SIGNS YOU HAVE A HIDDEN LEAK
Signs You May Have a Hidden Leak in Your Fayetteville Home
Fayetteville’s older homes are particularly vulnerable to hidden leaks. Aging galvanized pipes corrode slowly from the inside and develop pinhole leaks that run for weeks or months before any visible sign appears. By the time a homeowner notices water staining, soft drywall, or mold, the damage is already significant. Catching it early is always the cheaper outcome.

Why Hidden Leaks Are Common in Fayetteville Homes
Galvanized steel water lines
Common in homes built before 1970, galvanized pipes corrode from the inside out over decades. The corrosion eventually eats through the pipe wall, creating pinhole leaks inside walls and under floors that are invisible until the damage is done.
Copper pipe corrosion
Fayetteville homes from the 1970s and 1980s often have copper supply lines. While durable, copper is vulnerable to pinhole leaks in areas with aggressive water chemistry or physical stress from soil movement.
Slab leaks
Homes built on concrete slabs with supply lines running underneath are vulnerable to slab leaks as those lines age and develop pinhole corrosion. The Ozarks freeze-thaw cycle puts additional stress on buried lines each winter.
Aging fixture connections
Supply lines, shutoff valves, and connections behind walls and under sinks in older Fayetteville homes corrode and fail slowly, often leaking into cabinetry or subfloors for months before being noticed.
Poor past repairs
Previous DIY or unlicensed work on older Fayetteville homes often used mismatched materials or improper fittings that fail over time.

SERVICE PROCESS
How We Find Hidden Leaks in Fayetteville
Accurate leak detection requires the right equipment and the right process. We do not open walls or floors until we know exactly where the leak is. Here is how we find it:
01
Pressure testing
We isolate sections of your plumbing system and test pressure to confirm whether a leak is present and narrow down which zone it is in.
02
Acoustic detection
Specialized listening equipment picks up the sound of water escaping under pressure through walls, under slabs, and through soil - pinpointing the leak location without any opening.
03
Thermal imaging
Temperature differences caused by leaking water show clearly on thermal cameras. Particularly effective for slab leaks and leaks inside finished walls where visual inspection is not possible.
04
Moisture meters
We probe walls, floors, and ceilings for elevated moisture levels to narrow the search area before any physical access.
05
Targeted repair
Once we locate the leak precisely, repairs are surgical. No tearing out entire walls or jackhammering full sections of slab when we know exactly where to go.

COMMON QUESTIONS
Water Heater Repair FAQs
How do I know if I have a slab leak in my Fayetteville home?
Warm spots on the floor, the sound of running water when everything is off, unexplained high water bills, and cracks appearing in floors or walls are the most common signs. Fayetteville homes built on concrete slabs with copper or galvanized supply lines are particularly vulnerable as those pipes age.
Can you find a leak without cutting into my walls?
Yes – in most cases. We use acoustic equipment, thermal imaging, and pressure testing to locate leaks precisely before opening anything. When we do need to access a wall or floor, we know exactly where to cut, which keeps repair costs and disruption to a minimum. Accurate leak detection is always cheaper than tearing out walls to search.
My water bill went up but I cannot find a leak - what should I do?
A rising water bill with no visible source is one of the most common signs of a hidden leak. Check your water meter – turn off all fixtures and watch whether the meter is still moving. If it is, you have a leak somewhere. Call us and we will find it.
