Best sealant for sealing outside of door frame

[JimDogweed]

We have a small gap (worse on the left side) running around the door frame of our 1900 terraced house. The frame is wood.

What's the best type of sealant to fill this gap? Would an outdoor silicone sealant like this be best?

Thanks in advance.

Id be worried about ruining your lovely period brickwork.

Dont get any on it, whatever you use.

I would think that sealant would work ok, dont see why not.

Looks to have rotted trim, replace it, no gap to fill.

It's 100% not rotten - It all seems really solid. Hoping to seal it to prevent any weather damage and prevent rotting.

next time you strip the door and frame, to repaint it, prise off that bit of architrave. It might be that the door and frame have moved in the last 110 years. you can perhaps refix it as a better fit.

It's in a bit of a porch I think so not very prone to rot.

The rot down the edge is quite clear, needs replacing.
