Serving Toronto

From downtown condos to century homes in the older east and west end neighbourhoods, Toronto properties bring a wide range of electrical challenges: aging knob-and-tube wiring, undersized panels, and condo board requirements for EV charger installations. Our licensed electricians work across the city, providing code-compliant electrical service for homeowners, landlords, and businesses alike.

In older pockets like The Annex, Riverdale, and High Park, the most common calls we get are knob-and-tube and aluminum wiring assessments, panel upgrades ahead of a renovation, and insurance-driven electrical inspections during a home sale or refinance. In denser areas like Yorkville and downtown condo corridors, the work skews toward in-suite troubleshooting, lighting upgrades, and condo board–approved EV charger installations in shared parking garages. In The Beaches and Leslieville, potlight and backyard lighting installs are common alongside general panel and outlet work in century homes.

We regularly work in:The Annex,Leslieville,The Beaches,High Park,Riverdale,Yorkville, and the rest of Toronto.

Security Alarm Installation in Toronto: What to Expect

In The Annex, Riverdale, and High Park, most of our alarm calls are on century homes with a half-dozen or more original window openings plus a back and basement entry point, so the panel work is mostly about zoning enough door/window contacts and motion coverage for a house that wasn’t built with security wiring in mind — running new low-voltage cable through plaster-and-lath walls takes more care than a stud-and-drywall job. Downtown and Yorkville condo towers are the opposite problem: the building already has fob access and lobby cameras, so an in-suite alarm is usually just a keypad, a glass-break sensor for the balcony door, and maybe a motion sensor for the entry hall, not a full perimeter system. We also get a steady stream of calls from landlords converting older Leslieville and Beaches houses into legal duplexes or triplexes, who want an alarm on each unit before the first tenants move in.

Security Alarm Installation in Toronto

Overview

We provide security alarm installation for homes and businesses throughout Toronto, including The Annex, Leslieville, The Beaches, High Park, and the rest of Toronto.

A security alarm system only protects a property if its sensors, control panel, and power supply are wired correctly from the start. We install and wire intrusion alarm systems for homes and businesses, including door and window contact sensors, motion detectors, keypads and control panels, sirens, and the low-voltage wiring that connects them, along with the dedicated circuit and battery backup that keep the panel running through a power outage. Electrovoltage works with homeowners, retail and commercial property owners, and general contractors on new alarm installations, expansions to existing systems, and rewiring jobs where sensors or panels were installed with undersized wiring or no backup power.

Why It Matters

Most alarm system failures aren’t sensor failures, they’re power and wiring problems: a control panel plugged into a shared outlet with no dedicated circuit, a battery backup that was never sized to actually hold the panel over during an outage, or door and window contacts wired with cable that wasn’t rated for the run and starts giving false signals within a year. Monitoring is only as reliable as the connection behind it too, a cellular or landline dialer needs a stable power supply to report a break-in or a power outage. We wire the panel, sensors, and backup power correctly the first time so the system is actually there when it needs to be, not just installed and hoped to work.

How Security Alarm Installation Works

  1. 1

    Site walkthrough & sensor planning

    We review your property, identify entry points and areas to cover, and plan sensor and keypad placement against realistic wiring routes.

  2. 2

    Power & panel planning

    We size the dedicated circuit and battery backup for your control panel, and confirm what wiring the sensor count and monitoring connection require.

  3. 3

    Wiring installation

    We run new low-voltage wiring for door/window contacts, motion detectors, and sirens, or work with existing wiring where it’s in good condition.

  4. 4

    Programming, testing & handover

    We install and program the panel and keypads, test every sensor and the monitoring connection, and confirm backup power holds before we leave.

What Affects the Cost

Century-home jobs in the west and east end typically cost more per zone than the panel work itself would suggest, since fishing wire through solid plaster walls and running a dedicated circuit to an unfinished basement often means extra time versus a modern build; condo in-suite jobs are priced lower per system since there’s no perimeter wiring and no dedicated circuit run beyond the suite’s own panel.

Cost depends on the number of doors, windows, and motion zones being covered, how much new low-voltage wiring needs to be run and how accessible that route is, whether a dedicated circuit is needed for the control panel, and whether the job includes monitoring setup or integrates with an existing panel.

Frequently Asked Questions

Does an alarm system in my Annex or Riverdale century home need to cover every window?
Not usually — we prioritize ground-floor and basement openings and add motion coverage for upper floors, since wiring every original window in a century home adds cost without adding much real protection.
I have a condo in Yorkville with building security already — do I still need my own alarm?
Most owners still want an in-suite system, since building fob access and lobby cameras don’t cover what happens inside your unit; we typically just add a keypad, balcony door contact, and a motion sensor rather than a full system.
Can you install an alarm system in a Leslieville or Beaches property I’m converting to a duplex?
Yes, we regularly wire each unit with its own independent panel and zones so you can hand a working system to tenants at move-in, which most landlords ask for as part of the conversion.
Do you install the alarm system itself or just the wiring?
We handle the full installation, sensors, keypads, control panel, and the wiring and dedicated power behind them, plus programming and testing before handover.
Can you add sensors to an alarm system that already exists?
Yes, we regularly extend existing systems, adding door, window, or motion sensors to spare panel zones, or upgrading the panel if the existing one doesn’t have capacity for more.
Does the control panel need a dedicated circuit?
It should. A control panel sharing a circuit with other loads is more likely to lose power unexpectedly, which is why we size a dedicated circuit and properly rated battery backup for every installation.
What happens to my alarm system during a power outage?
A correctly sized battery backup keeps the control panel, sensors, and monitoring connection running through an outage. We size backup power to your system rather than relying on whatever came in the box.
Do you connect the system to a monitoring service?
Yes, we wire and set up the panel to connect with cellular or landline monitoring services so break-ins and power issues are reported around the clock.
How much does security alarm installation cost?
Cost depends on the number of sensors and zones, how much new wiring needs to be run, and whether a dedicated circuit is needed for the panel. We provide a clear quote after reviewing your property.
