The attic is often the first place colonized by rodents and wildlife, and its insulation is the first to be soiled or destroyed. Nova Extermination’s attic insulation service restores sound and efficient insulation, generally following decontamination, throughout the South Shore of Montreal and Montérégie.
Why redo your attic insulation
Insulation contaminated with urine and feces loses its insulating value, retains odours and becomes a breeding ground for bacteria. Squirrels, raccoons and mice also move the material, creating cold zones. Re-insulating after the soiled insulation has been removed restores the comfort and energy efficiency of the building.
Isolation and pest prevention
Putting insulation back on without closing the accesses doesn’t solve anything: the animals come back. That’s why we combine insulation with exclusion, i.e. the sealing of soffits, vents and entry points, for a lasting result. In Longueuil, Saint-Hubert or Chambly, this combined approach protects your attic for the long term.
Cellulose or urethane?
We install blown cellulose insulation (recycled fibers, good performance, ecological) or spray urethane foam (excellent insulating value and airtightness that seals cracks). The choice depends on the attic configuration and your goals; Our technician will advise you on the most suitable option.
Our service
After sanitizing and preparing the attic, we blow or project the insulation according to the standards in force, up to the targeted insulating value. Nova Extermination is a certified company (RBQ, CNESST) that uses approved products.

Frequently Asked Questions: Attic Insulation
Why redo attic insulation after an infestation?
Insulation soiled by urine and rodent or animal feces loses its effectiveness and retains odors and contaminants. Removing it and then reinstalling new insulation restores energy efficiency and a healthy environment, especially on the South Shore where attics are often targeted.
Does attic insulation prevent pets from returning?
Isolation alone is not enough: without closing the entry points, the animals come back. We therefore combine the installation of insulation with exclusion (soffits, vents, sealed openings) for a lasting result on a case-by-case basis in Longueuil or Boucherville.
Is it better to choose cellulose or urethane for the attic?
Blown cellulose offers good performance at a competitive cost and an environmentally friendly choice, while spray urethane provides excellent insulating value and seals cracks. The best choice depends on the configuration of the attic; Our technician will guide you according to your situation.
Does attic insulation improve my heating bill?
Yes, a well-insulated attic significantly reduces heat loss through the roof, one of the main areas of loss in a house. Comfort improves in summer and winter, in addition to restoring a healthy attic after an infestation.
How much does attic insulation cost?
The price is based on an evaluation, based on the surface area of the attic, the thickness of insulation targeted, the possible removal of the old insulation and access to the premises. An inspection in Montérégie allows for a fair estimate. It is a paid service carried out by RBQ certified technicians.
Do you offer a warranty on insulation?
We aim for a sustainable and compliant 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.
