Water Leak Repair FAQs

Questions about this service

How can I tell where a leak is coming from?
Look for dampness, water stains, or mineral buildup at fixtures, under sinks, and near appliances. Some leaks travel along pipes or inside walls, so the visible drip isn't always the source. A professional assessment can locate the actual origin.
