Post-Tension Slab Leak Detection in Dunwoody
Many newer homes are built on post-tension slabs that use steel cables under high tension. Cutting into one without care is dangerous and can damage the foundation. We locate the cables with scanning equipment before any repair access is opened. This lets us repair the leak safely or recommend a reroute that avoids the slab entirely.

Electronic Leak Detection in Dunwoody
For hard-to-find leaks, our electronic leak detection equipment sends a signal through your pipes and measures changes that indicate a breach. This technology allows us to locate leaks in various pipe materials, including copper, PEX and PVC, commonly found in Dunwoody homes. It helps prevent exploratory digging, saving you time and money.

Hot Water Slab Leak Detection in Dunwoody
Hot water lines leak under slabs more often than cold lines because heat speeds up corrosion and causes expansion and contraction. Signs include warm spots on the floor, a water heater that runs nonstop and higher gas or electric bills. Thermal imaging shows the heat pattern spreading through tile or concrete. We confirm with a pressure test and acoustic listening before flagging the spot.
Cold Water Slab Leak Detection in Dunwoody, GA
Cold water slab leaks do not create warm spots, so they are harder to see. They often show up as a running water meter, damp carpet, a musty smell or water seeping at baseboards. We isolate the cold side and use acoustic equipment to listen for the leak through the slab. Line tracers map the pipe route so we know exactly where to listen.
Non-Invasive Leak Detection in Dunwoody, GA
Our primary goal is to locate your slab leak with the least amount of disruption possible. We favor non-invasive techniques like acoustic and thermal imaging before considering any intrusive methods. This approach saves your home in Dunwoody, GA from unnecessary damage, preserves your landscaping and lowers the overall cost and time of the repair process.

Electronic Acoustic Leak Detection in Dunwoody
Our team uses electronic listening devices to pinpoint the exact location of a slab leak. These highly sensitive microphones can detect the faint sound of water escaping from a pressurized pipe under your foundation. This non-invasive method helps us avoid unnecessary concrete breaking, saving you time and money on repairs. It's especially effective for copper and PEX lines commonly found in Dunwoody homes.

Frequently Asked Questions About Slab Leak Detection in Dunwoody
Slab leak detection in Dunwoody usually costs $150 to $450. Repairs range from about $800 for a simple reroute to $3,000 or more for direct access under finished floors. We provide a written estimate after locating the leak.
For significant slab leak repairs, especially those involving excavation or extensive re-piping, a plumbing permit from the local building department is often required. HGR Plumbing handles all necessary permitting processes so your repair is compliant with local codes and regulations, protecting your home.
Many policies cover the cost to access the leak and repair resulting water damage, though the pipe itself may not be covered. Coverage varies by insurer. We provide photos and a detailed report for your claim.
Yes, HGR Plumbing stands behind our work. We offer a warranty on our slab leak detection services, standing behind the accuracy of our findings. Any subsequent repair work performed by us also comes with a full warranty on parts and labor, providing you with peace of mind.
Yes. Water leaking under the slab can cause expansive soil to swell or wash away supporting soil. Over time this can lead to cracks and sinking. Fixing leaks quickly protects the foundation.
A water line slab leak involves pressurized fresh water escaping from supply pipes, often resulting in higher water bills, warm spots or the sound of running water. A sewer line slab leak involves wastewater leaking from drain pipes, which typically causes foul odors, slow drains or visible sewage seepage, and is not usually pressurized.
Reroutes and repipes often require a plumbing permit, while small direct repairs may not. Requirements vary by city and county. We take care of permits and inspections when needed.
Homes are a mix of slab, crawlspace, and basement foundations, and crawlspace homes make most supply and drain repairs easier to reach. Hard water can also corrode copper pipes from the inside. Pipes can rub against concrete or gravel as they expand with hot water, and over time these factors cause pinholes and cracks.
