The crack is likely where a sand/cement mortar, (with zero movement accomodation)
has been used to fill the gap between the brick/blockwork and the wooden window frames,
and has delaminated from the former.
Is this property a 'keeper'?
If you only envisage being there a couple of years, your suggestion is valid.
If you see it as a long term home, maybe invest a little more in the materials.
The labour will not be too different.
Measure the crack.
Lets work with 2mm.
If your exterior filler has only a 10% movement accomodation, you will need a 20mm wide fillet of material.
The Soudal Fix All is probably closer to 40%, meaning a 5mm wide fillet.
It’s a keeper and yes I’d like to invest in materials / techniques to make sure I’m not back here in two years time doing the same thing again! So thank you for your suggestions and I’ll follow your lead.
