My doorstep is cracking below the brick. See images below. Can anyone tell me what I need to repair this (e.g. what mortar/cement to buy, tools etc?). Also, can I use the same thing to repair the cracked mortar between the paving slabs and the bottom edge of the house? Many thanks! Doorstep: Cracked mortar between slabs and edge of house:
You could try a readymix like cementstone general purpose, I have used that to tidy up steps before, screwfix sell it in tubs. Just scrape out the old crumbly stuff then put it in.
