Heights Plumbing, Heating & Cooling locates and repairs slab leaks in homes and businesses across North Jersey. A slab leak is a water line failure under or inside a concrete floor, and finding it accurately is most of the job.
We are a family owned, licensed and insured New Jersey plumbing contractor with 56 years of industry experience. We show you what we find, quote it upfront, and give you real options before any concrete gets cut.
Water Under Concrete Never Stays Under Concrete
Slab leaks show up in strange ways: a warm patch on the floor, the sound of running water with everything off, unexplained humidity, or baseboards and flooring that start to lift in one area. Sometimes the first clue is a water bill that jumped.
Around here, slabs show up in additions, converted garages, basement floors and slab-on-grade construction. Copper lines embedded in or beneath concrete can pit and fail over time, and when they do, water spreads sideways through the fill before anything visible appears indoors.
What Our Slab Leak Repair Includes
We confirm the leak at the meter, isolate hot and cold lines, and then use acoustic detection, pressure testing and thermal imaging to fix the location as tightly as possible. Being precise matters here: the difference between a general area and an exact spot is the difference between a small opening and a demolished floor.
Once located, we lay out your options: a targeted spot repair through the slab, or rerouting the affected line above the slab so the failed section is abandoned in place. We explain the tradeoffs in cost, disruption and long-term reliability, then perform the repair, test it, and patch the concrete we opened.
Signs You May Have a Slab Leak
- Warm or hot spot on a concrete floor
- Sound of running water with all fixtures off
- Water bill climbing without a change in use
- Damp carpet or buckling flooring in one area
- Cracks appearing in a slab floor or wall
- Musty odor near a floor-level wall
- Low water pressure throughout the house
- Water seeping up at the base of a wall

Our Slab Leak Repair Process
Verify the leak
We check the meter and pressure test to confirm the loss is real and determine whether it is on the hot or cold side.
Pinpoint the location
Acoustic listening, thermal imaging and line tracing narrow the leak to a specific point under the slab.
Present the options
We explain spot repair versus rerouting, including cost, disruption and how much of the original line stays in service.
Perform the repair
We open only what is necessary, repair or reroute the line, and pressure test the system before closing up.
Patch and confirm
We patch the concrete we opened, clean the work area, and verify at the meter that the loss has stopped.
Slab Leak Repair Options We Offer
Electronic slab leak location
Acoustic and thermal detection that pinpoints the leak so the opening in your floor stays as small as possible.
Spot repair through the slab
Opening a limited section of concrete, replacing the failed pipe, testing, and patching. Best when the rest of the line is sound.
Line rerouting above the slab
Abandoning the failed under-slab run and routing a new line through walls or ceilings. Often the better choice when a line has failed more than once.
Partial repipe
Replacing the affected hot or cold distribution where multiple failures suggest the original piping is at the end of its life.
Post-repair verification
Meter and pressure testing after the work so you have proof the leak is actually gone.

Slab Leaks FAQs
How do you find a leak under concrete?
We isolate hot and cold lines, then use acoustic listening equipment and thermal imaging to trace the sound and heat signature of escaping water to a specific point before opening the floor.
Is it better to repair the pipe or reroute it?
A spot repair is less disruptive and makes sense for a first failure on otherwise good piping. If a line has leaked more than once, rerouting above the slab usually ends the problem for good.
Will my homeowners insurance cover it?
Coverage varies widely by policy. Many policies treat resulting water damage differently from the plumbing repair itself. We provide documentation of what we found and what we did so you can submit it to your carrier.
Do slab leaks happen in North Jersey homes?
Yes. They are less common here than in slab-on-grade regions, but we see them in additions, converted garages, radiant floors and basement slabs where supply lines run under concrete.
How long does the repair take?
A straightforward spot repair is often a one-day job once the leak is located. Rerouting a line or a partial repipe takes longer depending on access and finishes.
