Fire and Smoke Deodorization

Smoke and Fire Deodorization

Strong smells often linger after having a fire.  The type of smells that develop are determined by the type of material that was on fire or smoldering.  A hot fire that burned natural building materials will smell different than that of a protein fire from frying or a slow smoldering fire that burned plastics and rubber.  These odors can cause years of problems if they are not handled by a professional.  At SERVPRO of Stone Mountain/Clarkston we employ a multi-step approach to deodorization.

Source Removal

The first step in deodorization is to find the source.  In the case of a fire the area may be obvious, however there are many causes of odor that may not be easily noticed.  Once the source is found by our trained technicians we must remove it. 

Cleaning

The next step in the process is to clean the effected areas.  Many of the soot particles are deposited both on and often inside certain building materials depending on how hot the fire was.  Our technicians are trained on different cleaning strategies dependent on the surface to be cleaned and the soils deposited.

Deodorizing

We employ a combination of pairing and masking deodorization techniques depending on the situation.  Hot fires open the pores of building materials where foul smelling soot can be deposited.  When the fire is extinguished and the materials cool down, the pores of these material shrink, thus trapping odor molecules inside.  In such cases we will use a pairing agent along with a Hot Thermal Fogger to reopen the pores.  The pairing agent will attach to and change the odor molecule so that it no longer smells.

Sealing

While sealing of wood is not always required, we will often do this on studs and structural members.  One of the reasons for sealing is because these building components are often covered up by drywall, or they are located in hard to reach areas.  Summer brings hot weather and as building materials heat up, these materials are capable of releasing odors.  Sealing ensures that any soot not completely eliminated from cleaning remains trapped.
