrete or gravel as it expands and contracts, corrosion of copper lines from soil chemistry or water chemistry, poor installation that left a line under stress, and shifting soil putting pressure on the pipe. North Georgia clay expands when wet and contracts when dry, and that seasonal movement stresses lines running beneath a slab.
A slab leak is a leak in a water line running beneath or within the concrete foundation slab of a home. Because the pipe is encased in or buried under concrete, the water has nowhere obvious to go — it saturates the ground under the slab or works up through the floor. Slab-on-grade construction is common throughout Alpharetta, Roswell, and Cumming, which makes slab leaks a regular occurrence in this area.
It depends on the policy and the cause. Many homeowners policies cover the damage a sudden slab leak causes — flooring, drywall, and the cost of accessing the pipe — while excluding the repair of the pipe itself. Gradual leaks and wear-related failures are commonly excluded. Documentation matters for a claim, so we provide written findings and photos from the detection process that you can submit to your carrier.
