A hot-side slab leak
A warm spot underfoot or hot water that takes too long to reach the tap. We isolate the hot line from the cold to confirm which side is leaking before talking about repair.

Slab Leaks in Durham
Slab leak problems we see in Durham homes
From Southpoint to North Durham, these are the six situations that bring most slab leak calls.
A water bill spike
If your usage climbed and your household did not change, we check the system to find out whether water is being lost under the slab or somewhere simpler, like a toilet or a fixture.
A warm spot or wet flooring
Warm tile, damp carpet, or baseboards that swell near one wall. We use listening equipment and pressure testing to find where the water is going.
Cracked slab or plumbing leak?
Clay soil can crack a slab with no leak at all, and a leaking line can add to the damage. We test the supply lines so you know which problem you have before spending on the wrong fix.
A second opinion on a repipe quote
If someone told you to repipe the house, we locate the leak, test the system, and tell you whether a spot repair or reroute would fix it. When a repipe is the right answer, we will tell you that too.

Slab Leaks in Durham Homes
Where Durham homes get slab leaks
Durham spans many decades of building, and the risk depends on the home. Many older in-town homes in neighborhoods like Forest Hills sit on crawlspaces or basements, where we can often see the plumbing. The slab homes are more commonly the newer and mid-century suburban builds, which is where an under-floor leak is a hidden one. Homes built in the Triangle between 1978 and 1995 may have polybutylene supply piping, and older copper can develop pinhole leaks.
Durham sits on Triangle clay soil too, which swells and shrinks with the seasons and can strain lines under a slab. In neighborhoods like Southpoint, Woodcroft, and the southwest Durham subdivisions, a slab-on-grade leak is a realistic possibility, and detection matters because you do not want to open the floor in the wrong place. In older homes with galvanized or mixed piping, we look at the whole system before suggesting a repair. See leak repair for leaks that are not under a slab.
We serve Durham from our shop at 3460 Apex Pkwy in Apex, Monday through Saturday, 7:00 to 18:00. Call, text, or book online and tell us what you are seeing. For everything else in your home, see our Durham plumber page.

Helpful Details
Slab leak questions in Durham
Do you do slab leak detection in Durham?
Yes. Detection is the first step of every slab leak job. We use listening equipment, pressure testing, and hot-versus-cold isolation to locate the leak, then explain what we found and the options for repair.
How much does slab leak repair cost in Durham?
It depends on where the leak is, how many lines are involved, what the flooring is, and whether a spot repair, a reroute, or a repipe makes the most sense. We give you the price before we start, and you approve it before any work happens.
My Durham house is older. Can it have a slab leak?
Only if it is on a slab. Many older in-town Durham homes are on crawlspaces or basements, where leaks are easier to see. If your home is on a slab, we can confirm that and check the lines.
Is my floor crack caused by a slab leak?
Not necessarily. Clay soil can crack a slab with no leak. A rising water bill, a warm spot, or the sound of running water makes a leak more likely. We test the lines so you get a real answer.
Do I need a repipe after a slab leak is found?
Not always. A spot repair or a reroute may handle it. If the piping is failing in several places, a repipe can be the better long-term fix, and we will explain why before you decide.
Can you check for a slab leak before I buy in Durham?
Yes. We can pressure-test the supply lines and listen for an active leak, and we can tell you what type of piping the house has, including polybutylene in homes from roughly 1978 to 1995.
