Slab Leak Repair in Frisco, TX
Warm spot on the tile. Water bill that doubled. Meter that won't stop spinning. We locate slab leaks electronically, mark the exact spot before we quote, and repair or reroute so you're not tearing up half a Frisco home.
Why Frisco Homes Get More Slab Leaks Than the Rest of DFW
Most of Frisco was built on top of three different soil types stitched together — Austin chalk on the western ridges near Phillips Creek Ranch and Newman Village, Eagle Ford shale in the low draws, and pockets of Houston Black clay through the older Starwood and Panther Creek sections. Each moves differently through wet springs and 105-degree Julys, and the copper supply lines under your slab pay for it.
On top of that, the Frisco Lakes side of town regularly runs 85 to 90 PSI from the city main. Copper is rated to handle it, but not indefinitely — especially the thin-wall Type M copper that a lot of 2005–2015 tract builders used. When you combine high pressure, hot water, and shifting soil, you get pinhole leaks under the slab, usually on the hot side, usually near the primary bath.
We've chased enough of them across Frisco to know where they hide. That's why our trucks stock everything we need to detect, reroute, or slab-cut in a single visit.
Six Signs You Have a Slab Leak in Your Frisco Home
Catch these in the first week and you save thousands. Wait a month and you're paying for flooring, drywall, and possibly foundation work too.
A patch of tile or wood that's noticeably warm — even when nobody has run hot water for hours — is a hot-side slab leak until proven otherwise.
A $40 jump from one month to the next, with no change in usage, is the single most common way Frisco homeowners find out. Pull up your last three bills before you call.
Shut every fixture off. If you still hear water moving inside a wall or under the floor, that's the leak. This one is unmistakable at 2 a.m.
Locate your water meter at the curb, shut the main, and watch the small dial. Any movement means water is leaving the pipe somewhere it shouldn't.
A slab leak washes soil out from under the foundation. New or growing cracks in your Frisco home's brick or interior walls often follow within weeks.
A single-line slab leak on the hot side quietly steals your hot water pressure. If the shower on one side of the house dropped off, get it checked.
Detection First, Jackhammer Never Without Proof
Every step is written down and every option is priced before we touch your floor.
- 1Confirm it's a slab leak, not a wall leak
We shut every fixture, isolate the meter, and read your pressure. If the meter still spins, we know water is escaping — and the pressure signature tells us hot vs cold side before we lift a tile.
- 2Locate the leak electronically
Acoustic listening on the slab plus a helium tracer when the leak is too small to hear. We mark the exact spot on your floor with tape and photograph it — no exploratory jackhammering.
- 3Scan for post-tension cables and rebar
Nearly every Frisco home built after 1995 sits on a post-tension slab. Before any cut, we scan the concrete so we don't strike a tensioned cable or a rebar grid.
- 4Quote both a reroute and a slab-cut repair
You get written pricing for an overhead PEX reroute AND a slab-cut spot repair, plus an honest recommendation. You choose — we don't upsell you into the more profitable option.
- 5Repair, pressure-test, and restore
We complete the chosen repair, pressure-test the line to 100+ PSI, pull any required City of Frisco permits, patch concrete, and coordinate flooring restoration if you want us to.
Overhead Reroute vs Slab Cut Repair
On about half our Frisco slab leaks, a reroute saves the floor entirely. Here's the honest tradeoff.
We abandon the leaking line under the slab and run a new PEX line through the attic to the fixture. No concrete cutting, no flooring damage, no dust.
- Typically finished same day
- No slab or flooring restoration cost
- New line won't shift with the soil again
- Best for single-line hot-side pinhole leaks
We cut through the floor directly over the marked leak, repair or replace the affected section, then patch concrete and coordinate flooring restoration.
- Best when the leak is right at the fixture
- Preserves the original copper distribution
- Cut is typically 1–2 sq ft, not the whole room
- Flooring restoration billed separately
Post-Tension Slab or Pier-and-Beam? Your Foundation Changes the Fix
Frisco spans two eras of home construction. Knowing which one you have is the difference between a clean repair and an expensive mistake.
Almost every Frisco home built in Phillips Creek Ranch, Newman Village, Richwoods, Frisco Lakes, and the 2000s+ tract subdivisions sits on a post-tension slab. The steel cables inside the concrete are under thousands of pounds of tension — a random jackhammer strike can snap one and turn a plumbing job into a foundation job. We pre-scan the slab with a rebar/PT locator on every cut so the cable network stays intact.
- PT cable locate before any concrete cut
- Slab reroute through the attic is usually the safer play
- We coordinate with a structural engineer if a cable is compromised
Older sections of Frisco still have pier-and-beam and conventional rebar slabs from the era before Frisco's population boom. Pier-and-beam actually makes slab leaks easier — the copper runs through an accessible crawlspace, so we can repair or replace a line without touching a single floor tile. On the older rebar slabs, spot repairs are cleaner because there are no tensioned cables to worry about.
- Crawlspace access on pier-and-beam — no demolition
- Rebar slabs allow straightforward spot repair
- Common on homes originally on well or older municipal lines

What We See Where in Frisco
A slab leak in Newman Village looks different than one in Frisco Lakes. Here's where we work and what we find.
Built during the 2010s tract wave with thin-wall copper on the hot side. We see pinhole leaks under the primary bath here most often.
Larger custom slabs and long copper runs. When one line fails, we usually recommend rerouting the whole hot manifold overhead in PEX.
Older Frisco homes with 20+ years on the original copper. Recurring warm spots and pressure drops usually point to more than one weak joint.
Incoming pressure regularly hits 85–90 PSI here. Every slab leak we chase in Frisco Lakes gets paired with a PRV inspection.
Mixed soil under the neighborhood shifts unevenly. Cracked tile lines and hot-side pinholes are the most common calls.
Older section with cast iron drains beneath the slab. When a slab leak here shows sewage smell too, we camera the drain in the same visit.
