Slab Leak Detection in Florissant
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. FGV 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.

Pinhole Leak Detection in Florissant, 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 use 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. Rapid swings from mild to freezing weather expand and contract pipes and fittings, especially in older homes.
Water Leak Detection Cost Comparison in Florissant, MO
Water leak detection usually 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 pay for the test in saved water.
Irrigation Leak Detection in Florissant
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.
Water Meter Leak Testing in Florissant
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.
Pool Water Leak Detection in Florissant, MO
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 Florissant, MO
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 point to a hidden leak, minimizing the need for extensive wall demolition.

Frequently Asked Questions About Water Leak Detection in Florissant
The cost for water leak detection in Florissant usually ranges from $200 to $600, depending on the complexity and location of the leak. This fee covers the use of professional equipment and the expertise required to pinpoint hidden leaks. Any subsequent repair costs would be quoted separately after the leak is identified.
A rising water bill, the sound of running water, damp spots, mildew odors and a constantly running water heater or softener are common signs. Oddly green patches in the yard can indicate an irrigation or service line leak. Call us if you notice any of these.
For minor water leak repairs that don't involve significant alteration to the plumbing system, a permit is usually not required. However, for extensive pipe replacements, re-piping a section of your home or major slab leak repairs, a plumbing permit from the local building department may be necessary. Our team will explain any permit requirements.
Yes, hard water can contribute to plumbing issues over time. Mineral buildup can speed up corrosion in pipes, especially older copper or galvanized lines, increasing the likelihood of leaks. Regular maintenance can help limit this.
Older homes in Florissant often have galvanized steel pipes, which are prone to corrosion and leaks over time. Polybutylene piping, installed in homes from the 1970s to 1990s, is also well known for premature failure and leaks. While copper and PEX are usually reliable, even they can develop pinhole leaks due to water chemistry or installation issues.
We use professional equipment including acoustic listening devices, thermal imaging cameras, moisture meters, video pipe inspection cameras and sometimes tracer gas detection. These tools allow us to locate leaks non-invasively and with high accuracy.
Yes, we can also detect leaks in residential and commercial irrigation systems. These leaks can waste large amounts of water and damage landscaping. Our methods can pinpoint leaks in underground sprinkler lines and valves.
While leak detection itself typically doesn't require a permit, extensive repairs involving opening walls, altering structural elements or replacing major sections of plumbing often do. FGV Plumbing will take care of all necessary permit applications for any repair work we perform in Florissant.
