Signs of a Slab Leak in Your Home
Slab leaks hide under concrete, so you won't see the break itself. But your home gives off clear distress signals if you know where to look.
Unexplained water bill spike
Usage hasn't changed, but the bill keeps climbing — water is escaping somewhere underground.
Warm spots on the floor
A hot-water line leak transfers heat through the concrete, creating a noticeably warm patch on your tile or wood.
Sound of running water
Faint rushing or hissing beneath the floor when every fixture is off points to a pressurized line break.
Damp or warped flooring
Perpetually wet carpet, buckled hardwood, or damp baseboards — water is seeping upward through the slab. See what slab leaks are and how they're repaired.
Low water pressure
A significant break diverts flow away from your fixtures, causing a sudden pressure drop throughout the house. Read how to fix low water pressure.
Foundation cracks or mold odor
Pooling water shifts soil, causing the slab to settle — new cracks in walls or a persistent musty smell are late-stage warnings.
Quick DIY check: shut off every fixture inside and outside your home, then look at your water meter. If the dial or leak indicator is still moving, water is escaping somewhere in your system.
No Guessing, No Digging
How We Find the Exact Leak
We never jackhammer first. Our technicians use a systematic, non-invasive process to pinpoint the break's exact location and depth before any repair work begins.
Meter test & isolation — we confirm active water loss, then shut off the main valve. If the meter stops, the leak is inside the house; if it keeps moving, it's in the service line.
Acoustic listening — sensitive ground microphones detect the distinct frequency of pressurized water escaping a pipe under concrete.
Thermal imaging & pressure testing — infrared cameras map moisture patterns, and pressure gauges isolate which specific line is compromised.

Our Full Process
Water Leak & Slab Leak Detection
From the first call to the final confirmation, here's every step of how we find and resolve hidden leaks — without unnecessary digging.
Once We Find It
Your Repair Options
The right fix depends on the leak's location, severity, and your home's layout. We explain every option before any work starts.
Pipe Rerouting
We bypass the broken under-slab pipe entirely by running new PEX lines through walls or the attic. The old line is capped and abandoned. Your interior flooring stays untouched.
Slab Penetration
For isolated, accessible breaks, we cut through the concrete to reach and replace the damaged section directly, then repour and restore the surface.
Under-Slab Tunneling
We dig from outside your foundation and tunnel horizontally to the pipe. More labor-intensive, but your indoor flooring is completely undisturbed.

Why It's Urgent
What Happens If You Wait
A slab leak doesn't get better on its own. Constant water escaping under pressure washes away the supporting soil beneath your foundation, leading to settlement, shifting, and structural cracks that spread through walls, doorframes, and the slab itself.
The moisture trapped underneath also creates a breeding ground for mold. By the time you smell it, the damage is usually extensive. Catching it early with professional detection is dramatically cheaper than the structural and mold remediation bill that follows neglect.
Don't Wait — Call NowThe California Factor
Why Slab Leaks Are So Common Here
Roughly 96% of California homes sit on concrete slab foundations, and the High Desert's environment attacks the pipes underneath from every angle.
Electrochemical corrosion
Soil chemistry corrodes the outside of copper pipes while hard, mineral-rich water corrodes the inside — a two-front attack.
Expansive desert soil
Sandy and clay soils swell after monsoon rains and shrink in drought, putting constant stress on rigid underground pipes.
Water chemistry
Municipal chlorine and high alkalinity accelerate pinhole leaks in copper supply lines over time.
Abrasion & vibration
Water pressure causes pipes to vibrate against concrete and gravel, wearing the metal thin until it gives way.

What Drives the Cost
What Affects Leak Detection & Repair Pricing
A quick spot repair and a full reroute are very different scopes. The main factors:
Detection complexity. Standard pressure tests cost less; multi-technology detection on a large home takes longer.
Repair method. A reroute through the attic is very different from breaking and reporing a concrete slab.
Leak location & depth. Under-slab leaks buried deep or under finished flooring add complexity.
Damage extent. If flooring, drywall, or mold remediation is needed, that adds to the scope beyond the pipe itself.

Leak Detection FAQ
How can I tell if I have a slab leak?
Watch for an unexplained spike in your water bill, warm spots on the floor, the sound of running water when fixtures are off, damp or warped flooring, a sudden drop in pressure, or a persistent musty smell. A quick meter check with everything off can confirm active water loss.
How do plumbers detect water leaks under concrete?
Professionals use a combination of acoustic listening devices, thermal imaging cameras, pressure testing, and electromagnetic line tracing to pinpoint the exact break without tearing up the floor. A camera inspection may also be used on drain lines.
Can a slab leak be fixed without digging?
Often, yes. The most common approach is pipe rerouting, which bypasses the broken under-slab pipe by running new PEX lines through walls or the attic. The old line is capped permanently. Trenchless pipe lining is another non-invasive option for certain breaks.
How long can a slab leak go undetected?
Weeks, months, or even years if the leak is small. A slow leak may only show up as a gradually climbing water bill or hairline foundation cracks that develop over time.
Does homeowners insurance cover slab leaks?
It varies. Most policies cover sudden, accidental leaks (like a burst pipe) and may pay for the access cost and resulting water damage restoration. However, slow leaks from wear and tear are usually excluded, and the pipe repair itself is often not covered. Check your specific policy.
Why are slab leaks so common in the High Desert?
Nearly all homes here sit on concrete slabs. The combination of electrochemical pipe corrosion, hard mineral-rich water, expansive desert soil, and water pressure vibration attacks underground pipes from every angle over time.
