Water leaks are one of the most destructive problems a Las Vegas homeowner can face. A hidden leak under your slab foundation, inside a wall, or along a buried water line can run for weeks or months before you notice — quietly causing structural damage, mold growth, and sky-high water bills. In a city where the average home sits on a concrete slab over desert soil, leak detection requires specialized equipment and expertise.
The Cooling Company uses advanced leak detection technology to pinpoint the exact location of hidden leaks with minimal disruption to your property. Our licensed plumbers then present clear repair options with upfront pricing so you can make an informed decision.
Types of Leaks We Detect
Slab Leaks
Slab leaks occur when water or sewer pipes running beneath your concrete foundation develop cracks, pinhole leaks, or joint failures. These are among the most common and most damaging leak types in Las Vegas homes. The combination of reactive desert soil, mineral-heavy water, and copper pipe corrosion makes slab leaks a recurring problem in the Las Vegas Valley. Left undetected, slab leaks can undermine your foundation, cause floors to buckle, and lead to mold growth in your home.
Water Line Leaks
The water supply line connecting the city main to your home runs underground and can develop leaks from soil shifting, corrosion, tree root intrusion, or age-related deterioration. Signs include unexplained wet spots in your yard, dropping water pressure, or a water meter that spins when all fixtures are off.
Behind-Wall Leaks
Pipes running through walls can develop leaks at joints, bends, or where copper has corroded. These leaks often go unnoticed until you see water stains, bubbling paint, warped baseboards, or detect a musty smell. Behind-wall leaks are especially dangerous because they promote mold growth in enclosed spaces.
Irrigation Line Leaks
Las Vegas landscaping typically relies on drip irrigation and sprinkler systems. Underground irrigation lines can crack from soil movement, sun exposure at connection points, or damage during landscaping work. With Las Vegas water rates among the highest in the West, even a small irrigation leak adds up fast.
Pool and Spa Line Leaks
Underground pool plumbing can develop leaks at joints, fittings, or along pipe runs. If your pool is losing more than a quarter inch of water per day (beyond normal evaporation), a leak in the supply or return lines is likely.
Sewer Line Leaks
Sewer lines beneath and around your home can crack, separate at joints, or collapse from age, soil shifting, or root intrusion. Sewer leaks create odor problems, yard contamination, and can attract pests. Camera inspection is the most effective method for locating sewer line damage.
Our Leak Detection Methods
We use multiple detection technologies to locate leaks precisely, reducing the need for exploratory demolition and minimizing damage to your home:
| Detection Method | How It Works | Best For |
|---|---|---|
| Electronic leak detection | Sensitive electronic sensors detect the sound frequency of pressurized water escaping from a pipe, even through concrete and soil | Slab leaks, water line leaks |
| Acoustic detection | Amplified listening devices isolate the sound of water movement within pipes and at leak points | Pressurized water lines, behind-wall leaks |
| Thermal imaging | Infrared cameras detect temperature differences caused by water evaporation or pooling behind walls and under floors | Behind-wall leaks, under-floor leaks, slab leaks |
| Camera inspection | Waterproof cameras inserted into drain and sewer lines provide direct visual confirmation of cracks, separations, and blockages | Sewer line leaks, drain line damage |
| Pressure testing | Pipes are isolated and pressurized to determine if the system holds pressure, confirming the presence and general area of a leak | Whole-house leak confirmation, irrigation systems |
| Tracer gas detection | A safe, non-toxic gas is introduced into the pipe system and detected at the surface where it escapes through the leak point | Difficult-to-locate slab leaks, pool lines |
Why Las Vegas Homes Are Prone to Leaks
Las Vegas has several environmental factors that make water leaks more common and more destructive than in many other cities:
- Reactive desert soil — the clay-heavy, expansite soil in the Las Vegas Valley expands when wet and contracts when dry, shifting around pipes and foundations. This constant movement stresses pipe joints and creates the conditions for slab leaks.
- Hard water and mineral deposits — Las Vegas water is some of the hardest in the country (over 16 grains per gallon). Calcium and mineral buildup corrodes copper pipes from the inside, especially in hot water lines, creating pinhole leaks over time.
- Copper pipe corrosion — most Las Vegas homes built between 1970 and 2005 used copper supply pipes. The combination of hard water, hot soil temperatures, and electrolysis accelerates copper degradation. Homes in this age range are at highest risk for slab leaks.
- Extreme temperature swings — ground temperatures beneath slabs fluctuate significantly between summer highs and winter lows, causing thermal expansion and contraction in buried pipes.
- Slab-on-grade construction — the vast majority of Las Vegas homes are built directly on concrete slabs, with water and sewer pipes embedded in or beneath the slab. This makes leaks harder to detect and access.
- Aging infrastructure — many neighborhoods in Las Vegas, Henderson, and North Las Vegas have plumbing systems that are 25 to 50 years old, well past the expected lifespan of original copper piping.
Signs You May Have a Hidden Leak
Watch for these warning signs that indicate a possible water leak in your Las Vegas home:
- Unexplained increase in your water bill — a sudden spike or steady upward trend without changes in usage
- Water meter running when all fixtures are off — turn off every tap, toilet, and appliance, then check your meter. If it is still moving, you have a leak.
- Warm spots on the floor — hot water slab leaks create noticeable warm areas on tile or hardwood floors
- Sound of running water when nothing is on — a faint hissing or rushing sound coming from walls or floors
- Cracks in foundation or walls — water undermining the soil beneath your slab can cause foundation settlement and visible cracking
- Musty or moldy smell — persistent dampness behind walls or under floors creates conditions for mold
- Discolored or warped flooring — water seeping up through the slab can warp hardwood, lift tile, or stain carpet
- Damp or soft spots in your yard — areas that are always wet or unusually green may indicate an underground water line leak
- Low water pressure — a leak in your supply line reduces the pressure available to your fixtures
- Pool losing water faster than evaporation — Las Vegas pools typically lose about a quarter inch per day to evaporation in summer. Anything more suggests a leak.
Leak Detection Cost in Las Vegas
Leak detection costs depend on the type of leak, accessibility, and the methods required to locate it:
| Service | Typical Cost Range | Includes |
|---|---|---|
| Standard leak detection (electronic/acoustic) | $150 - $400 | Locate leak, identify pipe type and depth |
| Thermal imaging inspection | $200 - $500 | Full thermal scan of affected area |
| Sewer camera inspection | $150 - $350 | Video inspection with location marking |
| Slab leak detection | $200 - $600 | Electronic and acoustic pinpointing beneath slab |
| Whole-home leak assessment | $300 - $800 | Pressure test, electronic scan, thermal imaging |
Detection cost is separate from repair cost. We provide a complete repair estimate with upfront pricing after locating the leak. Financing is available for major repairs on qualified purchases.
What Happens After We Find the Leak
Once we pinpoint the leak location, we present your repair options clearly:
- Spot repair — access the leak point, repair or replace the damaged section of pipe. Best for isolated leaks in newer plumbing systems.
- Pipe reroute — run a new pipe section around the slab (through the attic or along the exterior wall) to bypass the damaged area. Common for slab leaks where the remaining under-slab pipe is also deteriorating.
- Full repipe — replace all supply piping with modern PEX or copper. Recommended when your home has multiple leak points or aging copper throughout. See our plumbing services page for repipe details.
- Epoxy lining — for certain pipe types and conditions, interior epoxy coating can seal small leaks and extend pipe life without excavation.
We explain the pros, cons, and cost of each option so you can choose the approach that fits your home and budget.

Frequently Asked Questions
How do I know if I have a slab leak?
Common signs of a slab leak include warm spots on the floor, the sound of running water when all fixtures are off, unexplained increases in your water bill, cracks in your foundation or walls, and a water meter that keeps running with everything turned off. If you notice any of these signs, call (702) 567-0707 for a professional detection.
Do you have to break up my floor to find a leak?
No. Our electronic, acoustic, and thermal detection methods locate leaks through concrete without demolition. We pinpoint the exact location before any access work begins, which means we only open the minimum area necessary to reach the pipe for repair.
How much does leak detection cost in Las Vegas?
Standard leak detection ranges from $150 to $600 depending on the type of leak and methods required. Slab leak detection typically costs $200 to $600. A whole-home assessment with multiple detection methods runs $300 to $800. Repair costs are separate and presented with upfront pricing after the leak is located.
Why are slab leaks so common in Las Vegas?
Las Vegas has a combination of factors that promote slab leaks: extremely hard water that corrodes copper pipes from the inside, reactive desert soil that shifts and stresses pipe joints, slab-on-grade construction with pipes embedded beneath concrete, and temperature extremes that cause expansion and contraction. Homes built between 1970 and 2005 with original copper plumbing are at the highest risk.
Should I repair a slab leak or reroute the pipe?
It depends on the age and condition of your plumbing. If you have a single leak in otherwise healthy piping, a spot repair is cost-effective. If your home has older copper pipes and this is not the first leak, a reroute or repipe is often the better long-term investment because additional leaks are likely. We present both options with clear pricing so you can decide.
Does homeowners insurance cover slab leak detection and repair?
Most homeowners insurance policies cover the resulting damage from a sudden slab leak (water damage to flooring, drywall, etc.) but do not cover the cost of the plumbing repair itself. Coverage varies by policy, so check with your insurance provider. We can provide documentation of the leak and repair for your insurance claim.
How long does leak detection take?
Most leak detection appointments take 1 to 3 hours depending on the complexity and number of potential leak locations. A straightforward slab leak detection with electronic equipment can be completed in about an hour. Whole-home assessments involving multiple detection methods may take 2 to 3 hours.
Can you detect pool leaks?
Yes. We use pressure testing and tracer gas methods to locate leaks in underground pool supply and return lines. If your pool is losing more than a quarter inch of water per day beyond normal evaporation, a pressure test can confirm whether the plumbing or the shell is leaking.
