Georgia Restoration Services Glossary
A working vocabulary for property restoration matters in Georgia, drawn from industry standards, licensing frameworks, and insurance practice. This glossary covers the core terminology used across water, fire, mold, storm, and structural restoration projects, with reference to the classification systems and regulatory bodies that govern restoration work in the state. Readers unfamiliar with the broader field may want to review the Conceptual Overview of How Georgia Restoration Services Works alongside these definitions.
Definition and scope
Restoration terminology in Georgia derives from two primary classification authorities: the Institute of Inspection, Cleaning and Restoration Certification (IICRC), which publishes the industry's foundational standards, and the Georgia Secretary of State's Licensing Division, which administers contractor credentials under Georgia's utility contractor and general contractor licensing statutes (O.C.G.A. Title 43). The Georgia Environmental Protection Division (EPD) of the Department of Natural Resources governs mold and asbestos-related abatement under Georgia's Air Quality Act and related rules.
The glossary is organized around five functional categories: damage classification, mitigation and remediation, structural work, contents handling, and documentation and claims. Each term below is defined as used in Georgia restoration practice, with notes on where definitions differ between insurance contexts and technical field usage.
Scope, coverage, and limitations: This glossary applies to restoration work performed on properties within the State of Georgia. It does not address federal Superfund or CERCLA cleanup designations, construction defect litigation standards, or restoration practices in other states. Commercial environmental remediation regulated exclusively under federal EPA authority falls outside this page's scope. Insurance policy interpretation is governed by Georgia's Insurance Code (O.C.G.A. Title 33) and is not covered here as legal advice.
How it works
Glossary terms function as a classification and communication layer across four parties: the property owner, the licensed restoration contractor, the insurance adjuster, and the regulatory inspector. When the same term carries inconsistent meaning across those parties, project timelines, payment disputes, and compliance failures follow. The IICRC S500 standard (water damage), S520 standard (mold remediation), and S700 standard (fire and smoke damage) each define discrete technical vocabulary that Georgia contractors are expected to apply.
Core term set — damage and classification:
- Category 1 Water (Clean Water): Water originating from a sanitary source, such as a broken supply line. Poses minimal biological risk under IICRC S500 classification.
- Category 2 Water (Grey Water): Water with significant contamination that may cause illness if ingested or exposed to. Includes overflow from washing machines or dishwashers.
- Category 3 Water (Black Water): Grossly contaminated water — including sewage, floodwater, and water from rivers or streams — that carries pathogens and requires full biohazard protocols. See the Sewage and Biohazard Cleanup page for Georgia-specific handling requirements.
- Class 1–4 Water Damage: IICRC S500 classes describe the rate of evaporation required. Class 1 is slow evaporation (minimal porosity affected); Class 4 requires specialty drying techniques for materials with very low permeance such as hardwood, concrete, or stone.
- RH (Relative Humidity): Measured as a percentage of moisture in air relative to saturation. The IICRC S500 standard targets ambient RH at or below 50% for structural drying clearance.
- GPP (Grains Per Pound): Unit of absolute moisture content in air used by drying technicians to calculate equipment capacity and drying timelines independent of temperature.
- Psychrometric reading: A set of measurements — dry-bulb temperature, wet-bulb temperature, RH, GPP, and dew point — taken to assess drying conditions and document progress. Required at each inspection cycle on monitored drying jobs.
Fire and smoke term set:
- Wet smoke residue: Dense, smeary deposits produced by low-heat, smoldering fires — typically from rubber, plastic, or synthetic materials. Requires aggressive cleaning protocols.
- Dry smoke residue: Fine, powdery residue from fast-burning, high-temperature fires. Less smearing but penetrates porous surfaces deeply.
- Protein residue: Near-invisible but strongly odorous deposit from cooking fires. Bonds to surfaces and requires enzymatic treatment. Covered under Odor Removal and Deodorization in Georgia Restoration.
- Char vs. smoke damage distinction: Char is structural — direct combustion damage. Smoke damage is a surface and air-quality issue. Insurance scope-of-work disputes frequently hinge on this boundary.
Mold and biological term set:
- Mold remediation: The physical removal and containment of mold-affected materials, per IICRC S520 and Georgia EPD guidance. Not synonymous with "mold treatment" (a topical application) or "mold testing" (an assessment activity).
- Containment barrier: Physical isolation of a work zone using polyethylene sheeting and negative air pressure to prevent cross-contamination during mold or asbestos abatement.
- CFM (Cubic Feet per Minute): Volume-flow rate used to size air scrubbers and negative air machines for contained work areas.
- Clearance testing: Third-party post-remediation verification that airborne spore counts have returned to baseline, typically performed by a Certified Industrial Hygienist (CIH). Contractors cannot perform clearance on their own work under standard practice guidelines.
Common scenarios
Scenario A — Insurance-adjuster term dispute: A Category 3 water loss in a residential property triggers debate about whether flooring qualifies as "affected" or "damaged." The IICRC S500 definition of affected materials (those within the drying zone but not structurally compromised) versus damaged materials (those requiring removal) governs scope-of-work billing. Georgia insurance adjusters and contractors frequently reference the Insurance Claims Process for Georgia Restoration Services framework to resolve these scope boundaries.
Scenario B — Mold clearance failure: A contractor completes remediation and a CIH performs clearance air sampling. Results show spore counts 3.2 times above the outdoor baseline reference sample. Under IICRC S520, the clearance fails and the remediation scope must be reassessed before reconstruction can begin.
Scenario C — Historic property terminology conflict: On a pre-1940 Georgia structure, the term "restoration" may carry a preservation-specific meaning under the Secretary of the Interior's Standards for Rehabilitation (National Park Service, 36 CFR Part 68) that is materially different from the insurance-industry definition. The Historic Property Restoration Considerations in Georgia page addresses this distinction.
Scenario D — Structural drying vs. reconstruction boundary: A licensed restoration contractor's scope ends at verified drying clearance. General construction work following that point falls under Georgia's residential and commercial contractor licensing — a separate credential category governed by the Georgia State Licensing Board for Residential and General Contractors (O.C.G.A. § 43-41).
Decision boundaries
Mitigation vs. Remediation vs. Reconstruction: These three terms define sequential phases with distinct licensing, insurance billing, and regulatory requirements.
- Mitigation covers emergency stabilization actions taken within the first 24–72 hours to prevent further loss — boarding windows, extracting standing water, deploying drying equipment.
- Remediation covers the controlled removal of damaged or contaminated materials (mold-affected drywall, char, Category 3 saturated materials).
- Reconstruction covers the rebuild phase using permitted construction work.
Georgia's contractor licensing framework assigns different credential requirements to each phase. Performing reconstruction without a residential or general contractor's license while holding only a restoration certification is a licensing violation.
Abatement vs. Remediation: Asbestos and lead abatement are governed by the Georgia EPD under the National Emission Standards for Hazardous Air Pollutants (NESHAP, 40 CFR Part 61, Subpart M) and require separate licensed abatement contractors. Mold remediation under IICRC S520 is not classified as abatement under Georgia environmental statutes, though containment and disposal protocols overlap significantly.
IICRC-certified technician vs. licensed contractor: An IICRC certification (WRT, ASD, FSRT, AMRT) is a credential issued by a private standards body and is not equivalent to a state contractor's license. Georgia law requires a contractor's license for projects exceeding specific contract thresholds; the certification alone does not satisfy that requirement. Credential details are covered on the Georgia Restoration Contractor Licensing and Credentials page.
