Water damage restoration services glossary

Short, plain-English definitions of the terms you'll meet when choosing a water damage restoration service provider in Charleston SC.

Mold remediation vs mold removal: Mold remediation is the industry-standard process of controlling and reducing mold to acceptable levels, while mold removal is a marketing term implying complete elimination, which is technically impossible.
What is a Certified Mold Inspector (CMI)?: A Certified Mold Inspector (CMI) is a professional credentialed by accrediting bodies such as the International Association of Certified Indoor Air Consultants (IAC2) or the National Organization of Remediators and Mold Inspectors (NORMI) who conducts mold inspections and assessments in buildings.
What is a HEPA vacuum?: A HEPA vacuum is a specialized cleaning device that traps mold spores, dust, and other particles in a high-efficiency filter, preventing them from being recirculated into the air during water damage restoration work.
What is a mold remediation protocol?: A written scope-of-work document prepared by an assessor or inspector that specifies containment measures, personal protective equipment, and step-by-step procedures required before mold remediation work begins.
What is a mold spore?: A mold spore is a microscopic reproductive cell released by mold colonies that travels through air and settles on surfaces, serving as the basis for mold growth and airborne contamination measurement.
What is a mycotoxin?: Mycotoxins are poisonous compounds produced by certain mold species that can pose health risks when inhaled or ingested, distinct from mold spores themselves.
What is a third-party mold assessor?: An independent mold inspection professional hired separately from the remediation contractor to assess damage, write protocols, and verify work without financial conflict of interest.
What is air sampling (mold testing)?: Air sampling is a mold testing method that captures airborne spores on slides or collection media to measure indoor contamination levels and compare them against outdoor baseline counts.
What is an air scrubber?: A portable air purification machine equipped with HEPA filters that removes mold spores, dust, and other airborne contaminants from indoor spaces during restoration work.
What is an Applied Microbial Remediation Technician (AMRT)?: An AMRT is a mold remediation specialist certified by the IICRC who has completed training in identifying, containing, and removing microbial contamination from water-damaged buildings.
What is an encapsulant (mold sealant)?: An encapsulant is a liquid sealant coating applied to wood surfaces after mold remediation to lock in remaining discoloration and prevent mold spores from becoming airborne.
What is antimicrobial treatment?: Antimicrobial treatment is the application of EPA-registered biocide products to cleaned porous and semi-porous surfaces after water damage to inhibit mold and bacterial regrowth.
What is Aspergillus?: Aspergillus is a widespread genus of mold that grows indoors in damp environments, commonly appearing in green, black, or yellow colors on water-damaged materials.
What is black mold (Stachybotrys chartarum)?: Stachybotrys chartarum is a greenish-black, slimy mold species that grows in chronically wet environments and is commonly found in water-damaged buildings.
What is clearance testing?: Clearance testing is independent verification performed after remediation work to confirm a space meets safety standards and is safe for reoccupancy.
What is Condition 1, 2, 3 mold classification?: The IICRC S520 standard categorizes mold into three conditions based on spore levels and growth status to determine remediation scope and whether a property requires professional treatment.
What is HEPA filtration?: HEPA (High Efficiency Particulate Air) filtration is a mechanical filter standard that captures 99.97% of particles as small as 0.3 microns, commonly used in air scrubbers and vacuums during mold remediation and water damage restoration.
What is IICRC S520?: IICRC S520 is the professional standard published by the Institute of Inspection, Cleaning and Restoration Certification that outlines best practices for mold remediation, including containment, safety equipment, and remediation procedures.
What is mildew?: Mildew is a powdery or thin fungal growth that forms on surfaces, typically in damp areas like bathrooms, and differs from mold in that it remains on the surface rather than penetrating materials.
What is mold containment?: Mold containment uses physical barriers and air management to isolate contaminated work areas and prevent mold spores from spreading to unaffected spaces during remediation.
What is mold remediation?: Mold remediation is the controlled process of identifying, containing, removing, and cleaning mold contamination, including treatment of the moisture source that caused it.
What is negative air pressure?: Negative air pressure is a containment technique that removes air from a sealed zone through HEPA filtration to prevent mold spores and other contaminants from escaping into clean areas during remediation.
What is Penicillium?: Penicillium is a fast-growing blue-green mold that thrives in damp conditions and commonly colonizes water-damaged materials, wallpaper, and carpet in humid environments.
What is surface sampling (swab and tape lift)?: Surface sampling refers to collecting mold specimens directly from visible contaminated surfaces using sterile swabs or adhesive tape, then sending the sample to a lab to identify the specific mold species present.
