What to do if…
you return home and find a window screen removed or a window left slightly open when you know you closed it

Short answer

Assume it could be a break-in: do not go inside—move to a safer place and call 911 if there’s any chance someone is still inside or you feel unsafe.

Do not do these things

  • Don’t enter to “check quickly” or shout into the home.
  • Don’t touch the window, screen, latch, or frame if you may report this (you could disturb evidence).
  • Don’t confront anyone, search the house, or try to “secure the window” first.
  • Don’t let curiosity pull you closer to the window/door once you’ve noticed something off.
  • Don’t walk around the home if it puts you in a vulnerable spot (tight side yards, back gates, blind corners).
  • Don’t post your situation or address publicly while you’re outside the property.

What to do now

  1. Back away and create safety. Step away from the window/door. Go somewhere safer (a trusted neighbor’s home, a public place, or inside your locked car).
  2. Call the right number (if unsure, choose 911):
    • Call 911 if you think a crime may be in progress, someone might still be inside, you saw/heard anything suspicious, or you feel in danger.
    • If you’re confident it’s not in progress and you’re safe, call your local police non-emergency number (varies by city/county; in some places, requests may be routed through 311 or another local service line).
  3. Tell dispatch exactly what you observed (from a distance). Example details:
    • “Window screen removed” / “window left slightly open”
    • which side of the home / floor level
    • whether you see any movement, lights, or open doors
    • whether anyone who should be inside is unaccounted for
  4. If someone else might be inside (roommate, family, cleaner): call/text them from your safe location. If you can’t confirm they’re safe, tell dispatch and treat it as urgent.
  5. Do a quick “safe-distance scan,” not a search. From where you are (without approaching), look for anything else obviously unusual (other windows open, forced entry, unfamiliar vehicle). Don’t go closer to “get a better view”.
  6. Preserve the scene. If you do end up entering later (for example, after police advise), avoid touching the window area and don’t clean up until police have said it’s okay.
  7. Optional, only from safety: check a doorbell/camera feed or alarm app from your phone if it helps you give clearer information. Don’t approach the property to improve the signal or camera view.
  8. After officers respond or you’ve filed a report: get the report/case number and write down what you remember while it’s fresh (time you arrived, what looked changed).

What can wait

  • You don’t need to decide right now whether it was “definitely” a burglary or an accident.
  • You don’t need to start repairs, change locks, or make insurance calls until you’re safe and you’ve gotten guidance from police (if you reported it).
  • You don’t need to inventory every item immediately—focus on safety and basic documentation first.

Important reassurance

Your brain may try to “explain it away” so you can go back inside. That’s normal. Choosing safety—stepping back, calling for help, and not entering—protects you in the worst case and costs little in the best case.

Scope note

This guide covers immediate first steps only (minutes to the first hour). Longer-term actions (repairs, prevention, insurance, follow-up) come after the immediate risk is resolved.

Important note

This is general information, not legal advice. Non-emergency numbers and response procedures vary by location—follow dispatcher instructions and local law enforcement guidance.
