Leak Detection Las Vegas is a leak detection company in Paradise, NV that locates water leaks in condos and homes, including water from the unit above, before any ceiling or wall is opened.

In a Paradise, NV condo, the clue is often on your ceiling while the source is upstairs.

If it spreads after the unit above runs a shower or dishwasher, a drain line or tub seal is the likely source.
Growth overnight, with nobody upstairs using water, points to a pressurized supply line or fixture valve.
Water follows conduit and ductwork, so a drip from a fixture has usually traveled before it showed.
A wet baseboard with nothing behind it usually means the source is next door or above.
With every tap off, LVVWD says a red or white triangle still moving on the meter may mean a leak.
