What the equipment in Hillsboro Beach can and cannot remove
A mixture of original through-wall units and split systems retrofitted during refurbishments, and in a seasonally occupied tower the equipment matters less than how it is left. A unit shut up from May to October with the thermostat set high spends the entire wet season equalising with outdoor air at a dew point in the low seventies. That is the most common cause of growth in this town and it has nothing to do with the building failing.
The reason that matters is a gap between two numbers, both from the Florida Solar Energy Center at the University of Central Florida. Through the hot months, with cooling running, indoor relative humidity should not exceed 55% during the day on a regular basis. And the great majority of mold species need a material moisture content corresponding to a relative humidity of at least 70% to grow at all.
Note where that second number is measured. Not in the room. At the material. Air holds less moisture as it cools, so the film of air against a chilled surface sits at a far higher relative humidity than the room average. A wall at 68F with 78F room air at 55% is close to saturation at its own face, and it does not need a leak to get there. That is the mechanism behind almost every complaint where nobody can find a source.
So in Hillsboro Beach we read surface temperatures with an infrared thermometer alongside the room air, calculate the dew point of that air, and record the margin at every surface that has one worth recording. FSEC also give the point at which cooling alone stops being enough: sustained readings of 70 to 75% mean dehumidification rather than a colder thermostat, and turning the thermostat down at that stage chills the surfaces further and makes it worse.
The commercial position in Hillsboro Beach is the one published on every page of this site, because the rate card is not a Fort Lauderdale rate card. A flat price by property size, agreed before anyone drives out, with the accredited laboratory fee already inside it. It does not rise if the samples come back positive, nothing is added for the drive, and we take no payment of any kind from anyone who removes mold.

What Hillsboro Beach itself changes
The buildings in Hillsboro Beach
Hillsboro Beach is the most concentrated high-rise stock in Broward County: 67% of its 2,685 units sit in buildings of fifty or more, against a county figure of 17%, at a 1974 median and with 87% owner occupancy. The town is a narrow strip between the ocean and the Intracoastal, which means almost every building has salt-laden air on both elevations and no sheltered side at all. The stock is predominantly 1960s and 1970s oceanfront towers, and its problems are envelope problems rather than plumbing ones.
Where the water comes from
Driven rain is the mechanism here and it does not behave like rain on an inland building. Wind-driven water arriving at a facade under pressure finds any discontinuity in the weather line: a window perimeter seal that has had fifty years of ultraviolet and chloride, a balcony slab edge where the waterproofing has been overlaid rather than renewed, a parapet junction, a control joint. Once past that line it is inside the wall assembly and it travels sideways and down before it appears anywhere.
Where it hides in these buildings
Almost nothing here can be reached without somebody else's cooperation, which shapes the whole job. The evidence is inside a wall, on an elevation, or in a unit above. So the method is grid metering across the affected wall and ceiling to establish the gradient and therefore the direction of travel, thermal imaging to follow the cold path back, and reading that against the building's own construction. That produces a defensible statement about where the water entered without opening anything.
