What the equipment in Sunrise can and cannot remove
Individual split systems in the blocks and in the houses, with the usual county-wide sizing problem and one addition specific to a mid-size block: air handlers in closets that share a wall with a neighbouring unit, so a condensate failure in one flat appears as a stain in another. Establishing which side of the wall the equipment that failed is on is a routine part of these jobs here and it decides who pays.
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 Sunrise 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 Sunrise 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 Sunrise itself changes
The buildings in Sunrise
Sunrise carries 40,030 units at a 1983 median, with an unusually high 20% of them in buildings of twenty to forty-nine units. That mid-size block is a specific building type and it fails in a specific way: too small to have a managed central plant, too large for a single owner to make decisions about, and typically served by individual systems in each unit with shared risers and a common roof. It is the least well-served stock in the county when something goes wrong, because nobody has clear responsibility and the units share the consequences.
Where the water comes from
This is the western edge of development, immediately against the water conservation areas, and the site was made usable by drainage rather than by elevation. The water table is held down by canals and it is close to the surface, so a slab here is sitting on damp ground permanently and the local air at ground level is more humid at dawn than it is a few miles east. As everywhere on this coast, the wet season delivers 71% of the annual 66.52 inches between May and October.
Where it hides in these buildings
Low-slope and flat roof sections are common on the mid-size blocks and on a good deal of the 1980s commercial-adjacent building here, and a low-slope roof over conditioned space is the least forgiving assembly in this climate. There is no attic to buffer a failure, so water passing the membrane is immediately above a ceiling, and the insulation in that assembly absorbs and holds it. Finding the entry point on one of these requires working the gradient across the ceiling rather than looking for a drip.
