Fifty year old CBS house with a crack in a corner where two windows meet which are separated by a steel post. The concrete/stucco has separated from the post and water penetration has rusted it and caused the crack. Two hurricane awning fasteners are now loose in the wall from the deterioration and will not be secure should the awnings need to be fastened down.
A couple of contractors have said that they can chip away a bit and put epoxy down in there to solve the problem. Others have said the whole area needs to be cut away, formed and poured, while another said that one of the windows has to go, eliminating the post and blocking in the opening. Some say that if it is cut away, reformed and poured new, that it won't hold up long term and will eventually pop out.
Can anyone offer any concrete suggestions on the best way to approach this?
