Soot behaves differently on porous drywall than it does on non-porous tile or metal, and our San Francisco, CA technicians adjust technique accordingly.

Chemical sponges lift soot instead of smearing it further into the surface.
We match method to material, not the other way around.
Soot turns corrosive on metal within about 48 hours — we move quickly.
Standard vacuums push soot particles back into the air — ours don't.

The primary method for lifting soot from drywall and painted trim without smearing.
Vacuuming first prevents particulate from smearing once surfaces get wet.
Different chemistry entirely from what porous drywall needs.
We prioritize metal surfaces early because the corrosion clock starts immediately.
Ceilings get cleaned first so falling residue doesn't recontaminate clean walls.
Cleaned on the same visit, not a separate appointment.
A technician answers and mobilizes the fastest available crew.
Crews arrive with HEPA vacuums and dry-chemical sponges on board.
Surfaces assessed by type before a written price is quoted.
Cleaning proceeds surface by surface with a final walkthrough.
"Our own attempt made the streaks worse — the sponge technique they used actually worked." — Homeowner, San Francisco
"Fast response meant our fixtures got treated before corrosion set in." — Homeowner, San Francisco, CA
"I didn't expect the vacuum step to matter, but the carpets ended up much cleaner than our attempt." — Homeowner, San Francisco
Wiping tends to smear fine particulate deeper into porous surfaces.
Ideally within 48 hours, since acidic residue starts pitting metal after that.
Yes, porous and non-porous surfaces respond to completely different agents.
Cleaning reduces odor, but persistent smell may need a separate treatment step.
Carpets get vacuumed first to prevent smearing during later steps.
We keep response times short across San Francisco because soot corrosion is time-sensitive.
