A post-tension slab contains high-strength steel cables tensioned after the concrete cures. Cutting one releases thousands of pounds of stored force — genuinely dangerous, and structurally significant. So when a Castlegate home has a leak under the floor, the question is never simply 'where do we cut?' It is 'how do we fix this without cutting at all?'
Response time: Roughly 10 to 15 minutes from our Combs Rd shop.
Plumbing profile of Castlegate
Why a Hidden Leak Here Gets Expensive Fast
Under-slab leaks are silent. Water seeps into the soil beneath the floor rather than pooling where you can see it, and a modest leak can move well over ten thousand gallons in a month while looking like nothing at all. Most Castlegate homeowners find theirs through a bill, a warm spot on tile, or a hairline crack that appears in a line across the floor.
Our detection sequence is designed to prove the location before anything happens to your house: meter isolation to confirm loss, hot-versus-cold isolation at the water heater to halve the search area, then acoustic listening, thermal imaging and electronic line tracing to mark the spot and the depth. Full detail on slab leak detection and repair.
Then the repair. On the great majority of Castlegate homes we abandon the failed under-slab run and reroute overhead in PEX through the attic. No concrete, no tendon scanning, no tile to match, and the new line stays accessible for the life of the house. When a spot repair really is the better answer — a garage location, for instance — we scan for tendons with GPR before any concrete is cut. Every time, without exception.

Our work in Castlegate
On the Ground in Castlegate
We work the community and the surrounding streets toward Rancho Bella Vista, Magma Ranch and the Bella Vista corridor.
A question worth asking any plumber before you hire them in this neighborhood: how will you avoid the post-tension cables? The right answers are that they scan the slab before cutting, and that they would rather reroute overhead than open the floor at all. If the answer is a shrug and a saw, keep calling.
One Castlegate job worth mentioning: a homeowner whose water bill had roughly tripled with no visible cause. Everything indoors looked dry. Meter test confirmed active loss, isolation put it on the hot side, and acoustic listening found it under the master closet — the one room in the house nobody walks barefoot in, which is why the warm spot went unnoticed for months. Overhead reroute, one day, floor untouched.
“My bill tripled and I could not find a drop of water anywhere. They tracked it to a hot line under the master closet, which I never would have found, and rerouted it through the attic the same day. My floors were never touched.”

Why Castlegate
Why Castlegate homeowners call us
We treat post-tension slabs as the constraint they are
Castlegate foundations contain steel cables under thousands of pounds of tension. Cutting one is a structural event, not a plumbing inconvenience, and we plan every job around never needing to.
Ten thousand gallons can vanish invisibly
A Castlegate homeowner's bill tripled with no water anywhere. The leak was a hot line under the master closet — the one room nobody walks barefoot in, which is why the warm spot went unnoticed for months.
Two methods must agree before we cut
Acoustic listening, thermal imaging and line tracing. We mark location and depth on your floor and show you the readings, rather than opening concrete and hoping.
GPR scanning whenever concrete is opened
On the rare job where a spot repair genuinely beats a reroute, we scan for tendons first. Every time, without exception.
Local questions
Castlegate plumbing FAQs
It is a concrete foundation reinforced with steel cables tensioned after the concrete cures, and it is the standard across San Tan Valley. Cutting a tendon releases enormous stored force — it is hazardous and structurally significant. That is why we scan before any concrete work and why we prefer to reroute a failed line overhead instead of opening the floor.
A great deal more than people expect. Even a modest under-slab leak can move well over ten thousand gallons in a month while producing no visible water at all. That is why the meter test matters — shut everything off and watch the low-flow indicator. If it moves, water is going somewhere.
Yes. We confirm loss at the meter, isolate hot from cold at the water heater, then use acoustic listening, thermal imaging and electronic line tracing to mark the location and depth on your floor. We do not cut anything until at least two methods agree on where the leak is.
Almost certainly it does — it is the standard across the community and across San Tan Valley's post-1998 construction. Look for a stamped placard near the garage or electrical panel warning against cutting the slab, and patched anchor pockets around the slab perimeter. If in doubt, assume it does and scan before any concrete work.
Ask how they plan to avoid the post-tension cables. The right answers are that they scan with ground-penetrating radar or a cable locator before any cut, and that they would rather reroute overhead than open the floor at all. A casual answer tells you a great deal about their experience in this market.
