Water leaks, even small ones, can lead to significant damage and costly repairs if left unaddressed. Often, leaks are hidden behind walls, under floors, or underground, making them difficult to spot without professional help. Knowing the common signs can help you act quickly.
Common Indicators of a Hidden Leak:
- Unexplained Increase in Water Bill: A sudden spike in your water usage without a change in habits is a strong indicator of a leak.
- Sound of Running Water: If you hear water running when no fixtures are in use, it could be a hidden leak in your pipes.
- Damp Spots or Discoloration: Wet spots, stains, or peeling paint on walls, ceilings, or floors can indicate a leak behind the surface.
- Musty Odors: A persistent musty or mildewy smell, especially in basements or near walls, can signal hidden moisture from a leak.
- Low Water Pressure: A sudden drop in water pressure throughout your home might indicate a leak in your main water line.
- Pest Infestations: Constant moisture from leaks can attract pests like cockroaches and rodents.
Types of Water Leaks We Specialize In
Harris Plumbing Inc. has the expertise and technology to detect and repair all common types of residential water leaks, minimizing damage and restoring your plumbing system.
Hidden Leaks Behind Walls & Ceilings
These leaks are often silent and destructive, slowly damaging drywall, insulation, and electrical systems. Our non-invasive methods can find them without tearing apart your home.
Slab Leaks & Foundation Leaks
Leaks under concrete slabs or foundations can be particularly challenging and lead to significant structural damage. We use specialized equipment to detect these elusive leaks.
Underground Water Line Leaks
Leaks in your main water line, from the street to your home, can cause significant water loss and property damage. We accurately locate and repair these underground issues.
Burst Pipe Repair & Prevention
Whether due to freezing temperatures, corrosion, or age, a burst pipe requires immediate attention. We offer rapid emergency response for burst pipe repair and can advise on prevention.
Our Advanced Water Leak Detection Process

At Harris Plumbing, we follow a systematic and non-invasive approach to identify the source of your water leak:
- Initial Assessment: Our licensed plumber will conduct a thorough visual inspection and discuss any symptoms you've noticed.
- Acoustic Listening Devices: We use sensitive microphones to listen for the sound of water escaping from pipes, even behind walls or underground.
- Thermal Imaging Cameras: These cameras detect temperature changes caused by water leaks, helping us identify hidden moisture.
- Video Pipe Inspection: For drain or sewer line leaks, we use flexible cameras to visually inspect the inside of your pipes.
- Precise Pinpointing & Repair: Once the leak is located, we provide clear recommendations and proceed with the most efficient and least disruptive repair method.
The Importance of Prompt Water Leak Detection & Repair
Addressing a water leak quickly is crucial to prevent minor issues from escalating into major, costly problems. Prompt detection and repair can:
- Prevent Structural Damage: Water can weaken foundations, rot wood, and damage drywall, leading to expensive structural repairs.
- Avoid Mold and Mildew Growth: Constant moisture creates an ideal environment for mold, which can cause health issues and further property damage.
- Conserve Water & Reduce Bills: Even a small leak can waste thousands of gallons of water annually, leading to unnecessarily high utility bills.
- Protect Your Valuables: Leaks can damage furniture, electronics, cherished possessions, and other contents of your home.
