Mold is everywhere
Low levels of mold spores are in all indoor and outdoor air. The question is whether levels or growth are unusual.
Start with a moisture inspection
Moisture readings and a visual inspection often answer the question and cost less than lab work.
Air samples
Air samples compare indoor spores with outdoor. They suggest whether there is a hidden source.
Surface and tape samples
These identify what is growing on a specific spot. They are useful when you are not sure if a stain is mold.
When testing helps
Testing helps for hidden odors, after remediation, for real estate questions and when a neutral result is needed.
When testing is not needed
If you can see mold, testing rarely changes the plan. Fix the moisture and remove it.
Our advice in one sentence
Find the moisture first and test only to answer a specific question.
