Slab Leak Repair Through Direct Access in Hickory, NC
When a single leak is found on otherwise healthy pipe, direct access can be the most affordable repair. We cut a small opening in the floor at the marked spot, repair the pipe and pressure test it. Then we patch the concrete and leave the area ready for flooring. Accurate detection keeps that opening as small as it can be.

Video Pipe Inspection for Sewer Leaks in Hickory, NC
Sewer line issues under a slab can also mimic slab leak symptoms. We use high-resolution video cameras to inspect the interior of your drain lines, identifying cracks, blockages or separations. This is vital if the issue isn't a pressurized water line, helping us determine if a sewer line repair is needed instead for your Hickory home.
Electronic Acoustic Leak Detection in Hickory
Our team uses electronic listening devices to pinpoint the precise 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 particularly effective for copper and PEX lines commonly found in Hickory homes.
Acoustic Slab Leak Detection in Hickory
Our technicians rely on highly sensitive acoustic listening devices to pinpoint the exact location of a leak under your slab.

Repiping After Multiple Slab Leaks in Hickory, NC
If your home has had two or more slab leaks, the remaining pipe is likely corroded too. Repiping replaces all supply lines with new PEX or copper run through the walls and attic. It is a bigger project, but it ends the cycle of recurring slab leaks. We can typically complete a full repipe in two to four days.

Frequently Asked Questions About Slab Leak Detection in Hickory
The cost for professional slab leak detection in Hickory, NC typically ranges from $250 to $700, depending on the complexity of the leak and the time required for diagnosis. This initial detection fee is separate from any repair costs, which can vary a lot based on the leak's location and required pipe repair.
Yes, HFN 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 comprehensive warranty on parts and labor, providing you with peace of mind.
HFN Plumbing uses industry-leading brands for our slab leak detection equipment, including but not limited to LeakTronics, FLIR thermal cameras and specialized acoustic sensors. These tools are chosen for their accuracy and dependability in various leak detection scenarios, delivering the best results for your home.
Warm spots on the floor, the sound of running water with fixtures off, a moving water meter and an unexplained jump in your water bill are common signs. Cracked tile, damp carpet and mildew odors also suggest a slab leak. Call us if you notice any of these.
Most slab leak detection services can be completed within 1 to 3 hours, depending on the severity and location of the leak. Our goal is always to be as efficient and non-invasive as possible, providing a quick diagnosis so repair work can begin soon.
Direct repair works well for a single leak on otherwise healthy pipe in an accessible spot. Rerouting is often better under tile or hardwood and avoids future leaks on that line. We help you compare both.
Coastal areas have sandy soil and high water tables, which affect how sewer lines and septic systems function. 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.
Many homeowner insurance policies cover the cost of water damage from a sudden or accidental slab leak, and sometimes the cost of accessing the leak for repair. However, coverage varies a lot, so it's important to check your specific policy with your insurance provider.
