Bluestone, granite, brick, and pavers — built on a base that survives frost heave, not on a base that moves every March.
A patio that heaves, dips, or puddles is a base failure, not a surface failure. In Connecticut, that means excavation below the organic soil, a compacted gravel base (typically 6–12 inches depending on load and drainage), edge restraint that actually holds, and a slight pitch away from the house so water leaves instead of pooling. A quote that prices the stone but waves at the base is pricing a re-do.
De-icing salt is brutal on masonry surfaces, especially softer stone and brick. A good mason will tell you which materials tolerate salt, which need sealing, and how to winterize a new patio in its first year — and a quote that ignores salt on a front walk in Connecticut is a quote written somewhere warmer.
