How to Prevent Break-Ins: Securing Windows and Deterring Burglars

When renters think about their apartment’s security, their first thought is likely the front door. But they often overlook windows, which are just as important, if not more so. Burglars often look for the path of least resistance, and windows are high on that list, especially if they’re unlocked, poorly secured, or hidden from view. 

If you’re wondering how to deter burglars and make your place feel safer, turn your attention to your windows. The good news? You don’t have to spend a fortune or drill into your walls (especially if your lease doesn’t allow it). We’ve collected some practical tips to help keep your apartment safe from break-ins. 

Why windows are a common target 

Windows are usually easier to open or break than solid doors, especially in apartments where they may be older or not built with security in mind. Ground-level windows are the most vulnerable, but upper-story windows aren’t off the hook if there’s a fire escape or an easily accessible balcony. 

Burglars also prefer windows because they tend to be out of sight, especially those located at the back or on the sides of buildings. Less visibility means less chance of getting caught. That’s why it’s important to secure all your windows, not just the ones you think are easy to reach. 

How to deter burglars with window security 

1. Lock every window  

You’d be surprised how many people leave windows unlocked, especially during warmer months. Make it a habit to check your locks before you leave home or go to bed. If the existing locks feel flimsy, talk to your landlord about an upgrade or invest in budget-friendly window locks that don’t require drilling. 

2. Add window sensors or alarms 

Do you want to know if someone’s trying to sneak in? Window sensors are a simple way to deter burglars from breaking in through a window. These small devices trigger an alarm if the window opens unexpectedly.

3. Use window security film 

This clear adhesive film reinforces glass, making it harder to break. A burglar trying to smash through your window will have a much tougher time and might give up altogether. It’s an affordable and subtle way to add a serious layer of security, especially for renters who can’t replace windows or install bars. 

4. Block the view inside 

If burglars can’t see what’s inside, they’re less likely to take the risk. Keep blinds or curtains closed, especially when you’re not home. Consider installing privacy film that lets light in but keeps prying eyes out. 

5. Add a security bar or rod 

For sliding windows or patio doors, a simple bar or rod in the track can make a big difference. Even if someone gets past the lock, the bar stops the window from sliding open. It’s a low-cost fix that takes seconds to install and remove. 

6. Light it up 

Burglars hate bright lights. Motion sensor lights around windows — especially those that are hidden from view — can be a major deterrent. If you’re in an apartment, you may not be able to install outdoor lighting, but even indoor smart bulbs on timers can make it look like someone’s home when you’re out. 

Extra tips to keep in mind 

Here are some general tips to keep in mind so your apartment stays safe: 

  • Don’t advertise your belongings. Do you have a big TV or expensive gear by the window? Try to keep it out of direct view. Burglars are more likely to break in when they see something worth stealing. 
  • Get to know your neighbors. If you have someone nearby who can keep an eye out when you’re gone, that’s a major win. 
  • Avoid posting on social media when you’re away. Posting your vacation pics while you’re on vacation can be an open invitation for burglars to check out your place. 
  • Report broken locks or damaged windows ASAP. Let your landlord know right away so it gets fixed before someone takes advantage.

Learning how to deter burglars and creating a secure living environment is about layering different strategies to make your home an unattractive target. No single measure will guarantee complete protection, but combining several approaches may help you stay safe. Remember, most burglars are looking for easy targets. By taking these steps, you’re reducing the risk of a break-in. 

The key is finding the right balance between security and comfort. You want to feel safe in your home without making it feel like a fortress. Start with the basics like making sure you’ve locked your windows and the view inside is blocked, then add other measures based on your specific situation and budget. This way, you’ll be well on your way to keeping your space safe and sound.
