Yes, in most cases a sinking flagstone patio can be releveled without tearing out the whole thing. The stones are lifted, the base underneath is repaired and recompacted or regraded for drainage, and the same flagstone is reset. Whether it's worth doing depends on how much of the patio is affected and whether the flagstone itself is still in good shape.
How the patio was originally built changes how straightforward this is. Dry-laid flagstone set in sand or stone dust can usually be pulled up piece by piece, the base corrected underneath, and the same stones reset in roughly their original layout. Mortared flagstone takes more care, since the mortar bond has to be broken cleanly without cracking the stone before the base can be reworked and the flagstone reset or remortared.
Releveling only fixes the problem if the base is actually the cause. If the flagstone itself is cracked, delaminating, or badly weathered, resetting it on a good base won't undo that damage, and those individual pieces may need to be replaced rather than reused. That's a separate issue from settling, and it's worth telling apart before deciding on a repair.
When we look at a sinking flagstone patio, we're checking how many stones are affected, how solid the flagstone itself still is, and what's actually going on underneath, drainage, erosion, or a base that was never compacted right. We aim to fix what's causing the sinking, not just reset the stones back on top of the same problem.
