Anti-mouse and pest caulking service
Did you know that a mouse can enter a hole as small as a 10-cent coin, while a rat can enter a hole the size of a 25-cent coin? Very small, isn’t it? And above all, it is not easy to spot. The solution? The mouse caulking of your home! It is difficult to get rid of a rodent if the source of infiltration is not blocked or clogged. Our mouse caulking service is a complete solution to permanently remedy your infestation problem.
The junction between the roof and the exterior wall of the house is where unwanted visits most often seep in. Indeed, sometimes a hollow forms there, and the mice only have to climb on the brick to get there quite easily. They also manage to enter the house through the chimney or ventilation dampers. Door sills and roofs are also places to which attention must be paid.
Here are the other animals that get into the holes in your home:
- Birds
- Bat
- Flying insects (wasps, hornets, etc.)
- Crawling insects (ants, cockroaches, spiders)
- Rats Field Mice
Identify sources of infiltration
It is difficult to get rid of a rodent if the source of infiltration is not blocked, clogged or caulked. Our mouse or rat hole caulking service is a complete solution to permanently remedy your infestation problem.
Mouse caulking
Once these flaws have been spotted and the undesirables have been exterminated, it is time to caulk against mice and pests of windows and doors as well as any other holes reported. However, we suggest that you repair an opening as soon as you spot it as a preventive measure. Have any cracks and openings repaired before it’s too late. A simple little hole could get you in a lot of trouble! At Nova Extermination, we have the necessary solutions to caulk the flaws, and solve your infestation problem once and for all.
Where we come in when we talk about caulking
The bulk of our caulking operations are concentrated in the immediate corridor of the South Shore. In Longueuil (Vieux-Longueuil), it is mainly the triplexes of Vieux-Longueuil and the bungalows of Saint-Hubert that occupy us: stone foundations, poorly jointed soffits, staggered dormers. In Brossard and the surrounding area, alphabetical perimeters A to R require systematic sealing of dryer ducts and exterior plumbing entrances. Our comprehensive caulking offer on the South Shore covers the entire MRC territory, with a particular intensity in the intermediate suburbs. In Boucherville and its residential neighbourhoods, Old Boucherville and the edges of Parc national des Îles produce a steady stream of interventions on heritage soffits. Further east, caulking in Saint-Jean-sur-Richelieu is heavily affecting Old Saint-Jean and Iberville, where the brick foundations have aged. Finally, our technicians regularly travel to Saint-Hyacinthe and surrounding areas for multi-unit dwellings in the Saint-Joseph sector and farmhouses on the edge of the farm.
Pest Caulking Methodology: Steps and Materials
Effective caulking is not just about plugging a few holes: it follows a strict sequence of inspection, mapping of entry points and sealing with materials adapted to each gap. Our technicians always start with a complete diagnosis of the external perimeter of the building, starting from the ground and working up to the roof. Every sensitive junction is documented: pipe penetrations, soffits, dryer ducts, air intakes, foundation joints, dormers, concrete slabs and flashings. Mice can pass through a 6 mm hole, and crawling insects exploit cracks less than 2 mm. That’s why we map each opening accurately before choosing the right material.
The choice of material depends on the type of opening and the use of the area. For utility passages (pipes, electrical wires), we use stainless steel wool combined with a polyurethane sealant that is resistant to rodent chewing. For foundation cracks, a fast-setting hydraulic mortar is preferred. The soffits and roof-wall junctions are fitted with a galvanised wire mesh of at least 6 mm, mechanically fixed and caulked with a neutral silicone sealant. The basement windows and ventilation ducts are protected by screwed stainless steel grids, never simply glued. All of our materials meet the standards of the National Building Code of Canada and CMHC recommendations for the thermal envelope.

|---|---|---|---|---|
| Staggered Vinyl Soffit | 5 to 25 mm | Galvanized Trellis 6 mm + Sealant | Mouse, Squirrels, Bats | 10 to 15 years |

Caulking: pricing and duration of intervention
In Quebec, a complete anti-pest caulking on a single-family home is based on evaluation, depending on the size of the perimeter and the number of entry points identified. A duplex or triplex in a dense urban area (Plateau, Vieux-Longueuil, Vieux-Saint-Lambert) varies on evaluation, due to the complexity of the multiple soffits and stone foundations. A condominium or a commercial building is subject to a specific estimate after inspection. The intervention typically lasts between 4 and 9 hours for a standard house, and between 1 and 3 days for multi-unit buildings. All our work complies with CNESST safety protocols, particularly for working at height and the use of articulated ladders above 3 meters. Depending on the case, we can provide a before/after photographic report and a guarantee on the treated areas.
Did you know?
Mice leave odors so that other mice know where to find them. This is why an infestation problem will return, even if the mice are exterminated. That’s why finding and caulking the entry points against mice is important!

Frequently Asked Questions: Caulking
What is the rodent and insect caulking service?
Caulking consists of sealing cracks, joints and small openings through which rodents and insects infiltrate a building. We use durable sealants and materials around windows, doors, pipes and foundations. It is a preventive exclusion measure offered on the South Shore and in Montérégie.
How does caulking help prevent infestations?
By sealing the gaps, caulking deprives pests of the access routes they use to enter and nest. A mouse can squeeze through an opening the size of a coin, which is why it’s important to seal even small cracks. This prevention reduces the risk of infestation in Longueuil or Chambly.
Which areas of the building are caulked first?
We target window and door surrounds, pipe and wire penetrations, foundation cracks and material junctions. These points are the most likely to let rodents and insects in. An inspection identifies vulnerable areas in Saint-Hubert or Boucherville.
What materials do you use for caulking?
We use suitable sealants and, for larger openings, resistant materials such as steel wool or wire mesh that rodents cannot chew on. The choice depends on the location and the type of pest. These durable materials provide a more reliable seal than a simple temporary plug.
Does caulking ensure that no pests will enter?
We aim for sustainable results evaluated on a case-by-case basis, without promising an absolute guarantee, because a building evolves and new cracks can appear. Regular maintenance of the building remains the responsibility of the owner. Our technicians indicate the areas to be monitored after the intervention.
How much does a caulking service cost?
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 you to estimate the cost of the work. It is a paid service carried out by certified technicians.
