Stone masonry covers work built from natural stone or manufactured stone veneer: retaining walls, foundations and foundation repair, veneer facades, chimneys and fireplaces, walkways, patios, and fieldstone walls that hold up New England winters. It's a different trade from brick or block work in practice, since every stone is a different shape and size, so the mason is fitting and leveling by eye as much as by measurement. Waterbury's older neighborhoods have a lot of original fieldstone foundations and retaining walls, which means this category also covers a fair amount of repair and rebuild work, not just new construction.
Before hiring, ask to see photos or an in-person example of stone type you want (fieldstone, granite, bluestone, or manufactured veneer), since technique and cost vary a lot between them. Get a written scope that specifies drainage and backfill for any retaining wall over a couple feet tall, because a wall that fails is almost always a drainage problem, not a stone problem. Confirm whether the crew pours footings below the frost line for anything structural, and ask how they handle mortar joints in freeze-thaw conditions, which is a real factor here. A contractor who asks about drainage and frost depth before quoting a wall is usually the one who's dealt with a failed one.
