How do you secure basement windows like this?

I have basement windows similar to the ones in this picture


. I want to make them more secure but not sure what the best approach is. Any tips or ideas would be really helpful.

I’m looking for advice on this too.

You could use slotted electrical strut cut to size and mount it across as bars. Works well.

I did something similar for my shed windows. Painted the strut black, and it blends in nicely. It’s secure and doesn’t look bad from outside.

If you have the budget, glass block windows with a screened vent are a great option.

If not, you can go for burglar bars with heavy-duty screen. For the cheapest fix, you could screw the window shut by attaching screws into the top and side casings to stop it from opening.

Be careful though. If this is a basement with people living in it, those fixes might not pass inspection. Many building codes require basement windows to allow easy exit in case of emergencies.

If someone’s living down there, especially as a rental, those windows probably won’t meet code at all. Ventilation windows like these won’t cut it for safety requirements.

These windows aren’t meant to be exits, though. They’re too small for that.

I recently installed a glass block window with a vent myself. The window was about $150, and it wasn’t hard to do if you’re handy.

Does this side of the house get much sunlight? That could make a difference in how you approach it.

If you live in a safe area, simple fixes might be enough. You could use frosted vinyl to make the glass opaque and maybe add a metal bar like Unistrut across the window to discourage break-ins.

Most burglars avoid basement windows because they’re harder to get in and out of. They usually prefer doors since they can escape quickly if needed. Making it unclear what’s behind the window (like frosting it) could make them move on to an easier target.

Check out AWG adjustable window guards. I bought some from a big box store. They fit on the inside of the window and can expand to cover it completely. Just swap out the screws they include with stronger ones because the ones they provide can strip easily. You can also install an exterior burglar bar with one-way screws for extra security.

This setup worked well for me. The harder you make it to break in, the more likely someone will move on to an easier target.

Adding tint to the windows or putting up a curtain can also help by blocking the view inside.

Claymore… just kidding. But seriously, bars or reinforced glass are good options.

Here’s an idea I’ve seen before:

It’s an L-bracket with two slots drilled into it. When you want to open the window, you push the bracket toward the window so the screw heads go through the larger slot. But if someone tries to push the window open from the outside, the bracket stops it.
