Leak Detection
A plumbing leak isn't always easy to see. Water can travel behind walls, underneath floors, through cabinets, or along plumbing lines before you notice obvious signs of a problem. Garner Plumbing Services provides residential leak detection throughout Northeast Georgia to help homeowners identify where water is coming from and determine the right solution.

Residential Leak Detection in Winder, GA
A visible drip under a sink is usually easy to identify, but some plumbing leaks can remain hidden until they cause noticeable water damage. Unexplained moisture, water stains, musty odors, changes in water usage, or the sound of running water can all indicate that water is escaping somewhere in your plumbing system.
Garner Plumbing Services can evaluate these warning signs and work to identify the source of the leak. Finding the problem early can help homeowners address the underlying plumbing issue before continued water exposure creates additional damage to the property.
Common Signs of a Plumbing Leak
Plumbing leaks don't always announce themselves with a puddle of water. Paying attention to changes around your home can help you recognize a potential leak before the problem becomes more serious.
Unexplained Water or Dampness
Moisture under cabinets, around toilets, near appliances, or in other areas where water shouldn't be present can indicate a leaking supply line, drain, fixture, or pipe. Even a small amount of recurring moisture deserves attention.
Water Stains or Discoloration
Brown, yellow, or otherwise discolored areas on ceilings, walls, cabinets, or flooring may be signs that water is reaching the surrounding materials. A stain can remain even after the area dries, so it's important to determine whether an active leak is still present.
Unusually High Water Usage
If your water usage increases without a corresponding change in how much water your household is using, a plumbing leak may be one possible explanation. A leak can allow water to run continuously even when faucets and fixtures are turned off.
Sounds of Running or Dripping Water
Hearing water running when your fixtures and appliances are not in use can be another warning sign. Dripping, hissing, or other unusual sounds near plumbing fixtures or walls may warrant further investigation.
Where Hidden Plumbing Leaks Can Occur
Plumbing leaks can develop in many different areas of a home. Some are easy to access, while others can be hidden from view.
1. Behind Walls and Ceilings
Supply lines and other plumbing components can run through walls and ceilings. A leak in one of these areas may first appear as a water stain, damp spot, or change in the surrounding material.
2. Under Sinks and Cabinets
Kitchen and bathroom cabinets contain several plumbing connections that can develop leaks over time. Supply lines, shutoff valves, drain connections, and fixture connections can all be potential sources of water.
3. Around Toilets, Showers, and Tubs
Bathroom fixtures have multiple water and drainage connections. Leaks around a toilet, shower, or tub can sometimes be difficult to distinguish from other sources of moisture, particularly when water is traveling underneath surrounding materials.
4. Around Appliances and Water Lines
Appliances that use water, such as dishwashers and refrigerators with water connections, can also develop leaks. A small leak from a supply line or connection can create moisture in cabinets or flooring before the source is obvious.
Why Finding the Source Matters
Treating visible water without identifying where it is coming from may only address part of the problem. If the underlying plumbing leak continues, water can keep reaching areas of the home where it can damage building materials or create additional plumbing problems.
Leak detection focuses on identifying the source so that the appropriate repair can be made. The sooner a leak is identified, the sooner the plumbing problem can be addressed and further water exposure can be limited.
Leak Detection and Plumbing Repair
Finding a leak and repairing it are two related but separate parts of addressing a plumbing problem. Once the source has been identified, the appropriate repair depends on what is causing the leak and where it occurs.
A leaking fixture connection may require a different repair than a damaged pipe behind a wall. Garner Plumbing Services can evaluate the source of the problem and explain the recommended repair based on the condition of the plumbing involved.
Leak Detection for Kitchens and Bathrooms
Kitchens and bathrooms contain many of the plumbing fixtures and water connections found throughout a home, making them common locations for residential leaks. A leaking sink connection, toilet supply line, shower connection, appliance water line, or other plumbing component can allow water to reach cabinets, flooring, walls, or other surrounding materials.
If your leak appears to be related to a kitchen or bathroom fixture, Garner Plumbing Services can help identify the source and determine whether a repair or fixture-related service is needed.
What to Do When You Suspect a Leak
If you believe you have a plumbing leak, don't ignore the warning signs simply because the source isn't obvious. If water is actively leaking and you can safely identify the appropriate shutoff valve, turning off the water supply to the affected fixture can help limit water flow until the problem can be evaluated.
Avoid disturbing areas that may contain electrical components or attempting repairs beyond your experience. If you're unsure where the water is coming from, professional leak detection can help identify the source and determine what needs to happen next.

Leak Detection FAQs
How do I know if I have a hidden plumbing leak?
Common warning signs include unexplained moisture, water stains, musty odors, unusually high water usage, sounds of running or dripping water, and changes to flooring, walls, or cabinets. A hidden leak may not produce an obvious puddle, so changes around your home can be important clues.
Can a plumbing leak occur behind a wall?
Yes. Plumbing supply lines and other components can run through walls and ceilings, and a leak in these areas may not be visible immediately. Water stains, damp areas, or changes in wall or ceiling materials can indicate that water is reaching the area.
Can a small leak cause significant damage?
A small leak that continues over time can expose surrounding materials to moisture and potentially cause additional damage. Identifying and repairing the source can help prevent continued water exposure.
Does a high water bill mean I have a leak?
An unexplained increase in water usage can be one indication of a plumbing leak, particularly if your household's water use has not otherwise changed. Other causes are possible, so the plumbing system may need to be evaluated to determine what's happening.
Can Garner Plumbing repair the leak after finding it?
Yes. Garner Plumbing Services provides both leak detection and plumbing repair. Once the source and cause of the leak are identified, the team can explain the recommended repair.
Does Garner Plumbing offer emergency leak service?
Yes. Garner Plumbing Services offers 24/7 emergency plumbing service. If you have a significant active leak or another urgent plumbing problem that could cause property damage, contact Garner Plumbing Services for emergency assistance.
