Under the slab
Slab Leak Detection & Repair in Englewood, CO
A warm patch on the floor, a spinning meter, a hot water system that never rests. Slab leaks located to a few feet and repaired by spot access or reroute in Englewood, CO homes.
What a slab leak is, and where they show up in Englewood
A slab leak is a supply line leaking where it runs in or under the concrete floor slab. Englewood's older core is mostly basements and crawl spaces, so classic slab-on-grade leaks are less common in a 1940s bungalow than in the newer additions, finished lower levels, and south-metro homes built on slab. Where they do happen, the Front Range's expansive clay soils are part of the story: ground that swells and shrinks with moisture puts stress on a line cast into concrete until a joint or a rub point finally gives.
The tells are specific. A hot-water slab leak often warms a patch of floor. The water heater runs more than it should because it is quietly reheating water that is leaking away. And the meter turns with every fixture shut. None of that requires breaking concrete to confirm.
Locate first, break concrete last
The costly mistake is opening the slab to go looking. We confirm the leak with a pressure test, then use acoustic and line-tracing equipment to narrow it to a few feet, so any concrete that does come up is a small, planned opening rather than an exploratory trench. Detection is the same discipline described on our leak detection page, applied to a line you cannot see.
Warm spot on the floor and a heater that never rests? That is a slab leak talking.

| Approach | When it fits | Trade-off |
|---|---|---|
| Spot repair | Single, accessible leak | Least disruption, but only fixes that point |
| Reroute | Leak in a hard-to-reach run | Abandons the bad line, avoids more slab work |
| Repipe the run | Old pipe likely to fail again | More work now, fewer callbacks later |
Which one is right depends on the pipe's age and how many leaks it has had. A single copper pinhole in an otherwise sound line is a spot repair. A line that has leaked more than once is usually rerouted or replaced, because chasing pinholes down the same run is throwing good money after bad, and at that point a planned repipe is the cheaper answer over any real horizon.
If it has already reached flooring
A slab leak that has run for a while can wet flooring, baseboards and the wall base from below. If yours has, we dry the structure with water damage restoration as part of the same visit, so you are not left with a fixed pipe and a warping floor.
Why a slab leak gets worse the longer it waits
A slab leak does not hold steady. Water under pressure escaping into or under concrete works at the surrounding soil and the slab itself, and along the Front Range's expansive clay that moisture can move the ground under the foundation over time. A hot-water slab leak also runs your water heater constantly, quietly wearing it out while it reheats water that never reaches a tap. None of that improves on its own, which is why a confirmed slab leak is worth pinpointing and repairing rather than tolerating for another season.
Questions we hear about slab leak detection & repair
How do I know it is a slab leak and not something else?
The strong signs are a persistently warm spot on the floor, a water heater that runs more than usual, and a meter that turns with everything off. We confirm it with a pressure test before locating, so you are not paying to break concrete on a guess.
Do you have to jackhammer my floor?
Only sometimes, and only after the leak is pinpointed to a few feet. Many slab leaks are better solved by rerouting the line above the slab, which avoids concrete work entirely. We pick the option with the least disruption that actually solves it.
Why did my slab leak happen at all?
Common causes are abrasion where a line rubs against the slab or rebar, a manufacturing weak point in the pipe, and soil movement. Along the Front Range, expansive clay soils that swell and shrink with moisture add stress that can find a weak joint over time.
Is one slab leak a sign there will be more?
If the line is older copper and has leaked more than once, yes, more are likely on the same run, which is why a reroute or repipe often makes more sense than a third spot repair on the same pipe.
