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
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.
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 leaksFLIR 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 linesHydrogen-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 uncertainBorescope 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 chasesPressure 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 severitySmart 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 leakZoned 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 + supertallFour 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.
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.
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.
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.
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.
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.
