Why smoke odor keeps coming back
Smoke smell is not just in the air. It sits in the soot on walls and ceilings, in insulation and wall cavities, in carpet pad and upholstery, and in the ductwork. Opening windows and running fans may help for a day, and sprays and candles only cover it. When the house warms up or the air gets damp, the residue releases odor again. If it isn’t removed properly, smoke odor can last for months.
Source removal comes first
Our fire damage restoration work treats odor in a fixed order, because each step depends on the one before it:
- Clean the soot. Every affected surface is cleaned first. This is the same work as our smoke and soot damage cleanup, and odor removal fails without it.
- Remove what can’t be saved. Insulation, carpet pad and porous materials with heavy smoke damage usually have to go. We photograph them for your claim before removal.
- Address the HVAC system. Ducts that are not cleaned keep pushing smoke smell into every room each time the system runs.
- Deodorize the structure. We use specialized deodorization and air purification equipment to treat the air and the building, not just the surfaces you can see.
- Seal before repainting. Where needed, cleaned surfaces are sealed so odor is not locked in behind new paint during reconstruction.
Wildfire smoke in Seattle-area homes
Not every smoke odor job follows a house fire. In late summer, wildfire smoke from fires across the region can settle over the Seattle area for days. The CDC notes that smoke can stay in the air for days after a wildfire ends. Fine soot and odor get in through windows, vents and HVAC systems, especially in older houses. The Washington State Department of Health suggests running a portable air cleaner with HEPA and carbon filters after visible ash is removed, and replacing HVAC filters monthly until the smell is gone. If the odor is still there after that, or you see fine gray dust near vents, the residue needs cleaning. Our sanitization services team handles this work too.
What you can do now
- After a house fire, don’t run the furnace or air conditioning until the system has been checked.
- Don’t paint over smoke-stained walls. It can trap the odor.
- Don’t run a consumer ozone generator. The U.S. EPA warns that ozone can be harmful to health and is not effective at removing many odor-causing chemicals at safe levels.
- Keep damaged items until your insurer has seen them, and photograph everything.
