Colorado Rose Flagstone joint repair (on concrete pad)

My front walkway is in need of some repair. The walkway is Colorado Rose Flagstone, on a concrete pad. The walkway continues to a flagstone portico at the entrance. I have contacted a few places and the answer I get back is "the joints will continue to bust out over time" - they recommend I replace the flagstone with a straight concrete walkway and entrance. Obviously I do not wish to do this and diminish the entrance to a 1939 Colonial revival. Any thoughts or contractor recommendations would be appreciated.
