Replacement of cellulose insulation contaminated by rodents or wildlife, after decontamination of the attic or walls.
The principle: Cellulose insulation (recycled newspaper treated with boron salt) absorbs urine and feces, which gives off lingering odours and can harbour pathogens even after disinfection. Replacement is more effective and less expensive than deep decontamination of existing insulation.
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
industrial vacuum removal of contaminated insulation, bagging and disposal at an approved site, disinfection of bare surfaces, blowing of new cellulose at the regulatory density (minimum R-50 for residential attics in Quebec), checking attic ventilation to prevent recondensation
Average duration: 1 to 2 days depending on the surface area and accessibility.
Underwriting and Inspection
Here are the service variants we offer for this need:
- Cellulose blowing attic 600 to 1,000 sq. ft.
- Removal of contaminated insulation + new blowing (600 sq. ft.)
- Raised wall or floor (on-site 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
10 years on thermal performance according to the manufacturer’s standards.
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 after rodents
- Decontamination after raccoons
- Urethane insulation and technical caulking
- Complete attic decontamination
Questions
Why cellulose rather than fiberglass?
Equivalent thermal performance, but cellulose is more resistant to recolonization by rodents (integrated boron salt, repellent action). Similar cost.
How long does thermal performance last?
25 to 40 years depending on ventilation and settlement. Typical 10-year manufacturer’s warranty.
Does cellulose pose a fire risk?
No. The boron salt treatment gives it a fire resistance rating equivalent to fiberglass.
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: Cellulose Insulation
What is cellulose insulation?
Cellulose insulation is a blown insulation made of treated recycled paper fibers, blown into attics and attics to replenish the removed insulation. It is frequently installed after decontamination to restore the thermal performance of the building. Our technicians install it on the South Shore and in Montérégie.
Why choose cellulose after attic decontamination?
Cellulose fits well in the nooks and crannies of the attic and offers good thermal and acoustic performance at a competitive cost. It is an ecological choice, made of recycled materials, to replace insulation soiled by rodents. This is a common option for homes in Longueuil or Saint-Hubert.
Is cellulose treated against fire and pests?
The cellulose we use is treated with additives that make it fire-resistant and less attractive to certain insects. However, no insulation replaces closing entry points to block rodents. It is part of an approach combining exclusion and sealing.
How is the installation of cellulose insulation carried out?
After decontaminating and preparing the attic, our technicians blow the cellulose with a snowblower until the desired thickness and insulating value are reached. The distribution is adjusted to evenly cover the surface. The product is applied according to the standards in force.
Do you offer a warranty on cellulose insulation?
We aim for a sustainable installation evaluated according to each project, without absolutely guaranteeing all the conditions of the building. A leaky roof, poor ventilation or new animal intrusion can affect the insulation, which is the responsibility of the owner. Our technicians advise you on preliminary corrections.
How much does cellulose insulation cost?
The price is established on the basis of evaluation, depending on the surface area, the desired thickness and the access to the attic. An inspection in Boucherville or elsewhere in Montérégie allows for a fair estimate. It is a paid service carried out by RBQ certified technicians.
