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

Chemical sponges lift soot instead of smearing it further into the surface.
Porous drywall gets different treatment than glass, tile, or metal.
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.
Fine soot pulled from carpet, upholstery, and HVAC returns before any wet cleaning begins.
Different chemistry entirely from what porous drywall needs.
We prioritize metal surfaces early because the corrosion clock starts immediately.
Overhead surfaces carry the heaviest particulate load and need careful sponge technique.
Soot pulled into HVAC returns circulates through the whole Astoria, OR property if left alone.
A technician answers and mobilizes the fastest available crew.
Mobile units are equipped for both porous and non-porous surfaces.
You approve the scope before any sponge touches a surface.
Cleaning proceeds surface by surface with a final walkthrough.
"We tried wiping the soot down ourselves and just smeared it worse across the wall. Their dabbing technique actually lifted it cleanly." — Homeowner, Astoria
"Fast response meant our fixtures got treated before corrosion set in." — Homeowner, Astoria, OR
"I didn't expect the vacuum step to matter, but the carpets ended up much cleaner than our attempt." — Homeowner, Astoria
Wiping tends to smear fine particulate deeper into porous surfaces.
Ideally within 48 hours, since acidic residue starts pitting metal after that.
Surface type determines whether we use dry sponges or solvent cleaners.
Cleaning reduces odor, but persistent smell may need a separate treatment step.
Yes, HEPA extraction handles soft surfaces before any wet cleaning starts.
We keep response times short across Astoria because soot corrosion is time-sensitive.
