How Fire Restoration Actually Works
Fire damage breaks into three distinct categories that each need different handling: visible burn damage (charred materials that must be removed), soot deposition (fine particulate that adheres to every surface in the affected area and often beyond), and smoke odor (volatile compounds absorbed into porous materials throughout the structure). Most homeowners focus on the visible burn area; the soot and odor work is usually 60-70% of the total restoration scope.
Soot removal follows a sequence per IICRC S700: dry sponging first to remove loose soot without smearing, then chemical sponging on smoke film, then wet wash on washable surfaces, then HEPA vacuum on porous materials. Doing these out of order spreads the soot deeper into substrate and makes the job harder.
Odor neutralization uses hydroxyl generators (preferred over ozone for occupied spaces) plus thermal fogging in heavily-affected areas. The goal is to neutralize the odor compounds at the molecular level, not just mask them. Done right, the odor is gone permanently. Done wrong (or skipped), it returns within weeks.
HVAC decontamination is critical because forced-air systems redistribute soot through the entire house during the fire and afterward. Every supply and return duct gets cleaned with the source-removal method (rotating brush + HEPA negative-air vacuum) before the system is allowed to run again.
