Controlled demolition and safe disposal of materials heavily contaminated by pests (urine-soaked floors, moldy gypsum, clumped insulation, damaged framing).
The principle: Some damage goes beyond what simple decontamination can recover: encrusted odor, compromised structure, persistent biological contamination. Partial demolition eliminates the source and allows reconstruction on a sound basis.
Nova Extermination provides this service on the South Shore with RBQ 5734 75930 01 license and a warranty adapted to the case. All our work complies with CNESST standards for the protection of occupants and technicians.
Our method
preliminary assessment and costing, installation of polyethylene barriers to confine the area, manual or mechanical demolition depending on the surface (gypsum, floors, panelling), bagging of debris in approved disposable bags, transport to an authorised landfill site, final disinfection before reconstruction
Average duration: 1 to 3 days depending on the magnitude.
Underwriting and Inspection
Here are the service variants we offer for this need:
- Partial demolition (contaminated floor 100 sq. ft.)
- Complete room (gypsum + floor + insulation)
- Entire Accommodation (Extreme Cases, Quote)
What influences the quote
- Surface or volume to be treated
- Extent of the infestation or situation
- Accessibility of the areas concerned
- Response time requested (planned or emergency)
- Scope of the desired warranty
- Documentation required for insurer, notary or audit
The inspection is non-binding. We evaluate on site (or by phone as the case may be) and give you a written estimate adapted to your building before any work begins. No unpleasant surprises at the end.
Warranty and certifications
Complete documentation for insurer, certificate of transport to the approved site, written guarantee on the health of the surface delivered.
Why entrust this service to a pest control specialist rather than a general contractor:
- Specialization: we know where to look, what to seal and what doesn’t need to be sealed (saving on the quote)
- Coordination: if an infestation is still active, our technicians intervene before the work, without calling on a second service provider
- Double guarantee: on the work AND on the non-recurrence of the pest
Services that are often combined with it
- decontamination
- Cleaning up after death
- cleaning of unsanitary housing
- Complete attic decontamination
Questions
When is demolition really necessary?
When the biological contamination has reached the structural materials (framework, soaked insulation) and surface decontamination is not enough. Our report documents the justification for your insurer.
Is reconstruction included?
No, but we work with partner contractors on the South Shore who intervene quickly after our visit.
Is transport on an approved site documented?
Yes. Certificate of Deposit at Authorized Site, required for insurance claims and meets provincial standards.
Is the quote non-binding?
Yes, the preliminary assessment and written quote are non-binding.
Coverage by home insurance?
Depending on the initial cause, yes in many cases. We provide the necessary documentation for the claim.

Frequently Asked Questions: Contaminated Demolition
What is the demolition of contaminated materials?
This service consists of the controlled removal and demolition of unrecoverable materials (gypsum, insulation, wood) soiled by feces, urine or mould following an infestation. Debris is bagged and safely disposed of prior to site cleanup. Our technicians work on the South Shore and in Montérégie.
When does contaminated demolition become necessary?
It is necessary when materials are too soaked or degraded to simply be cleaned and disinfected, for example an insulation full of urine or a wall overgrown with mold. It is also used when the contamination has penetrated deep into the structure. An inspection determines what needs to be demolished in Longueuil or Brossard.
How do you deal with debris and contaminated dust?
We confine the work area to limit the dispersion of dust and contaminants to the rest of the building. The debris is bagged, transported and disposed of according to the rules in force, then the remaining surfaces are disinfected. Our technicians wear the protective equipment required by the CNESST.
What happens after the contaminated sections are demolished?
Once the materials have been removed, we disinfect the exposed structure and can coordinate the restoration (insulation, partitions). This step sanitizes the premises before any reconstruction to avoid closing off surfaces that are still contaminated. Each project is evaluated on a case-by-case basis in Saint-Hubert or Sainte-Julie.
Do you offer a warranty on contaminated demolition?
We aim for sustainable sanitation assessed according to each situation, without absolutely guaranteeing all the work. We do not take care of the overall dilapidation or insalubrity of a poorly maintained building beyond the treated sections. Our technicians will tell you the exact scope of the intervention.
What is the cost of demolition of contaminated materials?
The price is based on an evaluation, based on the volume of material to be demolished, access and the degree of contamination. An inspection in Montérégie allows you to calculate the extent of the work with precision. It is a paid service carried out by RBQ certified technicians.
