Job Overview

Location: Toronto, Ontario
Structure: Three-storey Victorian residential home
Problem: Squirrel activity in wall and attic areas
Service: Humane squirrel exclusion and exterior sealing
Visits: Three visits

Summary

Our team completed a multi-visit squirrel exclusion at a tall Victorian home in Toronto after the homeowner reported recurring early-morning and evening noises inside the wall and attic spaces. Inspection confirmed squirrel entry at a rear siding intersection, along with an additional opening being accessed by birds. Humane one-way doors and targeted exterior exclusion were installed, followed by follow-up sealing and final confirmation that all wildlife activity had ceased.

Background / Property Context

The property is a three-storey Victorian-style house with rear access points located along the first- and second-storey elevations above a backyard deck. The structure includes older intersections and layered siding details, which had. All work was completed from the exterior using ladder access, allowing a single technician to safely service the affected areas.

Customer Concern

The homeowner reported hearing consistent scratching and movement sounds in the walls during the early morning hours. The timing and pattern of the noise raised concern about squirrel activity. The homeowner also noted that the sounds appeared to be coming from the rear siding area of the house.

Inspection & Findings

Inspection identified the primary squirrel entry point at a soffit intersection along the rear elevation. Additional gaps were observed along the deck-to-siding transition, creating an open cavity running beneath the siding. Nesting debris and organic material were visible inside the void, consistent with wildlife use. A separate opening was also identified that was being accessed by birds, which rely on pre-existing gaps rather than creating their own entry points.

 

 

Cause Analysis

Older Victorian homes often have complex rooflines and soffit intersections that can shift or separate over time. These features, combined with elevated deck structures, can create concealed horizontal openings that are attractive to squirrels seeking shelter. Once an opening is established, repeated use can widen the gap and allow access to additional wildlife such as birds.

Treatment / Removal

During the first visit, our technician Ardian installed a humane one-way door over the primary squirrel entry point, allowing the animal to exit without re-entry. Galvanized steel mesh was then installed to seal approximately twenty-one feet of exposed cavity along the deck and siding interface. The mesh was fastened securely to prevent future access while maintaining airflow and drainage where required.

Exclusion & Repairs

On the second visit, a follow-up inspection identified additional minor gaps adjacent to the original repair area. These sections were sealed with additional galvanized steel mesh to ensure continuity of the exclusion barrier. All materials were installed flush to the structure and integrated with existing building components to maintain durability.

 

 

 

Outcome & Confirmation

By the third visit, the homeowner reported no further sounds or signs of wildlife activity. The one-way doors were removed, and all exclusion work was reinspected to confirm integrity. No new entry points or animal activity were observed, and the exclusion was considered complete.

Technician Notes

Photos from the site show open cavities beneath the siding prior to repair, nesting material within the void, and completed mesh installations secured along soffit and deck edges. Final images confirm continuous steel mesh coverage and removal of all temporary one-way devices.
