Frequently Asked Questions About Leak Detection in Ballwin
Leak detection in Ballwin usually costs $150 to $450 for a typical home, depending on the size of the system and the number of areas tested. Pool leak detection runs about $250 to $500. We tell you the price before we begin.
While you can check for obvious leaks, hidden leaks often require professional equipment like acoustic sensors, thermal cameras or tracer gas to locate accurately. A professional plumber will pinpoint the source without unnecessary damage to your home, saving you time and money.
FGV Plumbing stands by the quality of our work. We offer warranties on our leak detection services and any subsequent repairs. Specific warranty details will be provided with your service agreement.
Most standard leak detection services can be completed within 1 to 3 hours. More complex cases, such as multiple leaks or hard-to-access areas like under a slab, might take longer to precisely pinpoint.
If you suspect a gas leak, right away evacuate everyone from the property, do not use any electrical devices, and call your gas utility company and FGV Plumbing from a safe location. Gas leaks are very dangerous and require immediate professional attention.
Water in much of Missouri is moderately hard to hard, so scale gradually builds in water heaters, faucets and appliances. Hard or aggressive water can cause pinhole corrosion in copper pipes over time. Slab foundations on shifting soils also put stress on pipes underneath the house, and high water pressure in some areas adds more strain.
Older homes may have galvanized steel or polybutylene pipes, both known for higher leak rates due to corrosion or material degradation. Copper pipes can develop pinhole leaks over time, while PVC and PEX are usually more reliable but can still leak at fittings or due to installation errors.
While you can check for obvious leaks like dripping faucets, hidden leaks require professional tools and expertise. DIY attempts can often misdiagnose the problem or cause further damage, especially with slab or gas leaks.
