Job Overview

Location: Toronto, Ontario
Structure: Two-story commercial warehouse
Problem: Raccoons entering the roof through damaged exterior openings
Service: Humane raccoon removal and exclusion
Visits: 2

Summary

Our team completed a two-visit humane raccoon removal project at a commercial warehouse in Toronto after raccoons entered the roof assembly through damaged exterior openings. Technician Ardian confirmed the activity, safely removed the dependent young from the ceiling space, installed a one-way door to allow the adult raccoon to exit, and completed structural exclusion using galvanized steel mesh. During the follow-up visit, the one-way door was removed, the remaining opening was permanently sealed, and the exclusion work was confirmed to be effective.

Background / Property Context

The commercial warehouse featured elevated roofline construction with several deteriorated openings along the exterior wall and roof junction. These conditions provided sheltered access into the ceiling cavity where raccoons established a den.

Customer Concern

The property owner reported raccoon activity within the roof area of the warehouse, including noises from the ceiling. They requested a humane solution that would remove the animals while preventing future entry.

Inspection & Findings

Ardian completed a full inspection of the roofline and interior ceiling areas.

The inspection confirmed:

• Active raccoon activity within the roof cavity.
• A primary entry point at the roofline.
• Four dependent baby raccoons located within the ceiling void.
• Several additional structural openings requiring permanent exclusion.

The photographs show damaged ceiling sections that provided access for inspection, dependent young within the nesting area, structural openings along the roofline, galvanized steel mesh installed over vulnerable exterior openings, and a one-way door installed at the primary entry point.

Cause Analysis

Raccoons commonly seek sheltered roof cavities for denning, particularly when exterior construction contains deteriorated openings or gaps near the roofline. Elevated commercial buildings with accessible ledges and structural voids can provide protected entry points. Installing permanent galvanized steel exclusion materials after humane removal helps prevent future wildlife access.

Treatment / Removal

During the initial visit, Ardian confirmed the raccoon activity and completed humane removal procedures.

Work completed included:

• Inspection of the roofline and interior ceiling cavity.
• Installation of a one-way door at the primary raccoon entry point.
• Humane removal of four dependent baby raccoons from the ceiling area.
• Placement of the young outside the structure to allow natural reunification with the adult after it exited through the one-way door.
• Sealing of four additional entry points using galvanized steel mesh.

Exclusion & Repairs

Following confirmation that the raccoons had vacated the structure, our team completed the final exclusion work.

The completed repairs included:

• Removal of the temporary one-way door.
• Permanent sealing of the primary entry point using galvanized steel mesh.
• Inspection of all previously completed exclusion work to verify that the roofline remained fully protected against wildlife entry.

Outcome & Confirmation

During the second visit, no further raccoon activity was reported or observed within the warehouse. The one-way door was removed, the remaining entry point was permanently sealed, and all exclusion repairs were inspected and confirmed secure. The customer was satisfied with the completed service.

Technician Notes

Ardian completed the inspection, humane removal, exclusion work, and follow-up over two scheduled visits. The project successfully resolved the raccoon intrusion while protecting the structure with permanent galvanized steel exclusion materials.
