Before demolition
Why assess decontamination before demolishing?
Before demolishing a building constructed before 1990, you need to know what is in the walls.
Asbestos, mold and lead paint are not visible to the naked eye, but they represent serious health risks for workers and occupants.
We do not perform decontamination ourselves: this work requires specific certifications separate from the RBQ demolition license.
What we do is coordinate the entire process with CNESST-certified specialized companies, from the initial assessment through to certification of the decontaminated area.
You have a single point of contact for the whole sequence: assessment, decontamination by the certified company, then demolition. No friction, no coordination for you to manage.
Who it's for
Residential and commercial decontamination coordination in Montreal
We coordinate decontamination for homeowners, general contractors and building managers who need to prepare or secure their site before work begins.

Which contaminants do we handle?
Why it's mandatory
Why is decontamination mandatory?
CNESST imposes clear obligations on contractors working in buildings that may contain hazardous materials. The consequences of non-compliance are severe.
Health of workers and occupants
Asbestos exposure causes mesothelioma and other lung cancers. Mold causes serious respiratory issues. CNESST protects workers through strict exposure standards.
CNESST legal obligations
Working in a contaminated area without prior decontamination is a violation of the Act respecting occupational health and safety. Fines can reach tens of thousands of dollars, in addition to an immediate work stoppage.
Work stoppages and added costs
Discovering asbestos mid-demolition halts the site immediately and creates unpredictable costs. A prior assessment avoids this by planning decontamination before work begins.
Resale value
A building certified free of hazardous materials sells more easily and at a better price. Decontamination documentation is an asset in a real estate transaction.
Our approach
We coordinate. Certified experts execute.
If asbestos is suspected, we stop everything. CNESST regulations are clear on this and we don't compromise on the safety of workers or occupants.

Network of CNESST-certified companies
We work with decontamination companies that hold the specific certifications for asbestos, mold and lead removal under CNESST protocols.
A single point of contact for the whole sequence
Assessment, decontamination and demolition: you don't have to manage multiple companies and multiple schedules. We coordinate every step.
Certification before resuming work
We never resume demolition work before receiving written certification from the decontamination company confirming that the area is secure.
Complete documentation
Analysis reports, decontamination certification, disposal records: every document is provided to the client for their property file.
How it works
The decontamination process we coordinate
We manage every step so you don't have to coordinate multiple companies.
Prior assessment (2 to 4 days in lab)
We refer you to a certified assessor who takes the necessary samples. The samples are analyzed in a laboratory. Analysis time: 2 to 4 business days.
Coordination with the decontamination company
If contaminants are confirmed, we contact a CNESST-certified company, prepare the schedule and coordinate site access.
Certified decontamination (1 to 7 days depending on contamination)
The specialized company carries out the decontamination work according to CNESST protocols. A small residential area: 1 to 3 days. More extensive contamination: 3 to 7 business days or more.
Certification and resumption of work
The decontamination company issues written certification confirming that the area is secure. We receive this document before resuming demolition work.
Demolition and removal
Once the area is certified secure, we proceed with demolition according to the original plan. Debris is removed to certified sorting centres.
