Decades Of Stopping Leaks In Their Tracks
A rising water bill, spreading ceiling stain, or sound of running water when every fixture is off can indicate a hidden leak. Some leaks are easy to spot. Others develop inside walls, beneath floors, in crawl spaces, or under a slab where water can cause damage before the source becomes visible.
CB Smith Plumbing has provided leak detection and repair in Spartanburg since 1982. Our licensed plumbers locate the source as precisely as possible before recommending a repair. When plumbing repairs are needed, our team can handle those as well.
Finding Hidden Plumbing Leaks
Water does not always appear near the source of a leak. It can travel along pipes, framing, or other materials before creating a visible stain or damp area somewhere else. Finding the source first can help limit unnecessary openings in walls or floors.
Signs of a Hidden Water Leak
Hidden plumbing leaks can produce several warning signs, including:
- A water bill that rises without a clear change in household use
- Running or hissing sounds when fixtures are off
- Stains, bubbling paint, or discoloration on walls or ceilings
- Warm or damp areas on the floor
- Musty odors from a crawl space, cabinet, or other enclosed area
- Unexplained changes in water pressure
- Damp areas that return after drying
These symptoms do not always confirm a plumbing leak, but they are worth investigating when there is no obvious explanation.
Supply Line Leaks vs. Drain Leaks
Supply and drain leaks can behave differently. Supply lines remain under pressure, so a leak may continue even when no fixtures are being used. Depending on its location and severity, it may also cause unexplained water usage.
Drain leaks occur when water moves through the drainage system. A stain or damp area that appears after a shower, dishwasher cycle, or other fixture use may point to a drain-side problem.
Because the symptoms can overlap, we evaluate the plumbing system and narrow down the source before recommending a repair.
How We Find Plumbing Leaks
Leak detection starts with the simplest checks and becomes more targeted based on what we find. Our goal is to narrow down the source before opening walls, floors, or other finished surfaces unnecessarily.
Checking for Unexplained Water Use
The water meter can help determine whether water is moving through the system when nothing should be using it. Homeowners can perform a basic check by turning off faucets, water-using appliances, and irrigation, then watching the meter for movement.
During a service visit, we can use the meter along with other plumbing tests to help determine whether the problem is inside the home or along the main water line. The results help guide where we investigate next.
Leak Detection Methods
Different leaks require different methods to locate. Depending on the symptoms and location, our plumbers may use:
- Acoustic detection to listen for water escaping from a pressurized line
- Pressure testing to help isolate a section of plumbing that may be losing water
- Thermal inspection to identify temperature differences that may indicate a hot water leak
- Visual inspection of accessible pipes, fittings, fixtures, and crawl spaces
These methods help us narrow down the source so the repair can be focused on the affected area rather than relying on guesswork.
Common Places Plumbing Leaks Develop
Leaks can develop anywhere water supply or drain lines run through a home. Some appear around visible fixtures, while others remain hidden behind walls, beneath floors, or underground.
Walls, Ceilings, and Crawl Spaces
Leaks inside walls or above ceilings may first appear as stains, peeling paint, damp drywall, or unexplained moisture. The visible damage is not always directly below the source because water can travel along pipes and framing. Crawl space leaks can also remain unnoticed for some time. Moisture beneath the home may affect insulation, subflooring, or framing before there is an obvious sign inside the living space. We inspect accessible plumbing to help identify where the water is coming from.
Slab Leaks
Plumbing beneath a concrete slab can develop leaks that are difficult to locate from the surface. Warning signs may include warm or damp areas on the floor, changes in water pressure, unexplained water use, or moisture near the base of a wall. We use leak detection methods to narrow down the affected area before recommending slab leak repair.
Main Water Line Leaks
The water line between the meter and your home can leak underground without immediately becoming visible. Unexplained water use, reduced pressure, or consistently wet areas in the yard can indicate a problem with the service line. If testing points to the main line, our water and sewer line services cover the necessary repair.
Water Heaters, Appliances, and Fixtures
Not every leak originates inside a wall or underground. Dishwasher connections, refrigerator supply lines, washing machine hoses, faucets, toilets, and other fixtures can all develop leaks. Water around a tank-style water heater can come from a connection, valve, or the tank itself. Our water heater services include diagnosing these problems and determining whether repair or replacement is appropriate. Running toilets can also waste water without leaving a visible puddle. If the problem is isolated to the toilet, our toilet repair and installation service can address the affected components.
Water Leak Repair After Detection
Once we locate the source of a leak, we explain what we found and what the repair involves. The same team that handles the detection can complete the plumbing repair, so there is no need to coordinate with a separate plumber.
Before work begins, you receive a clear estimate and have the opportunity to approve the repair. Once completed, we test the plumbing to make sure the affected area is operating properly.
Pipe Repair or Repiping
A leak in otherwise sound piping can often be addressed by repairing or replacing the damaged section. When we find broader corrosion or deterioration, repairing one spot may not address the larger condition of the plumbing system.
In those situations, we can explain whether repiping is worth considering instead of continuing to make individual repairs.
Burst Pipe Repair
A burst pipe requires quick action. If you can do so safely, shut off the home’s main water supply to stop additional water from escaping. If water is reaching electrical outlets, appliances, or other electrical components, avoid the affected area and address the electrical hazard safely.
Freezing temperatures can damage pipes in crawl spaces, exterior walls, and other vulnerable areas. If a pipe has burst or is actively leaking, our emergency plumbing services can address the damaged plumbing and help stop additional water loss.

How CB Smith handles a leak detection appointment in Spartanburg
You call and describe what you are seeing
When you reach CB Smith Plumbing at (864) 574-4275, describe the symptoms — a rising water bill, moisture on a surface, warm spots on the floor, or the sound of running water when nothing is on. That information shapes the diagnostic approach before the technician arrives.
The technician performs a systematic assessment
Your plumber begins with a whole-system review, checking water pressure, inspecting accessible pipe runs, and using the water meter to confirm whether an active leak is present. This step defines the scope of the diagnostic work needed.
Professional detection equipment is deployed
Depending on the suspected location of the leak, CB Smith uses acoustic detection, pressurization testing, or thermal inspection to narrow the source to a specific location. We do not start opening walls or floors until we have diagnostic confirmation of where the leak is.
The findings are reviewed with you before any repair begins
Once the leak is located, your technician explains exactly what was found, shows you the evidence where possible, and describes what the repair involves. You have full information before approving any work.
The repair is completed and the system is tested
CB Smith performs the repair and verifies that the leak is resolved before closing any opened surfaces or wrapping up the visit. The system is tested under normal operating pressure to confirm the fix is holding.
The work area is cleaned and the visit is reviewed
Your technician cleans the work area and walks you through what was repaired, what caused the failure, and whether any related pipe sections showed signs of deterioration that could cause problems down the road.

Frequently asked questions about leak detection in Spartanburg, SC
How do I know if I have a hidden water leak in my Spartanburg home?
The most common indicators are a water bill that has increased without any change in usage, the sound of running water when all fixtures are turned off, moisture or discoloration appearing on walls, ceilings, or floors without an obvious cause, and soft or warm spots on flooring that do not correspond to any known fixture. In homes with crawl space construction, a musty odor from below the floor is often an early indicator that moisture has been accumulating under the house. Any of these symptoms warrants a professional leak detection inspection to rule out or confirm an active leak before the surrounding damage worsens.
What is the difference between a slab leak and a regular pipe leak?
A slab leak is a leak in a supply or drain line that runs beneath a concrete foundation rather than inside a wall or in a crawl space. The symptoms can overlap — unexplained moisture, rising water bills, and floor damage — but slab leaks are distinguished by warm spots on tile or hardwood floors directly above the leak location, water appearing at the base of walls from below, and in more advanced cases, visible cracks in the slab itself. Slab leak detection in Spartanburg, SC requires pressurization testing to isolate the affected line before any excavation into the concrete begins.
Can CB Smith find a leak without tearing up my floors or walls?
In most cases, yes. CB Smith uses acoustic detection and pressurization testing to locate leaks before any invasive work begins. These methods narrow the location of the leak to a specific section of pipe, which minimizes the area that needs to be opened for the repair. The goal is always to use the least invasive approach that still provides an accurate diagnosis. Only after the leak location is confirmed and you have approved the repair scope does any floor, wall, or slab get opened.
What causes pinhole leaks in Spartanburg homes specifically?
Spartanburg’s oldest residential housing stock was built with galvanized steel supply lines that have been corroding internally for decades. As the zinc coating that protects the steel interior breaks down over time, the pipe wall thins at points of stress, particularly at elbows, fittings, and transitions where water pressure concentrates. Pinhole leaks develop at these points before the surrounding pipe section has failed entirely. In homes built between the 1940s and the 1960s, which represent the largest share of Spartanburg’s housing stock, these leaks are one of the most common hidden plumbing failures CB Smith diagnoses.
How much damage can a slow hidden leak cause before it is found?
The answer depends almost entirely on how long the leak has been active and where it is located. A slow weeping joint in a wall cavity can saturate framing and drywall for months before any visible sign appears on the surface. At that stage, the moisture has typically created conditions for mold growth and wood rot in the affected structural materials. A leak that goes undetected for a year or more in a crawl space can compromise subfloor integrity, attract pests, and require remediation work that extends well beyond the plumbing repair itself. This is why CB Smith emphasizes early detection over waiting for symptoms to become obvious.
Does CB Smith handle both the detection and the repair, or just one?
CB Smith handles both. The same team that locates the leak performs the repair. This matters practically because the technician who has diagnosed the system knows exactly what the pipe configuration looks like, where the failure is, and what the repair involves. There is no handoff to a separate crew that has to re-diagnose the situation. The result is a more efficient repair and a single point of accountability for the outcome.
