Identification and permanent sealing of all openings through which wild animals (raccoons, skunks, squirrels, bats) access the building.
The principle: Once the animal is captured and released, its colony or conspecifics often return through the same breaches. Without closure, the extermination is temporary. The closure is the only truly permanent measure.
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
complete exterior inspection (soffits, ridge, roof-wall junction, chimney, ventilation, crawl space), installation of galvanized screens calibrated according to species (12 mm for mice, 25 mm for squirrels, 6 mm for bats), polyurethane caulking of cracks, replacement of ventilation valves with non-return valve models, sealing of pipe passages using expanding foam reinforced with steel wool
Average duration: half a day to a day depending on the surface area and the number of points.
Underwriting and Inspection
Here are the service variants we offer for this need:
- Standard residential house closure (4 to 8 points)
- Full attic with rodent wire mesh
- Commercial or multi-unit building (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
24 months written warranty on sealed points (warranty resumption in case of failure).
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
Questions
How long does the warranty last?
24 months on sealed points. If a point fails during the warranty, we intervene under warranty.
Are the fences visible from the street?
No, they are installed in functional openings (soffits, ventilation, pipe passages) without changing the exterior aesthetics.
Can we do the closure without capturing the animal first?
Not without confirming that the animal is out, otherwise it dies in the building and causes decontamination costs higher than the cost of capture. We coordinate the two steps.
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.

What is the closure of animal entry points?
This service, also known as exclusion, consists of identifying and sealing all openings through which animals enter: cracks, vents, soffits, fascia and pipe penetrations. Our technicians use resistant materials such as wire mesh, caulking and adapted sealants. This is the key to preventing recidivism on the South Shore and in Montérégie.
Why is it essential to close access after an intervention?
Without sealing the openings, rodents, squirrels or raccoons return to the site they already know. The closure of the entry points is therefore the step that makes extermination and decontamination truly sustainable. It transforms the building into a place inaccessible to pests in Longueuil or Brossard.
How do you identify animal entry points?
Our technicians inspect the exterior and vulnerable areas of the building, looking for traces, openings and gnawed materials. An inspection camera can complete the examination in inaccessible places. Each identified access is then sealed with the appropriate material.
What materials do you use to seal openings?
We use wire mesh, steel wool, sealants and resistant plates that animals cannot gnaw on easily. The choice depends on the size of the opening and the species targeted. These durable materials hold up better than simple temporary clogs.
Do you offer a guarantee against any new intrusions?
We aim for sustainable results evaluated on a case-by-case basis, without promising absolute guarantees against future intrusion. A dilapidated or modified building can develop new accesses, which is the responsibility of the owner’s maintenance. Our technicians report fragile areas to be monitored in Chambly or Saint-Bruno.
What is the cost of closing ports of entry?
The price is based on an evaluation, based on the number of openings to be sealed, their access and the materials required. An inspection on the South Shore allows us to quantify the extent of the work. It is a paid service carried out by certified technicians.
