Hidden Leaks Do the Most Damage
A visible leak is a problem. A hidden leak such as behind a wall, under a slab, or beneath your yard, is a problem that quietly gets worse every day you don’t know it’s there. Water finds the path of least resistance and follows it: into wall cavities, under flooring, through concrete, into soil. By the time a hidden leak makes itself obvious, the damage is already done.
Â
We locate and repair hidden water leaks for residential and commercial customers throughout Metro East Illinois, including leaks behind walls, under concrete slabs, beneath yard surfaces, and inside finished spaces where tearing everything open isn’t the right first move. Our goal is to find the leak accurately before recommending how to access and fix it, so the repair is targeted, not exploratory.
Â
Priority Plumbing Services is licensed, bonded, and insured in Illinois (License No. 055-045366). We’re available 24/7 for active leak emergencies throughout Metro East Illinois. Every leak detection and repair job is backed by our 1-year warranty and 100% satisfaction guarantee.
Signs You May Have a Hidden Water Leak
- Water Bill Went Up With No Change in Usage
A water bill that spikes without explanation such as no new irrigation, no houseguests, no change in habits, is one of the clearest signals of a hidden leak. The EPA estimates household leaks waste nearly 10,000 gallons of water per year on average. An active hidden leak runs 24 hours a day and shows up on your bill before you ever see water.Â
Â
Urgency: Call soon — a leak running continuously compounds both the bill and the structural damage over time.
- Sound of Running Water With Everything Off
If you can hear water moving somewhere in your home, or your water meter keeps spinning, with every fixture shut off and no appliances running, you have an active leak somewhere in the system. The sound is often faint and may only be audible in quiet conditions near a wall or floor.Â
Â
Urgency: Call today — shut off your main and call (618) 207-1647. An active hidden leak needs same-day attention.
- Water Stain on a Ceiling or Wall
A water stain that appears or grows on a ceiling below a bathroom, or on an interior wall, usually means a pipe or drain line is leaking inside the wall or floor cavity above. The stain marks where water has traveled, not necessarily where the leak is. Tracing the actual source requires a trained eye.Â
Â
Urgency: Call soon — active ceiling or wall leaks cause mold within 24–48 hours of sustained moisture.
- Warm Spot on the Floor or Tile That Feels Hot
A warm or hot section of concrete floor or tile, especially near a bathroom or utility area, is a classic sign of a slab leak. When a hot water line beneath the slab fails, the heated water transfers through the concrete to the surface above the leak point. This is one of the most actionable slab leak symptoms.Â
Â
Urgency: Call today — slab leaks deteriorate the concrete and soil structure beneath your foundation over time.
- Crack in the Foundation or Floors That's Getting Worse
A foundation crack that continues to grow, or flooring that buckles, cups, or separates in a specific area, can indicate water undermining the soil beneath from a slab or underground pipe leak. Water erodes the compacted soil that supports your foundation and slab, creating voids that eventually cause settling.Â
Â
Urgency: Call today — foundation movement tied to a water leak is a structural concern that warrants immediate assessment.
Types of Leak Detection & Repair We Handle
- Hidden Pipe Leak Detection
Leaks inside walls, above ceilings, and under finished floors located using pressure testing and targeted access, minimizing the area we need to open to find and repair the source. We locate the leak accurately before making any access cuts so we’re opening the right spot, not guessing.
- Slab Leak Detection & Repair
Water and sewer lines running beneath concrete slabs can fail from corrosion, shifting soil, or pipe joint failure. We detect slab leaks using pressure testing and thermal indicators, then repair them through targeted slab access, pipe rerouting above the slab, or, where appropriate, trenchless repair methods. Slab leak detection and repair is one of the more complex leak jobs we handle and one where proper diagnosis before access makes a significant difference in repair cost.
- Water Line Leak Detection
Underground water service line leaks between the street meter and the home, located through pressure testing and, where needed, targeted excavation. We confirm the leak is in the service line before recommending repair or replacement scope.
- Commercial Leak Detection
Hidden leaks in commercial facilities like above ceiling tiles, behind walls, under commercial kitchen floors, cause the same damage as residential leaks and often more disruption. We provide leak detection for commercial properties throughout Metro East Illinois on the same 24/7 emergency basis as residential.
Benefits of Professional Leak Detection
- Find It Right the First Time
Guessing where a hidden leak is, and opening walls, floors, or slabs to look, turns a targeted repair into a demolition project. Professional leak detection locates the source accurately before any access work begins. That means smaller access cuts, less collateral damage, and a repair that addresses the actual problem.
- Stop the Damage Before It Multiplies
Water damages compounds quickly. A small hidden leak left running for weeks causes mold growth, wood rot, concrete deterioration, and soil erosion depending on where it is. The repair cost of a hidden leak discovered early is a fraction of the cost of the same leak discovered after months of damage. Catching it fast is the most important variable.
- Slab Leaks Require Specialized Approach
A slab leak isn’t just a pipe leak that happens to be under concrete, it requires a different repair strategy. Depending on the pipe material, leak location, and extent of damage, the right repair may be targeted slab access, full pipe rerouting above the slab, or trenchless lining. We assess all options and recommend the one that makes the most sense for the specific situation.
- 24/7 Response for Active Leak Emergencies
An active hidden leak, water running behind a wall, pooling under a slab, or audibly flowing through the system, is an emergency. We’re available around the clock for leak emergencies throughout Metro East Illinois. Call or text (618) 207-1647 any time.
- Licensed Work With a Warranty
Leak repairs done without proper diagnosis often address the symptom rather than the source, and the leak returns. We find the actual failure point, repair it correctly, and back the work with our 1-year warranty and 100% satisfaction guarantee. If the leak comes back, we do too.

Leak Detection & Repair Questions
How do I know if I have a slab leak?
The most common signs are a warm or hot spot on the floor above a hot water line, the sound of running water under the floor with everything off, a water bill that’s spiked with no explanation, or cracks in the floor or foundation that are progressing. Any combination of these warrants a call for assessment, slab leaks don’t improve on their own.
Will you have to tear up my floor or walls to find the leak?
Not necessarily, and not before we’ve located it accurately. We use pressure testing to narrow the leak location before recommending any access work. When access is needed, we target it as precisely as possible. A well-located leak typically requires one small access cut, not a wall section.
How much does leak detection cost?
Detection cost depends on the type and location of the suspected leak. We provide a written estimate before any access work begins, including both the detection approach and the repair options once the leak is located. For larger repairs, financing is available through Wisetack.Â
Can a slab leak be repaired without breaking up the whole slab?
Often yes. Depending on the pipe material and leak location, options include targeted slab access at the exact leak point, full pipe rerouting above the slab through walls and ceilings, or trenchless epoxy lining of the failed pipe, which requires minimal or no concrete removal. We assess all three options and recommend the right one for your specific situation.Â
Is a hidden leak covered by homeowner's insurance?
Coverage depends on your policy. Sudden accidental pipe failures are often covered, gradual leaks that develop over time typically are not. We document all our work thoroughly, including the nature of the failure and the repair performed, which you can submit to your insurer. Check your specific policy for water damage and sudden pipe failure coverage.
Do you handle commercial leak detection?
Yes. Hidden leaks in commercial facilities such as above drop ceilings, under commercial kitchen floors, and behind finished walls, are handled on the same licensed, 24/7 emergency basis as residential work. Call (618) 207-1647 anytime for commercial leak emergencies throughout Metro East Illinois.
