What material and method to use above window

[NorthBristol]

Hi, DIY time for me, like many others. I've got this going on above my ground floor windows:

Should I (a) fix this little spot?
(b) dig it all out and start again
(c) do something else
Also, what material should I use to do the repair?
Grateful for any advice
Thanks

Hi North Bristol, rake it out. then trim it off with white upvc quad. Will fit perfectly to the frame and brick line using plastic glue and finish off with silicone. Nice quick cheap job. Hope this helps.

Bit of mortar if you have it, or use mastic and blend it in with your thumb.
