SLAB LEAK REPAIR
Slab Leak Repair in Las Vegas
Suspect a slab leak? Our licensed plumbers use advanced electronic detection to pinpoint leaks beneath your foundation — without tearing up your home. Fast, accurate, and minimally invasive repair.
What Is a Slab Leak?
A slab leak is a water leak in the copper pipes running beneath your home's concrete foundation. Because the pipes are buried under 4–6 inches of concrete, these leaks are invisible until the damage becomes severe.
Why Slab Leaks Are Common in Las Vegas
Las Vegas has one of the highest rates of slab leaks in the country. The combination of extremely hard water (291 ppm) and copper pipes creates a perfect storm for corrosion. Hard water deposits thin the pipe walls from the inside, while the alkaline desert soil attacks them from the outside. Homes built between 1970 and 2000 are especially vulnerable.
5 Warning Signs of a Slab Leak
The sooner you catch a slab leak, the less damage it causes. Watch for these telltale signs.
Hot Spots on the Floor
If you feel a warm area on your floor — especially on tile or concrete — a hot water line beneath the slab is likely leaking. The heat radiates up through the concrete as hot water saturates the surrounding soil.
Unexplained High Water Bills
A sudden spike in your water bill without increased usage is one of the most reliable indicators. Even a small slab leak can waste 10,000+ gallons per month, adding $100–$300 to your bill.
Sound of Running Water
If you hear water running when all faucets and appliances are off, water is escaping somewhere in your system. Press your ear to the floor — if the sound is louder, it may be a slab leak directly below.
Foundation Cracks
Water eroding soil beneath your foundation can cause settling and cracking. Look for new cracks in your foundation walls, drywall, or flooring. Even small hairline cracks can indicate movement from a slab leak.
Mold, Mildew, or Musty Smell
Persistent moisture from a slab leak creates ideal conditions for mold growth beneath flooring and in walls. If you smell mold or see discoloration on baseboards without an obvious water source, investigate for a slab leak.
Our Detection Process
We use advanced technology to find the exact location of your slab leak without unnecessary demolition.
Electronic Leak Detection
We use acoustic listening equipment that amplifies the sound of escaping water through concrete. Our technicians can pinpoint the leak location within inches, even through 6 inches of concrete slab. This non-invasive method means we don't have to tear up your floor to find the problem.
Camera Inspection
For drain line slab leaks, we use high-definition sewer cameras to visually inspect the pipe interior. This shows us the exact type and location of damage — whether it's corrosion, a crack, a joint failure, or root intrusion — so we can recommend the most effective repair method.
Slab Leak Repair Methods
We offer multiple repair options and recommend the most cost-effective solution for your specific situation.
Epoxy Pipe Lining
Least invasive — We coat the inside of the existing pipe with epoxy resin that hardens into a new pipe within the old one. No digging required. Best for small leaks and pipes with minor corrosion. Adds 50+ years of life to the pipe.
Cost: $2,000 – $4,000
Pipe Reroute
Most common — We abandon the leaking pipe and run a new line through the attic, walls, or along the exterior of your home, bypassing the slab entirely. Eliminates future slab leak risk on that line. Minimal floor disruption.
Cost: $2,500 – $5,000
Direct Access (Jackhammer)
When necessary — We cut through the concrete slab to access and replace the damaged pipe section. Used when the leak is in a location that can't be rerouted or lined. We restore the concrete after the repair.
Cost: $1,500 – $3,500
If we detect multiple leaks or widespread corrosion, a whole-house repipe may be the most economical long-term solution.
Slab Leak FAQs
How do I know if I have a slab leak?
The most common signs are unexplained high water bills, the sound of running water when everything is off, hot spots on your floor, damp carpet or warped flooring, foundation cracks, and mold or musty odors. You can do a simple test: turn off all water in your home and check your water meter. If it's still moving, you have a leak somewhere.
Does homeowner's insurance cover slab leak repair?
Most homeowner's insurance policies cover the damage caused by a slab leak (water damage, mold remediation, flooring replacement) but do not cover the plumbing repair itself. We recommend filing a claim for the water damage and contacting your insurance agent before repairs begin. We can provide documentation to support your claim.
Why are slab leaks so common in Las Vegas?
Three factors combine to make Las Vegas a slab leak hotspot: (1) extremely hard water at 291 ppm corrodes copper pipes from the inside, (2) the alkaline, mineral-rich desert soil attacks pipes from the outside, and (3) most homes built from the 1970s through 2000s used copper pipes under the slab, which are vulnerable to this dual corrosion. Homes over 20 years old are at highest risk.
How long does slab leak detection take?
Electronic slab leak detection typically takes 1–2 hours. Our technicians systematically test your water lines using acoustic equipment and thermal imaging to pinpoint the exact leak location. We can usually identify the leak and provide repair options the same day.
Should I repipe my entire house if I have one slab leak?
Not necessarily, but it depends on the overall condition of your pipes. If we detect widespread corrosion during inspection, or if you've had multiple slab leaks, a whole-house repipe is usually more cost-effective than repairing individual leaks. We'll give you an honest assessment. Learn about repiping.
Can a slab leak damage my foundation?
Yes, over time a slab leak erodes the soil beneath your foundation, causing the concrete to settle unevenly. This can lead to foundation cracks, door and window misalignment, and structural damage. The desert soil in Las Vegas is particularly susceptible to erosion when saturated. Early detection and repair is critical to preventing structural damage.
Suspect a Slab Leak? Don't Wait.
Every day a slab leak goes unrepaired, it causes more damage to your foundation, flooring, and wallet. We'll find it fast and fix it right.
