Humane, Guaranteed Squirrel Removal in Markham
Builder-grade roof vents on newer Markham homes are not always built to keep squirrels out, and a determined squirrel can chew through thin vent covers faster than most homeowners expect. We remove them humanely and replace the weak point with something they cannot chew through, so it stays fixed.
Why Squirrels Get Into Even Newer Markham Homes
Squirrels thrive wherever mature trees meet rooflines, and Markham has both in abundance, from the tree-lined streets of Unionville and Markham Village to the newer plantings maturing around Cornell and Buttonville. Properties near the Rouge River and Milne Dam Conservation Park see steady squirrel traffic year round.
Newer subdivisions are not exempt. Standard builder-grade roof vents and soffit material can be thinner than what an older, custom-built home uses, and a squirrel only needs a small weak point to get through. This page is part of wildlife removal in Markham, our hub for every service we offer across the area.

What a Squirrel in the Attic Actually Costs You
This is not just noise overhead. A squirrel gnaws constantly to keep its teeth from overgrowing, and your electrical wiring, wood framing and insulation are all fair game, which is a real fire risk sitting directly above your family.
Every week the animal stays, the nest grows larger and the eventual repair bill climbs with it. A weak vent cover that gets chewed through once will get chewed through again unless it is properly replaced, which is why we treat exclusion as part of our squirrel removal service rather than an afterthought.
Our Squirrel Removal Process
Every Markham property is different, so we tailor the process to what we find during inspection. Here is what you can expect when you contact us for our squirrel removal service.
Inspection
We examine your roofline, attic, soffits and vents to confirm how the squirrel entered and whether young are present.
Humane Removal
We remove the animal using a humane method suited to the location, often a one-way door that lets it exit on its own. We follow MNRF guidelines for humane squirrel handling and exclusion in Ontario.
Exclusion & Proofing
We seal the entry point with durable materials so another squirrel cannot chew through or use the same opening again.
Cleanup & Restoration
We remove contaminated insulation and nesting material, then disinfect the area to restore your attic to a safe condition.
Neighbourhoods We Serve in Markham
We serve homeowners across Markham, and if raccoons are also getting into your property, ask about our raccoon removal in Markham service as well.
Unionville
Unionville's historic core sits close to Milne Dam Conservation Park, and the mature tree cover there puts squirrels within easy jumping distance of older rooflines, where a warped vent cover is often easier to work loose.
Markham Village
The established streets of Markham Village have generations-old trees that put squirrels right at roof height, and older vent screens here can wear thin enough for a persistent squirrel to chew through.
Cornell
Cornell's newer builds near the Rouge River corridor use standard builder-grade vent covers, and squirrels test these thinner materials just as readily as they test older screening elsewhere.
Buttonville
Buttonville's mix of newer subdivisions gives squirrels plenty of tree cover to stage from, and homeowners are often surprised how quickly a squirrel can chew through a stock plastic vent cap.
Milliken
Milliken's dense residential streets sit close enough to local parkland that squirrels regularly test soffits and gable vents, chewing at any seam that has started to loosen.
Thornhill (Markham side)
On the Markham side of Thornhill, mature neighbourhoods back onto ravines and green corridors that give squirrels an easy route toward an unguarded roof vent.
Cathedraltown
Cathedraltown's newer construction still relies on standard vent materials, and a squirrel does not need much more than a soft plastic cap to find its way into an attic.

Frequently Asked Questions
How much does squirrel removal cost in Markham?
The cost depends on how many entry points there are, how much attic cleanup is needed, and whether the vent or soffit material needs full replacement rather than a simple patch. A single sealed roof vent is priced differently than a job involving chewed-through builder-grade material across multiple points. We provide a clear quote after inspecting your property so there are no surprises.
Is squirrel removal regulated in Ontario?
Yes. Ontario’s Fish and Wildlife Conservation Act requires humane handling of squirrels, and MNRF guidelines govern how these animals are excluded and, where applicable, relocated. Our technicians follow these rules on every job, which is why exclusion with a one-way door is our standard approach.
How long does squirrel removal take in Markham?
Once a one-way exclusion door is installed at the entry point, most squirrels leave within a few days on their own schedule. We then confirm the attic is clear before sealing the opening permanently with material the animal cannot chew through. Cleanup and restoration can add extra time depending on how much insulation and nesting material needs to be removed.
Why should I deal with a squirrel in the attic quickly?
A squirrel gnaws constantly to manage its teeth, and left alone it will keep working at wiring, framing and insulation, which raises real fire risk the longer it continues. A chewed-through vent or soffit rarely holds on its own and tends to get reused by the same or another squirrel. Acting quickly keeps the damage smaller and the repair simpler.
Protect Your Markham Property Today
A squirrel working at a vent cover near Cornell or Cathedraltown will not stop until it gets through, and once it does, the same weak point tends to get reused unless it is properly repaired. Our licensed technicians respond quickly across Markham, from Unionville to Milliken, with a clear inspection and honest pricing before any work begins.
