Fort Lauderdale’s wet summers and dry winters create constant expansion and contraction stresses on boat hulls and deck fittings. In neighborhoods like Las Olas Isles and Rio Vista, vessels often sit in brackish water where salt accelerates corrosion around through-hulls and stringers. We use moisture meters and thermal imaging to trace moisture paths without tearing apart finished interiors, catching issues common in older fiberglass boats common throughout Broward County.
Downtown Fort Lauderdale marinas and Coral Ridge docks expose boats to tidal surges that push water into chain plates and window seals. Yachts in Victoria Park and Tarpon River areas frequently develop leaks at generator exhausts and air-conditioning condensate lines after heavy monsoon rains. Our technicians map these paths from the exterior inward, identifying hidden saturation in foam core before mold colonies form on cabin liners.
Nearby Pompano Beach and Oakland Park boat owners face similar challenges when vessels are trailered or stored near the Intracoastal. We test pressurized systems and deck hardware under realistic load conditions to replicate how rain and spray actually enter. This prevents repeat mold outbreaks that spread quickly once humidity climbs again after the dry season ends.
Technician insight
In Fort Lauderdale the thing that catches most people out with leak detection is how monsoon rains push water past older butyl tape on deck hardware in Las Olas Isles boats; the moisture then travels along stringers and shows up weeks later as mold on cabin soles once the dry season begins.
Hidden leak behind starboard chain plates
A 48-foot sailboat in Rio Vista showed recurring musty odors after summer rains. Moisture readings led us to the chain plate bases where water had traveled down the bulkhead. We isolated the leak with targeted testing, confirmed the path with thermal imaging, and the owner had the fittings re-bedded before mold spread further into the liner.
Leak Detection Services We Offer
✓Hull Through-Hull Leak Testing
Pressure and vacuum testing of all below-waterline fittings to locate seepage before it saturates bilge areas and triggers mold.
✓Deck Fitting Moisture Mapping
Thermal and pinless meter scans around hatches, cleats, and winches to find water entry points common on boats moored in Las Olas Isles.
✓Window and Port Seal Inspection
Detailed checks of glazing seals and frames that leak during summer storms, preventing interior panel saturation in Fort Lauderdale yachts.
✓AC Condensate and Plumbing Tracing
Ultrasonic and dye testing of air-conditioning drains and fresh-water lines that often drip behind cabinetry in Broward County vessels.
✓Chain Plate and Rigging Base Scans
Moisture detection at mast steps and shroud bases where rainwater travels downward, a frequent issue on boats docked near Fort Lauderdale Beach.

| Full hull and deck mapping | $550–$950 | Includes thermal imaging and pressure testing on typical Broward County yachts |
| AC and plumbing tracing add-on | $175–$325 | Added when condensate or fresh-water lines are suspected sources |
| Post-repair verification visit | $150–$250 | Return check after owner or yard completes recommended fixes |

How it works
- 1
Initial Visual And Moisture Survey
We walk the vessel and record baseline readings at known high-risk points using calibrated meters suited to marine fiberglass and wood.
- 2
Targeted Pressure Testing
Selected compartments are isolated and pressurized to simulate rain and wave action, revealing active leak paths without disassembly.
- 3
Thermal Imaging Confirmation
Infrared scans highlight temperature differentials caused by trapped moisture behind liners and under deck cores.
- 4
Report And Repair Recommendations
Findings are mapped to specific locations with photos and prioritized steps for stopping water entry before mold remediation begins.
Pricing
Most leak detection jobs on 35- to 60-foot vessels in Fort Lauderdale fall between a quick scan and full multi-system testing.
