Frequently Asked Questions

How much does leak repair cost?

Simple leak repairs (faucet, visible pipe) cost $150-$350. Hidden leak detection and repair (behind walls, under slab) costs $350-$1,500+. Emergency leak repair typically adds 50-100% to normal rates.

How do plumbers find hidden leaks?

Professional plumbers use acoustic listening devices, thermal imaging cameras, moisture meters, and video pipe inspection cameras to locate hidden leaks without tearing apart walls or floors.

Does homeowners insurance cover leak repair?

Most policies cover sudden, accidental water damage but not gradual leaks or maintenance issues. The damage caused by the leak is usually covered, but the pipe repair itself may not be. Check your specific policy.
