Decontamination Contractor for Commercial, Institutional and Industrial Buildings

One contractor for every contaminant in the building

Since 1999, Demospec has removed asbestos, lead, mold and bird droppings from office buildings, public facilities and industrial sites in Montreal and across Quebec. Our crews handle low-risk and high-risk work, from containment of the work area to material transport and air quality monitoring.

Decontamination Before Renovation, Demolition or Reoccupancy

Clients bring us in for decontamination before a major renovation or deconstruction, after water damage or a disaster, or when bringing a building up to code. Every project starts with the hazardous materials survey and ends with the documentation needed for the next phase of work.
