Water leaks aren’t always obvious. While some appear beneath a sink or around a fixture, others develop behind walls, beneath floors, under concrete slabs, or underground where they can go unnoticed for weeks or months. Even a small leak can waste water, damage building materials, encourage mold growth, and increase your utility bills. Since 1986, Harris has helped New Jersey homeowners locate hidden leaks and recommend the right repair solution before the problem becomes more extensive.

Finding a leak requires more than fixing the visible damage. Our technicians identify the source of the leak, evaluate how it affects your plumbing system, and explain the best repair options for your home. Whether you need emergency leak detection or have noticed signs of a slow plumbing leak, Harris provides professional leak detection services throughout New Jersey.

If you suspect a hidden water leak, schedule professional leak detection with Harris before minor water damage becomes a larger plumbing repair.

Signs You Need Leak Detection

Water leaks aren’t always easy to find. Scheduling leak detection early can help minimize damage and prevent unnecessary repairs.

  • Unexpected increase in your water bill. A hidden leak can waste hundreds of gallons of water without obvious signs.

  • Water stains on walls or ceilings. Discoloration often indicates moisture behind finished surfaces.

  • Musty odors indoors. Persistent damp smells may point to concealed water leaks.

  • Low water pressure. Damaged water lines can reduce pressure throughout your plumbing system.

  • Sounds of running water. Hearing water when fixtures aren’t in use may indicate a hidden plumbing leak.

Our Leak Detection Services

Water leaks can develop anywhere within your home’s plumbing system, and finding the source isn’t always straightforward. Harris provides professional leak detection services to locate hidden leaks, identify the cause of the problem, and recommend the right repair. As part of our comprehensive plumbing services, we help homeowners protect their property from unnecessary water damage and costly repairs.

Hidden Plumbing Leak Detection

Not every plumbing leak is visible. Water lines running behind walls, beneath floors, and through ceilings can develop leaks that remain hidden until noticeable damage appears. Our technicians use professional leak detection methods to locate the source while minimizing unnecessary disruption to your home.

Sink Leak Detection and Repair

Leaks beneath kitchen and bathroom sinks often begin at water lines, shut-off valves, drain assemblies, or plumbing connections. We identify the source of the leak and recommend the appropriate plumbing repair before water damages cabinets, flooring, or surrounding materials.

Slab Leak Detection

Water lines installed beneath concrete foundations can develop leaks due to age, shifting soil, corrosion, or pipe damage. Signs of a slab leak may include warm spots on the floor, unexplained moisture, rising water bills, or the sound of running water. Our technicians locate slab leaks and explain the available repair options.

Emergency Leak Detection

Some leaks require immediate attention to help reduce water damage and protect your home. If you’re experiencing active water intrusion, rapidly increasing water damage, or a major plumbing leak, Harris provides emergency plumbing services to identify the source as quickly as possible.

Water Leak Repair

Once the leak has been located, we’ll explain the condition of the affected plumbing and recommend the most effective repair. Depending on the location and severity of the leak, repairs may involve replacing a damaged pipe, repairing plumbing connections, or addressing worn fixtures and valves.

Why Leak Detection Matters

Locating a leak early can help prevent extensive damage throughout your home. Water that escapes behind walls, beneath flooring, or under a concrete slab can weaken building materials and create conditions for mold growth before visible signs appear.

  • Reduces water waste. Hidden leaks can significantly increase monthly water usage.

  • Helps prevent property damage. Early detection can limit damage to drywall, flooring, cabinetry, and insulation.

  • Protects your plumbing system. Identifying leaks early helps prevent additional wear on connected plumbing components.

  • Supports lower utility bills. Repairing leaks eliminates unnecessary water loss.

  • Provides accurate repairs. Professional leak detection helps ensure repairs address the actual source of the problem.

Why Professional Leak Detection Matters

Finding a leak early can help prevent damage that extends far beyond the plumbing itself. Hidden leaks can waste water, weaken building materials, and create costly repairs if they’re allowed to continue unnoticed.

  • Helps prevent water damage. Locating leaks early can reduce damage to drywall, flooring, cabinets, ceilings, and other parts of your home.

  • Reduces water waste. Even a small plumbing leak can waste a significant amount of water over time and increase your monthly utility bills.

  • Protects your plumbing system. Identifying leaks before they worsen can help prevent additional damage to connected pipes, fittings, and fixtures.

  • Supports healthier indoor conditions. Addressing hidden leaks promptly can help reduce excess moisture that contributes to mold and mildew growth.

  • Provides accurate repairs. Professional leak detection identifies the source of the problem so repairs address the leak itself instead of just the visible symptoms.

Had Harris out to do an assessment on my heater and the technician Chris found a dangerous situation with my heater exchanger that could have slowly put carbon monoxide into my house. I’m grateful that Lee was able to come to the house right away and provide me selections and options. I was able to get a new HVAC system the next day and my family can safely sleep in our home. Everyone from Mathew and Chris M to Lee and the install guys, Louis, Mike and Jhar were amazing and genuinely great people I would have in my home any time.

I was quite satisfied with meeting with Josh, yesterday. While I didn't care for the price, I had to expect things would be that high of a cost. Still, Josh's professional conduct while he was inspecting my tank made it that much easier to say, "yes," and go ahead with the installation request. I am not concerned, at this point, about the job itself. The heater installation, earlier this year was very nicely done and the unit is working great.

The technician first of all was polite, he put his booties on. And I appreciate that because I have hardwood floors original. The technician looked at the situation was able to fix the issue and showed me what can be another possible problem if not addressed.

Requested same day service in the AM and Scott was at the house by 3:00. He was very knowledgeable and professional, making sure that he understood what I wanted regarding the outdoor outlet and the line to it. He worked quickly and left the patio cleaner than when he arrived. I would highly recommend Harris for electrical work.
