Concrete walkway trip hazzard
 

My walkway has settled where an expansion joint has separated and one side has gone down about one inch, creating a trip hazard.
I would like to find a way to raise the edge of that slab back up. I believe that if I grind the edge off or replace the slab, it will not look good and may affect the value of my property in case I sell.
Does anyone know someone who can correct this problem without making it look odd?
See photos.
Thanks

Who did the original work?
If it came with a new house call Home Warranty. Even if it is out of warranty they can advise someone to do the repair.
