Persistent odour is one of the most common reasons restoration jobs get reopened months after they were supposedly closed. Surface cleaning and consumer-grade air fresheners simply cannot reach the smoke, soot, protein, biological, and microbial volatiles that absorb into drywall, framing, insulation, HVAC ductwork, soft goods, and porous building materials. Our deodorization protocols treat the source — not the symptom.
We deploy a tiered approach matched to the specific odour profile: hydroxyl generators for occupied spaces and sensitive contents; high-output ozone for unoccupied severe-loss spaces; thermal fogging for deep penetration of porous materials; and Health Canada-compliant sealers for odours that cannot be fully neutralized in place. Every project is documented and verified before sign-off.
Coverage runs 24/7 across Kingston, Napanee, Brockville, Gananoque, Picton, Smiths Falls, Prescott, Perth, Carleton Place, Belleville, and the surrounding Eastern Ontario communities.
Our IICRC-aligned protocol
- 1
Odour source identification
On-site inspection to identify the odour profile (smoke, protein, sewage, biological, microbial), the affected materials, and the distribution path — including HVAC contamination assessment.
- 2
Source removal
Heavily contaminated and unsalvageable materials are removed under containment. Surfaces are cleaned with appropriate detergents and antimicrobials before deodorization begins — because no treatment will succeed while the source remains.
- 3
Hydroxyl or ozone treatment
Hydroxyl generators run continuously in occupied spaces; ozone is deployed in unoccupied spaces for severe losses. Treatment duration is calibrated to the odour profile and verified with on-site re-inspection.
- 4
Thermal fogging
For odours embedded in porous materials, a deodorizing fog is dispersed at temperature to penetrate the same pathways the original odour traveled — neutralizing trapped volatiles.
- 5
Sealing & final verification
Where complete in-place neutralization is not possible, Health Canada-compliant odour-blocking sealers are applied. Final verification confirms occupant-acceptable air quality before sign-off.

Why DIY deodorization usually fails
Consumer air fresheners and ozone units sold online are calibrated for nuisance odours in clean environments — not for the molecular volatiles generated by a structure fire, sewage backup, or active mould colony. They mask the odour temporarily, then it returns the moment the treatment stops. Worse, undersized ozone units used in occupied spaces can damage rubber, electronics, and respiratory health.
Professional deodorization works because it pairs the right chemistry with proper source removal, containment, and dwell time — and because the equipment outputs the concentration actually required to break the odour-causing molecules at their bonds.
Occupied-space treatment with hydroxyl
Hydroxyl radical generators are safe to operate in spaces with people, pets, and plants present. They are our default choice for residential odour treatment where the property remains occupied during restoration — common in Kingston water-loss and partial fire-damage scenarios. Treatment runs continuously for several days, and progress is verified at each crew visit.

Frequently asked questions
Will ozone treatment damage my belongings?
Ozone is used in unoccupied spaces and avoided around rubber, soft electronics, and certain plastics that ozone can degrade. We pre-stage sensitive contents to a treatment-safe location or to our climate-controlled storage during the ozone phase.
How long does deodorization take?
Typically 24–96 hours of active treatment, depending on the odour profile and the severity of the loss. Severe smoke-damage and Category 3 sewage jobs may require multiple treatment cycles plus material removal before verification.
Can you save smoke-damaged soft goods?
Most clothing, bedding, drapery, and upholstered furniture can be saved using ozone or hydroxyl treatment combined with proper laundering or ultrasonic cleaning. Items are inventoried, packed out, treated off-site, and returned cleaned and odour-free.
Will the odour come back?
Not if the source is fully removed and the treatment is verified. Recurrence almost always traces back to a missed source — typically inside wall cavities, HVAC ductwork, or insulation. Our protocols specifically map and treat those pathways.
Is odour control covered by insurance?
Yes, when the odour is the result of a covered peril — fire, smoke, water damage with microbial growth, sewage backup. We Xactimate-scope deodorization as a line item inside the parent claim.
Do you treat HVAC contamination?
Yes. HVAC systems are a primary distribution path for odours and microbial particulates after a loss. We inspect, clean, and treat ductwork as part of the deodorization scope when contamination is present.
