Is it urgent? Slab leak signs that need a plumber now

A slab leak is urgent when water is coming up through the floor, the meter will not stop with every fixture off, or a floor spot is warm to the touch; HomeAdvisor and HomeGuide list warm or damp floors, standing water, the sound of running water with fixtures off, pressure drops and water bill spikes as signs. A leak under a slab keeps running until it is found, and LVVWD's bill credit depends on a repair within 60 days of the billing date when you found it. See slab leak repair for every method.

LVVWD will pay up to $2,000 of a slab leak repair

The Las Vegas Valley Water District's Leak Repair Reimbursement Program pays up to 50% of the repair cost, capped at $2,000 per event, for repairs of at least $200. It is for single-family owners with paid invoices, and since July 1, 2025 it can be used once per rolling 365 days. A slab repair at HomeAdvisor's $2,280 national average clears the $200 minimum easily. Separately, the Leak Adjustment reverses the leak part of your bill if use ran at least 50% above baseline; apply within 90 days of the repair.

Repair, line or reroute in a Las Vegas house

Rerouting runs new pipe through walls or the attic and abandons the line under the slab; HomeGuide puts it at $3,900 to $7,500 and Fixr at $4,000 to $15,000. A spot repair through the slab is cheaper, $500 to $3,000 in Fixr's figures, but leaves the rest of the old line in place. Inside the City of Las Vegas, water piping replacement is on the list of permits issued online without plans. The median Las Vegas home was built in 1994, the Census Bureau's 2020 to 2024 American Community Survey shows. Ask what the supply lines are made of and how many leaks the house has had.
