Main Service Line Leak Detection in St. Peters, MO
The line from the meter to your house carries full pressure and can leak underground for a long time. Wet soil, soft spots or unusually green patches of yard may be the only clues. We trace the line, listen for the leak and mark it for a targeted repair. Replacing old galvanized or polybutylene service lines is usually recommended.

Pinhole Leak Detection in St. Peters, MO
Pinhole leaks, often found in copper or PEX piping, are small but can cause serious damage over time, especially behind walls or under floors. We employ non-invasive moisture meters to detect elevated humidity levels and thermal cameras to identify cold spots that indicate water. Our plumbers are skilled at tracing these elusive leaks without tearing apart your entire home. Swift action on pinhole leaks prevents extensive drywall damage, mold growth and compromised structural integrity. Hot, humid summers and cold winters give Missouri plumbing a wide range of stress, with big temperature swings in between.
Hidden Wall & Ceiling Leak Detection in St. Peters, MO
Leaks behind walls or in ceilings can cause serious damage before they become visible, leading to stained drywall, peeling paint or a musty odor. These often stem from faulty pipe connections, old galvanized pipes or issues with shower pans and drains. Our technicians use moisture meters and infrared cameras to scan these areas, identifying elevated moisture levels and temperature differences that point to a hidden leak, minimizing the need for extensive wall demolition.
Toilet and Fixture Leak Detection in St. Peters, MO
Toilets are one of the most common sources of wasted water. A worn flapper or a fill valve that never shuts off can leak silently around the clock. We use dye tests to find leaking toilets and check faucets, showers and supply lines for drips. These fixes are typically quick and save water right away.
Water Leak Detection for Insurance Claims in St. Peters
After a water leak, accurate documentation of the leak's source and extent of damage is crucial for insurance claims.

We work quickly to minimize impact on your business, providing rapid diagnosis and repair solutions.
Water Leak Detection Cost Comparison in St. Peters, MO
Water leak detection typically costs $150 to $450 depending on the size of the property. Simple repairs like toilet parts may cost $100 to $300, while service line repairs often run $800 to $3,000. Smart shutoff valves usually cost $500 to $1,500 installed. Stopping even a moderate leak quickly can cover the cost of the test in saved water.

Water Meter Leak Testing in St. Peters
The water meter is the first and easiest leak test. With every fixture and appliance off, a moving leak indicator means water is escaping somewhere. We read the flow rate to estimate how many gallons are being lost. Then we shut off zones one at a time to see which part of the property is losing water.

Frequently Asked Questions About Water Leak Detection in St. Peters
Water leak detection in St. Peters typically costs $150 to $450, depending on property size and how many systems need testing. Repair costs vary based on what we find. We give you a price before we start.
Yes. Repairs we complete carry a written workmanship warranty, and parts include manufacturer warranties. Smart valves also include their own coverage.
Turn off all water inside and outside, then watch your meter for a few minutes. If the leak indicator moves, you have a leak. Adding food coloring to a toilet tank and checking the bowl after 15 minutes will reveal a leaking flapper.
Many water providers offer leak adjustments if you show the leak was repaired. Policies vary by provider. We give you a written repair invoice to back up your request.
Yes, a persistent water leak under your home can cause serious foundation damage. Limestone and rocky ground in the southern part of the state can make digging for sewer lines slower and more costly. Water saturates the soil, leading to expansion and contraction that can shift or crack your foundation, so slab leaks make early detection crucial.
If you suspect a slab leak, the first step is to call a professional like FGV Plumbing immediately. Avoid trying to dig or open up the slab yourself, as this can cause more damage. Turn off your main water supply if the leak is severe, and clear the area for our technicians.
Regular plumbing inspections, especially for older homes, can help identify potential leak points before they become major issues. Consider installing a whole-home leak detection system that alerts you to unusual water flow. Maintaining proper water pressure and addressing minor drips promptly can also significantly reduce the risk of future leaks.
We install smart shutoff valves such as Moen Flo and Phyn, along with wireless leak sensors. These monitor flow and can shut off water when a leak is detected. You get alerts on your phone.
