Final cost depends on severity, property size, and treatment method.
Markham has two pest realities separated by about 30 years of construction. Walk down Main Street Unionville and the heritage homes there have fieldstone foundations with gaps that mice have been using since before the town had a traffic light. Drive 15 minutes north to Cornell or Box Grove and the brand-new detached homes are already getting mice through settling gaps around gas lines and dryer vents — the foundation shifts in the first two winters and opens up entry points the builder never sealed. The Rouge River cuts through eastern Markham and delivers raccoons, skunks, and squirrels right into the backyards along Rouge River Estates. Milliken is rat territory — the dense mix of restaurants and food businesses along Steeles and McCowan feeds Norway rat populations that burrow under adjacent residential foundations. Angus Glen looks pristine, but the golf course is raccoon habitat and they do not stay on the fairways.
Our Raccoon Removal Process in Markham
Inspection
The technician walks the entire roofline checking soffits, roof vents, plumbing stacks, and fascia boards. Raccoons leave greasy rub marks and claw scratches at their entry points. If the activity is in spring, the technician confirms whether kits are present before any exclusion work begins.
Treatment
A one-way exclusion door goes over the active entry point. The raccoon pushes out to forage at night but cannot get back in. If babies are present (March–June), the technician waits until they are mobile enough to follow the mother out. This takes patience — typically 2–3 weeks extra during baby season.
Prevention
Once the raccoon is confirmed out (3–7 days after door installation), every vulnerable point on the roof gets sealed with 16-gauge galvanized steel mesh bolted into the structure. This includes soffit junctions, roof vents, plumbing stacks, and any weak fascia. Attic cleanup with decontamination follows.
Signs You Need Raccoon Removal in Markham
-
Heavy thumping in the attic between 10 PM and 5 AM — raccoons are nocturnal and loud
-
Torn or peeled-back aluminum soffit panels, especially at roof junctions
-
Greasy, dark smudge marks around roof vents or soffit edges where raccoons climb in
-
Droppings on the roof, in the attic, or piled on a flat surface like a deck (raccoon latrines)
-
A strong ammonia or musk smell coming from the attic, worst on warm days
Why Hire a Professional in Markham
-
Ontario law requires humane removal — one-way doors, no relocation past 1 km. A licensed operator knows the rules and the fines for breaking them.
-
Sealing a hole while babies are inside leads to dead animals in your attic, thousands in damage, and a smell that lasts months. Pros know how to check.
-
Raccoons can carry rabies and their droppings contain roundworm eggs. Proper PPE and decontamination are not optional.
-
Aluminum flashing and expanding foam do not stop raccoons. Only 16-gauge galvanized steel mesh bolted to the structure holds up long term.
-
A proper exclusion job comes with a warranty — usually 1–2 years. If the raccoon gets back in, the company comes back at no charge.
