Slab Leaks in Apex
Most slab leak calls in Apex fit one of these six. Tell us which one sounds like yours.
A patch of tile or hardwood that feels warm with no vent nearby usually means a hot water line is leaking beneath it. On a slab home, hot-side leaks are the common case, and the warm spot also tells us which side to test first.
Usage is up and nothing in the household changed. We check whether the loss is inside the house, under the slab, or at an irrigation line before suggesting any repair.
Hearing water at night, or a meter that moves with every fixture closed, points to a leak. We rule out the water heater, a toilet, and exposed pipe first, because those are simpler to fix.
If the heater keeps firing and the hot water seems to run out sooner, hot water may be leaking away under the floor. We isolate the hot side from the cold to confirm it.
Baseboards that swell, grout that stays wet, or carpet that smells near one wall can all be water coming up from below. The sooner we find the leak, the less of the floor is affected.
If you were told the house needs a whole-home repipe, we can test the system and tell you whether a spot repair or a reroute would do it. If a repipe is the right call, we say so.
Clear Answers
The bill, the warm spot, the sound, the damp floor. We ask when it started and whether hot, cold, or both seem affected. If you can reach the main valve safely, shut it off in the meantime.
We listen along the floor, pressure-test the system, and isolate hot from cold. We locate the leak and the line it is on before proposing anything. The aim is a small opening in the right place.
You get each option with its price. A spot repair cuts through the slab at the leak. A reroute runs a new line overhead or through the walls, so the slab is left alone. A repipe replaces the failing lines. Nothing starts until you approve it.
Slab Leaks in Apex Homes
A lot of Apex was built in the last few decades, and many of the newer subdivisions, including Bella Casa, Seagroves Farm, and Jordan Pointe, are slab-on-grade. On a slab the supply lines run through or under the concrete, so a leak has nowhere visible to go. It shows up as a warm spot, a bill, or a damp floor, and not as a puddle. In a crawlspace we can see the pipe. On a slab we have to find it, which is why detection comes first.
Triangle clay swells and shrinks with the seasons and can shift a line under the slab, and copper can wear through at one spot. Hot-side lines tend to fail first because heat and flow wear the pipe. After the repair, flooring depends on the route. A reroute leaves the slab and the floor alone, aside from small openings in walls. A spot repair means cutting the slab at the leak, and we talk through what that means for tile, hardwood, or carpet before you decide. For leaks that are not under the floor, see pipe leak repair in Apex and our general leak repair page.
Our shop is at 3460 Apex Pkwy, and we work Monday through Saturday, 7:00 to 18:00. If you suspect a slab leak, shut off the main water valve if you can reach it safely and call. For everything else we do in town, see our Apex plumber page.
Helpful Details
Common signs are a water bill that jumps, the sound of running water when everything is off, a warm spot on the floor, or damp flooring. Many Apex homes are on slabs, so the leak is hidden. Call us and we will locate it before talking about repair.
We use listening equipment, pressure-test the lines, and isolate hot from cold. That narrows down which line is leaking and where, so any opening in the floor is small and in the right spot.
It depends on where the leak is, how many lines are involved, what the flooring is, and whether you choose a spot repair, a reroute, or a repipe. We give you the price before we start, and nothing happens until you approve it.
It depends on the route. A spot repair opens the floor over the leak. A reroute avoids the slab, so the flooring stays mostly intact. We explain which floors are affected before you approve the work.
Hot-side leaks are the common case, and the warm spot is a good clue. We confirm it by isolating the hot lines from the cold, not by assuming.
Yes. We locate the leak, test the system, and tell you what we find. Sometimes a repair or reroute solves it. Sometimes a repipe is right, and we say so. Call (919) 679-1275.
