Leak Detection and Slab Leak Repair in Las Vegas
Valley homes are built slab on grade, so a supply line that fails under the floor gives you a warm spot, a running meter and a rising bill rather than a visible drip. The Southern Nevada Water Authority runs a Leak Detection Assistance Program offering qualifying single-family customers a voucher worth up to $250 toward diagnosis.
What is included
The work itself
Slab leak detection
Acoustic and thermal location of a failed supply line under a concrete slab.
Slab leak repair or reroute
Spot repair through the slab, or rerouting the line overhead where that is the better long-term answer.
Hidden and wall leak detection
Locating leaks behind walls, under cabinets and in ceilings, and on the service line to the house.
Worth knowing
Before you book
Signs of a slab leak
A warm patch of floor, running-water sound with everything off, an unexplained bill jump, or a meter that turns when nothing is on.
Why copper fails under valley slabs
Homes from the 1960s to 1990s often have copper in or under the slab, and high mineral water plus decades of ground movement opens a pinhole.
The SNWA leak voucher
Apply through SNWA before work begins. One voucher per property per year, used with a participating plumber.

Questions
Leak Detection, answered
How hard is the water in Las Vegas?
Las Vegas Valley Water District publishes valley tap water at roughly 291 parts per million, about 17 grains per gallon, and classifies it as very hard, around two and a half times the national norm. The minerals come from the Colorado River through Lake Mead. It is the single biggest reason water heaters, fixture cartridges and dishwashers wear out faster here than their rated life suggests.
Do I need a permit to replace a water heater in Las Vegas?
Yes. Clark County, the City of Las Vegas and the City of North Las Vegas all require a permit for a replacement as much as for a new installation. Which of the three you deal with depends on your address rather than your mailing city, because a Las Vegas postal address can sit in unincorporated Clark County. We pull the permit and meet the inspector as part of the job.
Are you licensed and insured?
Yes. Monkey Wrench Contractors LLC holds Nevada State Contractors Board licence 0092999 and trades as Monkey Wrench Plumbing. We are a BBB accredited business with an A plus rating, and every technician is background checked. About thirty minutes before your appointment you get a text with the assigned technician's photo, name, licence number and live ETA.
Do you charge for an estimate?
No. The inspection is free and you get a flat-rate price before any work begins, so the number you approve is the number you pay. If the scope changes once something is opened up, we stop and re-quote rather than adding to the invoice at the end.
Are you actually available 24 hours a day?
Yes, dispatch runs 24 hours a day, 7 days a week on (702) 900-5992. If water is actively running and you cannot stop it, shut off your main first and call second, because that one step is the difference between a wet floor and a flooded one.
Is there help with the cost of finding a leak?
There can be. The Southern Nevada Water Authority runs a Leak Detection Assistance Program that gives qualifying single-family customers a voucher worth up to $250 toward leak diagnosis or the first hours of repair. You apply as the account holder before work begins and use a participating plumber, and it is one voucher per property per calendar year.
