Frequently Asked Questions
Can I install window bars instead of replacing the windows?
Bars provide excellent protection, but they often complicate your escape plan. You must ensure that any bars you install have a quick release mechanism from the inside. Without this, you might be trapping yourself in the house during an emergency.
What is the most secure style of basement window?
Hopper windows are generally the top choice for security because they have fewer moving parts and smaller openings when tilted. Since they hinge at the bottom and open inward, they are difficult to force open from the exterior. Make sure the hinges are robust and mounted securely to the interior frame.
How much do secure basement windows typically cost?
You should expect to pay between $300 and $700 per unit depending on the material and glass type. Custom sizes or high-grade security glass will naturally push you toward the higher end of that range. Always factor in an additional $150 to $300 for professional labor if you are not comfortable drilling into concrete.
Will security windows prevent my basement from getting damp?
A new, well-fitted window helps significantly by providing an airtight seal. If your current windows are drafty or warped, water is likely seeping in during storms. A proper installation includes high-quality flashing to direct moisture away from the foundation wall.
Is tempered glass just as safe as laminated glass?
Tempered glass is stronger than standard glass, but it is designed to shatter into tiny pieces upon impact. While this prevents large, jagged shards, it leaves a gaping hole for an intruder to step through. Laminated glass is the better security choice because it stays in one piece even after it breaks.
