Even a small leak wastes thousands of gallons a year and feeds mold behind walls. We use moisture meters, thermal imaging and acoustic listening equipment to pinpoint the leak before opening anything, so repairs are precise and drywall damage is minimal.
Common sources we fix every week: supply lines under sinks, shower valves, toilet seals, water heater connections, pinhole leaks in copper and failed PEX fittings.
