How does Servpro get rid of smoke smell?

Servpro gets rid of smoke smell after fire using multi-step odor removal process that addresses source and airborne particles. First they remove charred materials and debris that hold odor, then clean all surfaces including walls, ceilings, and contents to remove soot, which contains odor causing residues. They use HEPA air scrubbers to filter airborne soot particles and deodorize air. For odor neutralization, Servpro uses thermal fogging which creates fine deodorizing fog that penetrates porous materials similar to how smoke penetrated, ozone treatment which oxidizes odor molecules in unoccupied space, and hydroxyl generators which are safer for occupied spaces. They also clean HVAC ducts to remove smoke from ductwork, use odor counteractants and deodorizing sprays, and may seal surfaces with odor sealing paint if needed. Textiles and contents are cleaned in ultrasonic tanks or dry cleaning. The process is thorough because smoke odor can be trapped in drywall, wood, and soft materials, so combination of cleaning, filtration, and deodorization is needed to eliminate smell rather than just masking it.
