Smoke, Soot & Puffback Remediation

After a puffback, a chimney smoke event, or a small fireplace fire, the visible cleanup is the easy part — it's the embedded smoke odor and the soot driven into walls, ceilings, soft goods, and HVAC ducts that lingers and quietly ruins a home's comfort. We remediate smoke and soot the only way that actually works: not by masking the smell, but by removing the soot source and neutralizing the odor molecules with professional thermal-fog and hydroxyl treatment.

A puffback — a furnace or chimney blowing soot back into the living space — spreads an oily, acidic soot that bonds to surfaces, plus a sharp smoke odor ordinary cleaning can't reach. Spraying air freshener over it is the consumer mistake; the odor returns because the source is still there. We begin by removing the soot itself: HEPA-vacuuming and cleaning it off the firebox, hearth, and affected surfaces, and dealing with the soot pulled into the HVAC system, because coated ductwork keeps re-circulating the smell with every cycle. We clean and encapsulate the duct soot and swap the filters.

Whatever odor remains is treated at the molecular level. We thermal-fog the affected spaces — a heated fog that penetrates the same porous materials and tight gaps the smoke did, neutralizing odor where it actually settled — and run hydroxyl or ozone generators to break down embedded smoke odor in soft goods and finishes. On smoke-stained drywall and ceilings, we seal with a pigmented shellac/oil stain-blocking primer so neither the stain nor the odor can bleed back through new paint. That stain-block step is critical: paint alone over soot-stained framing lets the smell and discoloration ghost back within months.

The premium difference is completeness and sequence. Soot removal, HVAC de-sooting, molecular odor treatment, and stain-blocking all have to happen, in that order. We also pin down and address the cause so it doesn't repeat — a puffback usually points to a combustion or draft problem, a mis-firing burner or a spilling flue — diagnosing and correcting (or coordinating) the underlying issue so you're not remediating the same event next season. We document the work so the scope is verifiable for you and, where a claim is involved, your insurer.
