How do you get the smoke smell out of a house after a fire?

The smoke smell lingers because tiny soot and smoke particles settle on surfaces and are drawn deep into porous materials, soft furnishings and cavities, continuing to release odour. Smoke also travels far beyond the burnt area, so rooms that were not directly affected can still smell strongly for weeks.

Airing the house does not clear the smell because the odour is held within materials rather than floating freely in the air. Opening windows, air fresheners and household sprays mask the smell briefly, but it returns as the residues continue to off-gas until they are actually removed.

Smoke odour is removed properly by cleaning soot and residue from surfaces, removing materials that cannot be salvaged, and treating the air and remaining materials with methods such as thermal fogging or ozone or hydroxyl treatment where appropriate. Only once the source is dealt with does the smell resolve for good.

Fire and smoke damage cleaning is very commonly covered by buildings insurance, which usually includes cleaning, restoration and odour treatment after a fire. A specialist can normally deal with the insurer and bill the claim directly, so the property can be restored without the owner funding it upfront.
