Fire Damage leaves soot deep into the surface.  Sodium bicarbonate is a very effective odor
remover, especially with our blasting method to remove most all the soot.  Some fire restoration
companies only seal the soot. Then with the heat of summer, the smoky smell can find its way
back out, down the road.  Why would anybody want to seal without soda blasting?
