How to Secure a Broken Door or Window After a Break-In

Make the property safe without destroying the entry-point evidence

Wait for police clearance before repair where evidence may exist. Then use a competent emergency contractor to restore weather protection, safe escape and meaningful resistance—not merely hide the damage.

Immediate priorities

  1. Isolate people and pets from broken glass, unstable frames and exposed wiring.
  2. Photograph damage only when permitted and without walking through evidence.
  3. Contact the insurer before non-emergency permanent work where the policy requires it.
  4. Use temporary boarding that cannot be easily removed from outside.
  5. Keep fire exits and necessary accessibility routes usable.
  6. Change or disable stolen keys, fobs, remotes, PINs and smart-lock access.
  7. Test the alarm contact after the opening is made secure.

Repair the system, not just the visible panel

Damage Inspect together
Forced door Door leaf, frame, hinges, strike, fixings, glazing, cylinder and surrounding wall
Broken window Frame, locking points, glazing specification, beads, restrictors and accessible handles
Patio or sliding door Tracks, anti-lift measures, interlocks, frame anchoring and lock engagement
Garage entry Panel, side tracks, emergency release, opener, remote controls and house-connection door
Do not create a new life-safety problem. Security work must not trap occupants, block emergency escape or conceal structural, electrical or gas damage.

Before paying the final invoice

  • Confirm the exact repair and product specification in writing.
  • Test alignment, locking, emergency operation and alarm contacts.
  • Obtain itemised invoices, photographs and warranty information.
  • Update household key control and insurer records.
  • Schedule a later whole-property review rather than over-fortifying only the damaged opening.
