What to do if you suspect contamination or infection

If you discover or suspect the presence of viruses, bacteria or mould, act with caution and call in the professionals.

Seal off the area: Block access to any space where contamination is suspected or confirmed.

Follow Public Health guidelines: Follow the latest isolation and personal safety guidelines issued by the authorities.

Call Qualinet: Contact us right away to schedule a professional disinfection of your property.


Whatever you do, do not clean it yourself! Disturbing mould releases harmful spores into the air. Never scrub affected surfaces without the proper protective gear.

Contain the affected area: Keep doors closed and seal off the space to prevent spores from drifting into other rooms.

Contact Qualinet for a consultation: Talk to us before you touch anything. Visible mould is often just the tip of the iceberg.


Never enter a contaminated area without proper personal protective equipment (PPE), including an N95 mask, gloves, eye protection, etc.

Check with your insurer to see if your policy covers professional decontamination for mould or hidden water damage.


Asbestos and mermiculite removal

Why is asbestos dangerous?

Asbestos is a fibrous mineral that was widely used in Quebec’s construction industry, particularly for its insulating and fire-resistant properties. Although its use has been banned across Canada for several years, it can still be found in many older homes as well as in commercial and industrial buildings. Asbestos fibers may be present in insulation, fireproof panels, certain floor coverings, and various wall or ceiling tiles. Inhaling these fibers is associated with serious illnesses such as asbestosis, mesothelioma, and certain types of cancer.

A standardized safety protocol must be followed for its removal and disposal. You should never attempt to remove asbestos-containing materials yourself. When in doubt, refrain from handling it and contact Qualinet for professional guidance.

Vermiculite – an insulation material still found in Quebec

Utilisée surtout entre les années 1950 et 1980, la vermiculite servait couramment à isoler les entretoits (greniers). Plusieurs sources de vermiculite contiennent des fibres d’amiante, ce qui représente un risque pour la santé. Sa présence peut également entraîner une perte de valeur de la propriété et causer des coûts supplémentaires lors de travaux de rénovation.

We continuously monitor guidelines issued by various authorities (Health Canada, public health agencies and other dedicated organizations) to ensure our protocols meet the highest standards of effectiveness.


e locate the source of the problem—often linked to moisture, poor ventilation or the aftermath of a disaster. We offer a free, no-obligation inspection of your attic to check for hidden mould, which is commonly caused by inadequate ventilation.


Once mould is found, our specialized teams remove it safely using the appropriate PPE and containment techniques to prevent cross-contamination.


To prevent mould from returning, particularly in the attic, we provide optimized ventilation solutions. Proper airflow increases your comfort, extends the life of your roof shingles (preserving manufacturer warranties) and saves you money on heating and cooling costs.

Decontamination and mould: Frequently asked questions

Is mould actually dangerous?

YES. According to Health Canada, mould growth is a serious health hazard that can lead to chronic respiratory issues and severe allergies.

Can I get rid of the mould myself?

We don’t recommend it. Without specialized equipment, you risk inhaling spores and making the problem worse by spreading them. Better call Qualinet instead.

Why does my mould keep coming back?

Usually, it’s because the root cause (like a hidden leak or poor ventilation) was never fixed. Qualinet treats the cause, not just the symptoms.

Is my attic at risk?

A staggering number of Quebec homes suffer from poor attic ventilation. Contact us for a free inspection.

Does my insurance cover viral decontamination?

Coverage varies from one policy to the next. Check yours for specific clauses on biological risks and pandemics.
