The water history a Lauderdale-by-the-Sea sample is read against
Salt on both elevations and nothing sheltered, which attacks the joints in a facade rather than the materials either side of them. Fifty years of chloride and ultraviolet on a window perimeter sealant is a long time, and the failure is progressive rather than sudden: a joint that has lost its elasticity admits a little driven rain each storm, into an assembly that has no drainage path, and the accumulation is what eventually appears inside. There is rarely a single event to point at.
That context is why the outdoor control sample is not optional here. A laboratory can tell you that a cubic metre of your air held a particular number of spores, and on its own that number is unusable, because outdoor air across Broward carries a heavy background load in every month of the year and a building is mostly breathing it.
So every job in Lauderdale-by-the-Sea starts with a cassette run in the outdoor air at the property, in the same hour, before any indoor sample is taken. Two things come out of the comparison. Count, where indoor air substantially above the outdoor air it is drawn from points at an indoor source. And species mix, which is usually the more useful of the two: when an indoor sample carries a genus the outdoor control barely registers, that difference is the finding even if the totals look ordinary.
Two limits go in the report rather than being left for you to discover. Sampling is a snapshot of one hour on one day, and a cooling system that has just cycled reads differently from one that has been off. And there is no federal or Florida numerical standard for indoor mold, so no laboratory can issue a pass or a fail. Anyone quoting a legal limit is quoting their own policy.
The commercial position in Lauderdale-by-the-Sea 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 Lauderdale-by-the-Sea itself changes
The buildings in Lauderdale-by-the-Sea
Lauderdale-by-the-Sea is a barrier island town of 6,900 units at a 1972 median, with 56% of them in buildings of fifty or more and only 15% single-family detached. Four in five homes here are in a building somebody else maintains, which is the single most important fact about assessing one. The stock is predominantly low and mid-rise oceanfront and Intracoastal-side condominium from the 1960s and 1970s, built at a scale that keeps the buildings in individual rather than professional management.
Where it hides in these buildings
Nothing useful here is inside your own front door. The source is typically at a facade, a balcony, a parapet or a unit above, so the technique is establishing direction of travel through metering and thermal imaging rather than looking for something. In a low-rise building without a facilities manager, a written finding is frequently the only thing that gets an association to open an elevation, because nobody is going to do it on a verbal complaint.
The cooling systems here
A mixture of original through-wall units and modern split systems from refurbishments, and in an oceanfront building the condenser itself lives a hard life: salt attacks coil fins and cabinets, and an efficiency loss shows up as a system that runs longer and dehumidifies less well than it should. Seasonal occupancy compounds it, because a unit shut up from May to October has spent the wet season equalising with the outdoor air at a dew point in the low seventies.
