What This Is
Smoke damage cleanup addresses the soot deposits, corrosive combustion byproducts, and persistent odor that affect areas beyond the direct burn zone. It is governed by IICRC S700 — the same standard as fire damage restoration — but often presents as a separate scope because smoke may penetrate the entire home while structural fire damage is localized. Smoke damage is frequently filed as a standalone claim for events like chimney fires, neighbor fires with heavy smoke exposure, small appliance fires, and fireplace accidents where no structural fire damage occurred.
When You Need This Service
- ✓A kitchen fire, chimney fire, or appliance fire produced heavy smoke throughout the home
- ✓A neighbor's fire event caused your home to receive significant smoke exposure
- ✓A fireplace or wood-burning stove malfunction has deposited soot in rooms beyond the fireplace
- ✓Smoke odor persists after a fire event even after the burn area has been addressed
- ✓HVAC ductwork has distributed soot through the entire home during a fire event
- ✓A candle, grease, or small cooking fire left visible soot on walls, ceilings, or HVAC components
Every Hour Costs You
Soot is acidic and does not stop reacting with surfaces when it dries. Within 24 hours, soot begins permanently etching glass, discoloring grout, and staining porous surfaces including drywall and ceiling texture. Within 48–72 hours, soot tarnishes chrome and metal fixtures, begins degrading fabrics, and penetrates into HVAC systems where it will continue distributing throughout the home every time the system runs. The longer soot contact time extends, the more surfaces require replacement rather than cleaning. A chimney fire with visible soot on living room walls that is cleaned within 4 hours may save those walls entirely; the same event at 72 hours often requires full drywall replacement in affected rooms.
Our Restoration Process
- 1
Smoke Penetration Assessment
Full structure walk-through to map soot deposition zones, identify HVAC contamination, and determine cleaning protocol per IICRC S700 for each material type. Walls, ceilings, contents, HVAC, and attic space are assessed independently.
- 2
Content Protection and Pack-Out
Salvageable contents are inventoried and either cleaned on-site or packed out to a controlled environment for professional restoration. Contents documentation is the foundation of your personal property claim.
- 3
Dry Cleaning Sponge and HEPA Vacuum Phase
Dry cleaning sponges remove loose soot from ceilings, walls, and surfaces before wet cleaning. This sequence matters — wetting soot before dry-removing it grinds it into the surface and increases the area requiring replacement.
- 4
Wet Chemical Cleaning
pH-specific cleaning agents address the residual soot film that dry-cleaning cannot remove. Different materials require different chemical approaches — the same product used on painted drywall cannot be used on natural stone or hardwood.
- 5
HVAC System Cleaning and Decontamination
Ductwork, air handlers, coils, and registers are professionally cleaned to prevent ongoing smoke odor distribution. In severe events, ductwork replacement is more cost-effective than cleaning and is typically insurance-covered.
- 6
Thermal Fogging or Hydroxyl Odor Remediation
Thermal fogging (for occupied structures after air clearance) or hydroxyl generators address smoke odor by oxidizing odor molecules in wall cavities, insulation, and structural framing — areas chemical cleaning cannot reach. This step must precede any new drywall or finishes.
- 7
Finish Restoration and Rebuild
Drywall, paint, flooring, and interior finishes that could not be cleaned are replaced by Revolve's in-house crews. All rebuilding follows the insurance scope and is performed to current Missouri code.
Insurance Coverage
Typically Covered
- ✓Smoke and soot cleanup throughout the structure from a covered fire event
- ✓HVAC system decontamination or replacement when contaminated by smoke
- ✓Odor remediation treatments (thermal fogging, hydroxyl, ozone for unoccupied structures)
- ✓Contents cleaning or replacement for smoke-damaged personal property
- ✓Drywall, paint, and finish replacement in areas that cannot be cleaned to pre-loss condition
Typically Not Covered
- ✗Smoke damage from chronic sources — years of cigarette smoke, fireplace creosote buildup (maintenance exclusion)
- ✗Pre-existing smoke odor or staining not related to the covered event
- ✗Improvements or upgrades beyond like-kind-and-quality replacement
Insurance Note
Smoke damage from a covered fire event is included in the fire peril under standard HO-3 policies. However, insurers sometimes issue initial estimates that separate the smoke scope from the structural fire scope and apply lower values to the smoke cleanup line items. Revolve documents smoke penetration zones with photos and air quality data and ensures the smoke cleanup scope is fully included in the claim. For standalone smoke events (chimney fire without structural damage, neighbor fire), the same fire peril applies — the fire does not have to occur inside your home to produce a covered smoke damage loss.
How Soot and Smoke Damage Surfaces Over Time
Most homeowners who experience a fire or smoke event notice the obvious — dark soot deposits on ceilings and walls in the affected area. What they don't see immediately is the secondary damage that develops in the days and weeks following the event. Soot contains sulfur compounds, carbon particulates, and a range of organic pyrolysis byproducts that react chemically with the surfaces they contact. On painted drywall, soot leaves a permanent yellow-brown stain that primer and paint cannot cover without sealing. On copper plumbing and electrical components, it accelerates oxidation. On glass surfaces, it etches within 48–72 hours.
HVAC systems are the most dangerous vector for spreading smoke damage beyond the initial event area. If the HVAC system was running during or after the fire, smoke was drawn through the return duct, deposited throughout the ductwork, and distributed to every room with a supply register. This means rooms that had no visible smoke exposure may have soot on horizontal surfaces, inside cabinet interiors, and inside the air handler itself.
IICRC S700 protocols require assessment of HVAC contamination as a standard part of every smoke damage cleanup scope. Skipping this step is the single most common reason smoke odor returns weeks after a 'completed' remediation — the ductwork was never addressed.
Odor: Why It Comes Back and How to Eliminate It
Smoke odor is one of the most persistent and challenging aspects of fire and smoke restoration. Homeowners who have paid for smoke cleanup and then noticed odor returning two or three months later almost always find the same explanation: the odor treatment addressed surfaces but not the smoke molecules that penetrated into structural framing, insulation batting, and wall cavities.
Surface cleaning — even professional IICRC S700 cleaning — cannot reach odor sources inside wall assemblies. Thermal fogging, hydroxyl generation, and in unoccupied structures ozone treatment are specifically designed to penetrate these spaces. Thermal fogging uses a petroleum-based or water-based deodorant in particle sizes small enough to follow the same pathways smoke took during the original event. Hydroxyl generators produce hydroxyl radicals that oxidize odor molecules on contact — the same process that occurs naturally in the atmosphere but at accelerated concentrations.
The critical sequencing requirement: odor remediation must be completed before any new drywall or interior finishes are installed. Installing new drywall over a wall cavity that still contains smoke odor simply seals the odor source behind a new surface, where it will off-gas into the living space for years. Revolve sequences every fire and smoke project with odor clearance before finish installation — not as an optional extra.
Standalone Smoke Claims: When Fire Didn't Happen in Your Home
Not every smoke damage claim involves a fire inside the insured structure. Chimney fires that are contained to the firebox but produce heavy smoke throughout the home are among the most common standalone smoke claims. Neighboring property fires, particularly in dense St. Louis neighborhoods with close setbacks, can expose a home to significant smoke penetration through soffit vents, attic louvers, and open windows. Small appliance fires — a microwave, a clothes dryer — can fill a home with smoke without producing any structural fire damage.
For standalone smoke claims, the covered peril is still fire — the smoke originated from a fire, even if that fire occurred outside or in a contained appliance. Most HO-3 policies cover smoke damage from a 'hostile fire' (one that escapes its intended boundary) without requiring structural fire damage to the insured structure. The documentation requirement is the same: before-and-after air quality, surface soot mapping, and HVAC assessment.
The most common mistake on standalone smoke claims is underscoping. A chimney fire may produce less visible soot than a kitchen fire but drive significant smoke penetration into wall cavities and attic space. Revolve assesses the full penetration extent — not just what's visible — before we build the insurance scope.
Do Not Do This
Do not run your HVAC system after a smoke event until the ductwork has been assessed. Operating the system draws smoke residue from contaminated ducts into every room of the home and redistributes soot onto clean surfaces, significantly expanding the cleanup scope and cost.
Frequently Asked Questions
Can I clean smoke damage myself with consumer products?+
Surface smoke deposits on non-porous surfaces (glass, tile) can be cleaned with appropriate products, but wall-surface soot, ceiling texture, HVAC contamination, and any structural penetration cannot be adequately addressed with consumer products. DIY cleaning that grinds soot into drywall texture creates a permanent stain that requires full drywall replacement. Call us before attempting cleaning.
We aired out the house for a week and the smell is mostly gone. Do we still need professional cleanup?+
Airing reduces the concentration of airborne smoke particles but does not remove soot from surfaces, ductwork, or wall cavities. The smell 'going away' is perception adjustment, not remediation — the soot is still reacting with surfaces and will produce renewed odor, especially in humid conditions. Professional treatment is the only way to achieve durable odor elimination.
Our HVAC was running during the fire. Does the whole system need replacement?+
Not necessarily replacement, but definitely professional cleaning. Whether the ductwork can be cleaned or needs replacement depends on the extent of soot deposition, the age and type of ductwork, and the cost comparison. Flex duct with heavy soot is often more cost-effectively replaced than cleaned. Sheet metal ductwork typically cleans successfully. We assess and recommend based on actual conditions, not a blanket policy.
Is smoke damage from a neighbor's fire covered by my homeowners policy?+
Yes, in most cases. If the smoke originated from a 'hostile fire' — one that escaped its intended containment — and caused damage to your property, the fire peril in your HO-3 policy typically applies regardless of where the fire physically occurred. Document the event with fire department incident reports and photograph all smoke damage before any cleaning.
The adjuster says our smoke cleanup should only take 3 days. That seems short. Is that right?+
For a small contained area with no HVAC involvement, 3–5 days may be reasonable. For whole-house smoke penetration with HVAC decontamination and odor treatment, 7–14 days is more typical. If the adjuster's scope does not include HVAC cleaning and odor remediation as separate line items, those are items Revolve will document and include in a supplemental claim.
