You can see on the attached picture that the top part of the wall needs some looking after. Its non-standard construction so the red bit is steel as far as I am aware.
I am not sure what I ask a tradesman to do here. Prep and repaint? If so, with what type of paint?
I know a good tradesman should know the answer to these but it would not hurt to know myself so I am not being taken for a ride.
Also cost estimates on something like this?
Thank you in advance
