What the equipment in Miramar can and cannot remove
Modern split systems, and in the western half systems that are frequently on their first or second replacement. The imported drywall question ties directly to the equipment here: sulphur compounds emitted by that wallboard corrode copper, and an evaporator coil that has failed well before its expected life in a house of this age is one of the recognised indicators. It is also the point at which a smell gets called mold when it is not mold at all, which is a far more expensive mistake than the inspection would have cost.
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 Miramar 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 Miramar 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 Miramar itself changes
The buildings in Miramar
Miramar runs east to west across almost the whole width of the county and its median build year of 1996 conceals that shape. The eastern end is 1950s and 1960s building on the Hollywood pattern; the western end went up through the late 1990s and the 2000s and is where most of the 46,380 units now are. Sixty-two per cent of the housing is single-family detached, which is high for South Broward. The western cohort is the one that changes what we look for, because a large share of it was built during the years when imported wallboard was arriving through Port Everglades in quantity.
Where the water comes from
West Miramar is built on land that was drained and is kept drained, which means a high water table held down by a canal system rather than by elevation. The practical effect on a building is not flooding, it is that the ground under a slab stays damp and the margin for anything else going wrong is narrower. The eastern end shares Hollywood's older stormwater picture. Across both, the wet season delivers 71% of the annual rain between May and October, and the dew point through those months sits high enough that any chilled surface is a candidate.
Where it hides in these buildings
On the western houses the difficulty is that everything is new enough to look fine. Wall cavities in a 2000s house are tight, the finishes are intact, and there is no visible history to follow, so the survey depends almost entirely on the meter and the camera rather than on anything the eye can find. Where imported drywall is a question, the evidence is in places nobody opens: behind switch and socket plates for blackened copper, and at the evaporator coil for corrosion that does not match the age of the equipment.
