FAQs
Are there state licenses for remediation and mold samplers?
For California and most states, there are no regulations, certifications, or state licensing requirements for mold remediators.
What states require licenses for remediation and mold sampling?
Several states mandate licensing for mold assessment and/or remediation professionals.
Florida, Louisiana, New York, and Texas require licenses for either mold assessors or remediators (or both). Additionally, Washington D.C. requires licensing for those engaging in residential indoor mold assessment or remediation.
If you live in one of these locations, check your state EPA / environmental agency website for the latest requirements.
Is the IICRC a state license remediation school?
No. The IICRC is a private organization that created its own industry standards. These are not EPA requirements and are not the same as a state license.
Their bylaws require technicians to disclose they are not a state agency, but this disclosure is often not made clearly.
Can mold spread on its own without water?
No. Moisture is the key ingredient for spores to grow into visible mold. If there’s no moisture source, there’s no mold growth.
Can I remove mold by myself?
Yes, you can remove mold yourself for small areas if you use the right protection and fix the moisture problem first. For larger or recurring issues, consider professional guidance.
Where does mold come from?
When first trying to understand mold, it’s important to know where it comes from.
Mold Spores
Molds have been on Earth for millions of years. Mold starts as a spore. When airborne, a spore can remain dormant because it has no moisture in or on it, making it light enough to float.
Mold belongs to the kingdom of Fungi and is a natural part of the environment. Outdoors, it plays a vital role in decomposing dead organic matter like fallen leaves and dead trees. However, mold growth should be avoided indoors.
Mold Reproduction
Mold reproduces by releasing tiny, invisible reproductive cells called spores. These spores exist in both indoor and outdoor air and can be found almost anywhere. Some molds release spores easily into the air, while others have sticky spores that cling to surfaces and are dislodged by touch.
There are always mold spores in your air space
There are always mold spores around your air space, inside or outside. Mold can enter your home through open doors, windows, vents, and heating and air conditioning systems. Outdoor mold can be brought indoors on clothing, shoes, bags, and even pets.
Mold grows where there is moisture—such as around roof, window, or pipe leaks, or after flooding. Mold can grow on paper, cardboard, ceiling tiles, wood, dust, paints, wallpaper, insulation, drywall, carpet, fabric, and upholstery.
How do mold spores grow?

Spore Germination
When a mold spore lands on a damp surface with sufficient nutrients, it can germinate and begin to grow new hyphae—restarting the mold life cycle.
The presence of moisture is crucial for spore germination and subsequent mold growth.
Spore Release and Dispersal
Spores are released into the environment and can be dispersed through air currents, water, and on surfaces like clothing or animals.
Mold spores are highly durable and can remain dormant for extended periods until they find suitable conditions to germinate.
