How to Remove Smoke Odor From Fire-Damaged Homes Using Thermal Fogging

The pores in the walls of a home will expand with heat.
The fire department will tell you when it's safe to re-enter your home.
When the building is on fire, the smoke odor enters these pores and remains long after the fire is extinguished. Thermal fogging is a process that forces the pores open again to release the smoke odors. The chemicals used in thermal fogging can then neutralize the odors. Professional fire restorers can treat your home with thermal fogging, or you may rent or purchase a thermal fogging machine. .

Step 1

Disable all smoke detectors to prevent false alarms.

Step 2

Turn off all pilot lights and any other potential sources of combustion. Do not allow any open flames near the home, including cigarette lighters. This could cause an explosion.

Step 3

Evacuate all pets, plants and people from the home. All people who remain in the home to work with the thermal fogging machine must wear a respirator mask.

Step 4

Close all windows and all exterior doors to keep the fog inside.

Step 5

Measure the required amount of odor absorbent chemicals. The amount you will use depends on which brand you select and the amount of space you need to treat. Consult the manufacturer's directions for the proper amount and pour it into the thermal fogging machine.

Step 6

Treat closets and rooms that you can close off before applying the fog to open areas. Pull the trigger on the fogging machine to release the chemicals. Start at the furthest point from the exit and work your way outward. Close each closet or door after you treat that area.

Step 7

Take all other precautions as recommended by the manufacturer. For instance, the manufacturer might recommend that you release the trigger after a set amount of time to allow the fogging machine to reheat.

Step 8

Exit the home immediately upon completion of the fogging. Keep the home sealed and prevent anyone from entering it for the amount of time recommended by the manufacturer. After this time period, ventilate the home thoroughly before allowing re-entry.

  • Respirator mask
