Don’t Risk Your Health, Because Asbestos is Carcinogenic and Carries High Risks
We are specialists in the decontamination of asbestos-containing insulation. We will solve your problem safely and once and for all.
Does Your Home Contain Asbestos?
Some vermiculite insulation contains asbestos fibres, which are extremely hazardous to your health. If your home was built before 1985, it is very likely that it is insulated with asbestos-containing materials, as they were widely used between 1920 and 1985. These insulations were most commonly sold under the trade name Zonolite Attic Insulation, but also under other names and brands in Canada. Although harmless in their inert state, they become hazardous when cut, degraded or fragmented.
This can happen during renovation or remodeling work, for example. The asbestos fibers are then dispersed in the air. They can then infiltrate the lungs of the occupants and infect them. Simply moving or handling materials can release fibres into the air. These light, highly volatile fibres will remain in the environment. Each time they are moved around the room, they are re-suspended and can be inhaled.

Rodents in Your Attic?
Following the extermination of rodents in your attic, we offer a disinfection and decontamination service to ensure the safety of the occupants. Our decontamination service is at your disposal to advise you on the procedure and products required for decontamination, depending on the type of rodents and the impact of the animal invasion in your home.
Mice and rats are often carriers of diseases. In some cases, these diseases can be transmissible to humans, and can be fatal. For example, the Scots mouse is a carrier of the Hanta virus, sometimes fatal to humans. The rat can transmit several diseases, including plague and rabies. Get more information…
