# Smoke Damage Cleanup Ottawa and Eastern Ontario: Hydroxyl Odour Treatment, HVAC Decontamination & Contents Restoration

Last updated: September 11, 2026

Extreme Cleaning Ottawa provides 24/7 smoke damage cleanup across the National Capital Region for house fire smoke saturation, wildfire smoke intrusion, chimney fire smoke damage, electrical fire smoke residue, and HVAC ductwork smoke contamination. Our crews arrive with hydroxyl odour generators, ozone treatment units, dry chemical soot sponges, HVAC ductwork decontamination equipment, shellac-based encapsulants, and ultrasonic contents cleaning coordination for salvageable items.

According to Statistics Canada and Ottawa fire department data, residential smoke damage incidents occur regularly across the National Capital Region, with concentration during winter heating season for chimney and heating-equipment fires and during summer wildfire season for smoke intrusion events. Ottawa neighbourhoods with wood-burning fireplaces (Rockcliffe Park, Sandy Hill, Old Ottawa South) see the highest chimney fire incidence, and Ontario wildfire smoke intrusion increasingly affects properties across every neighbourhood.

Extreme Cleaning Ottawa handles house fire smoke residue restoration, wildfire smoke intrusion decontamination, chimney fire smoke damage remediation, electrical fire smoke cleanup with distinct residue protocol, HVAC ductwork smoke decontamination, ultrasonic contents cleaning coordination, and hydroxyl and ozone odour elimination with extended treatment cycles where required. Every project produces the insurance documentation adjusters accept.

We provide smoke damage cleanup throughout Ottawa and Eastern Ontario, including Kanata, Nepean, Orleans, Barrhaven, Stittsville, Gloucester, Rockcliffe Park, Vanier, Manotick, Gatineau, Aylmer, Cornwall, Kingston, Brockville, Belleville, Perth, Smiths Falls, Carleton Place, Arnprior, Kemptville, Rockland, Embrun, Casselman, Hawkesbury, Pembroke, Petawawa, and surrounding communities. Every project includes 24-hour emergency dispatch, HVAC decontamination, contents restoration, insurance direct billing on covered claims, and post-restoration odour verification.

Where This Usually Starts

## The Problems Behind Every Smoke Damage Cleanup Call

### Smoke odour comes back after cleaning

Standard smoke cleaning addresses surface residue but leaves odour compounds saturated into HVAC ductwork, structural material, and porous contents. The odour returns as compounds continue to off-gas.

### Wildfire smoke intrusion is not covered by standard claims

Ontario wildfire smoke intrusion may not qualify for standard fire damage coverage. Claim classification and documentation matter for the coverage decision.

### HVAC systems distribute smoke odour

Every time the HVAC system runs after smoke damage, it distributes residual odour compounds throughout the property. HVAC decontamination is not optional.

What This Service Covers

## What Is Smoke Damage Cleanup?

We provide 24/7 smoke damage cleanup across Ottawa and Eastern Ontario for house fire smoke saturation, wildfire smoke intrusion, chimney fire smoke damage, and HVAC ductwork smoke contamination scenarios.

Smoke damage is fundamentally about odour elimination and contamination removal that reaches every porous surface. Smoke residue penetrates HVAC ductwork within hours of any fire event, saturates upholstered contents, permeates drywall and structural surfaces, and continues to off-gas until physical removal, encapsulation, and hydroxyl or ozone treatment address it fully.

Every project starts with contamination assessment, category classification (dry smoke, wet smoke, protein smoke, or fuel smoke), coordinated dispatch, and insurance direct billing where applicable.

### What's included

-   24/7 emergency smoke damage response
-   Dry chemical soot sponge cleaning
-   HVAC ductwork decontamination
-   Hydroxyl and ozone odour elimination
-   Shellac-based structural encapsulation
-   Ultrasonic contents cleaning coordination

Smoke damage cleanup is fundamentally about odour elimination and contamination removal that reaches every porous surface throughout the property. Smoke residue penetrates HVAC ductwork within hours of any fire event, saturates upholstered contents, permeates drywall and structural surfaces, and continues to off-gas until physical removal, encapsulation, and hydroxyl or ozone treatment address it fully. Extreme Cleaning Ottawa handles house fire smoke, wildfire smoke intrusion, chimney fire smoke, and every other smoke damage scenario across the National Capital Region and Eastern Ontario.

Every project starts with contamination assessment identifying the smoke type (dry, wet, protein, fuel), penetration depth measurement, HVAC involvement scope, and contents restoration coordination. Category classification for the insurance file follows, with coordinated dispatch and direct billing where applicable.

Response is 24/7. Unmarked vehicles dispatch immediately after fire department release where applicable. Contents restoration coordination begins in parallel with the structural cleaning work.

## HVAC Decontamination. Extended Hydroxyl Treatment. Shellac Encapsulation.

Three protocols distinguish smoke damage cleanup from generic restoration response. HVAC ductwork decontamination runs as standard scope on every project with brush-and-vacuum protocol, filter replacement, and post-decontamination airflow verification. Extended hydroxyl treatment cycles running three to seven days rather than standard four-hour dispatch allow compounds to reach elimination rather than surface reduction. Shellac-based structural encapsulation traps residual saturation where cleaning cannot fully remove smoke compounds from porous structural material.

Contents restoration coordination runs alongside the structural work with ultrasonic immersion cleaning for salvageable items and non-restorable documentation for the insurance file.

## Benefits of Smoke-Damage-Specific Response Over Generic Restoration

Generic restoration companies often address smoke damage with surface cleaning and short-cycle hydroxyl dispatch. Three specific benefits smoke-damage-specific response provides:

-   **Smoke type classification.** Dry smoke, wet smoke, protein smoke, and fuel smoke require different cleaning methods and different treatment protocols. Generic response treats all smoke the same and often uses the wrong cleaning method (wet-cleaning wet smoke or dry-cleaning protein smoke), making the contamination worse.
-   **Extended hydroxyl cycles calibrated to saturation.** Standard four-hour hydroxyl dispatch addresses surface compounds but does not penetrate structural saturation. Extended cycles three to seven days long allow treatment to reach compounds off-gassed into structural material, HVAC ductwork, and porous contents.
-   **Shellac encapsulation for residual saturation.** Where cleaning cannot fully remove smoke saturation from structural surfaces, shellac-based encapsulation traps residual compounds. Latex primer applied by generic restoration does not trap smoke compounds effectively.

The cost difference between smoke-damage-specific response and generic restoration is often less than the cost of a second attempted restoration.

## Why Standard Smoke Damage Restoration Fails Without HVAC Decontamination

Most failed smoke damage restorations trace back to skipped or incomplete HVAC decontamination. Three failure modes:

-   **HVAC treated as separate contractor scope.** Generic restoration companies often exclude HVAC decontamination from the smoke damage scope, referring it to a separate HVAC contractor who does not typically address smoke residue specifically. The odour returns as the system distributes residual compounds.
-   **Filter replacement without ductwork cleaning.** Replacing HVAC filters addresses only the intake and leaves the ductwork itself saturated with smoke residue. Post-fire filter replacement without ductwork brush-and-vacuum decontamination leaves the ductwork as the ongoing odour source.
-   **No post-decontamination airflow verification.** HVAC decontamination without post-cleaning verification cannot confirm the system is clear. Smoke residue can remain in less-accessible duct runs, and verification is required to confirm the ductwork is actually clean.

Every project we run includes HVAC ductwork brush-and-vacuum decontamination, filter replacement, and post-decontamination airflow verification as part of the standard scope.

Why Choose Us

## Why Choose Extreme Cleaning Ottawa for Smoke Damage Cleanup?

### Extended hydroxyl treatment cycles

Hydroxyl treatment running three to seven days rather than standard four-hour dispatch, calibrated to saturation depth. Standard smoke damage restoration often cuts treatment cycles short and the odour returns.

### HVAC decontamination as standard scope

HVAC ductwork brush-and-vacuum decontamination, filter replacement, and post-decontamination airflow verification included in every smoke damage project. Not a separate contractor scope.

### Shellac encapsulation for residual saturation

Where cleaning cannot fully remove smoke saturation from structural surfaces, shellac-based encapsulation traps residual compounds. Latex primers do not trap smoke compounds effectively.

### Insurance direct billing

We direct-bill most Ontario carriers on covered fire and smoke claims and produce the documentation adjusters accept for structural, contents, HVAC, and encapsulation scopes.

Client Experiences

## What Customers Say About Our Smoke Damage Cleanup Work

Reviews from families, executors, and property managers across the region.

> House fire in our neighbour's property sent smoke through our HVAC system before we even knew there was a fire. The team decontaminated our ductwork, ran hydroxyl for four days, and the odour never came back.

Régine C.Rockcliffe Park

> Chimney fire in our Old Ottawa South home left smoke damage through three floors. They ran the full HVAC decontamination, coordinated the contents restoration with ultrasonic cleaning, and shellac-encapsulated the residual structural saturation.

Basim R.Old Ottawa South

> Wildfire smoke intrusion during a bad summer left our home unlivable from the odour. They handled the HVAC decontamination, the extended hydroxyl cycle, and coordinated the insurance claim with our carrier. Odour completely gone.

Questions

## Smoke Damage Cleanup FAQs

### Why does smoke damage odour keep coming back after cleaning?

Because smoke residue penetrates HVAC ductwork, structural material, and porous contents beyond the reach of surface cleaning. HVAC ductwork that has not been decontaminated continues to distribute odour throughout the property when the system runs. Structural material that has not been encapsulated continues to off-gas as compounds break down. Full elimination requires HVAC decontamination, structural encapsulation, and extended hydroxyl or ozone treatment.

### How much does smoke damage cleanup cost in Ottawa?

Isolated smoke damage with contained penetration and hydroxyl treatment typically runs $2,500 to $6,000. Multi-room smoke saturation with HVAC ductwork involvement and extended treatment cycles runs $6,000 to $14,000. Major smoke damage loss with whole-property saturation, extended structural involvement, and complete contents restoration runs $14,000 to $22,000. Direct billing is available on covered fire and smoke claims.

### Will insurance cover smoke damage cleanup in Ontario?

Standard Ontario homeowner and tenant policies include fire and smoke damage coverage. Smoke damage from a fire event on the property is typically covered. Smoke damage from neighbouring property fires may be covered depending on the policy. Wildfire smoke intrusion coverage varies by policy and depends on the specific language. We document the cause and category classification clearly for the adjuster and direct-bill covered claims.

### What are the different types of smoke damage?

Dry smoke from fast-burning fires produces powdery residue that is easier to clean but penetrates cracks and porous surfaces deeply. Wet smoke from slow-burning fires produces sticky residue that smears when wet-cleaned and requires dry chemical sponge treatment. Protein smoke from grease and kitchen fires penetrates everywhere and requires HVAC decontamination and specialized odour treatment. Fuel smoke from oil or petroleum fires produces the most persistent residue and often requires structural sealing.

### Do you handle wildfire smoke intrusion?

Yes. Ontario wildfire smoke intrusion is an increasing issue across the National Capital Region, particularly during summer wildfire seasons. Wildfire smoke penetrates HVAC systems and porous contents, and elimination requires full HVAC decontamination, extended hydroxyl treatment, and where structural saturation is documented, shellac-based encapsulation. Coverage under standard Ontario policies depends on the specific policy language.

### How long does extended hydroxyl treatment take?

Isolated smoke damage typically responds to three-day hydroxyl treatment. Multi-room saturation with HVAC involvement usually requires four to five days. Major smoke damage with whole-property saturation and structural involvement can require five to seven days of extended hydroxyl and ozone treatment. Cutting the cycle short leaves compounds in place and the odour returns.

### Do you coordinate contents restoration?

Yes. Ultrasonic contents cleaning coordination is part of every smoke damage project. Salvageable items are sent to our ultrasonic cleaning partner for restoration, non-restorable items are documented for the insurance claim, and contents return timing coordinates with the property restoration completion. Contents restoration is not a separate contractor scope.

### What is shellac-based structural encapsulation?

Shellac-based primer sealer traps residual smoke compounds in structural surfaces where cleaning cannot fully remove the saturation. Shellac creates a barrier that prevents off-gassing through the surface, allowing the residual compounds to be sealed rather than remaining a source of ongoing odour. Latex primer does not trap smoke compounds effectively, and standard restoration companies often skip the shellac step. Every project we run applies shellac encapsulation where residual saturation is documented.
