How the cooling fails in Lighthouse Point
Split systems retrofitted into houses built before central cooling was standard, with the air handler squeezed into a converted closet or the garage and duct run through an attic that was never designed to carry any. The commonest single failure in this town is a condensate line routed the shortest available way rather than the best one, so that when it blocks, which it does every few wet seasons, it discharges into a wall or a floor rather than somewhere a person would notice.
Against that, one piece of building science is worth stating flatly because it is counter-intuitive enough to be missed: an oversized air conditioner dehumidifies worse than a correctly sized one, despite carrying more capacity on its nameplate.
The reason is timing. Moisture removal does not reach its full rate until roughly three minutes into a cooling cycle, because the coil has to get properly cold and wet before it strips much water out of the air crossing it. An oversized system reaches the setpoint and shuts off before it gets there. The house is cool. The house is also damp. The Florida Solar Energy Center put a worked figure on it: a building genuinely needing two tons, given four, is dehumidified worse by the larger machine despite twice the nameplate moisture capacity.
That is why so many of these calls in Lighthouse Point describe a problem that started after new equipment was fitted. The other half of the job is more prosaic and more common still: the condensate line, which carries water just condensed out of warm humid air and closes gradually with biological growth until the pan overflows into a ceiling, a closet floor or a wall. It is the highest-frequency failure in this county and the cheapest to prevent.
The commercial position in Lighthouse Point 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 Lighthouse Point itself changes
The buildings in Lighthouse Point
Lighthouse Point is a small town of 6,316 units at a 1967 median, 56% single-family detached and 77% owner-occupied, laid out almost entirely along a network of finger canals cut for boat access. The characteristic building is a single-storey concrete block house on a slab, frequently with a terrazzo or tiled floor, built at a time when nothing resembling a modern vapour strategy existed. There is no capillary break under most of these slabs and no perimeter insulation anywhere.
Where it hides in these buildings
Slab-edge moisture is invisible until flooring is lifted or furniture is moved, so the survey here concentrates on the lowest 300mm of every exterior wall and on the floor covering itself. The signature finding is a dark line at the skirting on a wall that reads perfectly dry at chest height, and it is routinely missed by an inspection that takes readings where a person naturally holds a meter.
Licensing, and who signs it off
Mold assessment is licensed by the state rather than permitted by the town, which is the opposite of how plumbing or electrical work is handled here. No Broward municipality issues a mold permit or keeps a mold register: the assessor licence comes from the Florida Department of Business and Professional Regulation under Chapter 468 Part XVI, it is searchable on the state register, and section 468.8419 bars the holder from remediating a structure they assessed within twelve months. That is identical at every address in the county and we will say so rather than inventing a local office. What matters practically in Lighthouse Point is that a building on a tidal canal with a 1960s slab has a permanent background condition rather than an event, and the report has to distinguish that from a leak, because the two have completely different remedies.
