Frequently Asked Questions (FAQ)
How do plumbers detect hidden leaks?
We use modern leak detection tools like electronic listening devices, infrared thermography, pressure testing, and gas detection to identify leaks without tearing into your walls or floors.
Are slab leaks common, and how serious are they?
Slab leaks can occur in homes with concrete foundations and are considered serious because they often go unnoticed until major damage has occurred. Early detection is critical.
What does leak detection typically cost?
Leak detection pricing varies depending on the complexity of the issue. However, catching a leak early is almost always far less expensive than repairing water damage.
Can you detect a gas line leak too?
Yes, we’re fully equipped to locate and address gas line leaks as well. If you ever smell gas or suspect a leak, call us immediately—it’s a safety emergency.
Do you offer preventative leak inspections?
Absolutely. Routine inspections can help identify early signs of leaks before they become visible, saving you money and avoiding surprise repairs.
