Why Slab Leaks Hit Cedar Park Hard
Cedar Park sits on the edge of the Edwards Plateau — literally the "lake line" where the Blackland Prairie drops into Hill Country limestone. The ground under most local homes is a mix of limestone rock and expansive clay seams. That soil swells when wet and shrinks when dry, and Central Texas delivers both extremes, sometimes within the same month.
Your water lines run through sleeves under the slab. When soil moves, those pipes flex. Copper work-hardens at the stress points, fittings fatigue, and eventually something lets go — often a pinhole, sometimes a full split. Add chloramine-treated Lake Travis water (moderately hard, with chemistry known to accelerate copper pitting over years) and it's a recipe for one of the highest-leak-rate foundation types in the Austin metro.
It's not just old houses. Cedar Park exploded from ~26,000 residents in 2000 to ~78,000 today, and new construction slabs settle for years after the pour. We find slab leaks in 20-year-old Twin Creeks homes and 3-year-old builds in Walsh Trails alike.
The Warning Signs
- Water bill climbing with no change in usage
- Warm or damp spots on floors (hot-water line leaks)
- Sound of running water when every fixture is off
- Cracks in tile, baseboards pulling away, doors that suddenly stick
- Mildew smell or damp carpet edges, especially near walls
- Water meter spinning with the house shut off
Detection Without Destruction
Our slab-leak detection combines acoustic listening gear, thermal imaging, pressure isolation testing, and line tracing to pin the leak to a small area — usually within a foot or two — before a single floor tile comes up. The $395 diagnostic fee is credited toward the repair if you hire us.
Your Repair Options, With Real Numbers
- Spot repair through the slab: best for a single leak in otherwise healthy pipe. We open the floor section, repair, and restore. Straightforward, but future leaks in the same line are possible.
- Reroute through walls/attic: abandon the failing under-slab section and run new pipe overhead. Often the smart play for chloramine-era copper that's started pinholing in multiple places.
- Tunneling: for slab leaks under kitchens or baths where floor finishes matter, we tunnel beneath from outside and patch from below.
- Whole-home repipe: if the system is failing in a pattern (see our repiping page), one-and-done beats whack-a-mole.
We'll show you camera and pressure-test results, explain the trade-offs in plain English, and quote flat. Your insurance may cover parts of this — we document everything for your claim.
After the Fix
Every slab repair we complete includes a pressure test of the full supply system, a moisture check of the surrounding slab, and — if you want it — a quote for a whole-home shut-off valve so a future leak stops itself before you're paying for foundation work.
