Closure of outdoor access points

Mouse protection

An Essential Preventive Method to Block Rodent Invasions

Mouse can enter your home through openings as small as a dime. That’s why sealing off exterior access points is one of the most effective ways to prevent infestations before they even begin.

A Physical Barrier Against Intrusions

Rodents are attracted to warmth and food. By sealing exterior joints and openings, you eliminate the main entry points they use to get inside.

This approach allows you to:

$
Protect the structure of your house
$
Reduce the risk of contamination and damage
$
Avoid repeated use of chemical treatments
$
Prevent seasonal infestations, especially in autumn and winter

Critical areas targeted during intervention

Our interventions focus on high-risk areas, particularly at material junctions:

$
Brick / soffit
$
Foundation / cladding (vinyl, aluminum, CanExel)
$
Other transition zones or visible cracks
Each point is precisely assessed to determine the most suitable sealing or filtration technique.

Ventilation maintained through custom installations

Some openings are necessary for building ventilation. In these cases, we install a sturdy metal mesh that:

Allow air to circulate freely
Completely blocks access for rodents
Resistant to corrosion and weathering
Preserves the appearance of your coating

Robust Sealing for Unventilated Areas

When ventilation is not required, we use a professional-grade exterior sealant:

DOWSIL™ Contractor Paintable Sealant, a durable product designed to withstand Quebec winters.

Its advantages:

$
Resistance to cracking and moisture
$
Superior resistance to temperature variations
$
Clean, uniform and aesthetically pleasing finish
$
Warranty up to 25 years
$
Can be painted to match your flooring

Protecting Brick Ventilation Joints (Weep Holes)

Weep holes are important for the breathability of brick walls, but they are also a target for mice.

We install high-grade copper insulation which:

$
Do not rust
$
Resists rodent intrusion
$
It blends visually into the masonry
$
Maintains the wall’s natural ventilation

Complete Inspection and Treatment of All Risk Areas

Each intervention includes a thorough inspection of your building to detect and secure other vulnerable areas, such as: electrical wire and cable penetrations, penetrations related to a heat pump or heating system, exterior electrical outlets and wall lights, and visible cracks or holes around the foundation.

Each of these areas is treated with the appropriate material to ensure long-lasting and aesthetically pleasing protection against mice.
