The water history a North Lauderdale sample is read against
The most repeated moisture complaint we could find anywhere in Broward's public forums was written from this town, and it describes the mechanism exactly: an air conditioning unit leaking water in a rented flat for five months, mold growing in it, the health department saying it could not act on apartments and code enforcement finding the unit installed improperly and without permit. That is not a weather story or a building story. It is a condensate line, and it is the most common failure in this county.
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 North Lauderdale 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 North Lauderdale 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 North Lauderdale itself changes
The buildings in North Lauderdale
North Lauderdale holds 16,396 units at a 1978 median, 36% single-family detached and 60% owner-occupied, with a substantial workforce rental component across townhouses, small blocks and manufactured homes at 4.8% of the stock. The buildings themselves are unremarkable for the period and that is the point: ordinary 1970s construction, ordinary attic air handlers, ordinary duct runs. What makes an assessment here worth the money is usually not an exotic building, it is how long a failure has been allowed to run.
Where it hides in these buildings
The place to look is wherever the air handler discharges, which in this stock is a closet floor, a garage wall or the ceiling below an attic unit. A condensate overflow is silent and it is usually behind or beneath something, so it is found by meter rather than by eye and it is frequently months old before anybody notices. Everything around and beneath the equipment gets metered on these jobs before anything else.
The cooling systems here
Split systems with the air handler in an attic, a closet or a garage. The line to check is the one carrying water that has just been condensed out of warm humid air, because biological growth inside that pipe closes it gradually and the first sign is the pan overflowing. A secondary pan with a float switch is what should stop that, and in this stock it is frequently absent, blocked itself, or disconnected because it kept shutting the system off on a hot day.
