Signs of hidden leaks include unexplained increases in your water bill, damp spots on walls or ceilings, reduced water pressure, the sound of running water when no fixtures are in use, or a musty smell. Professional leak detection can confirm and locate the issue.
Plumbers use advanced tools like acoustic listening devices, thermal imaging cameras, and pressure testing equipment to accurately locate leaks without causing unnecessary damage to your property.
The time required depends on the complexity of the plumbing system and the location of the leak. In most cases, a skilled plumber from our team can detect a leak within 1–2 hours.
If you suspect a leak, turn off your water supply to prevent further damage, and contact us today. Avoid attempting DIY fixes, as they could worsen the issue.
The cost varies depending on factors like the size of your property and the complexity of the issue. On average, leak detection services range from $200 to $500. A detailed quote will be provided after an initial assessment.
It depends on your policy. Many insurance plans cover leak detection and repair if the damage was sudden and accidental. However, they may not cover issues caused by neglect or wear and tear. Check with your insurance provider for details.
