New windows. No window cill horns

[Benway]

Hi.

I'm installing new windows that don't have cill horns so will need to adjust the brickwork. I know the "proper" way is to totally remove the brick but I can never get the mortar a similar colour and my bricklaying skills are terrible and I just seem to get most of the mortar on the brick face. With this in mind would it be OK to cheat?

Cut the existing brick at the red line to clean it up. Insert an ickle brick with no mortar line to the existing, just mortar top and bottom? Maybe a little clear silicone to seal stuff up?

Cheers

Check that the original window was not installed far too forward in the reveal because if a sil that was too short.

That's the old window. New window the cill will flush with the width

a bit of mismatched mortar will not show much.

you can mortar in your new bit of brick while the window is out, giving you good access to squidge your mortar in and clean up. If it's a dry, sunny day, small smears on the brickwork can be taken off with a dry, stiff brush as soon as they dry. Mortar hardens by being damp, and in sunlight, thin smears dry so fast it has no strength. So spray the cavity with water before bricking up, and leave the face dry, or cover it with masking tape.

Do not leave smears or snots in place to get wet with rain, which will strengthen them and cement them into place.
