Detailed Description

If Mice Are Getting Into Your Toronto & GTA Home, They’re Using Entry Points You Haven’t Found Yet

A mouse can enter a Toronto & GTA home through a gap as small as 6mm — about the diameter of a pen. Solving a mouse problem with traps and bait alone addresses the population inside your Toronto & GTA home but doesn’t prevent new mice from entering through the same gaps the original animals used. In Toronto & GTA’s falls and winters, as temperatures drop, new mice are continuously seeking warm entry points. Without sealing those entry points, the problem repeats itself seasonally regardless of how much trapping is done inside.

At CNG Contracting, rodent-proofing inspection in Toronto & GTA is a systematic exterior assessment of your property identifying every potential entry point — not just the obvious ones. The goal is a written record of every gap, penetration, and weakness in the building envelope that represents a mouse or rodent access point, with specific recommended actions for each. This is the diagnostic step that makes exclusion work instead of just managing the symptom.

What the Rodent-Proof Inspection Covers in Toronto & GTA

  • Foundation Perimeter: The foundation-to-sill plate junction, utility penetrations, foundation cracks, and weep holes in brick veneer — the primary rodent entry zone in most Toronto & GTA homes
  • Garage: Garage door bottom seal condition, gaps at side jambs, utility penetrations through garage walls, and gaps at the garage-to-home connection
  • Roofline: Gaps at fascia/soffit junctions, roof vent covers, and any attic access points accessible from the exterior
  • Utility Penetrations: Every pipe, conduit, and cable entry through the exterior of your Toronto & GTA home — often unsealed or with deteriorated sealant that no longer fills the gap effectively
  • Written Report: A complete document describing every entry point found, the recommended sealing method, and priority level — so you have a clear action plan for your Toronto & GTA property

Frequently Asked — Rodent Proofing in Toronto & GTA

Can you do the sealing at the same visit as the inspection in Toronto & GTA?

Often yes — we can combine the inspection and sealing work in a single visit for most Toronto & GTA homes. The inspection scope is separate from the sealing scope and priced accordingly, but scheduling both in a single visit is the most efficient approach when the inspection indicates immediate sealing work.

Do I need pest control and rodent-proofing or just one of them?

For most Toronto & GTA homes with an active mouse problem, both are beneficial in sequence — pest control reduces the existing population, exclusion (sealing) prevents new entry. Exclusion without pest control may leave existing mice inside. Pest control without exclusion solves the current population but allows the problem to recur.

How do I book a rodent inspection in Toronto & GTA?
