Water Leak Detection · Miami · Miami-Dade County

Water leak detection in Miami — non-destructive, diagnostic-only or repair-bundled

Miami homeowners call about water leak detection in three distinct situations: an obvious symptom (water bill spike, audible hiss, warm spot, musty smell) where the source is unclear; a pre-purchase real estate inspection where a buyer needs an independent plumbing assessment before closing; or an insurance claim where loss documentation requires a written diagnostic before repair work begins. Our detection service handles all three. Seven non-destructive detection technologies layered together — acoustic ground microphone, FLIR thermal infrared, hydrogen-nitrogen tracer gas, borescope camera, pressure decay testing, smart meter analysis, and zoned sub-meter isolation — pinpoint the leak source within inches before any wall or slab is touched. Diagnostic-only visits available for homeowners who want scope validation before committing to repair work.

Why detection matters before repair

Slab cuts are irreversible. Wall openings damage finishes. Pre-purchase deals fall apart on undocumented leaks. Insurance claims hinge on written pre-repair documentation. Detection done right saves money, finishes, and stress.

Signs you need water leak detection

Eight Miami-specific symptoms that trigger a detection visit

Any one of these is enough reason to schedule a diagnostic. Combinations move the urgency from "soon" to "today." We walk through each symptom with you on the phone before dispatching.

  • Water bill increase >30% without obvious household change
  • Audible hiss near a wall or floor with all fixtures off
  • Warm spot on slab floor (hot-water line under slab)
  • Persistent musty or mildew smell that doesn't go away
  • Visible stain on baseboard, ceiling, or wall finish
  • Low pressure across two or more fixtures simultaneously
  • Water meter dial moving with every fixture off
  • Hairline crack in terrazzo or tile near suspected leak path
Seven detection technologies

How we find the leak before touching any wall or slab

No single detection technology works across every Miami construction era and failure mode. We layer multiple technologies on every diagnostic visit to cross-validate results before scoping any repair work.

1

Acoustic ground microphone

Parabolic sensitive microphones detect high-frequency hiss of pressurized water escaping through pinhole or crack openings. Calibrated separately for drywall, plaster-on-lath, CBS concrete-block, FAA-soundproofed assemblies (Grapeland Heights), and Dade County pine framing (Lummus Park).

Best on copper supply leaks
2

FLIR thermal infrared imaging

Professional-grade FLIR thermal cameras detect surface temperature differentials caused by hot-water supply leaks under slab or behind walls. Particularly effective on Miami slab-on-grade where uniform substrate makes hot-water leak footprints clearly visible.

Best on hot-water lines
3

Hydrogen-nitrogen tracer gas

5%-hydrogen / 95%-nitrogen tracer gas mixture pushed through isolated supply runs. Hydrogen molecules escape through any opening and rise to surface where a tunable diode laser detector identifies the precise location. Confirms specific failing run when acoustic data is ambiguous.

Best when run is uncertain
4

Borescope camera inspection

Flexible-shaft articulating borescope cameras visualize inside wall chases, cabinet voids, behind-fixture cavities, and crawl-space access points without opening anything. Particularly powerful on pier-and-beam construction at Spring Garden and Lummus Park where crawl-space access lets us see the actual run.

Best for inaccessible chases
5

Pressure decay testing

Isolate the supply system, pressurize to 50-80 PSI, monitor decay rate over time. Calibrated decay tables identify whether a leak is present, how severe (gallons-per-hour), and which side of the meter it's on. Foundation diagnostic that informs every other test we run.

Quantifies leak severity
6

Smart water meter analysis

Miami-Dade WASD smart-meter data + on-property smart meters (Flo by Moen, Phyn Plus, Streamlabs) provide continuous flow data showing exact timestamps and flow rates of suspect leak events. Cross-reference with homeowner activity logs identifies whether flow signature matches a slow leak vs intermittent fixture use.

Confirms vs rules out leak
7

Zoned sub-meter isolation

Isolate building zones using existing shutoff valves to narrow leak location by exclusion. Particularly powerful on mid-rise residential at Brickell, Downtown, Midtown, Park West, Brickell Key where unit-level + zone-level + building-level shutoffs allow rapid isolation. Combines with pressure decay for highest-confidence narrowing.

Best for mid-rise + supertall
When detection is the right service

Four Miami situations where detection-first matters

Detection-only service is the right choice in specific situations where committing to repair scope before validating the leak source is either premature, expensive, or contractually inappropriate.

Use Case 1

Pre-purchase real estate due diligence

You're under contract on a Miami home and the seller's disclosure mentions "no known plumbing issues" — but the home is from 1956 with original Type L copper. A detection-only inspection during the due diligence window gives you written documentation of the actual plumbing condition before closing. The report is suitable for negotiating credits, requesting repair-before-close, or walking away. Common on Coral Way, Morningside, The Roads, Bay Point, and any pre-1985 Miami home purchase.

Use Case 2

Insurance claim documentation

Florida insurance carriers require written pre-repair documentation of "sudden + accidental" leak events for coverage to apply. A detection-only visit produces a dated, photographed, technologist-signed report documenting the leak source, expected repair scope, and damage path. We coordinate with public adjusters where homeowners use them; documentation is structured for direct submission to major Florida carriers.

Use Case 3

HOA dispute or scope verification

Mid-rise condo at Brickell, Downtown, Edgewater, Midtown — a leak appears in your unit but the HOA disputes whether the source is within your unit (your responsibility) or in common-area infrastructure (the HOA's responsibility). Detection-only documentation establishes the source unambiguously and provides the technical basis for the HOA's reimbursement decision or for cross-tenant subrogation.

Use Case 4

Suspected slow leak, no obvious symptom

Your water bill jumped 40% this month but you can't find a dripping fixture. Your meter dial moves slightly with everything off. Smart-meter data shows steady micro-flow overnight. Detection-only visits confirm the existence of a leak, isolate the zone (irrigation, indoor supply, pool, hot-water tank), and document for budget planning. About 18% of Miami detections we run on this signature turn out to be irrigation-system failures rather than indoor plumbing.

Detection report formats

Four report formats matched to the use case

Every detection visit ends with a written report. The format adjusts to who's going to read it and what decision they need to make from it.

Insurance claim package

Dated photographs of detected leak source, technologist-signed certification, scope-of-loss diagram, materials specifications, expected repair scope and cost estimate, and damage path documentation. Formatted for direct submission to major Florida homeowner's carriers (Citizens, Universal, Heritage, Tower Hill, others).

Pre-purchase real estate report

Plumbing system age and condition, identified deficiencies and active leaks, expected service life by component, recommended repair priorities, and budget estimates by category. Suitable for buyer negotiation, escrow credit requests, repair-before-close demands, or walk-away decision support.

HOA documentation

Source-location certification (within-unit vs common-area), responsibility analysis, cross-tenant impact documentation, and reimbursement basis. Formatted for HOA board submission; supports cross-tenant subrogation where applicable. Standard at Brickell, Brickell Key, Edgewater, Midtown, Park West, River Landing, and other mid-rise contexts.

Homeowner repair-decision support

Plain-language explanation of detected leak, why it's failing, what repair options exist with honest tradeoffs (spot repair vs reroute vs full repipe), expected repair-decision urgency, and recommended next steps. Designed for homeowners who want to understand their options before committing to scope.

Miami detection FAQ

What homeowners ask before booking a detection visit

What does a detection-only visit cost in Miami?
Diagnostic-only visits start at $325 for straightforward residential pinpoint work and run up to $475 for complex multi-zone properties (estate-scale homes, multi-structure properties, mid-rise units with extensive isolation work). Pre-purchase real estate detection runs $375–$525 depending on home age and complexity (older homes require more comprehensive walkthrough). Insurance claim documentation: $425–$575 depending on report depth required. If detection leads to immediate repair work, we apply the detection fee toward the repair invoice.
How long does Miami leak detection take?
Most Miami detection visits run 90–150 minutes from arrival to written-scope handoff. Pre-purchase real estate detection takes 2–3 hours because we walk the entire plumbing system rather than focusing on one suspected leak. Insurance-claim detection takes 2–3 hours including documentation photography and report preparation. Mid-rise unit detection takes 2–2.5 hours including building isolation testing. We share findings verbally as we work; the written report follows by email same day.
Will I need to be home during the detection visit?
For homeowner-occupied properties: yes, ideally — many findings benefit from on-the-spot discussion. For pre-purchase inspections: the buyer's agent often coordinates access without buyer present, and we deliver the written report by email afterward for buyer review. For mid-rise condos at Brickell, Downtown, etc: concierge-coordinated access can work without homeowner present if HOA permits and the unit owner pre-authorizes through property management.
Do I need detection before my plumber repairs the leak?
It depends. For obvious failures (visible burst pipe, active dripping fixture), detection isn't needed — repair is direct. For hidden failures (water bill spike, intermittent symptoms, slab leaks, multi-zone uncertainty), detection prevents the repair plumber from cutting the wrong wall or the wrong section of slab. For insurance claims or HOA disputes, detection-first documentation is often contractually required before repair scope can begin. We do both — detection-only or detection-bundled-with-repair — and explain which applies to your situation on the phone before scheduling.
I'm buying a home in Miami — should I get detection?
Yes, especially for any home built before 1985 (where Type L copper supply is at end of life), or 1985–1995 (where polybutylene cluster risk applies), or any home where seller disclosures are vague about plumbing history. Detection during the due diligence window costs $375–$525 and provides documented basis for repair-credit negotiation that often recovers 5–20× the detection cost in seller concessions. For new construction (post-2010 PEX-A), detection is less critical but still useful to verify the system is properly installed and pressure-tested.
Can you detect leaks without cutting any walls or slab?
Yes — non-destructive detection is the default. Seven detection technologies (acoustic, thermal, tracer gas, borescope, pressure decay, smart meter, sub-meter isolation) are all non-destructive. We pinpoint the leak source within inches before any wall opening or slab cut. The cut, if it's ultimately needed for repair, is then minimal and precisely placed — not exploratory. Where exploratory access is genuinely unavoidable (rare), we discuss it with the homeowner before any work and document why.
