How Long Does a Break-In Take? The Answer Should Change How You Think About Home Security
July 31, 2026
Ask most homeowners how long a break-in takes, and you get an intuitive answer shaped by what they see in films and television: a prolonged event, an alarm that wails, a tense standoff, an eventual police arrival.
The data tells a very different story.
The average residential break-in in Toronto is over in under 10 minutes from first approach to exit. Entry through a standard glass window takes seconds. The search takes three to five minutes. Exit takes seconds. The entire event is usually over before police are even dispatched.
That timeline has a direct and uncomfortable implication for most residential security systems, and understanding it leads to a fundamentally different approach to what security measures actually matter.
The Real Numbers: How Long Each Phase Takes
Entry: Under 60 Seconds
When a criminal has selected a ground-floor window as their entry point, the actual entry takes under 60 seconds in most cases. Standard residential glass breaks in a single strike. The sound lasts less than a second. The opening is immediate.
If they need to reach through to open a window latch or door handle, that adds a few more seconds. If they are climbing through, slightly longer. But entry through standard glass takes seconds, not minutes.
Door kick-ins through unreinforced frames take a similar timeframe: one to three strikes in most cases, under 10 seconds.
The Search: Three to Eight Minutes
Once inside, an experienced burglar follows a sequence that has been optimized over time. Master bedroom first, where jewellery, cash, and small valuables are most commonly stored. Home office or study next, for electronics and financial documents. Main living areas for portable electronics. The search is fast, systematic, and destructive.
In a typical Toronto home, the search takes between three and eight minutes. Smaller properties take less. Larger properties with more rooms and more concealment options may take slightly longer, but experienced burglars do not linger. Time inside is exposure, and experienced criminals minimize it.
Exit: Under 30 Seconds
Exit is faster than entry. They leave through the nearest convenient point, usually the same entry point or the most accessible exterior door. The goal is to leave the property as quickly as possible once the search is complete.
Total Elapsed Time: Under 10 Minutes
From the first approach to being two streets away: under 10 minutes in most cases, and often significantly less. The entire event fits inside a window of time that most people would not consider meaningful.
Now Compare That to Your Security System's Timeline
Your alarm triggers at entry, approximately 30 to 60 seconds into the event.
Your monitoring centre receives the alert within another 30 to 90 seconds. They attempt to contact you. You may or may not answer quickly.
The monitoring centre dispatches police. In Toronto, average police response time to a residential alarm ranges from 10 to 20 minutes, depending on call volume, priority classification, and patrol unit proximity.
By the time a police officer arrives at your property, the entire event has been over for anywhere from 5 to 15 minutes. The criminal is gone. The bag is packed. Your alarm is still ringing.
Your camera recorded everything. Your alarm documented the breach. Your monitoring centre has a timestamped log of every step in the response chain. And none of it stopped anything.
The Implication: Two Different Types of Security
This timeline reveals that residential security measures fall into two categories that operate in completely different timeframes.
Response-Based Security (Works After the Breach)
- Alarm systems: trigger at entry, initiate a response chain that concludes 10 to 20 minutes later
- Cameras: document the event in real time, provide footage for investigation after the fact
- Monitoring centres: receive alerts and dispatch police, adding 2 to 5 minutes to the response chain
- Police: arrive after the event is over in most residential break-in scenarios
These measures have genuine value. They deter some criminals. They provide evidence. They support insurance claims. They are necessary components of a complete security system.
But they do not stop a break-in in progress. They respond to one.
Prevention-Based Security (Works at the Moment of Entry)
- Impact-resistant glazing: physically prevents entry through glass, operating in the same second as the breach attempt
- Reinforced door frames: physically prevent kick-in entry, operating at the moment of the attempt
- Visible deterrents: may cause a criminal to select a different target before the attempt begins
Prevention-based measures operate in the timeframe of the event itself. They do not wait for a response chain to complete. They are the difference between a home that documents a break-in and a home that stops one.
What the Timeline Means for How You Should Invest in Security
Most residential security spending in Toronto is heavily weighted toward response-based measures. Alarm systems. Cameras. Monitoring contracts. These are the products most heavily marketed and most widely adopted.
Prevention-based physical measures, particularly glass protection, are chronically underfunded despite being the category that operates in the right timeframe.
The implication for investment priority is clear: the physical barriers that operate at the moment of entry should be the foundation of a home security system, not an afterthought. Detection and response measures add genuine value on top of that foundation. Without it, they are documenting events they cannot prevent.
STRIKEGLASS: The Measure That Operates in the Right Timeframe
STRIKEGLASS from 416 Security Solutions is a security glazing system that installs over existing windows and glass doors, making them 300 times stronger than standard glass.
When a criminal attempts entry through a STRIKEGLASS-protected window, here is what happens in the first 60 seconds:
- The first strike does not produce an entry. The glass holds.
- Subsequent strikes are required. Each adds time, adds noise, and adds exposure.
- The alarm triggers. Neighbours may hear the sustained impacts. The risk calculation changes.
- Within 15 to 30 seconds of unsuccessful entry attempts, most residential burglars abandon the attempt.
The entire timeline collapses. The 10-minute event becomes a 30-second failed attempt. The criminal moves on. The home is intact.
STRIKEGLASS installs over existing glass without window replacement, is optically clear, and most homes are completed in a single day. It also delivers UV protection, noise reduction, and improved insulation as year-round benefits that operate entirely independently of its security function.
Building a System That Covers Both Timeframes
The right residential security system covers both timeframes: prevention at the moment of entry and response in the minutes that follow.
- STRIKEGLASS on ground-floor windows and sliding glass doors: prevention at the moment of entry
- Reinforced door frames: prevention at the moment of a kick-in attempt
- Motion-activated exterior lighting: deterrence before the attempt begins
- Professionally monitored alarm with glass break sensors: detection and response chain initiation
- Exterior cameras: documentation and deterrence
In this system, STRIKEGLASS and reinforced frames operate in the seconds that matter. Everything else operates in the minutes that follow. Together, they produce a home that is genuinely difficult to breach and thoroughly documented if any attempt is made.
Frequently Asked Questions
How long does it take to break into a house through a window?
Standard residential glass breaks in a single strike, which takes under a second. Entry through the opening, depending on the window size and position, typically adds 10 to 30 seconds. Total entry through a standard ground-floor window takes under 60 seconds in most cases.
How long does it take the police to respond to a home alarm in Toronto?
Average police response to a residential alarm in Toronto ranges from 10 to 20 minutes from dispatch, depending on call volume, priority classification, and the location and availability of patrol units. This timeframe is the norm, not an exception, and residential security systems should be designed with this response window in mind.
Does STRIKEGLASS actually stop a break-in or just slow it down?
In practice, STRIKEGLASS stops most residential break-in attempts at glass entry points because burglars operate within strict time constraints. When standard entry through glass is not achieved within the first few seconds, and sustained effort is required instead, the risk calculation changes completely. The alarm is active. Noise is ongoing. The concealment advantage is diminishing. Most criminals abandon the attempt well within a minute and move to an easier target.
If a break-in takes under 10 minutes, is an alarm system even worth having?
Yes. An alarm system adds deterrence value through visible signage and monitoring indicators. It initiates the police response chain as early as possible. It documents the event. And in the cases where STRIKEGLASS or other physical barriers extend the entry attempt beyond what a criminal is willing to sustain, a faster alarm response can make a meaningful difference. Detection and prevention work best together, not as substitutes for each other.
The Bottom Line
The average home break-in in Toronto is over in under 10 minutes. Most residential security systems are optimized for the 10 minutes after that.
The only security measures that operate in the right timeframe are physical barriers at entry points. STRIKEGLASS on ground-floor windows and sliding glass doors is the measure that closes the gap between the start of a break-in and when any response-based system can act.
Understanding the timeline changes everything about how security spending should be prioritized. Prevention first. Detection second. Response third. In that order, in a home that is genuinely difficult to enter, all three work together to produce an outcome that works in your favour.
