Slab leak detection and repair in Duval
Florida slab construction plus hot summers equals slab leaks. We detect with thermal and acoustic tools, repair without tearing up the floor when we can.
Florida slab construction plus hot summers equals slab leaks — particularly in homes built in the 1970s, ’80s, and ’90s where the supply lines run inside the concrete. Hot-water lines fail first; cold lines follow ten years behind. Thermal imaging, acoustic listening, pressure-test isolation — we find them without tearing up the whole floor. Then we tell you whether a spot repair or a reroute makes more sense for your specific house.
Typical symptoms
- Water bill jumps without a change in usage
- Warm spot on the floor (hot-water-line leak)
- Sound of running water with everything turned off
- Mildew smell that won't go away
- Damp or buckling spot in the slab or flooring above
Scope of work
- Thermal-imaging detection (non-invasive)
- Acoustic listening (high-sensitivity)
- Pressure-test isolation (hot vs. cold side)
- Spot-repair through the slab (when accessible)
- Reroute around the slab (when not)
- Insurance-documentation photos and adjuster-ready estimates
Frequently asked
Six common questions for slab leak detection & repair.
How do you find a slab leak without tearing up the floor?
Three tools in combination. Thermal-imaging shows the heat signature of a hot-water leak through the slab. Acoustic listening picks up the sound of pressurized water escaping the pipe — different frequencies for copper vs. galvanized. Pressure testing isolates whether it's the hot side or the cold side. We don't open the slab until we've narrowed the location to within a foot or so.
Repair or reroute — what's the difference?
Repair means breaking through the slab at the leak location, fixing the pipe, and patching back. Faster, less disruption to the rest of the house — works when the leak is in an accessible spot (not under built-in cabinetry, not in the middle of finished tile). Reroute means abandoning the leaking section of pipe and running new pipe through the walls or attic to bypass it. More disruption to the wall finish, but no slab opening — sometimes the better choice in a tile-floor kitchen.
Will my insurance cover this?
Often, yes — homeowner's policies usually cover the water damage and the cost of accessing the leak, though the leak repair itself is sometimes excluded. We write the estimate in the format your adjuster needs and document the work with photos so your claim has what it needs. We can't predict your specific coverage, but we work with adjusters on Duval claims weekly.
How much does a slab leak repair cost?
Range is wide — a straightforward spot repair on an accessible run can be in the low thousands; a reroute through finished walls on a complicated layout is several times that. The free written estimate is the only honest answer. We won't give a ceiling number on the phone because every slab is different.
How quickly can you get to it?
Same-day or next-day for the detection visit on most Duval addresses. Repair scheduling depends on what we find — accessible spot repairs often go the same day; reroutes need a day to schedule and prepare. If your situation is actively wasting water (warm spot growing, ceiling stains spreading), tell us on the call — we prioritize.
