Need to Remove and Replace a Hook that is in Concrete
If it were really concrete, an expansion eye bolt is an obvious choice:  Where you drill a hole, clean it out (without breathing the dust), and tighten.

But you've got brick which is crumbly, and you want it secure against theft and pull out.  Thus you should consider drilling a slightly larger hole, cleaning out yet better, and setting a new bolt with epoxy.

Or get a bolt with plate, and multiple tapcon type brick anchor screws to spread the load out a bit in the brick:


The old bolt will likely pull out with a pry bar or screwdriver with a twist.  You may be shocked how easy it comes out of mortar.

If you need to hire, hire a "handyperson" or "handy".
