Fire and Smoke Recovery
Learn how to get through the first days after a fire, clean light soot the right way, and remove smoke odor at its source.
What You Will Be Able to Do
- Know when it is safe to go back into a home after a fire
- Keep power and gas off until a pro checks them
- Clean light soot dry first so it does not set into surfaces
- Remove smoke odor by cleaning residue instead of masking it
- Recognize when fire or smoke damage needs a restoration crew
Lesson 1
The First 48 Hours
Do not go back inside until the fire department says the building is safe. Floors, ceilings and stairs can be weaker than they look, and hot spots can flare up again.
Call your insurer the same day and ask about living expenses if you cannot stay in the home. Secure broken windows and doors. Then photograph every room before you move, clean or throw away anything.
Key Points
- Wait for the fire department to clear the building
- Call your insurer the same day and ask about living costs
- Photograph every room before you touch anything
Lesson 2
Power and Gas Stay Off
Fire heat can damage wiring inside walls that looks fine from the outside. Firefighting water can soak outlets and the panel. Leave power and gas off until a licensed electrician or the utility turns them back on.
Treat any downed or low hanging line as live and stay far back. Breakers, outlets and wiring that were underwater usually need replacing, not drying.
Key Points
- Heat can damage hidden wiring
- A licensed electrician or the utility restores power
- Treat every downed line as live
Lesson 3
Soot Is Cleaned Dry First
Water smears soot into surfaces and can set the stain for good. So start dry. Vacuum loose soot with a HEPA vacuum, holding the nozzle just off the surface so the brush does not drag it.
Then wipe with a dry chemical soot sponge in straight, overlapping strokes. Do not scrub. Only after the dry pass should you move to a wet cleaner. Greasy or sticky soot needs a degreaser and often a pro.
Key Points
- Dry first, wet second, never the other way around
- HEPA vacuum without letting the brush touch the wall
- Wipe in straight strokes, do not scrub
Lesson 4
Small Kitchen Fires
After a small grease fire, make sure the fire is fully out and the burner and hood are cool. Vacuum dry extinguisher powder before any water touches it, since water turns it into a paste.
Kitchen smoke leaves a greasy film that soap alone will not cut. Use a degreaser. Throw out open food near the stove and replace scorched hood filters. If flames reached cabinets, the hood duct, walls or ceiling, call a pro.
Key Points
- Vacuum extinguisher powder before any water
- Use a degreaser on greasy kitchen smoke film
- Flames in cabinets, ducts or walls mean call a pro
Lesson 5
Smoke Odor Lives in Residue
Smoke odor leaves only when you remove the residue that holds it. Sprays and fresheners just cover it for a while. Clean surfaces top to bottom, wash fabrics and change the HVAC filter early and again at the end.
Some surfaces still smell after cleaning. Seal them with an odor blocking primer. Never run an ozone generator with people, pets or plants inside, since ozone harms lungs.
Key Points
- Cleaning beats masking every time
- Change the HVAC filter early and again at the end
- Ozone is never used with anyone inside
Lesson 6
Wildfire Smoke and Ash
Fine ash can carry metals and other toxic residue. Wait for the smoke to clear, then wear an N95 or P100, gloves, goggles and long sleeves. Mist ash lightly with water, then scoop or damp sweep it.
Never use a leaf blower or dry broom, which throws ash back into the air. Ash from burned homes is hazardous and is handled through the official cleanup process, not by homeowners.
Key Points
- Mist ash lightly, then scoop or damp sweep
- No leaf blowers or dry sweeping
- Ash from burned homes is left to the official process
Lesson 7
When Fire Damage Needs a Crew
Smoke travels far past the burned room, so cleaning often covers the whole home. Firefighting water adds its own drying job. Contents cleaning can be as big as the structure work.
Light soot in one or two rooms may be DIY. Any fire that burned into walls, the roof or the structure, spread smoke through the house or soaked rooms with hose water belongs to a restoration crew.
Key Points
- Smoke spreads well past the burned room
- Firefighting water means a drying job too
- Structural burns and whole-home smoke are pro jobs
