smoke, noun. 1. visible airborne particulates from combustion. 2. invisible damage to your Woodland Hills property — for months, sometimes years.
The fire is the
opening act.
Smoke lasts.
After a fire, smoke goes to 11 places you can't see.
Visible damage is 10% of the problem. The other 90% is in your HVAC ducts, attic insulation, wall cavities, behind your cabinets, inside your fabrics. We document and decontaminate every one.
Not all smoke is the same. Not all surfaces react the same.
The cleaning chemical, equipment, and protocol depend on what burned and what it touched. We classify your loss against this matrix in the first 30 minutes on site.
| Smoke Type | Residue + pH | Surfaces hit hardest | Cleanup approach |
|---|---|---|---|
| Wet SmokeSmoldering · Low heat · Plastics, rubber | Sticky, smearypH 3.5–4.5. Webby films on cool surfaces. Worst-case for cleanup difficulty. | All porousDrywall, paint, fabric, wood. Cool surfaces (windows, mirrors, ceilings). | Solvent + degreaserWet sponging, then thermal fog. Painted surfaces often need re-paint after sealing. |
| Dry SmokeFast-burning · High heat · Wood, paper | Powdery, dustypH 4.5–5.5. Fine particulate that travels far through air handlers + cracks. | Hard surfaces + HVACGlass, stainless, electronics. Spreads fastest through HVAC system. | Dry-sponge firstHEPA vacuum, dry sponging, then ionic detergent. Avoid wet methods early — they smear residue. |
| Protein SmokeKitchen · Burnt food, grease | Yellow-brown filmpH 4.0–5.0. Often invisible at first but pungent odor. Discolors paint within weeks. | Cabinetry + appliancesYellows white surfaces. Bonds with painted wood. HVAC + ceiling fans. | Enzyme degreaserTargeted enzyme cleaning, then thermal fog deodorizer. Painted surfaces re-coated. |
| Fuel Oil SmokeHeater puff-back · Furnace failure | Black, oilypH 3.5–4.5. Heavy soot from petroleum combustion. Aggressive metal corrosion. | Whole-houseDistributed via HVAC. Coats every horizontal surface. Severe in basements + utility rooms. | Detergent + sealerWet detergent cleaning, then sealing primer where odor persists. Often needs whole-house ozone. |
Smoke damage you can't see is the kind that kills resale value 18 months later.
Most homeowners think the smell will fade. It doesn't — not without intervention. And the longer smoke sits in fabrics, HVAC, drywall, and contents, the more it bonds at a molecular level.
This is why we run a 6-step diagnostic on every WH fire-affected property — even when "the fire wasn't that bad."
Visual + thermal sweep
Walk every room. Photograph every wall, ceiling, contents area. Thermal imaging to identify cool zones where smoke condensed.
FLIR thermal camSurface pH testing
pH strips on a sample of horizontal surfaces. Acidic readings (below 6.0) confirm smoke residue chemistry — even when soot isn't visible.
Litmus + pH meterHVAC + duct inspection
Open returns, swab inside ductwork, photograph filter housing. HVAC contamination is universal in fire jobs and the #1 source of "lingering smell" 6 months later.
Boroscope + ATP swabParticulate + VOC sampling
Air sample testing for PM2.5 + volatile organic compounds. Establishes baseline + verifies post-cleanup clearance.
DustTrak + PID meterWall cavity + attic check
Drill exploratory access in suspected zones. Inspect insulation, framing, cavity surfaces. Smoke often sits hidden where the air handler returns drew it.
Borescope + UV blacklightScope writeup + categorize
Match each affected area against the smoke type × surface matrix. Cleaning chemicals + equipment selected by category. Insurance documentation packaged per S700 §15.
S700 §11–§15 docsSmoke odor doesn't sit on top. It bonds through the material.
Three levels. Three different remediation approaches. Knowing which level your damage has reached tells us what tool removes it — or whether removal is impossible and replacement is the only path.
Surface deposit
Soot + particulate sits on top of surfaces. Hasn't penetrated. Mostly removable with dry sponging, HEPA vacuuming, and detergent washing.
Embedded
Residue penetrates porous materials — drywall, paint, fabrics, wood grain. Surface cleaning leaves odor behind. Needs deeper intervention.
Molecular bond
VOCs and odor compounds bond at the molecular level with porous substrate. No treatment fully removes it. Replacement is the only sure path.
Smoke damage protocol is technical. We follow IICRC S700 to the letter.
S700 governs how smoke residue is categorized, what cleaning chemistry is allowed for each surface type, and how clearance must be verified. We don't deviate — both because shortcuts lock damage into the property, and because your insurance carrier expects S700 documentation in the file.

Smoke arrives with friends. So do we.
Fire damage restoration
Source mitigation. If the fire scope is part of your loss, we run S700 fire + smoke under one PM.
Water damage restoration
Fire-fighter water always becomes part of the scope. Extraction within 12 hours of fire-out.
Mold remediation
Wet drywall + insulation post-fire grow mold within 48 hours. We remediate before reconstruction begins.
Reconstruction & build-back
Drywall, paint, flooring, cabinetry, electrical, HVAC. Same PM from mitigation through rebuild.

What WH homeowners ask about smoke.
The fire was small. Do I really need professional smoke remediation?
How long does smoke odor remediation take?
Can I use my own air purifier or DIY ozone machine?
Will my homeowners insurance cover smoke damage?
What about smoke from wildfires that didn't actually burn my home?
How do I know if you got the smoke smell out completely?
Do I need to leave my home during smoke remediation?
How does a kitchen grease fire differ from a regular fire for smoke purposes?
The smell isn't the only thing left.
Let us find what is.
Free on-site smoke assessment. No charge for the visit. No obligation for the scope. Documented to S700 standard either way.
