Pest-Proof Sealing
Detailed Description
Mice and Insects Enter Toronto & GTA Homes Through Gaps You Haven’t Found Yet
A mouse can enter a Toronto & GTA home through a gap the size of a pen cap — approximately 6mm. Carpenter ants, earwigs, and spiders have even lower access requirements. In Toronto & GTA’s climate, where temperatures drop in fall and small rodents and insects seek warmth, the gaps around utility penetrations, foundation cracks, door thresholds, and weathered exterior caulk joints are active entry points that standard pest control doesn’t address. Extermination and trapping deal with what’s already inside. Exclusion — sealing the entry points — stops the problem at the source.
At CNG Contracting, pest-proof sealing in Toronto & GTA is a systematic inspection of the exterior of your home for all potential entry points — utility penetrations, foundation gaps, weep holes, gaps at fascia and soffit junctions, door and window perimeter failures — and proper sealing of each with the correct material for the location and the pest being excluded. Steel wool and hardware cloth for rodent exclusion. Foam sealant for utility penetrations. Caulk for surface gaps. The right product at the right location.
What Pest-Proof Sealing Involves in Toronto & GTA Homes
- Exterior Perimeter Inspection: Systematic review of the full exterior of your Toronto & GTA home looking for gaps at grade, utility penetrations, foundation-to-sill junctions, and all other potential entry points.
- Material-Appropriate Sealing: Rodents can chew through foam and caulk — rodent exclusion uses stainless steel wool, hardware cloth, or copper mesh as the barrier with sealant over top. Foam alone at rodent entry points is not adequate.
- Utility Penetrations: Plumbing, electrical, and HVAC penetrations through the foundation and exterior walls of Toronto & GTA homes are among the most commonly overlooked entry points — we seal each one we find.
- Written Summary: Every entry point found and method used to seal it is documented — so you have a record of what was done at your Toronto & GTA property.
Where Pests Most Commonly Enter Toronto & GTA Homes
- Foundation-to-sill plate junction — the horizontal gap at the base of all wood-framed Toronto & GTA homes
- Utility penetrations — plumbing, electrical conduit, gas line, and HVAC through the foundation and walls
- Garage door bottom seals that have failed or compressed flat
- Weep holes in brick veneer — required for moisture drainage but also entry points
- Soffit and fascia gaps where deterioration has created access to the attic
Pest-proof sealing in your Toronto & GTA home addresses the entry points that bring pests inside — permanently, rather than managing them after they’re in. Book your visit today.

Frequently Asked — Pest Exclusion in Toronto & GTA
Does pest-proof sealing replace pest control in a Toronto & GTA home?
They work together. Exclusion stops new entry. Existing pests already inside need to be addressed separately — we advise on the appropriate sequence (exclusion typically after interior pest population is reduced, to avoid trapping pests inside walls). We’re happy to discuss the right order for your specific Toronto & GTA situation.
Can you seal weep holes in brick veneer without blocking moisture drainage?
Yes — weep holes require a balance between pest exclusion and moisture drainage. We use stainless steel weep hole covers or mesh inserts that allow moisture to exit while blocking rodent access — not solid plugs that would trap moisture behind the brick veneer of your Toronto & GTA home.

Why is a Technical Visit necessary?
Pests are persistent. A mouse can squeeze through a hole the size of a dime, and simple spray foam isn't enough because they can chew right through it. Our Pest-Proof Sealing assessment identifies overlooked entry points—like AC lines, gas pipes, and foundation cracks—and determines the right combination of materials (steel wool, copper mesh, and elastomeric sealant) to create a permanent barrier.
