Signs You Might Have a Slab Leak
- A warm or damp spot on your floor, especially over a hot water line
- A water bill that's noticeably higher with no obvious explanation
- The sound of running water when all fixtures are turned off
- Low water pressure throughout the house
- Cracks in flooring or walls that weren't there before
- A musty smell or unexplained mold, especially near the floor
- Your water meter still spinning when nothing is using water
What Is a Slab Leak?
Most East Valley homes are built on a concrete slab foundation, with water supply lines running underneath it. A slab leak happens when one of those lines corrodes, cracks, or develops a pinhole and starts leaking under your home.
Because there’s no basement or crawl space to catch it early, a slab leak can run for weeks before it’s noticed — often not until it’s already caused real damage to flooring, drywall, or the foundation itself.
Why Chandler Homes Are Especially Prone to Slab Leaks
Hard water accelerates pipe corrosion
Nearly every home here sits on a slab
Extreme heat adds stress to pipe joints
How We Find a Slab Leak Without Guessing
We don’t tear up your floor to go looking. Instead, we use professional detection tools to pinpoint the leak’s exact location first:
Using these tools together means we find the leak accurately, which keeps the repair itself as targeted and minimally invasive as possible.
Acoustic detection
listens for the specific sound water makes escaping a pressurized line underground, helping us narrow down the leak's location precisely.
Pressure testing
helps confirm whether a leak exists in the system and gives us information about its general location and severity.
Thermal imaging
can detect temperature differences in the floor caused by a hot water line leaking underneath, which shows up as a warm spot even before it's noticeable to the touch.
Slab Leak Repair Options
Once we’ve located the leak, we’ll walk you through the real options and their tradeoffs:
We’ll explain which option makes the most sense for your specific situation, with real costs for each, rather than defaulting to whichever is easiest for us.
Spot repair
accessing just the leaking section of pipe through the slab, appropriate when the rest of the line is still in good condition.
Re-routing the line
get a plumber who explains what's actually wrong before recommending a fix, with pricing that doesn't change once the work starts.
Repiping
if the leak is a symptom of broader pipe deterioration throughout the home, a full or partial repipe may be the more cost-effective long-term fix rather than repeated spot repairs. See our Whole Home Repiping page for details.

What Slab Leak Repair Really Costs
Slab leak repair costs vary widely depending on the location and severity of the leak, and which repair method actually fits your situation. A targeted spot repair is generally less expensive than re-routing a line through the attic, and both are typically less costly than a full or partial repipe.
This is exactly why accurate detection matters so much before any pricing conversation. We give you a specific, itemized price after we’ve located the leak and understand its full scope, not a rough guess based on symptoms alone.
How a Slab Leak Differs From Other Plumbing Leaks
Not every leak is a slab leak, and it’s worth understanding the difference so you know what you’re actually dealing with. A visible leak under a sink or around a toilet is usually easy to spot and address quickly. A slab leak, by contrast, happens in a water line running underneath your home’s concrete foundation, completely out of sight until symptoms show up elsewhere, like a warm floor spot or a spiking water bill.
This is exactly why slab leaks tend to cause more damage than a typical visible leak before they’re caught. There’s no immediate puddle to alert you, just quiet, ongoing water loss until the signs become noticeable enough to investigate.
Preventing Future Slab Leaks
While you can’t fully eliminate the risk of a slab leak in a hard water region like Chandler, a few things meaningfully reduce it:
Installing a water softener slows the corrosion process that leads to pinhole leaks in the first place, since it removes the minerals responsible for that corrosion.
Addressing water pressure issues matters too. Consistently high water pressure puts extra stress on pipes and fittings throughout your home. If your pressure regularly tests above normal residential levels, a pressure-reducing valve can ease that stress.
For homes over 20 years old with original copper piping, a proactive leak detection check, even without active symptoms, can catch a developing problem before it turns into a full leak and water damage.
What Happens If a Slab Leak Goes Unaddressed
An undetected or ignored slab leak doesn’t resolve itself. Left alone, it typically continues sending water into your foundation and surrounding structure, which can lead to cracked flooring, damaged drywall, mold growth, and in more severe cases, structural concerns with the foundation itself.
Beyond the physical damage, an ongoing leak also means continuously paying for water you’re not actually using, which adds up on your monthly bill for as long as the leak runs undetected.
