A hot-side slab leak
Hot water that is slow to arrive, a heater that never seems to stop, or a warm patch on the floor. We separate the hot side from the cold to confirm which line is losing water.

Slab Leaks in Raleigh
Slab leak problems we see in Raleigh homes
Whether you are in central Raleigh or out past the Beltline, most slab leak calls look like one of these.
A water bill spike
If the bill jumped and nothing changed in your household, we check whether water is leaking inside the house, under the slab, or at the meter side, so you know before you spend anything on repairs.
A warm spot or damp flooring
Warm tile, buckling laminate, or carpet that will not dry. These point to a leak below, and we use listening equipment and pressure testing to find the exact location.
Cracked slab or plumbing leak?
Cracks, uneven floors, and sticking doors can come from soil movement alone. We test the supply lines to tell you whether water is part of the story or the slab is just settling.
A second opinion on a repipe quote
Got a repipe quote and want to be sure? We locate the leak, test the system, and tell you if a spot repair or reroute would be enough. If a repipe is needed, we will say so and explain why.
Leak detection before buying a home
Raleigh has plenty of slab homes with decades of age on the plumbing. Before you close, we can test the supply lines for an active leak and check what the piping is.

Slab Leaks in Raleigh Homes
Slab leaks across Raleigh's housing stock
Raleigh is a big city with several eras of housing, and the leak risk differs by era. Older homes have older copper, and copper supply lines can develop pinhole leaks as they age. Homes built in the Triangle between 1978 and 1995 may have polybutylene supply piping, which can fail at the fittings. In a slab home, either one can leak out of sight.
Raleigh sits on Triangle clay soil, which swells when it is wet and shrinks when it is dry. That movement can strain supply lines running under a slab, and it can also crack the slab itself. Those two problems look alike from the living room, so we test the plumbing before we say which one you have. Newer subdivisions in North and West Raleigh have newer piping, but they are not exempt, and a repair there is often a clean spot repair. For leaks that are not under a slab, see leak repair.
We serve Raleigh 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 all our Raleigh service, see our Raleigh plumber page.

Helpful Details
Slab leak questions in Raleigh
How does slab leak detection work in Raleigh homes?
We listen along the floor and the supply lines with sensitive equipment, pressure-test the water system, and isolate the hot side from the cold side. Together those narrow the leak to a line and a location, so any opening in the floor is small and in the right place.
What does slab leak repair cost in Raleigh?
It depends on the location of the leak, how many lines are involved, the floor finish, and whether you choose a spot repair, a reroute, or a repipe. We give you the price before we start, and nothing is done until you approve it.
Do you handle slab leaks throughout Wake County?
We serve Raleigh and the surrounding Wake County towns, including Apex, Cary, Holly Springs, and Morrisville. Call (919) 679-1275 with your address and we will confirm what we can do for you.
Is my floor crack a slab leak?
Not necessarily. Clay soil can crack a slab without any plumbing leak. A bill that has gone up, a warm spot, or the sound of running water makes a leak more likely. We test the lines so you are not guessing.
Another company quoted a full repipe. Do I need one?
Maybe, maybe not. We will locate the leak and check the condition of the system. If a spot repair or reroute fixes it, we will say so. If the piping is failing throughout, a repipe is the better answer, and we will explain why.
Can you test for a slab leak before I buy a house in Raleigh?
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.
