Main Service Line Leak Detection in Mandeville, LA
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.

Slab Leak Detection in Mandeville
Slab leaks are common in homes on shifting soil and moving foundations. These leaks occur in pipes beneath your concrete slab, often indicated by warm spots on the floor, sudden spikes in your water bill or the sound of running water when all fixtures are off. Beau's Plumbing uses dedicated acoustic listening devices and thermal imaging cameras to precisely locate these hidden leaks without destructive guesswork. Early detection is essential to preventing major foundation damage.
Water Heater and Softener Leak Detection in Mandeville
Water heaters and softeners can leak at fittings, valves and drain lines. A softener stuck in regeneration can send water down the drain continuously, and a dripping relief valve on a water heater wastes water too. We check these units carefully and repair or replace failed parts. That often explains a mystery bill in homes that have water softeners.
Irrigation Leak Detection in Mandeville
Drip and sprinkler systems run underground across yards and often account for hidden water loss. Cracked tubing, broken emitters and stuck valves can waste huge amounts of water. We isolate the irrigation system, test each zone and trace leaking lines. Repairs restore proper watering for your landscape.
Pool Water Leak Detection in Mandeville, LA
Pools lose a lot of water to evaporation in summer heat, so a leak can hide behind normal loss. We use a bucket test to compare evaporation with actual water loss. Then we pressure test pool plumbing and dye test fittings, lights and skimmers. Finding the leak safeguards the pool and the soil around it.
Hidden Wall & Ceiling Leak Detection in Mandeville, LA
Leaks behind walls or in ceilings can cause significant 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 indicate a hidden leak, minimizing the need for extensive wall demolition.
Toilet and Fixture Leak Detection in Mandeville, LA
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 usually quick and save water right away.

Pinhole Leak Detection in Mandeville, LA
Pinhole leaks, often found in copper or PEX piping, are small but can cause significant 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 adept 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. Humid air causes sweating pipes and toilet tanks, and that moisture can damage subfloors and framing if leaks go unnoticed.

Water leak detection is essential for homes in Mandeville, LA, because leaks can saturate the soil under a foundation and hidden moisture feeds mold growth inside walls and floors.

Frequently Asked Questions About Water Leak Detection in Mandeville
Water leak detection in Mandeville usually 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 begin.
Common signs of a hidden water leak include unusually high water bills, damp spots on walls or floors, the sound of running water when no fixtures are in use, a musty odor or visible mold growth. Also, a sudden drop in water pressure or changes in your water meter reading when no water is being used can indicate a problem.
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 smartphone.
Small repairs typically do not require a permit, but service line replacements and repipes often do. Requirements vary by city and county. We take care of any permits needed.
Leaks in the main water line from the street to your home are usually your responsibility to repair. Our leak detection services cover these lines, and we can pinpoint the leak's exact location. We will then provide options for repair or replacement, so your main water supply is restored efficiently and up to local Mandeville codes.
Yes. A softener stuck in regeneration or with a faulty valve can send water down the drain continuously. We check softeners as part of our leak detection.
Yes, a persistent water leak under your home can cause significant foundation damage. Low-lying areas have a high water table and settling ground, which can cause sewer lines to sag, crack, or separate over time. Water saturates the soil, leading to expansion and contraction that can shift or crack your foundation, so slab leaks make prompt detection crucial.
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 show a leaking flapper.
