What mold testing tells you that a visual inspection cannot
Visual inspection finds where mold is growing. Lab testing tells you what is growing, how much of it is airborne, and whether mold levels in your home are elevated above normal outdoor baseline levels. This information matters for three reasons: it determines the correct remediation protocol, it gives you evidence for insurance claims, and it provides documentation for real estate transactions.
Types of mold testing we perform
Air sampling captures airborne mold spores in a measured volume of air. We take samples from affected rooms and from outdoor locations as a baseline. The lab compares indoor and outdoor spore counts by species. Elevated indoor counts confirm active mold growth even when no visible mold is present.
Surface swab sampling collects material directly from visible mold growth for species identification. This confirms whether dark growth is Stachybotrys chartarum, Aspergillus, Cladosporium, or another species. Each species has different health implications and different remediation requirements.
HVAC air sampling captures spores from your AC system at the supply vents. This finds mold inside air handlers, drain pans, and duct systems that cannot be seen during a visual inspection.
Bulk sampling collects pieces of affected material — drywall, insulation, wood — for analysis when a large area is affected and species identification guides how much material must be removed.
What the lab results show
Results come back from our accredited laboratory within 24 to 48 hours. The report identifies every mold species detected, the spore count per cubic meter of air for each species, and how indoor levels compare to outdoor baseline levels. We provide a written interpretation of the results alongside the lab report.
Post-remediation testing
After mold removal is complete, we perform a final round of air testing to confirm that mold levels have returned to normal. This post-remediation verification (PRV) test is the document your insurance company needs to close a claim and the document that confirms your home is safe to reoccupy. We include this test on every completed remediation job.
Florida law requires mold disclosure during home sales. Our written lab reports give buyers independent documentation of mold conditions and give sellers evidence of a clean clearance after remediation.
