Smoke Damage Without a Structural Fire
A structural fire destroys what it touches. Smoke is more insidious — it spreads into rooms that never saw a flame, embeds in materials that look untouched, and keeps off-gassing long after the visible residue is gone.
This page is for smoke damage that arrives without a fire consuming your home: the grease fire that filled three rooms with oily soot before you smothered it, the furnace puff-back that coated your ceilings overnight, the electrical burnout behind a wall, the Hill Country wildfire that pushed smoke through your HVAC filters. If your property had a structural fire with suppression water and demolition, our fire damage restoration page covers that scope.
What every smoke event shares is urgency, because soot is acidic. It pits and discolors chrome and brass within hours. It etches a permanent haze into glass and mirrors within 24 to 48 hours that cannot be polished out afterward. It bridges circuits and corrodes electronics on the same clock. The difference between a cleaned home and a home where everything shiny got replaced is usually just response time.

Smoke Events We Clean Up
Not every smoke job follows a fire department response. Each of these leaves a different residue, and the residue decides the cleaning chemistry — get that wrong and you set the soot into the surface permanently.
Kitchen & Grease Fires
Protein residue from burning food is nearly invisible and the most stubbornly odorous smoke there is. Ordinary cleaners do nothing to it — every surface needs enzymatic treatment, including inside cabinets and appliances. It is why a grease fire that looked small still smells three months later.
Furnace & HVAC Puff-Backs
A furnace that accumulates fumes before igniting blows oily soot through the entire duct network and out every register at once — coating rooms nowhere near the equipment. This residue is greasy and acidic, and the air handler and ducts have to be cleaned before the system runs again.
Wildfire Smoke Intrusion
Austin ranks among the top five U.S. cities for wildfire risk, and when Hill Country fires push smoke toward the metro, standard filters cannot catch particles that fine. Smoke enters through the HVAC system and deposits throughout the house without any fire touching your property.
Electrical Burnout & Candle Soot
A failed motor or overloaded circuit burns inside a wall and pushes smoke through cavities before anyone notices. Scented and petroleum-based candles do it slowly instead — a fine greasy film on ceilings, walls, and registers that ordinary cleaning smears rather than removes.
Neighboring-Unit Fire Smoke
In condos, townhomes, and apartments, a fire next door pushes smoke through shared walls, attics, and return plenums into units that never saw flame. Your policy's smoke coverage typically applies to your unit even when the fire started elsewhere — we help you confirm before you file.
Lingering Odor After Cleanup
A house that was cleaned but still smells months later almost always has residue sealed behind paint or sitting in the ductwork — the two places quick cleanups skip. We find what was missed and treat it properly.
Why Your House Still Smells — and How We Fix It
Two things keep a cleaned home smelling like smoke: the HVAC system, and paint.
Your HVAC is what turns a one-room event into a whole-house problem. The air handler pulls contaminated air through the return and pushes it, along with particles too fine for a standard filter, out of every supply register in the building. Running it after a smoke event — trying to air the place out — is the single most damaging thing a homeowner can do. It coats the coil, lines the ducts, and embeds particulate in the insulation.
Shut it off and leave it off. Proper remediation cleans the air handler, evaporator coil, plenums, registers, and accessible duct runs, replaces the filters, and encapsulates surfaces that cannot be physically cleaned. The system does not restart until the rest of the work is done. In Austin, where HVAC runs nine or ten months a year, a contaminated system is not an inconvenience — it is a continuous exposure source.
Paint is the other culprit. Painting over smoke-stained walls traps the odor source instead of sealing it, and the solvents in the paint actually reactivate the odor compounds during application. The smell comes back through the new coat within weeks. Odor has to be handled in order: remove the residue, deodorize the material, then seal it — thermal fogging to reach wall cavities, hydroxyl generators for occupied spaces, ozone for severe events in a vacated structure, and an encapsulant primer before any finish paint.
Our Smoke Damage Cleanup Process
The sequence follows the ANSI/IICRC S700 standard for fire and smoke restoration. Your adjuster receives the documentation we build at each stage.
Call, Contain & Document
We walk you through the immediate steps on the phone — shut the HVAC, stop any fans, touch nothing — then dispatch. On arrival we close off contamination pathways with containment and HEPA-filtered negative air, and photograph the full scope before any cleaning begins.
Classify the Residue
Before any chemistry is chosen, we identify the dominant smoke type by zone — dry, oily, or protein. This is the step quick-response cleanups skip, and it is why those jobs often have to be done twice. Older homes are also screened for asbestos and lead paint before anything is disturbed.
HEPA Vacuum & Dry Soot Removal
HEPA-filtered vacuums — not shop vacs, which blow fine particles straight back into the room — pull loose soot from every surface, top to bottom. Doing this before any wet cleaning is what keeps soot from dissolving into a corrosive slurry that stains permanently.
Surface Cleaning & HVAC Decontamination
Chemistry matched to the residue: dry sponges for powdery soot, alkaline cleaners for oily, enzymatic for protein. Framing and subfloor that will be closed back up get cleaned too, because residue sealed in a wall off-gasses forever. The air handler, coil, plenums, and ducts are cleaned before the system ever restarts.
Contents Pack-Out & Restoration
Salvageable belongings go to a climate-controlled facility with a written inventory and photos for your claim. Soft goods get ultrasonic or ozone-chamber cleaning — never a normal wash cycle, which sets smoke odor permanently into fibers. Electronics are evaluated for internal corrosion.
Deodorize, Rebuild & Verify
Thermal fogging, hydroxyl, or ozone depending on how deep the odor went, then encapsulant primer before any paint. Anything that cannot be cleaned to pre-loss condition is removed and rebuilt by the same team. We close with a final inspection and hand you and your adjuster the complete project file.
What Not to Do Before We Arrive
This is worth reading even if you never call us, because the wrong first moves turn a manageable cleanup into a much larger loss.
Do not wet-wipe soot. Water and soot form an acidic slurry, and wiping a stained wall before the soot is dry-removed pushes that slurry into the pores of drywall and wood where it stains permanently. A surface a professional could clean with dry sponges in the first hours becomes unsalvageable days later.
Do not machine-wash smoke-damaged fabric. Heat and agitation drive the odor molecules deeper into the fiber and set them permanently. Clothing, curtains, and upholstery need ultrasonic or ozone-chamber cleaning instead.
Do not run fans or the HVAC to clear the air. It redistributes contamination and embeds fine particles throughout the duct network, converting a one-room problem into a whole-house one. Leave the system off until it has been decontaminated.
Do not paint over it. That traps the odor source and the paint solvents reactivate it — the smell returns through the new coat within weeks. Clean, deodorize, seal, then paint. In that order.
Smoke Damage FAQs
Straight answers to what Austin homeowners ask after a smoke event.
How much does smoke damage cleanup cost in Austin?
A contained single-room event with surface cleaning only runs a few thousand dollars. Multi-room events that also require HVAC decontamination typically run into the tens of thousands, and anything needing demolition and rebuild scales from there. The biggest drivers are the residue type — oily smoke takes far more labor than dry — how far it spread, and how much has to be replaced rather than cleaned. Written estimates are free.
How long does smoke damage cleanup take?
A contained kitchen fire with limited spread is usually three to seven days of remediation plus repainting. A moderate event through multiple rooms and the HVAC system runs two to six weeks from first response through reconstruction. Residue type, duct contamination, and how much material needs replacing set the timeline.
Does homeowners insurance cover smoke damage?
Usually yes when the smoke came from a sudden covered event — a kitchen fire, a puff-back, a fire in a neighboring unit — under both your dwelling and personal property coverage. Wildfire smoke intrusion is less predictable and depends on your policy's peril definitions. We document the source, spread, and affected materials the way adjusters expect, and give you an honest read before you file.
Can I clean smoke damage myself?
For light soot on a hard, non-porous surface — a tile backsplash after a brief pan fire — careful dry cleaning first, then wet, is reasonable. Beyond that the risk of making it permanent is real: wet-wiping bonds soot into drywall, washing sets odor into fabric, and running the HVAC spreads it everywhere. If smoke reached more than one room or entered the ducts, professional work costs less than fixing a DIY attempt.
How do I get the smoke smell out of my house?
Remove the source, then treat what remains — masking never holds. HEPA-vacuum all soot before any wet cleaning, clean surfaces with chemistry matched to the residue, decontaminate the HVAC before it runs again, then deodorize with thermal fogging, hydroxyl, or ozone depending on severity. Seal with encapsulant primer before painting. Skipping to paint is the single most common reason a house still smells months later.
Will smoke damage go away on its own?
No — it gets worse and more expensive. Soot bonds more tightly to surfaces the longer it sits, acidic residue keeps attacking metal and glass, and volatile compounds keep off-gassing from embedded residue for months. The smell does not fade; it migrates deeper into porous materials and keeps resurfacing.
How do I know if my HVAC system was affected?
Assume it was, especially if the system ran during or after the event. Telltale signs are soot around supply registers, a smoky smell when the system kicks on, discoloration inside the air handler cabinet, and filters that are gray or black rather than light. Have it inspected before running it — a contaminated system redistributes fine particles into every room it serves.
