How to troubleshoot a Cracked Window Pane
A cracked window pane needs prompt repair. This guide covers temporary fixes with tape and replacing the glass permanently.
Step-by-Step Fix
- Apply clear packing tape over the crack to stabilise the glass and prevent it from spreading.
- Remove the old glass by carefully prying out the glazing points and putty.
- Clean the frame and apply a thin layer of linseed oil or primer to the wood.
- Cut a new pane of glass to the same size and fit it into the frame carefully.
- Secure the pane with glazing points and apply a bead of glazing putty around the edge.
- Smooth the putty and let it dry for 24 hours before painting.
Common Error Codes

|---|---|---|
| Glass breaks during installation | Too much pressure or uneven frame | Use gentle pressure and ensure the frame is square. |
