Hi, I have just broken our rear door exterior threshold, any hints & tips on how to replace?
Welcome to the Bunnings Workshop community @CaneronE. It's brilliant to have you join us, and many thanks for your question about repairing a door threshold.
It sounds like a few pictures of the damage would help illustrate to our members what the exact issue is. Once they can tell what the damage is, I trust they'll be able to offer plenty of helpful solutions.
In the meantime, have a look through these helpful step-by-step guides: How to install a door jamb and How to fix a door jamb.
Please let me know if you need assistance uploading some images.Mitchell
