The right method for the soot you have

Smoke and soot cleanup for Los Angeles homes

Soot is not dust. Wiping it with a wet rag smears it into paint for good, and each kind of soot needs a different method.

Quick answer

Smoke and soot cleanup in Los Angeles starts by identifying the soot: dry soot from a fast fire, oily soot from plastics, or near-invisible protein residue from a kitchen fire. Dry soot comes off with dry chemical sponges and HEPA vacuums; oily and protein soot need degreasers. Surfaces that stay stained are sealed before painting.

The job

Why soot needs the right method

Soot is fine, acidic carbon that settles on every surface, including rooms far from the fire. Left on, it etches and discolors finishes within days.

The wrong method makes it worse. A damp sponge on dry soot pushes it into the paint. A dry sponge on oily soot just smears it. Where flames reached the structure, it becomes a fire restoration job.

Variations of this job

Dry soot

Dry soot comes from fast, hot fires burning wood or paper. It is powdery, sits on the surface and smudges easily. We remove it first with HEPA vacuums and dry chemical sponges, working top down from ceilings to floors, before any liquid touches the surface. Done in that order, painted walls and ceilings often clean up without repainting. Done out of order, the same walls end up needing a stain-blocking primer and two coats of paint. Light fixtures and vents are cleaned in the same pass.

Protein soot

Protein soot comes from cooking fires, where food burned on the stove. It is a thin, yellowish film that you can barely see but can smell strongly, and it clings to cabinets, walls and fabrics throughout the house. It needs degreasing cleaners and careful wiping, then odor treatment, because the smell lives in that film. People often think a kitchen fire left no damage until the smell refuses to fade. Fabrics and curtains in nearby rooms usually need cleaning as well.

Duct and HVAC soot

Duct and HVAC soot happens when the heating or air conditioning ran during or after the fire and pulled smoke through the system. Soot coats the inside of the ducts, the blower and the coil, and every time the system runs it blows soot and odor back into clean rooms. The ducts, registers and air handler are cleaned, and the filter replaced, before the system is turned back on for good. Until then, the thermostat stays off so the ducts cannot move more soot around the house.

Los Angeles conditions

Forced-air heat spreads the smoke

Across the Los Angeles and Long Beach metro, about 58 percent of homes heat with a warm-air furnace and 46 percent have central air, so a large share of houses have ducts running to every room. When a fire happens and the system runs, smoke rides those ducts into bedrooms and closets that never saw flame. That is why we check the ducts on nearly every smoke job here.
