Repairing doorway after new front door installation

[Yukster]

I had a new front door fitted. My builder proposed to repair my doorway with a pole filler. What is a pole filler?

I would ask my builder but his English is basic and he isn't very clear at the best of times.

Can someone explain what is a pole filler? Or does he mean polifilla?

Also how could I prevent the joing from cracking? I used caulk in the past around my windows and after w hold a crack formed. I'd rather not use and architrave.

I guess you mean polyfilla.
Polyfilla is not as good as some other modern fillers imo.
Use toupret powder filler. 2kg box will do.
Masking tape will keep the door clean and stop any accidental scratching.
Fill. Sand.
You will need a trim of wood or plastic especially on the right side to bridge door edge as that will always crack.
Stick on with with something like stixall
