Steps & Stairs in Somerville, Massachusetts.

Steps heave before anything else because they concentrate load on a small footprint. Set on clay-rich glacial till capping the drumlins over Cambridge argillite bedrock, which drains slowly and demands engineered footings, that risk is real — so we excavate below frost, compact a structural base, and bed each tread so it cannot rock, settle, or drift out of line through the winter.

Solid granite treads, stacked bluestone, or dry-set fieldstone risers each get a different build sequence, matched to the restored Second Empire and Italianate mansions on Spring Hill and Prospect Hill above the city's signature Victorian two- and three-family houses of the house they serve.

If you are coming to us with a plan already drawn, we build it as drawn. We read grading and layout sheets fluently, hold the detail, and keep the designer informed at each milestone — the way we work with Jonathan Keep Landscape Design across Massachusetts.

The part nobody photographs: where the pallets sit, where the excavator tracks, and what the property looks like on a Friday afternoon. In Somerville we plan all of that up front and hold the schedule we gave you at the start.

Nothing gives a stone contractor away faster than a run of steps. We survey the grade across a compact grid draped over seven drumlin hills that slope to the Mystic River lowland, calculate the run so the risers divide evenly, and set every tread to that number — no fudging the last step at the top, which is the classic tell of a rushed job.

The foot notices a riser off by a quarter inch even when the eye does not. On garden stairs we keep risers low and treads generous, so the climb feels like part of the walk.

Two properties on the same Somerville street can differ by a third in price, and it is almost never the stone. It is access for machines, the base depth clay-rich glacial till capping the drumlins over Cambridge argillite bedrock calls for, how much water has to be managed, and whether existing planting has to be protected while we work.

You get an itemized scope after we walk the property — what is included, what is not, and where the money actually goes. No allowances that quietly become change orders halfway through.
