Slab Leak Detection & Repair in Las Vegas
A warm spot on the floor, a jump in your water bill or the sound of running water when everything is off? We find slab leaks without tearing up your home and fix them the right way.
Slab Leaks Are Common in Las Vegas
Most Las Vegas homes are built on concrete slabs with water lines running underneath. Over time, hard water, shifting caliche soil and the constant expansion and contraction from our temperature swings wear pinholes in copper lines where they rub against the concrete. Hot water lines usually go first.
A slab leak can run for weeks before you see it, wasting thousands of gallons and soaking the soil under your home. TPM uses acoustic listening, thermal imaging and line pressure testing to pinpoint the leak, then explains your repair options, from a targeted spot repair to rerouting the line overhead.
Warning signs of a slab leak
- Your water bill suddenly jumpsWith no change in use, this is often the first clue.
- Warm or damp spots on the floorA hot water line leaking under tile or carpet warms the floor above it.
- Sound of running waterHissing or running water when every fixture is off.
- Water meter moving with everything offThe simplest at-home test for a hidden leak.
- Cracks, mildew or damp baseboardsMoisture wicking up through the slab or walls.

Slab Leaks in Las Vegas Homes: Causes and Repair Options
Almost every house in the valley sits on a concrete slab, and in many homes built from the 1980s through the 2000s the water lines run under it. When one of those lines wears through, the leak is hidden under your floor.
Why Las Vegas homes get slab leaks
- Hard water. Our water is full of minerals that wear the inside of copper pipe, especially hot-water lines.
- Pipe rubbing on concrete or gravel. Lines expand and contract every time hot water runs, and over the years they wear through where they touch.
- High water pressure. Pressure above what the home is built for puts extra stress on every joint. If your pressure runs high, a pressure-reducing valve takes that stress off the whole system.
Signs to watch for
A warm spot on the floor, the sound of running water when nothing is on, a water meter that moves with every fixture off, cracks in flooring, or a water bill that jumps for no reason. If you see water coming up through the floor, shut off the main water valve and call us.
Your repair options
- Spot repair: we open the slab right at the leak and fix that section. Best for a single leak in otherwise healthy pipe.
- Reroute: we abandon the leaking line and run a new one through the walls or attic, so no concrete is broken. Often the better choice when the pipe has started failing in more than one place.
- Repipe: for homes with repeat leaks, a whole-home repipe ends the problem for good.
A hot-water slab leak can also make your water heater run nonstop, so we check it too.
Slab Leaks in Las Vegas Homes: Causes and Repair Options
Frequently Asked Questions
How do I know if I have a slab leak?
Common signs are a water bill that jumps for no reason, warm or damp spots on the floor, the sound of running water when everything is off, and a water meter that keeps moving with all fixtures closed.
Is it better to repair or reroute a slab leak?
A spot repair makes sense for a single leak in otherwise healthy pipe. If the copper is thin or you’ve had leaks before, rerouting the line through the walls or attic usually prevents the next one. We’ll show you what we find and recommend the option that fits.
Will you have to jackhammer my floors?
Not always. With accurate detection we can often reroute the line and avoid breaking the slab. When a spot repair is best, we open only a small area at the leak.
Does homeowners insurance cover slab leaks?
Many policies cover the cost of accessing the leak and the resulting water damage, but not the pipe repair itself. Coverage varies, so check your policy. We provide photos and written findings for your claim.
Why are slab leaks so common in Las Vegas?
Hard water, shifting caliche soil and big temperature swings wear on copper lines running under concrete slabs, especially hot water lines.
Does homeowners insurance cover a slab leak?
It depends on your policy. Many policies cover the water damage and the cost of getting to the pipe, but not the pipe itself. We document the leak and the repair with photos so you have what you need for a claim.
Is it better to reroute or repair a slab leak?
A spot repair works well for one leak in healthy pipe. If the pipe is old or has leaked before, rerouting the line through the walls or attic is usually the longer-lasting fix. We show you what we find before you decide.
