Metal fixtures get attention early since acidic residue starts pitting fast.
A standard shop vacuum does the opposite of what's needed here.

Dry-chemical sponge work lifts embedded particulate without pushing it deeper.
HEPA extraction pulls particulate before any wet cleaning ever touches the fiber.
A completely different chemistry than what porous drywall responds to.
Acidic residue neutralized on faucets, hinges, and hardware before pitting starts.
Ceilings get worked before walls so falling particulate doesn't recontaminate finished surfaces below.
Vents and returns cleaned on the same visit since they keep redistributing soot otherwise.

"I didn't realize our drywall and our tile backsplash needed totally different cleaning approaches until they explained the classification step." — Homeowner, Northfield
"They got to our kitchen faucet fast enough that it never even started pitting, which the adjuster said was lucky timing on our part." — Homeowner, Northfield, NJ
"The HEPA extraction step before any wet cleaning turned out to be the reason our carpet actually came clean." — Homeowner, Northfield
Porous materials absorb soot into the surface itself; non-porous ones just hold it on top.
Classification happens before any cleaning tool comes out.
That window is a major reason response speed matters here.
Particulate removal and odor treatment are related but distinct services.
Skipping that order is the most common way carpet soot gets set in permanently.
Response times stay short across Northfield specifically because the corrosion window on metal fixtures doesn't wait.
