What the equipment in Lauderhill can and cannot remove
Through-wall and packaged terminal units serving individual rooms, which is the defining equipment fact in this town. That arrangement cools the room it is in and does nothing for the rest of the flat, and it has no capacity to dehumidify without cooling, which is exactly what a shoulder-season day in this county requires. The wall sleeve these units sit in is also a permanent penetration through an exterior wall, and when its drainage slope is lost the water goes inward.
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 Lauderhill 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 Lauderhill 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 Lauderhill itself changes
The buildings in Lauderhill
Lauderhill holds 30,733 units at a 1976 median, with 23% in buildings of fifty or more and 30% single-family detached. The characteristic building is the 1970s garden apartment or low-rise block: two or three storeys, external walkways, single-aspect flats and an envelope built to a specification that predates any serious attention to vapour. A flat with windows on one side only has no way to cross-ventilate, so whatever humidity the cooling equipment fails to remove has nowhere to go and no path out.
Where the water comes from
Central Broward geography with no coastal exposure, which removes the salt and facade question and leaves the ordinary wet season and a shallow water table. What tends to drive the calls here is the building rather than the weather: a 1970s block with flat or low-slope roof sections, external walkways over habitable space, and a drainage arrangement that has been patched rather than renewed at several points over fifty years.
Where it hides in these buildings
The single-aspect layout concentrates everything on one wall and one corner. The interior partition furthest from the windows is the coolest, least ventilated surface in a flat like this, and it is usually where a wardrobe stands. Inspecting these properly means moving furniture and reaching the corners rather than walking the middle of the rooms, and it is why a visual walk-through misses so much of this stock.
