What to do if…
a windowpane is badly cracked or broken and may fall or leave the home unsecured

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy USA guide

Short answer

Move everyone and all pets away from both sides of the window and out of the possible fall path. Do not approach or touch the pane; arrange emergency glass repair or professional board-up, and call 911 if anyone is in immediate danger or a break-in may be in progress.

Do not do these things

  • Do not approach the pane to press, pull, tape, or remove loose glass.
  • Do not open or close the damaged window.
  • Do not slam nearby doors or create vibrations around the pane.
  • Do not stand beneath the window or allow anyone into the area outside it.
  • Do not climb a ladder, lean outside, or attempt an upper-floor repair yourself.
  • Do not let children or pets enter the affected room.
  • Do not walk through broken glass barefoot or begin cleanup while glass remains unstable.
  • Do not let an unsolicited repairer pressure you into an immediate decision or full upfront payment.

What to do now

  1. Move to a room away from the window. Keep people and pets clear of the inside area and any outdoor area where glass could land.
  2. Keep the affected room closed off. Close its interior door only if you can do so without going near the pane, and do not slam it.
  3. If someone may be inside unlawfully, a person is threatening you, anyone has a serious injury, or falling glass poses an immediate danger to people, move to a safer place and call 911.
  4. Look only from a safe distance. Note whether glass is falling, bowing out of the frame, missing entirely, or exposed at sharp edges. Do not test whether it is loose.
  5. Call an emergency glass repair or board-up service. Tell them that the pane may fall, whether it is above ground level, whether the opening is accessible from outside, and whether the frame also appears damaged.
  6. If you rent, contact the landlord, property manager, or emergency maintenance line now. Send a brief written follow-up and, only from a safe position, a photograph of the damage.
  7. If the home cannot be secured, lock the other exterior doors and windows without approaching the damaged area. Take essential items such as your phone, keys, medication, and identification, then stay somewhere safer until the opening has been secured.
  8. If the damage may have resulted from a crime that is no longer in progress and there is no immediate danger, use the published non-emergency contact route for your local police department.
  9. If someone has been cut, first move them away from the glass. Apply firm direct pressure with clean gauze or cloth if it is safe to do so, and call 911 for severe or continuous bleeding.
  10. Before temporary work begins, take photographs from a safe position. Keep messages, invoices, and receipts, and contact your insurer promptly if you may make a claim.

What can wait

Choosing the permanent replacement, comparing window types, cleaning close to the frame, deciding who was responsible, and resolving insurance coverage details do not need attention now. For the moment, focus only on keeping people clear, getting the opening secured, and retaining basic photographs, messages, and receipts.

Important reassurance

You do not have to handle unstable glass or make the window safe yourself. Keeping clear, preventing access, and arranging appropriate help are enough for the immediate situation.

Scope note

This guide covers immediate safety, temporary security, and the first contacts to make. Permanent glazing, frame repairs, structural concerns, tenancy issues, police reports, and insurance decisions may require appropriate specialist help.

Important note

This is general safety and property information, not legal, construction, insurance, or medical advice. Follow instructions from 911 or local responders and avoid any step that requires approaching unstable glass.
