Elimination of odors

Odors in your ducts often come from mold, bacteria, or stagnant air. We eliminate the cause—not just the scent.
Eliminating ventilation odors

Does your home or office still smell funny even after you've cleaned? The smell keeps coming back and you don't know what to do?

Le problème vient probablement de votre ventilation system qui redistribue les mauvaises odeurs partout.

Where do these stubborn odors come from?

Common sources in residential ducts

  • Hidden mold that thrive in humidity
  • Animal waste (mice, squirrels, bats)
  • Dust accumulation mixed with moisture
  • Kitchen odors embedded in the system
  • Cigarette smoke absorbed by the ducts
  • Pet fragrances concentrates

Problems specific to commercial buildings

  • Industrial chemicals that accumulate
  • Restaurant odors in shared systems
  • Building materials fumes recent
  • Commercial cleaning residues that mix

Our 5-step elimination process

1. Diagnosis by olfactory and visual inspection

Our technicians identify the exact source with professional odor detectors and a endoscopic inspection camera.

2. Complete mechanical cleaning

We physically remove all odour-trapping residues: encrusted dust, animal debris, greasy build-up.

3. Specialized neutralizing treatment

Application ofbiological enzymes which break down odour-causing molecules at source.

4. Controlled ozone deodorization

Our industrial ozone generator oxidizes odor compounds at the molecular level (used only when safe).

5. Long-lasting odor protection

Spraying a antimicrobial coating which prevents new odors from taking hold.

Types of odors that can be effectively eliminated

Organic odors

  • Moulds and fungiSmell of damp cellar or earth
  • Animal decomposition: When rodents died in the ducts
  • Fecal matterPets or vermin
  • Concentrated urineParticularly tenacious in older systems

Combustion odors

  • Cigarette smoke: embedded for years in the conduits
  • Furnace sootWhen the system has gone wrong
  • Burning smellsAfter overheating of electrical equipment

Chemical and industrial odors

  • Paints and solvents: After major renovations
  • Cleaning productsMixing residues to create new odors
  • Synthetic fragrancesDeodorants that mask without eliminating

Specialized odor elimination equipment

  • Variable ozone generatorsFor controlled oxidation of compounds
  • Enzyme nebulizersHomogeneous diffusion of biological agents
  • Ionization systemNeutralizing odorous particles in suspension
  • High-power extractors: Complete evacuation of treated vapors
  • VOC detectorsMeasuring volatile organic compounds
  • Professional hygrometers: Controls odor-causing humidity

Disposal products used

Emergency situations requiring rapid intervention

After death of animal in system

The smell of decomposition spreads rapidly throughout the building. The longer you wait, the harder it is to eliminate completely.

Sewer back-up in ducts

When drainage systems fail, sewage odors rise up through the ventilation system. This is an immediate health hazard.

Smoke damage after fire

Fine soot penetrates everywhere in the flues. Without professional treatment, the burning smell lingers for years.

Recent rodent infestation

Pheromones and animal urine create odors that attract other pests. The cycle must be broken quickly.

Preventing recurring odors

Humidity control

Maintain less than 50% relative humidity to prevent microbial growth that causes musty odors.

Regular filter changes

Clogged filters trap odor particles that eventually contaminate the entire system.

Annual preventive cleaning

Regular maintenance prevents the build-up of residues that later become sources of stubborn odours.

Duct sealing

Leaks allow external odors to infiltrate (sewers, damp basements, storage spaces).

Vortex Air anti-odour guarantee

60-day satisfaction guarantee

If odours return within 60 days, we come back free of charge for further treatment.

Certified olfactory test

Our technicians document the entire removal process with olfactory neutrality tests before considering the job finished.

30-day telephone follow-up

We'll call you back a month later to make sure everything's going well and answer any questions you may have.

Estimated disposal costs

Prices depend on several factors:

  • Odor typeOrganic odors are more complex to treat
  • Allocated areaComplete house vs. just a few rooms
  • Contamination intensity: Measured by our specialized detectors
  • Exposure time: The older it is, the more treatment it requires
  • Accessibility: Some pipes are more difficult to treat

On average, odour elimination costs 20-30% more than standard cleaning, but 70% less expensive than to change the whole system.

Questions fréquentes sur l’élimination des odeurs persistantes au Québec

Pourquoi ma maison sent encore mauvais même après un grand ménage complet?

Parce que, dans bien des cas, l’odeur ne vient pas des surfaces visibles. On l’a vu souvent sur le terrain : tout est propre, mais dès que la ventilation démarre, l’odeur revient. Ça veut dire qu’elle est incrustée dans les conduits. Le système agit comme un distributeur d’odeurs et les répand partout, peu importe combien de fois tu laves le plancher.

Comment savoir si l’odeur vient vraiment du système de ventilation?

Un signe clair, c’est quand l’odeur devient plus forte quand le chauffage ou l’air climatisé fonctionne. Autre indice : l’odeur semble venir de plusieurs pièces en même temps. Lors de nos inspections, on découvre souvent des zones humides, de la poussière collée ou des résidus animaux que personne ne soupçonnait avant de regarder dans les conduits.

Quelles sont les odeurs les plus difficiles à éliminer en pratique?

Les pires qu’on rencontre sont l’urine d’animaux, les phéromones de rongeurs, la décomposition animale et la fumée de cigarette ancienne. Ce sont des odeurs qui pénètrent profondément dans les matériaux. Si quelqu’un te promet de régler ça avec un simple parfum, méfie-toi. Ces odeurs-là doivent être neutralisées chimiquement, pas masquées.

Pourquoi les désodorisants et parfums aggravent parfois la situation?

Parce qu’ils ajoutent une couche par-dessus le problème. On arrive souvent dans des maisons où l’air sent un mélange bizarre de parfum artificiel et d’odeur originale. Résultat : ça devient plus lourd, plus étouffant. Tant que la molécule responsable de l’odeur est là, elle finit toujours par ressortir.

Comment identifiez-vous la vraie source de l’odeur avant de traiter?

Ça passe par l’expérience. Une odeur de moisi peut venir d’un conduit mal isolé, d’un bac de condensation ou d’une infiltration invisible. On combine inspection olfactive, caméra et analyse de l’humidité. Traiter sans identifier la source exacte, c’est une des erreurs les plus fréquentes qu’on voit chez les interventions mal faites.

Est-ce que le nettoyage seul suffit pour éliminer les odeurs tenaces?

Non, pas toujours. Le nettoyage enlève les résidus physiques, mais certaines odeurs restent collées aux surfaces. C’est là que les enzymes et les traitements neutralisants entrent en jeu. On a souvent vu des cas où un nettoyage seul améliorait la situation… mais où l’odeur revenait quelques semaines plus tard faute de traitement en profondeur.

L’ozone, est-ce dangereux ou efficace contre les odeurs?

Les deux, selon comment c’est utilisé. L’ozone est très efficace pour oxyder des odeurs que rien d’autre n’élimine, mais seulement quand c’est fait de façon contrôlée, avec des équipements professionnels. Mal utilisé, ça peut créer des problèmes. Bien utilisé, c’est parfois la seule solution qui fonctionne réellement.

Combien de temps ça prend avant de voir un vrai résultat?

Souvent, la différence est immédiate. Dans les cas plus lourds, ça peut prendre quelques heures ou une journée complète. Ce qui compte, c’est la durabilité. Si l’odeur disparaît et ne revient pas, le travail est bien fait. Si elle revient, c’est qu’une source a été oubliée.

Dans quelles situations faut-il agir en urgence?

Après un décès d’animal dans le système, un refoulement d’égouts ou un dégât de fumée, il faut agir vite. Plus on attend, plus les odeurs s’imprègnent profondément dans les conduits. On a vu des cas où un délai de quelques semaines rendait le traitement deux fois plus complexe.

Comment prévenir le retour des odeurs après leur élimination?

Le contrôle de l’humidité est essentiel. Une maison trop humide finit toujours par sentir le moisi. Ensuite, les filtres doivent être changés régulièrement et les conduits étanches. Une petite fuite peut aspirer des odeurs de sous-sol, d’égout ou d’entreposage sans que personne ne s’en rende compte.

Est-ce plus rentable d’éliminer les odeurs ou de remplacer le système?

Dans la majorité des cas, l’élimination professionnelle coûte beaucoup moins cher que de remplacer tout le système. On recommande un remplacement seulement quand les matériaux sont trop endommagés. Souvent, les gens pensent que tout est perdu alors qu’un bon traitement règle le problème pour longtemps.

Comment savoir si l’élimination des odeurs a vraiment été réussie?

Quand l’air devient neutre. Pas parfumé, pas masqué — juste normal. Un bon travail, c’est quand tu oublies qu’il y avait un problème. Et surtout, quand le professionnel reste disponible si une odeur réapparaît, au lieu de disparaître après le paiement.
