Slab Leak Detection Cost: What You're Paying For
Detection is priced as a diagnostic: isolating the system, determining hot or cold side, and pinpointing the leak with acoustic, thermal, or tracer-gas equipment. Repair is quoted separately once the location is known.
Short answer
Slab leak detection is a diagnostic charge, not a repair charge. You are paying for isolation testing and pinpointing equipment that identify which line is leaking and exactly where under the concrete it is — information the repair quote depends on. Repair is priced separately, after detection.

What moves the price
- Property size and slab area to survey
- Whether flooring must be worked around
- Equipment required (acoustic, thermal, tracer gas)
- Whether the fee is credited toward repair
- Reporting needs for insurance claims
- Access to fixtures, manifolds and the water meter

Detection is a diagnosis, not a repair
A detection visit answers three questions: is water actually leaving the system, is it the hot or cold line, and where precisely is the failure. None of those are answered by looking at a wet floor, which is why guessing leads to unnecessary demolition.
Because it is diagnostic, detection is usually billed as its own service with its own fee, and the repair estimate follows. Some providers credit the detection fee toward the repair if they perform it — ask before scheduling.
What detection should deliver
- Confirmation that water is leaving the system (meter isolation test)
- Hot side vs. cold side isolation
- A marked location, not a general area
- Photos or a written report you can keep
- A written recommendation of repair options
Cost factors at a glance
| Cost factor | Why it changes the price | What to ask |
|---|---|---|
| Home size | More slab area and more fixtures means longer isolation testing | How long do you expect the survey to take? |
| Equipment used | Acoustic, thermal imaging and tracer gas differ in setup time and cost | Which methods will you use, and why? |
| Finished floors | Tile, wood and furniture slow the survey and limit sensor placement | Do I need to clear or uncover anything before you arrive? |
| Reporting | Insurance-grade documentation takes extra time on site | Is a written report with photos included? |
| Fee credit | Some providers apply the detection fee to the repair | Is the detection fee credited if you do the repair? |
| After-hours | Emergency scheduling carries a premium; detection is often not urgent | Is there a cost difference if I schedule during business hours? |
Why accuracy saves money
Precise location determines whether the fix is one small concrete opening or a reroute. Paying for good detection routinely costs less than exploratory demolition — and an undetected supply leak keeps running: EPA WaterSense estimates household leaks waste about a trillion gallons nationwide each year.
Questions to ask before hiring
- Is the fee flat or hourly, and what is the cap?
- Is the detection fee credited if you perform the repair?
- Do I get a written report with photos and a marked location?
- Will you confirm hot side vs. cold side?
- If the leak is not found, what do I owe?
- Are you licensed in Florida, and can I verify the license number?
When this becomes an emergency
- A hot spot on the floor plus rising water bills and audible running water
- Water surfacing through flooring or at wall bases
- Loss of water pressure alongside a suspected slab leak
- Any electrical fixture or outlet contacting the wet area
South Florida specifics
Slab-on-grade construction is the norm in Broward, Palm Beach and Miami-Dade, and the high water table means a small under-slab leak often shows as damp flooring rather than pooling. Detection here is normally the first paid step, not an optional one.

Frequently asked questions
Is detection credited toward the repair?
Some providers credit it if they do the repair. Ask before scheduling — it is a provider policy, not a standard.
Can I skip detection and just open the slab?
You can, but exploratory demolition is usually the more expensive path and may still miss the leak.
Does homeowners insurance pay for detection?
Some policies cover access and detection as part of a covered water loss. Ask your carrier first and keep the written report.
