Local context

Markham at a glance

Neighbourhoods served: Unionville, Cornell, Cathedraltown, Markville, Berczy Village.

Markham's detached executive homes — especially the ravine-backing lots in Unionville and Cathedraltown — share the same vulnerability: oversized rear glass, low ambient light, and easy back-yard access. York Regional Police data consistently shows these lots as the highest-frequency targets in the area. Clear Guard runs weekly Markham dispatches. Every assessment includes a walk of the full rear of the home — patio doors, kitchen glass, walkouts — before any quote is given. Typical Markham scope: 14 mil film across rear glass, door fortification on front and patio entries, and strike-plate upgrades throughout.

How it has changed

Historical pattern in Markham

Crime patterns are not static. Tracking how forced-entry vectors shift across years lets us scope the right product mix per home — not last decade's threat model.

Markham's residential profile is dominated by 1990s-2010s subdivision builds — Berczy Village, Cathedraltown, Wismer, Cornell — interleaved with older Unionville stock and ravine-backing executive lots near the Rouge. The forced-entry profile across these subdivision streets shares characteristics common to newer Ontario builds: large rear glass walls, deep back yards with limited sightlines from neighbours, attached garages with man-doors into the home. Markham is policed by York Regional Police. YRP publishes break-and-enter data through their crime maps and open data portal. As with any specific stat, period-over-period claims should be cited to that source directly.

What reduces this in Markham

Markham's most common forced-entry profile — large rear glass walls on subdivision homes — is the textbook XPEL Prime XR Security application. The film keeps shattered glass bonded so the smash-and-reach attempt doesn't yield a way in. ARX Guard door fortification adds layered defence on the front and any garage interior man-door — both common secondary vectors when glass is filmed.

Q.01Is home fortification worth it in Markham?
Markham's detached executive-home stock — oversized rear glass, ravine-facing patio doors, mature landscaping that hides back-yard approaches — lines up almost exactly with the vectors York Regional Police lists as highest-risk. Unionville, Cathedraltown and Berczy Village homeowners have been our most common recent Markham clients. Security film on rear glass plus door fortification on front and patio addresses 90%+ of the risk profile.
Q.02How much does security window film cost in Markham?
Most Markham homes we quote fall between $3,000 and $7,000 for a full rear-of-home scope — patio doors, kitchen walkout, family room glass. Pricing is per square foot of glass. Assessment and written quote are free with no obligation.
Q.03Do you service Unionville, Cathedraltown and Berczy Village?
All of Markham — Unionville, Cornell, Cathedraltown, Markville, Berczy Village, Thornhill (Markham-side), Milliken, Greensborough, Wismer, and Angus Glen. We also serve the rest of York Region: Richmond Hill, Vaughan, Aurora, Newmarket.
Q.04My Markham home backs onto a ravine — what should I do first?
Ravine lots are the single highest-risk profile in York Region break-in data. Three priorities, in order: (1) security film on the rear patio door and any oversized rear glass; (2) door fortification on the patio door frame; (3) motion-activated rear lighting. We can usually do 1 and 2 in one visit. Fortifying the rear is the highest-leverage investment you can make on a ravine-backing home.
Q.05How long does a Markham install take?
Most Markham homes are completed in a single day. A full rear-of-home scope runs 8–10 hours with a two-technician crew on larger executive homes. Door fortification adds 60–90 minutes per door. Premium homes with walkout basements may require a second day.
Q.06What's the most common break-in method in Markham?
York Regional Police data for Markham skews heavily toward rear-patio-door forced entry, typically in the 10 p.m. – 2 a.m. window, on homes that back onto ravines, golf courses, or parks. Ground-floor windows in basement walkouts are the second most common. Our standard Markham scope addresses both.
Q.07Do you work with Markham security system companies?
Yes. Security film and door fortification are the physical layer — alarms and cameras are the detection layer. The two complement each other. We coordinate directly with your alarm company if you want sensor placement to match the reinforced glass scope.
Q.08Is your Markham team police-checked?
Yes. Every Clear Guard technician is WSIB-registered and police-checked. The technician at your assessment is the person installing in your home.
Q.09What warranty do you offer in Markham?
10-year manufacturer warranty on XPEL film, parts and labour. Lifetime workmanship warranty on Clear Guard installation. Service calls are handled directly — no deductible, no claims process.
Q.10Do you film large custom homes in Cathedraltown and Angus Glen?
Yes — these are a significant portion of our Markham work. Custom-home glass often includes oversized panels, multi-pane curtain wall, and specialty frames that require adapted film-anchor systems. We spec and install those ourselves.
Q.11Do you do commercial security film for Markham businesses?
Yes. Unionville Main Street storefronts, Markville Mall tenants, Highway 7 corridor retail, and the growing tech-park office stock around Buttonville are regular commercial projects. Anti-smash, anti-graffiti and blast-mitigation spec available.
Q.12Can you come to Markham this week for an assessment?
Usually yes. Our York Region dispatch typically has 48–72 hour availability. For post-incident reinforcement we prioritize same-day wherever possible. Call (416) 907-6900 for urgent scheduling.
Q.13What does XPEL Prime XR Security window film actually do?
It is a high-strength laminate bonded to the interior face of your existing glass. When the glass is struck — by a hammer, brick, crowbar, or boot — the film keeps the shattered shards bonded together. The pane no longer separates, so the hand-through reach an intruder needs simply isn't there. Optically clear, blocks more than 99% UV, compatible with tempered, laminated, single-pane and double-pane residential glass.
Q.14What does the ARX Guard door fortification system include?
A heavy-gauge strike plate anchored with structural screws into the wall framing (not the trim), the multi-point ARX hockey-stick locking system that engages multiple points along the jamb at once, structural reinforcement on both the lock-side and hinge-side jambs, and reinforced hinge plates with longer screws. Tested in our Oakville facility to absorb repeated kick loads that split standard residential door assemblies on the first strike.
Q.15Do I need both products or can I pick one?
Most homes benefit from both. Forced-entry attempts almost always exploit either glass or doors — and often both in sequence. Door fortification stops the kick-in path; window film stops the smash-and-reach path. Doing both gives you layered defence: an attempt fails at the first vector, the intruder either gives up or moves to the second, and the film/fortification on that vector buys the homeowner the same delay. We will scope both during the assessment and give you a written quote with each line itemised.
Q.16Will the film be visible from outside?
No. Most homeowners forget the film is there within a week of install. It is bonded to the inside surface of your existing glass and trimmed close to the frame. Your windows look exactly the same from the street.
Q.17Does ARX Guard work with my smart lock or keypad?
Yes. The ARX Guard system reinforces the framing and strike zone around your existing hardware. Smart locks, keypad locks, and traditional deadbolts all stay in place and continue to work. We are not replacing the lock; we are reinforcing where the door frame fails first under kick force.
Q.18How long does a typical install take?
Most homes are completed in a single day. A typical 10-15 window film install runs 6-8 hours with a two-technician crew. Door fortification adds 60-90 minutes per door. No drywall work, no painting, no door replacement — most customers are back in the house by dinner.
Q.19What is the warranty?
10 years on the XPEL film against bubbling, peeling, and delamination. 10 years on the ARX Guard hardware components. Lifetime workmanship warranty on the installation itself. All warranties are written, transferable on home sale, and honoured directly by Clear Guard — no middleman.
Q.20Can it be installed on tempered or laminated glass?
Both are compatible. We assess each opening on site and spec the right film grade per pane. Some openings benefit from 14-mil interior security film; others from 8-mil interior or 7-mil exterior. The right answer depends on the glass type, the opening size, and the vulnerability profile.
