If you’re wondering whether your home’s windows are secure, you're already thinking like a smart homeowner. Maybe you noticed that a window lock is broken. Maybe you just moved into an older house and you're not sure when to update some older, double-hung windows. Either way, checking the condition and security of your windows is absolutely a matter of safety.

Windows are one of the most common entry points for break-ins, so upgrading isn’t just an investment in well-insulated glass and frames; it’s also about peace of mind.

Homeowners Often Overlook Window Security

Only 17% of Baby Boomers and 14% of seniors considered security related projects last year, according to the 2025 U.S. Houzz and Home Study. The same study highlighted that Gen X was more inclined to invest in security with 21% of homeowners prioritizing these improvements. All said, the stated frequency of security upgrades is still significantly lower than interior decorating projects and bathroom or kitchen renovations.

From smart technology integrations to security cameras and home security systems with glass break sensors, we know there are many places to focus. And while all entry points to one's home should be critically considered, many homeowners focus at doorways, and leave it at that. "Like any building opening, windows are a common point of forced entry into homes, making locking systems and security features very important," shares Matt Gibson, director of marketing for the U.S. Windows and Doors division of Cornerstone Building Brands.

Windows that have passed forced-entry resistance tests tend to offer more than just tougher locks. They typically include features like self-latching systems, reinforced frames, and laminated glass.

Gibson adds, "Windows that are tested for forced entry resistance and feature impact-resistant glass that is very difficult to penetrate even with repeated blows from bricks or hammers, provide the peace of mind homeowners are looking for. For homeowners looking for advanced security features, choose self-latching locks for increased protection."

One example he gives is Simonton® Windows and Doors, which are designed with both appearance and protection in mind. If you’re not sure what kind of windows you have or how well they’d hold up to forced entry, that’s a good reason to take a closer look.

Signs It’s Time to Update Your House Windows

Maybe you're not sure whether replacing your windows is worth it. Here's when it might be:

  • Your window lock is broken or the latch no longer aligns with the frame
  • You feel a draft even when the windows are closed
  • Condensation builds up between double-pane glass
  • The windows stick or won’t stay open (or closed)
  • You’ve noticed more outside noise getting in than usual
  • The frames are cracked, rotting, or warped
  • You want to add features like laminated or tempered glass for safety

These problems can affect more than just security. They impact energy efficiency, comfort, and resale value too.

If you’re already doing other home improvements, updating your windows can be a smart upgrade to roll in.

What features matter for window security?

Your home's window security isn’t just about having a lock or a strategically pointed flood light; it’s about how the entire window system is built. Some features to consider when shopping or evaluating your current setup:

  • Self-latching locks: These automatically lock when the window closes, so you don’t forget.
  • Impact-resistant laminated glass: Impact-resistant windows are to break, even under repeated hits.
  • Tempered glass: Shatters in small, blunt pieces rather than dangerous shards.
  • Window security film: An added layer (like window glazing) that makes glass harder to break.
  • Window security screens: Stronger than regular screens and harder to cut.
  • Casement windows: Often more secure than sliding windows due to their locking mechanism.
  • Window sensors: Trigger alarms when opened or broken, often used with home security systems.
  • Window security bars: Visible deterrents that add physical protection, though not for everyone’s style.

If your current windows don’t offer any of the above, it's worth considering a replacement. Especially in older homes, older-style latches and glass may not stand up to modern break-in methods.

FAQ

Are sliding windows less secure than other styles?

They can be, especially if the lock is worn out or the track is loose. Compared to fixed windows, sliders often rely on a window latch mechanism that can wear down or be bypassed with a little force. Adding a security bar or pin lock can help, but if the frame is old or bent, a full replacement may be the better option.

Do I need a security system if I upgrade my windows?

It depends on your comfort level and neighborhood. New windows with reinforced glass and upgraded locks are a solid step forward. That said, window sensors can offer real-time protection—especially ones that detect vibrations or breakage—can give you more quick feedback if something goes wrong. Many homeowners do both: physical upgrades paired with tech-based monitoring.
