Not any more than you worry about someone kicking in your shit-tacular cheap door, or drilling the lock out. Homes aren't often fortresses; you'd build differently if you lived in an unsafe, unstable area. Lots of homes in America have no property walls or fences, either--probably the supermajority of them. I assume that's also true for Canada, especially in uh, the woods.

I have a full pane glass door into my shop. I’m definitely replacing it for this reason. Someone could absolutely break in by other means and there’s other windows big enough for a person (by regulation), but somehow a big door full of glass seems too inviting.

That said many stores have big glass windows and their best goods out front. But on the other hand, other stores also have security doors that enclose everything when it’s closed. I might be being too paranoid, but the same concern applies to even locking your door. A locked door only keeps the honest folks out is what they say, so should we do away with locks completely? Obviously people find some utility in them despite their inherent weaknesses.

The company I work (manufacturing) has facilities in not-so-nice areas. We have had break-ins that used sawzalls or other large power tools to remove the entire door frame of steel doors (set in concrete walls).

If someone wants in, they're getting in.

All the break-ins failed to get anything of value, however... everything gets put away, there are cameras, and we are VERY friendly with people living in the area (imcluding employing as many locals as we can).

Of all the "security" measures, people living in the area were the best defense. We take care of them, they take care of us.

You'd need to have pretty small windows for that not to work. Or they could just drill a hole in the wooden walls.

I was worried. It hasn't been a problem yet. I put some CCTV cameras up though.

Big dog helps.
