Treating both classes the same way is the most common soot-cleanup mistake.
Using the wrong tool on either class tends to make the residue worse.
Local Marcus Hook dispatch keeps that window from closing before we arrive.
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.
Solvent-based agents lift residue that a dry sponge would just smear across a hard surface.
Acidic residue neutralized on faucets, hinges, and hardware before pitting starts.
Sequencing matters as much as the cleaning technique itself.
A property can look clean and still be recirculating particulate through the ducts.

No return trip needed once the surface classification is done.
You see the plan split by surface class before approving anything.
The job isn't finished until every classified surface has been addressed.
"Learning that porous and non-porous surfaces get treated completely differently was new information, but it made sense once explained." — Homeowner, Marcus Hook
"Fast response on the metal fixtures meant we avoided the corrosion damage a slower crew might have missed." — Homeowner, Marcus Hook, PA
"Watching them vacuum the carpet before doing anything wet made sense once they explained wetting soot-loaded fiber just sets the stain." — Homeowner, Marcus Hook
Porous materials absorb soot into the surface itself; non-porous ones just hold it on top.
Classification happens before any cleaning tool comes out.
Roughly two days under typical conditions, which is why we prioritize metal early.
Particulate removal and odor treatment are related but distinct services.
Yes, as long as HEPA extraction happens before any wet cleaning step.
Our Soot Cleanup crews cover Marcus Hook and the surrounding zip codes, carrying tools for both surface tracks on every truck.
