What mold testing includes
- An outdoor sample from the same visit
- Air samples in living areas and closed rooms
- A sample near floor registers in raised homes
- Wall-cavity samples in walls that got wet
- Accredited lab results with a written explanation
Mold Testing in New Orleans: local factors
Neither Louisiana nor the federal government sets a limit for indoor mold. In a city this humid, outdoor spore levels can be high too, so a New Orleans result only makes sense next to outdoor air sampled at the same visit. Where growth is already visible, the EPA's view is that sampling seldom changes what has to be done.
After a storm or an outage
When a house sat closed in the heat, samples in bedrooms, closets, and the main living area, set against outdoor air, show whether indoor levels are elevated and which rooms need the most attention. That helps decide what can be cleaned and what has to go.
Raised homes
Air from under a raised floor rises into the rooms through gaps around pipes and registers. A sample near the floor vents, compared with a room upstairs or across the house and with outdoor air, shows whether the space under the house is feeding the indoor air.
Buying a renovated house
Many New Orleans homes have been renovated after storms. Home inspectors note what they see, but most do not sample. If the house took water in the past or the report mentions stains or a smell, lab work during your inspection period adds evidence; see mold and home inspections.
Proving the job is done
Louisiana licenses remediators but sets no clearance number. Before work starts, agree on what will count as finished, for instance dry readings, no visible growth, and indoor results comparable to outdoors, and choose a tester who has no stake in the remediation contract.
Price
Each lab sample costs about $50 to $350 nationally according to HomeGuide, and the visit is extra. A post-storm test with samples from several rooms quickly approaches the price of a full inspection, which Angi puts at $300 to $1,000. If the source still needs finding, book a mold inspection in New Orleans; removal is covered under mold remediation in New Orleans.
Scheduling a test
Tell the company what happened and what you need to decide. They will suggest which rooms to sample and price it before booking; the call is free.

Licensing for mold testing in New Orleans
Louisiana does not license mold testing. Ask who takes the samples, which accredited lab analyzes them, and whether the tester is separate from the remediation company. State law also bars the tester from cleaning up the same job, so lab results here come from someone with no stake in the removal bill.
